garlic

aka allium sativum

Garlic is one of the most commonly used vegetables in cooking. It offers a variety of health benefits and can be consumed in a myriad of ways including cooked, preserved in oil or even eaten raw.

variations

There are about 11 different types of garlic. They are classified as “hard neck” or “soft neck” variations.

light

full sun

Plant in a place where they can get 6 – 8 hours of sun

water + feeding

not too thirsty

It’s best to water deep, but garlic only requires between a half to a full inch of water per week.

toxic

yes and no

Garlic is toxic for cats and dogs, but delicious for humans

size

small-ish

Average garlic bulbs have about 6-10 cloves, but their foliage can reach up to 2ft in height.

pro tip

plant in the fall

Plant your garlic 4 – 6 weeks prior to first frost

fun fact

keeps more than vampires away

Garlic is known as one of the healthiest foods, containing healing properties such as: anti blood coagulation, antioxidant, antiviral, antimicrobial, lowers cholesterol, reduces blood pressure, anticancer properties and can be used to help fight off colds.

beyond the basics

  • soil + planting

    Plant garlic cloves 4 to 8 inches apart, and about 2 inches deep. Be sure you plant the cloves with the root side pointing down. Your garlic needs well-draining soil, such as Miracle-Gro® All Purpose Garden Soil. Add a little compost to bump up the nutrients of soil.

  • companion planting

    Garlic can be planted next to other veggies such as beets, celery, lettuce, potatoes, strawberries or even tomatoes. It’s best to avoid planting near peas or beans.

  • harvesting

    Once your garlic has sprouted some leaves, and a few of the lower leaves have turned brown, your garlic is ready to pick. The only way to tell is to pick a few bulbs as a test. If the cloves have filled the skin, they’re ready to harvest. Be sure not to let them wait too long once you notice the lower leaves browning, otherwise the protective layers around the cloves will be too thin. This means the garlic won’t store well.

  • pest control

    White rot is a common disease that can wipe out an entire garlic crop. This is identified by little poppy seed sized bumps on the stem, and white fuzzy growth on the bottom of the bulb. If left untreated it can remain in the soil for many years. Keep an eye out for symptoms from mid-summer to autumn. If you’re noticing this has been a problem where you’re planting, apply a fungicide. For best results, apply the fungicide in a 6 inch band over the planting trench. This should happen immediately before planting.

troubleshooting

  • why is my garlic drooping and brown?

    Could be time to harvest. When garlic is ready to be harvested, a few of the bottom leaves will turn brown and droop. The easiest way to tell if your garlic is ready to harvest is to count back. Garlic needs about 240 days to mature.

  • no, really why is my garlic drooping?

    Nutrient problems. Your soil could be lacking in some key nutrients like nitrogen, potassium, calcium, and magnesium. Consider using a plant food like, Miracle-Gro® Shake ‘N Feed® Tomato, Fruits & Vegetables Plant Food.

  • why is my garlic not sprouting?

    Extreme weather conditions. Sometimes after a particularly harsh winter, garlic crops can come out a bit crumpled or very small. One way to prevent this is to water and mulch immediately after planting. Be sure not to add too much mulch though! Too much mulch applied too late in the season will insulate the ground and delay it from going dormant. This can cause root rot once the real cold weather sets in.

fun fact

technically a biennia

It’s a 2-year plant that produces leaves in the first year and a flower stalk in its second year.

beyond the basics

  • companion planting

    Kale works well when planted by artichokes, beets, celery, cucumber, lettuce, onion, peas, potatoes. Avoid other brassicas being planted alongside kale. These include broccoli, kohlrabi, cauliflower, brussels sprouts, and Swiss chard.

  • Harvesting

    When your kale’s leaves are about the size of your hand, it’s ready to harvest. Be sure not to pick more than a third of your plant’s leaves at a time.

  • pest control

    What are these little white flies? They are literally Whiteflies. They drink sap and excrete a sticky ‘honeydew’ which also encourages mould. Use sticky traps or Ortho® Bug B Gon® ECO Insecticidal Soap to keep your plants healthy.

pro tip

Leave lots of room

Elephant ears need a big pot to grow to their fullest potential.

fun fact

A tropical bulb

Elephant ears have tuberous roots that are often referred to as bulbs. Unlike common garden bulbs, these ones are not cold hardy so you’ll need over-winter the bulbs inside.

beyond the basics

troubleshooting

  • why is my elephant ear turning yellow?

    Too much sunlight or overwatering. You can cut the dying leaves close to the base of the stem. This should prevent more leaves from yellowing. Then adjust your watering schedule or move it away from direct sunlight.

  • why are my leaves crying?

    Usually due to overwatering. The leaves of an elephant ear are long and heart-shaped, which naturally draws water to the tip of the leaf. If there aren’t other signs of overwatering, like soft stems or yellow leaves, you can likely hold off on watering for a few days.

  • why are my plant’s leaves turning brown?

    It’s a sunburn. Your plant is too close to bright, direct light. Elephant ears tend to thrive in bright, indirect light. Scorched leaves won’t kill your plant, it just doesn’t look pretty.

     

  • Why does my plant’s leaves have spots?

    Fungal leaf blight. If this fungus isn’t caught early, it will cause the whole leaf to collapse and travel to the rest of the plant. To prevent this, make sure you’re using high-quality, well-draining soil.

Lily

aka Lilium

lilies are an exotic and elegant perennial flower that are quite easy to grow. Lilies start as onion-like bulbs and require good soil and lots of sun to flourish.

variations

trumpet lilies, Asiatic lilies, Easter lilies, Oriental lilies

light

full sun

Your lilies will enjoy about 6 – 8 hours of sunlight but be sure to keep their roots cool.

water + feeding

thirsty

Water your lilies freely, especially if you’re not in a climate that gets much rainfall in the summer months.

toxic

yes, the whole plant

The entire plant is toxic to humans and pets. Even the water that fresh cut lilies sit in can make you and your fuzzy friends sick.

location

in the sun

A good rule of thumb is that lilies like their head in the sun and their feet in the shade. To help keep your lily’s roots cool, consider planting with low profile annuals or perennials, or ornamental grasses.

size

medium to large

Lilies can grow between 2 – 8 ft tall!

pro tip

lots at stake

Lilies can grow quite tall. Consider staking your lilies to keep them tall and upright.

fun fact

powerful native plants

Lilies are attractive to many insects because of their bright colours and sweet nectar. They can be pollinated by either the wind or bees!

beyond the basics

  • soil + potting

    Lilies love to have their roots in cool soil, and their heads in the sun. The best soil option to keep your lilies happy is a rich, moist soil. that is also well-draining. Consider adding in just a little bit of organic compost.

  • companion planting

    You can find a wide variety of companion plants from annuals, bulbs to
    other perennials. Consider using annuals such as dill, geraniums, pansies, or new guinea impatiens. Dahlias, daffodils, or irises make great companions when planting other bulbs. Perennials such as peonies, daisies and lavender are excellent companions for lilies.

  • Blooms

    Lilies only bloom once per season. You can remove, or deadhead, faded flowers to keep your plant from wasting energy making new seeds.

  • pest control

    The most common pest issues for lilies are infestations of scarlet lily beetles. These little guys like to hang out on the underside of leaves. The easiest way to get rid of these little pests is to catch them manually by holding a bottle of warm water under the leaves you’re inspecting. The bugs will be startled and drop off into the water waiting below.

troubleshooting

  • what are those oval-shaped spots on my leaves?

    Lily disease. This is a fungal infection that creates oval-shaped dark spots on your lily’s leaves. Make sure you use clean tools before you get started. Then clear out the infected soil and debris and get rid of the infected plant. Be sure to not plant lilies in an infected spot again.

  • why are the tips of my leaves turning brown?

    Could be overwatering, sunburn, or underwatering. If the tip of the leaf is brown and crunchy, this means the soil is likely too dry.

  • why are my buds rotting?

    Likely a fungus. Many fungi (Rhizoctonia, Phytophthora, Pythium, Fusarium, and Cylindrocarpon) attack the bulb and cause the roots to rot. This will also cause the plant to wilt, and eventually die. Be sure to remove the infected plants and check all bulbs carefully before planting.

  • why aren’t my lilies blooming?

    Could be the result of small bulbs or over-crowding in the soil. Planting your lily bulbs too shallow could also lead to your lily not producing big blooms. If you cut away the leaves after a lily has flowered, it may also decrease the likelihood of flowering the following year. Keep in mind, some lilies won’t flower in their first year of planting due to transplant shock.

jade

aka crassula ovata

Jade plants are native to South Africa and are classified as a succulent. Jade plants have oval shaped, fleshy leaves and stems that look like tiny tree trunks.

variations

there are a variation of jade plants available that range from the common green-leaf to more rare variegated varieties. Variegated jade plants can include the tricolour, ET’s Finger or the Hummel’s Sunset variety.

light

bright, indirect.

Jade plants, especially young plants, should get about 6 – 8 hours of light a day.

water + feeding

somewhat thirsty

In spring and summer your jade plant should be watered consistently so that its soil is moist, but not super wet.

toxic

Yes

Jade is toxic to pets.

location

Adaptable

These beautiful plants do well in most indoor settings, but prefer to be close to bright, indirect light. Jade does their best growing in room temperature 18° to 24°C (65° to 75°F).

humidity

a little finnicky

Overwatering and standing water are the most common mistakes made with jade plants. Be sure to monitor your jade for signs of too much moisture.

size

it depends

Jade plants can grow up to 5 ft tall but can stay small if they are rootbound in a small pot.

pro tip

rare flowers

Jade plants don’t regularly flower when grown indoors. To get your jade plant to flower keep it rootbound and in a small pot. Cut back slightly on watering, and you may see a bloom come through.

fun fact

bringers of good luck

Jade is often given as a housewarming gift because it’s thought to bring good luck.

beyond the basics

  • soil + potting

    Succulents thrive in porous, well draining potting mix. These usually have less organic matter than regular indoor potting mix. A mix like Miracle-Gro® Cactus, Palm & Succulent Potting Mix is well-draining and won’t compact. Don’t forget to feed your plants consistently during the feeding season.

  • when to repot

    Repotting a young jade plant every 2 – 3 years will encourage growth. If you want to keep your jade plant small, they enjoy being slightly rootbound and can stay in a small pot to maintain a manageable size. Always repot in the spring.

  • propagation

    Propagating a jade plant is super easy! You can start a whole new jade from just a single leaf or cutting. Remove a leaf or stem cutting from a healthy, mature plant, making sure it’s about 2-3 inches long and has at least 2 leaf pairs. Let the cutting sit in a warm, bright place for several days to develop a little callous. Place the cutting in moist, well-draining soil, keeping it propped upright with rocks. Be sure not to water your jade cutting at this point. After a week or two roots should start to form. Gently water the soil once roots have formed, and allow soil to dry between watering.

  • pest control

    Jade is prone to mealybugs and scale. Mealybugs may hide under the leaves of your plant. During your routine leaf cleaning, inspect the underside. Most pests can be managed by using an insecticidal soap such as Ortho® Bug B Gon® ECO Insecticidal Soap.

fun fact

fast Growers

They’re fast growers and very easy to care for, making them popular houseplants for beginners.

beyond the basics

  • soil + potting

    String of heart plants are a member of the succulent family, so they need a porous, well-draining potting mix that doesn’t retain a lot of moisture because these beauties are prone to root rot. It’s recommended to use a succulent specific potting mix, like Miracle-Gro® Cactus, Palm & Succulent Potting Mix.

  • when to repot

    String of hearts tend to be okay with staying slightly rootbound, so you don’t need to keep a strict schedule when repotting. A good rule of thumb is to repot about every 1 – 2 years. Use a pot that is a few inches bigger than its current pot and has a drainage hole.

  • propagation

    Start by trimming your string of hearts just under a nodule. Place your cutting in moist soil and watch your new plant take root. This process will likely take about a month. Make sure the soil is kept moist during this growing period.

  • pest control

    String of hearts are prone to root rot, so make sure your plant’s soil is drying out between watering. Other pests like aphids or mealybugs can be managed by using an insecticidal soap such as Ortho® Bug B Gon® ECO Insecticidal Soap.

troubleshooting

  • why are there big gaps between my leaves?

    Not enough light. Move your string of hearts to a place where it can sit in ample indirect, bright light.

  • why are my leaves turning mushy and droopy?

    Overwatering or root rot. Root rot is caused by overwatering. The easiest way to tell if it’s root rot or just overwatering is to give it a sniff. If your plant smells bad, it’s root rot. If it smells okay, just hold off on watering it for a little the soil dries out a bit.

  • why are my leaves turning brown?

    Sunburn. It looks like your string of hearts is getting too much sun. These plants enjoy bright, but indirect light. Move your plant away from direct sunlight, but keep in a nice, bright room.

  • why are my plant’s leaves curling?

    Underwatering. Thinning or curling leaves is a clear indicator of underwatering. Give your string of hearts a good soak and your plant should be happily re-hydrated.

fun fact

popular in feng shui

This plant usually sprouts 5 leaves on a stem, and 5 is a very important number in Feng Shui.

beyond the basics

  • soil + potting

    Money Trees need a sandy, peat-moss based soil. Consider adding Miracle-Gro® Sphagnum Peat Moss to your plant’s soil. Don’t forget to use a pot with drainage!

  • when to repot

    Money Trees usually need to be repotted every three years. The best time to repot is during the spring time, to promote growth. While you can cut back on some root growth, be sure not to take off more than 25% of the roots.

  • propagation

    The best way to propagate your Money Tree is through a cutting. Take your 6 inch branch cutting, with several leaf nodes, and allow to root in water. Promptly transfer to a soil mixture with peat moss.

  • pest control

    Money Trees are very attractive to aphids and mealybugs. You can use a gentle insecticide like Ortho® Bug B Gon® ECO Insecticide Ready-to-use to prevent these creepy crawlies from returning.

troubleshooting

  • why are my plant’s leaves drooping or turning yellow?

    Watering issues. If your Money Tree’s leaves are drooping it could be as simple as inconsistent watering. Keep a schedule and check the soil’s moisture level to understand its needs. If the leaves are yellowing, it’s likely due to overwatering. It’s time to water when the top 2 to 4 inches of soil are dry.

  • why is my plant’s trunk spongey and soft?

    Sounds like root rot. This happens when a fungus has attacked your plant’s roots and is a sign that you’ve been overwatering. Root rot can be fatal if it’s not caught early. The best chance you can give your Money Tree for survival is to repot immediately, removing as much old soil as possible.

  • what is this gross, sticky sap?

    Guttation. This it totally normal! If the rest of your Money Tree looks healthy, there’s nothing to worry about. But… if you see little dark bumps on your plant, it could be a pest infestation.

  • why are my plant’s leaves curling?

    Overwatering. Avoid excessive watering and finger test your plant’s soil when you’re about to water. Make sure you’re only watering when the first 2 to 4 inches of soil are dry.

  • why are my plant’s leaves falling?

    Too much sunlight. Too much bright, direct sunlight can cause your Money Tree to drop leaves. Another common cause is if your Money Tree has recently moved to its new home. Dropping a few leaves as your plant adjusts to its new home is totally normal.

sunflowers

aka helianthus anuus l.

Sunflowers are an annual plant with a big, daisy-like flower head. These flowers are heliotropic, meaning they turn their heads to follow the sun across the sky.

variations

There are many variations of sunflowers, but most commonly there are sunflowers with branching stems or single stems. You can also choose from sunflowers that produce pollen, pollen-free or ones that produce edible seeds.

light

full sun

Sunflowers need full sun for optimal growth, about 6 hours of sunlight daily.

water + feeding

not too thirsty

Once established, sunflowers don’t need frequent watering. But they do need deep watering. Overfertilizing can cause stems to break as well. Dillute any fertilizer and avoid the sunflower’s base.

fun fact

herb or flower?

Sunflowers are kind of both. They’re listed as a herb in Encyclopedia Britannica, but also have big flowering heads.

beyond the basics

  • soil + potting

    Sunflowers are not sensitive to the pH level of soil. Use an well-draining soil like Miracle Gro® All Purpose Garden Soil and introduce a water soluble fertilizer about halfway through the summer.

  • companion planting

    Sunflowers pair well with many other plants. Consider pairing with shade-loving plants. Sunflowers can cast some shade on veggies like cucumbers or lettuce. Due to their flexible soil needs, they can be planted alongside plants like bush bean varieties, like lima beans or green beans.

  • blooms

    To encourage side blooms, cut indoor varieties on the main stem just before the flower bud has a chance to open. Cut stems in the early morning vs the afternoon to avoid flower wilting. For cut sunflower bouquets, ensure their container provides enough support for their heads. Change the water daily to keep them fresh.

  • pest control

    Birds and squirrels love to scavenge sunflower seeds. Consider covering the head of the plant with garden fleece or protect them with a tall, wire barrier.

troubleshooting

  • what are these tiny worms?

    They’re probably gray moths. Sunflowers are pretty much pest-free. If you see tiny worms in the head of the sunflower, it’s likely they’re gray moths. Just pick them off the plant.

  • why are my sunflowers losing leave?

    Could be grasshoppers and caterpillars. These little guys enjoy snacking on the leaves of sunflowers. This doesn’t usually damage the plant, but if there are a lot of these pests, they can defoliate your sunflower quickly.

  • what do spotty leaves mean?

    Could be rust, verticillium wilt or mildew. The damaged leaves will fall off as the disease progresses. Control fungi through proper removal and disposal of infected plants and with a general fungicide.

  • why are my sunflower’s leaves wilting?

    Probably white mold. This is a fungus that causes wilting leaves, stem cankers and root rot. Crop rotation can usually prevent this from happening, as well as maintaining proper watering practices.

hollyhocks

aka Alcea rosea

Hollyhocks can easily be started from seeds indoors, and transplanted outdoors. They add drama, colour and height to your garden. These plants are likely to attract some wildlife to your garden such as hummingbirds and butterflies! Hollyhocks can get a little “leggy” and it’s often suggested to plant dense plants in front of them to hide this. Once planted, Hollyhocks can be difficult to move. It’s suggested to plant them in a spot where you won’t have to move them.

variations

Hollyhock ‘Sunshine’, Hollyhock ‘Peaches ‘n’ Dreams, Hollyhock ‘Creme de Cassis’, Hollyhock ‘Blacknight’, Hollyhock ‘Halo Red’, Hollyhock ‘Halo Apricot’, Hollyhock ‘Halo Lavender’, Hollyhock ‘The Bride’, Hollyhock ‘O Hara’, Hollyhock ‘Banana’

varying needs

Full sun to partial shade

water + feeding

not too thirsty

Will tolerate moist conditions if soil is well drained. Water thoroughly during hot, dry weather. Keep water off leaves when watering, to prevent disease problems. The mistake many novice hollyhock growers make is to plant this flower in soil that’s too dry. If you are planting seeds, sow them outside about a week before last frost. If you are planting seedlings out, wait about two to three weeks after last frost. Hollyhock seeds only need to be planted right below the soil, no more than 1/4-inch (.6 cm.) deep

toxic

not really

These flowers are also non-poisonous to dogs or cats, but you need to be careful about the stems and leaves as they may have resin or fiber which may cause some skin allergies.

size

medium-ish

Hollyhock blooms are about four inch double flowers borne on wand-like stems. They have fuzzy leaves, that grow to be about 6-8″ across. A hollyhock plant can grow to be almost 6ft tall!

pro tip

blooms for years

Remove any seed-heads that may form, so hollyhock will continue to bloom for several years. Most plants will live and bloom for several years if stalks are cut off at the base after flowers have faded. They will not be as vigorous as new seedlings. Once established in the garden, hollyhock often grow voluntary from seeds dropped during the summer. These chance seedlings may and should be transplanted elsewhere in the garden.

fun fact

welcome flowers

Hollyhocks symbolize the circle of life, ambition, fertility, and abundance. They have traditionally been planted near the front door of homes to welcome prosperity. Egyptians frequently placed wreaths of hollyhocks with the mummified to help them in their journey to the afterlife.

beyond the basics

  • soil & potting

    Hollyhock will do well in almost any soil but prefers a well-drained soil. The most important factor is good air circulation, so do not crowd plants or plant too close to structures, hedges or other plants.  

  • companion planting

    Hollyhocks make excellent companions for Dahlias, Clematis, Shasta Daisies, Shrub Roses, Baby’s Breath, Black-eyed Susan, or Climbing Roses.  

  • blooms

    Hollyhocks have single or double, cup-shaped flowers with little or no stalk and bloom on tall spikes. Hollyhocks come in a wide variety of colours: blue, pink, purple, red, white, yellow and even black. 

  • pest control

    Rust is a leaf disease to which hollyhocks are especially prone. It is worse on older plants and can be kept in check by replacing plants every couple of years. 

troubleshooting

  • rusty looking leaves?

    Rust is a common problem with hollyhocks and can cause the plants to look ragged. Brown, yellow or orange spots appear as the fungus forms and grows. The damaged leaves will fall off as the disease progresses. Control fungi through proper removal and disposal of infected plants and with a general fungicide. 

  • breaking Stems?

    High winds or torrential rains can damage hollyhocks because of the sheer height of the flowers. The stalks are strong, but can be knocked around by a summer storm. A trellis positioned behind the hollyhocks gives you a place to anchor the plants. Garden twine, looped around the stalk and fastened to the trellis, keeps the hollyhocks in place when strong winds hit the garden. 

  • holes in leaves?

    Japanese beetles love the large leaves of the hollyhock plant and create unsightly holes in the foliage. The hibiscus sawfly looks like an elongated housefly with an orange spot just below the head. The larvae of these pests eat the foliage and can completely destroy the leaves on several plants in a short time. Insecticidal soaps and beetle traps generally aid in ridding the hollyhocks of the pests. 

  • broken stalks?

    Some caterpillars cause hollyhock stems to break and leaves to wilt. Close examination shows small round holes in the stems. Control stalk borers by slitting each affected stem lengthwise, removing the borers, and binding the stems together. Practice clean cultivation and burn all weeds, stems and plant remains likely to harbor over-wintering eggs. 

  • wilting leaves?

    A fungal stem canker attacks hollyhocks at bloom time on rare occasions. Stem lesions are first dark brown and later ash-gray. As these spots girdle the stem the part above wilts, collapses, breaks off and dies. Remove and destroy infected plants or plant parts as soon as you notice them. Disinfect clippers and other tools after using them on cankered plants. Space plants farther apart to minimize splash-borne infection.

Once established in the garden, hollyhock often grow voluntary from seeds dropped during the summer. These chance seedlings may and should be transplanted elsewhere in the garden.

fun fact

welcome flowers

Hollyhocks symbolize the circle of life, ambition, fertility, and abundance. They have traditionally been planted near the front door of homes to welcome prosperity. Egyptians frequently placed wreaths of hollyhocks with the mummified to help them in their journey to the afterlife.

beyond the basics

  • soil & potting

    Hollyhock will do well in almost any soil but prefers a well-drained soil. The most important factor is good air circulation, so do not crowd plants or plant too close to structures, hedges or other plants.  

  • companion planting

    Hollyhocks make excellent companions for Dahlias, Clematis, Shasta Daisies, Shrub Roses, Baby’s Breath, Black-eyed Susan, or Climbing Roses.  

  • blooms

    Hollyhocks have single or double, cup-shaped flowers with little or no stalk and bloom on tall spikes. Hollyhocks come in a wide variety of colours: blue, pink, purple, red, white, yellow and even black. 

  • pest control

    Rust is a leaf disease to which hollyhocks are especially prone. It is worse on older plants and can be kept in check by replacing plants every couple of years. 

troubleshooting

  • rusty looking leaves?

    Rust is a common problem with hollyhocks and can cause the plants to look ragged. Brown, yellow or orange spots appear as the fungus forms and grows. The damaged leaves will fall off as the disease progresses. Control fungi through proper removal and disposal of infected plants and with a general fungicide. 

  • breaking Stems?

    High winds or torrential rains can damage hollyhocks because of the sheer height of the flowers. The stalks are strong, but can be knocked around by a summer storm. A trellis positioned behind the hollyhocks gives you a place to anchor the plants. Garden twine, looped around the stalk and fastened to the trellis, keeps the hollyhocks in place when strong winds hit the garden. 

  • holes in leaves?

    Japanese beetles love the large leaves of the hollyhock plant and create unsightly holes in the foliage. The hibiscus sawfly looks like an elongated housefly with an orange spot just below the head. The larvae of these pests eat the foliage and can completely destroy the leaves on several plants in a short time. Insecticidal soaps and beetle traps generally aid in ridding the hollyhocks of the pests. 

  • broken stalks?

    Some caterpillars cause hollyhock stems to break and leaves to wilt. Close examination shows small round holes in the stems. Control stalk borers by slitting each affected stem lengthwise, removing the borers, and binding the stems together. Practice clean cultivation and burn all weeds, stems and plant remains likely to harbor over-wintering eggs. 

  • wilting leaves?

    A fungal stem canker attacks hollyhocks at bloom time on rare occasions. Stem lesions are first dark brown and later ash-gray. As these spots girdle the stem the part above wilts, collapses, breaks off and dies. Remove and destroy infected plants or plant parts as soon as you notice them. Disinfect clippers and other tools after using them on cankered plants. Space plants farther apart to minimize splash-borne infection.
