love it

They love high humidity.

size

medium

They can grow between 2 – 6 feet.

pro tip

dry as a bone?

Keep the soil pretty dry throughout the winter, giving it a little water at every 2 weeks.

fun fact

need light and dark

The short days and long nights of fall and winter are perfect for poinsettia. It’s actually what causes them to bloom.

beyond the basics

  • soil + potting

    Your Alocasia needs a well-draining potting mix. The Miracle-Gro® Indoor Potting Mix contains coconut coir and perlite to hold onto and release moisture as your plant needs it. If you find that your plant is wanting a little extra, you can add in some Miracle-Gro® Cactus, Palm & Succulent Potting Mix. Adding this succulent mix helps keep your soil light and airy.

  • when to repot

    Like most indoor tropical plants, the best time to repot is in the spring or summer, when your plant is strong. Your alocasia will likely want to be repotted every 18 – 24 months. When you’re selecting its new pot, choose one that is about 2 – 4” bigger than its current one.

  • propagation

    To propagate your alocasia, use the division method. Remove the plant from its pot and separate a small clump of roots from the main rootball. Replant the small clump into a new pot with fresh soil. Make sure it’s buried at the same depth as the original plant.

  • pest control

    Your alocasia may be more prone to spidermites than your other indoor plants. To help prevent those nasty mites from appearing, make sure your plant doesn’t dry out too much over the winter. If you see spidermites on your alocasia, you can use Ortho® Bug B Gon® ECO Insecticidal Soap Ready-To-Use. Spray this insecticidal soap on your plant to eliminate those pesky mites.

     

troubleshooting

  • Why are my leaves dying?

    Not enough humidity or dry soil. Your alocasia could probably use a good watering. If you’re already on a watering schedule and you’re still noticing dying leaves, consider increasing the humidity in the room.

     

  • Why are my leaves turning yellow?

    Overwatering. Allow the soil to dry out a bit before watering your plant again. For future waterings, make sure the soil is about 25-50% dry before watering.

  • Why are my leaves turning brown?

    Probably a sunburn. If your alocasia is too close to bright, direct light then it’s time to move it away. Your alocasia wants to be in bright but indirect light, so find a spot that isn’t right in front of a window. If your lighting is okay, then it could be fertilizer burn. To fix this, drain any accumulated fertilizer from the potting mix, or repot with fresh soil.

  • What are these rusty spots on my leaves?

    Fungal infection. Poor light and warm, humid conditions can be responsible for fungus. To prevent this make sure the leaves stay as dry as possible. Instead of overhead watering, opt for bottom watering or watering straws instead. Be sure to remove any dead, decaying or diseased plant matter from your alocasia’s pot.

indirect

Need about 6 hours of indirect sunlight daily

water + feeding

not too thirsty

Water in moderation when soil is dry to the touch

toxic

kind of

They’re not toxic to humans or pets. However, the white, milky sap can irritate some people’s skin and can cause an upset stomach.

location

flexible

They’ll be happy in a semi-shaded or sunny area

humidity

love it

Poinsettia enjoy 50 – 75% humidity, so boost up the moisture

size

small friends

Potted poinsettia will remain small at 8 – 12 inches

pro tip

dry soil is ok

Allow the soil to dry out between watering, especially in the spring.

fun fact

need light and dark

The short days and long nights of fall and winter are perfect for poinsettia. It’s actually what causes them to bloom.

beyond the basics

  • soil + potting

    Whether poinsettia is growing indoors or outdoors, they prefer a loose, well-draining potting mix. Consider using Miracle-Gro® Moisture Control® Potting Mix. You can also add Perlite and Peat Moss to your soil for some added nutrients.

  • when to repot

    As your poinsettia grows, so does its roots. To avoid your poinsettia getting root-bound, repot it in the spring. It’s generally recommended that by mid-May, your poinsettia will be ready to repot. Choose a pot that is about 2 inches wider and deeper than its current pot. And of course, refresh the soil when you repot.

  • propagation

    The most common way to propagate poinsettia is by taking a cutting. Propagating from cuttings ensures a clone of the parent plant. No surprises! To start, wait until the spring to take your cutting. Using sharp scissors or pruners, cut a 3 – 4 inch stem from the parent plant. Then cut off a few of the lower leaves to promote root growth from the cut edge. Be sure to leave at least 3 leaves at the top of the cutting. Transplant your cutting to a small container with well-draining potting mix such as using Miracle-Gro® Seed Starting Potting Mix. Keep your cutting in a bright, humid area, and mist the leaves regularly to stimulate growth.

  • pest control

    Whiteflies are the most common pests for poinsettias. Do regular checks under the leaves of your poinsettia and keep an eye out for clumps of greenish eggs. Use a gentle insecticide like Ortho® Bug B Gon® ECO Insecticide Ready-to-Use to easily and quickly get rid of white flies.

troubleshooting

  • Why are my cuttings collapsing?

    Bacterial rot. This causes the base or stem of the cuttings to become mushy and eventually collapse. You may also notice a smell surrounding your plant, which is also caused by this bacterial infection. You may be able to mitigate this by proper watering and misting practices. It’s best to cut off misting and watering for a while once you notice the stems are a little soft.

  • Why are my poinsettia’s leaves turning black?

    Temperature fluctuations. Sudden temperature fluctuations will shock these tropical plants. To keep your poinsettia happy, make sure it’s in a bright space that can also receive a few hours of shade or darkness. Be sure to keep your plant away from radiators, fireplaces and space heaters too.

  • Why is my poinsettia so pale all of a sudden?

    Could be spider mites. These little pests feed off the plant’s sap, causing the leaves to turn pale and sometimes develop little red spots. If you catch spider mites early enough, you may be able to salvage your plant. Use a gentle insecticide like Ortho® Bug B Gon® ECO Insecticide Ready-to-Use to gently take care of this problem. A recovering poinsettia will perk up and brighten up within a week or two.

  • Why are my poinsettia leaves drooping and yellow?

    Over- or underwatering. Both over and under-watering your poinsettia will cause its leaves to droop or look wilted. If you’re over-watering your plant, be sure to let its soil dry out a bit. Discard any excess water at the bottom of its pot to prevent it from sitting water and developing root rot. If you’re underwatering, consider boosting your watering routine with Miracle-Gro Indoor Plant Food for the next two watering cycles. You can also start misting the leaves of your poinsettia to increase its water in-take. But don’t overdo it, let the soil dry out a bit between watering.

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’

light

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.

    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.

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’

light

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.
