Everything about mallow flower : How to Plant & care for them

Mallow Care

In the right conditions, mallow is extremely easy to grow and maintain. It is a short-lived species that will fade after three or four years. However, the plant self-seeds readily producing new volunteers identical to the mother plant. The dense, bushy foliage is attractive and adds interest to the garden from early spring right through to the fall. For gardeners that love to attract pollinators to the garden, the mallow is an ideal choice to attract bees and butterflies. For many gardeners, virtually no maintenance will be needed. At most, you may need to stake up flowers to prevent toppling from strong winds or apply a fungicidal powder if disfiguring fungal leaf spots bother you.

• Light

In temperate regions, it’s best to position your mallow in a full sun position. If you live somewhere that experiences intense afternoon sun, a partial shade location would likely be better to prevent leaf discoloration and promote better flowering.

• Soil

Mallow can tolerate a wide variety of well-drained soil types. Its preference is moist loamy or sandy soil that is reasonably fertile. But if the soil is overly rich, it can result in the flower stems sagging.

• Water

This plant, once established, is moderately drought-tolerant. It prefers to be kept consistently moist but won’t survive in waterlogged soils.

• Temperature and Humidity

Mallow enjoys temperate climates of zones 4 to 7 and can handle light frosts during the transition seasons. Excessively hot and dry conditions result in the foliage turning from green to a scorched yellow. High humidity climates often see problems with leaf fungal diseases.

• Fertilizer

Your mallow will accept a monthly application of a balanced fertilizer during its flowering period, but it requires almost no feeding if the soil is moderately fertile. Avoid excessive feeding, as this can make the plant excessively leggy and cause it to sag.

Pruning

Pruning of your mallow is recommended to prevent this readily self-seeding plant from taking over your garden. For this reason, as soon as the blooms are spent, they should be deadheaded. This can sometimes also encourage a second flush of blooms in the late summer. Cutting the entire plant back down to the basal foliage is also an option after the bloom period concludes in the late summer or fall. Be aware that some self-seeding might occur using this method. If you want to keep your mallow neat and compact, it’s worth pinching back new growth tips as they first appear in the spring. Be wary of adding mallow clippings to a compost bin, as the seeds may persist and cause unwelcome volunteers when the mulch is used in the garden.

Propagating Mallow

New mallow plants can be easily grown from healthy basal cuttings ( cuttings taken from around the base of the plant ) in the spring or early summer. However, this plant is so easy to grow from seeds that collecting seeds for replanting is a much more common method of propagation. If you do want to try vegetative propagation, here’s how to do it :

1. In late spring or early summer, use a sharp, clean pruner to clip a section of root crown around the base of the plant just as it’s beginning to put out new growth. It’s best to clean the pruner between each cut to ensure you’re not transmitting any fungal diseases. The cutting should contain both a section of the root crown as well as emerging green growth.
2. Plant the basal cutting into a container filled with ordinary potting soil, and moisten it thoroughly. Applying a rooting hormone to the cutting before planting is optional.
3. Continue growing the planted cutting outdoors in its pot until active new stem growth is evident—this usually takes several weeks.
4. At this point, the new specimen can be transplanted into the garden.

How to Grow Mallow From Seed

Mallows are extremely easy to grow from seeds purchased from online retailers specializing in wildflowers or collected from the dried seed pods on existing plants. There is usually no need to start seeds indoors. The normal outdoor planting time is spring as soon as the soil can be worked, but even seeds planted in fall will usually sprout in the spring. Plant the seeds shallow, barely covering them with soil. Germination and sprouting are usually evident within two weeks.

Overwintering

When cold weather kills the foliage, cut the stalks down to the basal leaves. ( You can leave a few plants standing if you wish for them to self-seed in the garden. ) In borderline climate zones, cover the plants with a layer of mulch or leaves for the winter to protect the roots. This mulch layer should be removed promptly in the spring to prevent root rot.

Common Pests & Plant Diseases

There are no life-threatening pests and diseases for this plant, though Japanese beetles will often feed on them in regions where this insect is prevalent. In hot, humid climates, the plants can be susceptible to several fungal leaf diseases. While unattractive, these diseases are rarely fatal; if necessary, they can be treated with fungicide powders or sprays.

How to Get Mallow to Bloom

Mallow rarely needs help to bloom, but deadheading spent flowers will encourage additional blooms. A plant that fails to flower at all is probably not getting enough sunlight.

Common Problems With Mallow

Mallow is typically easy to grow, and the problems that do occur are cosmetic rather than life-threatening. Some common issues include:

Excessive Self-Seeding

Their ability to readily self-seed can prove to be an annoyance for some gardeners as volunteer seedlings can be tricky to remove once they are established. Careful deadheading and cutting back will be required during the summer if you want to prevent spreading.

Toppling Plants

With its tall, upright form, this plant may require staking in exposed windy locations or if growing in rich soils that cause legginess. Selecting a sheltered position out of strong winds is recommended.
