Guide to Growing African Mallow Shrub in a Pot

The African mallow shrub, also known by its scientific name Malva sylvestris, is a beautiful flowering plant that can add a pop of color to any outdoor space when grown in a pot. With its showy blooms and attractive foliage, this plant is worth adding to your container garden. Growing the African mallow shrub in a pot has several advantages – it allows you to move the plant to capture optimal sunlight, easily bring it indoors over winter, and control the soil and drainage the plant requires. Follow this guide to successfully grow the African mallow shrub in a pot

Choosing the Right Pot

Selecting the proper pot is an important first step to ensure your African mallow shrub thrives. This plant has a deep root system so choose a pot that is at least 12-14 inches deep to accommodate the roots. Make sure the pot has adequate drainage holes in the bottom to prevent waterlogging. A 12-14 inch diameter pot will provide enough room for 1-2 years of growth before requiring repotting. Opt for a pot made from terra cotta or plastic – both provide good durability and drainage.

The Best Soil Mix

African mallow shrubs need a lightweight, well-draining soil. Aim for a mix that retains some moisture but also allows excess water to pass through readily. An ideal potting mix for the African mallow shrub contains:

• 2 parts potting soil
• 1 part compost or manure
• 1 part perlite or coarse sand

This blend will provide nutrients for growth, moisture retention, and sufficient drainage. You can also purchase a ready-made cactus/succulent soil mix. Avoid heavy potting mixes that stay overly wet.

Planting Your African Mallow Shrub

Once you have the right pot and soil mix prepared, follow these simple steps to plant your African mallow shrub:

• Fill the pot with moistened soil mix to about an inch below the rim, firming it down gently with your hands as you go.
• Carefully remove the shrub from its nursery pot, handling the stems gently to avoid damage.
• Make a hole in the potting mix large enough to fit the shrub’s root ball.
• Place the root ball in the hole and fill in around it with more soil mix, firming the soil gently to secure the plant.
• Water thoroughly until water drains from the pot’s bottom. Allow excess water to drain away.

Ideal Growing Conditions

Now that your African mallow shrub is potted, where should you set it up? This sun-loving plant thrives in full sun – aim for at least 6 hours of direct sun daily. An unobstructed south or west-facing location is ideal. If full sun is not possible, the plant can tolerate partial shade, but blooming may be reduced.

Bring your potted shrub indoors any time temps dip below 40 F. It prefers daytime temps of 65-75 F and nights around 60 F while actively growing. Place in a sunny window for winter.

Outdoors during summer, ensure the soil stays consistently moist but not waterlogged. Check moisture levels by inserting your finger 1-2 inches into the soil – if dry, it’s time to water. Provide 1-2 inches of water weekly, allowing the excess to drain fully. Increase frequency during hot, dry periods.

Fertilizing for Healthy Growth

Feed your African mallow shrub with a balanced liquid fertilizer every 2-4 weeks during spring through summer while outdoors. Dilute the fertilizer to half strength before applying according to label directions. This will provide the nutrients needed for vigorous growth and maximum blooms. Cease fertilizing at least 4 weeks before bringing the plant indoors for winter.

Pruning and Deadheading

Regular pruning and deadheading of your African mallow shrub will keep it shapely and floriferous. In early spring, prune back any dead stems or branches using sterilized shears. Remove up to 1/3 of the oldest stems to encourage new growth.

To promote continuous blooming, pinch or snip off spent flowers throughout the season. Deadheading prevents seed production and redirects the plant’s energy into producing more flowers.

Dealing With Pests and Disease

Fortunately, African mallow shrubs are less prone to pests than many flowering plants. With proper care, you’re unlikely to encounter major issues. However, aphids, spider mites, or powdery mildew may sometimes occur. Check plants frequently and address any problems early.

If aphids or mites are present, spray plant leaves thoroughly with a strong stream of water to dislodge them. Follow up by spraying diluted neem oil or insecticidal soap solution. Ensure good air circulation around plants.

Powdery mildew causes a white powdery coating on leaves. Prune out affected parts of the plant. Improve air flow and reduce watering frequency. A fungicide may be needed for severe cases.

Overwintering Your Potted Shrub

There are two approaches to overwintering your African mallow shrub:

• Bring the potted shrub indoors before your first fall frost. Place in a sunny window where temps stay above 60 F. Reduce watering frequency.

• Leave the shrub outdoors in its pot over winter. Stop fertilizing in early fall and trim off dead growth. Surround the pot with mulch to insulate roots.

With the right care, your African mallow shrub will thrive season after season in a container. Just be sure to provide ample sunlight, proper watering and fertilizer, and protection from cold weather. Follow this guide and you’ll be rewarded with a beautiful display of lush, colorful blooms.
