How to Grow Calla Lily Plants

Planting Time: Calla lilies are generally planted in the springtime. This planting period gives them enough time to grow moderately fast and produce their beautiful flowers by early-to-mid-summer, continuing to bloom until early fall.
Planting Method: These plants grow from rhizomes. Rhizomes are the underground parts of the plant that resemble bulbs. It’s best to plant them in loose, well-drained soil.
Sunlight Needs: Calla lilies love sunlight. They prefer to be located in full sun or partial shade in warmer climates. Prolonged exposure to direct sunlight, however, can be harmful, especially when they’re kept indoors.
Water Requirements: Watering your Calla lilies is simple. Just ensure you water them when half of the soil volume is dry. Water until the liquid flows through the drainage hole at the bottom of the pot and discard any accumulated water.
Fertilizer: Feed your calla lilies regularly for best results. Remember, the exact frequency and type of fertilizer can vary based on your specific growing conditions.

Where to Grow Calla Lily

Outdoor Planting: Calla lilies can be planted in beds and borders for a lovely display in your yard. They are considered tender perennials, flourishing in warmer climates and USDA zones 8 to 10. However, in cooler climates, they can be grown as annuals for a stunning late-season display.
Indoor Planting: Calla lilies make stunning houseplants, especially when grown in containers. They can be grown near sunny windows where they receive plenty of indirect sunlight. They also thrive under grow lights if natural light is insufficient.
Potted Planting: You can grow calla lilies in containers too. Choose a deep container that’s about 12 inches in diameter. This method offers flexibility as you can place the pots outdoors during warmer months and bring them indoors during harsh winters.
Geographical Considerations: Originally from South Africa, Calla lilies are adaptable and can be grown in various regions. However, they can sometimes be invasive, specifically in regions like Australia and California. Be aware of this potential when planting in these areas.

Bear in mind that Calla lilies, while incredibly beautiful, are toxic to humans and pets. All parts of the plant contain toxins.

So, while they make a lovely addition to your home or garden, be cautious if you have young children or pets that may be tempted to nibble on the plants.

How to Prune Calla Lily Plants

Pruning Calla Lily plants isn’t a complicated task but it does require some patience and care.

Know the right time: The best time to prune Calla Lily is at the end of their growing season. This is usually in the late fall or early winter after the plant has stopped flowering.
Identify the foliage to prune: You’ll want to focus on the yellow or brown leaves that appear wilted. These are the leaves that are dying off and should be pruned.
Use the right tools: Make sure to use sharp, clean shears or scissors to avoid damaging the plant or spreading disease.
Prune carefully: Cut the dying foliage at the base of the stem, as close to the soil as possible.
Clean up: Collect the cut leaves and dispose of them properly to prevent any possible spread of disease.

Propagating Calla Lily is a great way to multiply these beautiful flowers in your garden. Here are some steps to guide you through this process.

Choose the right time: The best time to propagate Calla Lily is during their dormant season, typically in the fall.
Preparation: Before you start, make sure you have a pot with well-draining soil and a healthy Calla Lily plant.
Identify the rhizomes: These are the thick, tuberous roots that grow underneath the soil. You’ll want to gently dig up the plant and locate these.
Cut the rhizomes: Using a sharp knife, divide the rhizomes into pieces, ensuring each piece has at least one ‘eye’ or growth point.
Planting: Plant the divided rhizomes into the prepared pot, ensuring the ‘eyes’ are facing upwards.
Care: Water the newly planted rhizomes moderately and keep them in a place where they will receive plenty of indirect sunlight.

Pests and Diseases

While Calla Lily plants are quite hardy, they can still fall prey to various pests and diseases.

Pests: Some common pests that attack Calla Lily include aphids, spider mites, and thrips. If you notice small, discolored spots on your plants or see small bugs crawling around, you may have a pest problem.
Diseases: Calla Lily are susceptible to various diseases, including bacterial soft rot, root rot, and various fungal infections. Symptoms include wilting, yellowing leaves, and a foul smell.
Management: Regular inspections and early intervention can help manage these issues. For pests, you may use insecticidal soap or introduce beneficial insects like ladybugs. For diseases, removing the infected parts of the plant and improving drainage and air circulation can help.

The steps outlined in these guidelines will help you to maintain a healthy, vibrant Calla Lily plant.

Whether you’re pruning, propagating, or managing pests and diseases, remember to be patient and consistent. These plants are worth the effort!

FAQs

What type of soil is best for Calla Lily?

Calla Lilies prefer well-draining soil that is rich in organic matter. They grow best in soil that is moist but not waterlogged. The soil should be loose and well-aerated to allow for proper root growth. You can use a good quality potting mix or create your own by mixing equal parts of peat moss, perlite, and vermiculite. Adding compost or aged manure to the soil can also help improve its fertility and texture.

How often should I water my Calla Lily?

Calla Lilies require regular watering, especially during the growing season. Water the plants deeply, allowing the soil to dry out slightly between waterings. Aim to keep the soil consistently moist, but not overly saturated. Overwatering can lead to root rot and other issues. During the dormant period, which occurs after flowering has ceased, you should refrain from watering as much to allow the plant to die back.

Can Calla Lily be grown indoors?

Yes, Calla Lilies can be grown indoors as long as they receive adequate sunlight and proper care. Place the plant in a location that receives bright, indirect sunlight or direct sunlight for a few hours each day. Water the plant sparingly, allowing the soil to dry out between waterings. Fertilize the plant once a month during the growing season with a balanced fertilizer. Repot the plant every two years to ensure proper growth and development.

When should I plant Calla Lily?

Calla Lilies are typically planted in the spring. They grow moderately fast, often producing flowers by early-to-mid-summer and blooming throughout the season until early fall. Plant the rhizomes in well-draining soil that is rich in organic matter. Water sparingly at first, and then increase watering once the plants have a few leaves. Calla Lilies prefer to be located in full sun or partial shade in warmer climates.

Do Calla Lilies require fertilization?

Calla Lilies have low nutrient requirements, but they can benefit from occasional fertilization during the growing season. Use a balanced, water-soluble fertilizer specifically formulated for Calla Lilies or other flowering plants. Follow the instructions on the fertilizer packaging for the appropriate dosage and frequency. It is important not to over-fertilize, as this can lead to excessive growth and damage to the plant. Fertilize sparingly, typically once every 2-4 weeks during the active growing season, and reduce or stop fertilization during the dormant period.

How do I plant Calla Lily?

Start by preparing the soil by loosening it and removing any weeds or debris. Plant the rhizomes 2-3 inches deep and 12-18 inches apart, depending on the variety. Cover the rhizomes with soil and water thoroughly after planting to settle the soil and provide moisture to the roots. Mulching around the base of the plants with a layer of organic mulch, such as straw or wood chips, can help conserve moisture and suppress weed growth.

How much sunlight does Calla Lily need?

Calla Lilies require full sun to partial shade. They should be planted in a location that receives at least 4-6 hours of direct sunlight per day. Adequate sunlight is essential for the plant’s growth, flower production, and overall health. If your garden doesn’t receive enough sunlight, you can consider growing Calla Lilies in containers and placing them in a sunny spot or using artificial grow lights to supplement the light.

Are there different varieties of Calla Lily?

Yes, there are numerous varieties of Calla Lilies available, each with its own unique characteristics, flower shapes, colors, and bloom times. Some popular Calla Lily varieties include the classic white, pink, yellow, and red. Each variety has its own unique growing requirements and flower forms. Choose a variety that suits your preferences and growing conditions.

Are there any pests or diseases that affect Calla Lily?

Calla Lilies are generally pest and disease-free, but they can be affected by common issues such as spider mites, aphids, and fungal diseases. Regularly inspect the plants for any signs of infestation, such as webbing or distorted growth, and take appropriate measures, such as using organic insecticides or fungicides, if necessary. Proper watering practices and good air circulation can help prevent fungal diseases.

How do I care for Calla Lily after blooming?

After the Calla Lily has finished blooming, you can cut back the spent flowers and stems to encourage new growth and potentially more blooms. Allow the foliage to die back naturally, and then cut it back to the soil level. Reduce watering during the dormant period to allow the plant to rest. If you are growing Calla Lilies in containers, you can repot the plant every two years to ensure proper growth and development.
