Calla lilies are a popular choice for gardeners looking to add a touch of elegance and beauty to their outdoor space. These stunning flowers are known for their trumpet-shaped blooms and come in a variety of colors, making them a versatile addition to any garden. However, to ensure that your calla lilies continue to bloom year after year, it is important to understand the different care requirements for each season. In this comprehensive guide, we will discuss the seasonal care tips for calla lilies, from spring to winter, to help you grow these stunning flowers year-round.
Spring Care Tips for Calla Lilies
Choosing the Right Location
When it comes to growing calla lilies, location is key. These flowers prefer a spot that receives full sun to partial shade, with well-draining soil. It is important to choose a location that is protected from strong winds, as calla lilies have delicate stems that can easily break.
Preparing the Soil
Before planting calla lily bulbs, it is important to prepare the soil. These flowers thrive in rich, well-draining soil with a pH level of 6.0 to 6.5. You can amend the soil with organic matter, such as compost or aged manure, to improve its texture and nutrient content.

Planting Calla Lily Bulbs
Calla lilies are typically planted in the spring, once the soil has warmed up. The bulbs should be planted 2-3 inches deep and 12-18 inches apart. Make sure to plant them with the pointed end facing up and the flat end facing down. Cover the bulbs with soil and water thoroughly.
Watering and Fertilizing
Calla lilies require consistent moisture, but they do not like to sit in water. Water the plants deeply once a week, making sure to soak the soil. You can also add a layer of mulch around the plants to help retain moisture. Fertilize the plants every 2-3 weeks with a balanced fertilizer to promote healthy growth.

Controlling Pests and Diseases
Calla lilies are relatively pest and disease-free, but they can still be susceptible to certain issues. Keep an eye out for pests such as aphids, spider mites, and thrips. If you notice any signs of pests, use an organic insecticide to control the infestation. As for diseases, make sure to remove any dead or diseased foliage to prevent the spread of diseases.
Mulching for Protection
As the weather warms up, it is important to add a layer of mulch around the plants to help retain moisture and suppress weed growth. Mulching also helps to insulate the soil and protect the bulbs from extreme temperatures.
Summer Care Tips for Calla Lilies
Maintaining Adequate Moisture
During the hot summer months, it is important to keep the soil consistently moist to prevent the plants from drying out. Water the plants deeply once a week, and make sure to check the soil moisture levels regularly.
Deadheading and Pruning
To encourage continual blooming, it is important to deadhead the spent flowers. This will also prevent the plants from putting energy into producing seeds. You can also prune back any damaged or dead foliage to keep the plants looking neat and tidy.
Supporting Tall Stems
Some calla lily varieties can grow quite tall, and their stems may need support to prevent them from bending or breaking. You can use stakes or a trellis to support the stems and keep them upright.
Fertilizing and Feeding
During the summer, calla lilies are actively growing and will benefit from regular fertilization. Use a balanced fertilizer every 2-3 weeks to promote healthy growth and blooming.
Protecting from Hot Weather
Calla lilies prefer moderate temperatures and can suffer from heat stress during the summer. If the temperatures are consistently above 85°F, consider providing some shade for the plants to prevent them from wilting or drying out.
Dealing with Pests and Diseases
Summer is the prime time for pests and diseases to attack calla lilies. Keep an eye out for common pests such as aphids, spider mites, and thrips, and use an organic insecticide to control the infestation. As for diseases, make sure to remove any dead or diseased foliage to prevent the spread of diseases.
Fall Care Tips for Calla Lilies
Protecting from Early Frost
As the temperatures start to drop in the fall, it is important to protect your calla lilies from early frost. Cover the plants with a layer of mulch or a frost cloth to insulate them and prevent the bulbs from freezing.
Pruning and Cutting Back Foliage
In the fall, calla lilies will start to go dormant. Once the foliage turns yellow and dies back, you can prune it back to the ground. This will help the plant conserve energy and prepare for winter dormancy.
Preparing for Winter Dormancy
Calla lilies are not cold-hardy and will need to be protected during the winter. If you live in a colder climate, you can dig up the bulbs and store them indoors until spring. If you live in a milder climate, you can leave the bulbs in the ground, but make sure to cover them with a layer of mulch for insulation.
Storing Calla Lily Bulbs
If you choose to dig up the bulbs, make sure to clean off any excess soil and let them dry in a cool, dark place for a few days. Once dry, store them in a paper bag or a mesh bag in a cool, dry place until spring.
Controlling Pests and Diseases
As the plants go dormant, they are less susceptible to pests and diseases. However, it is still important to keep an eye out for any signs of infestation and remove any dead or diseased foliage to prevent the spread of diseases.
Mulching for Winter Protection
Adding a layer of mulch around the plants will help to insulate the bulbs and protect them from freezing temperatures. Make sure to use a thick layer of mulch for maximum protection.
Winter Care Tips for Calla Lilies
Inspecting Stored Bulbs
If you have stored your calla lily bulbs for the winter, make sure to check on them periodically to ensure they are not rotting or drying out. If you notice any issues, make sure to address them immediately.
Maintaining Proper Moisture Levels
If you live in a milder climate and have left your bulbs in the ground, make sure to check the soil moisture levels regularly. Water the plants if the soil is dry to prevent the bulbs from drying out.
Monitoring for Pests and Diseases
Even in the winter, it is important to keep an eye out for pests and diseases. Check the plants regularly for any signs of infestation or disease and take appropriate measures to control them.
Preparing for Spring Planting
In the late winter or early spring, it is time to start preparing for spring planting. If you have stored your bulbs, make sure to bring them out of storage and let them acclimate to room temperature before planting them. If you left the bulbs in the ground, make sure to remove any mulch and prepare the soil for planting.
Protecting from Freezing Temperatures
If you live in a colder climate, make sure to protect your calla lilies from freezing temperatures by covering them with a layer of mulch or a frost cloth. This will help to insulate the bulbs and prevent them from freezing.
Replanting Calla Lily Bulbs in Spring
Once the danger of frost has passed, it is time to replant your calla lily bulbs. Follow the same planting instructions as in the spring and make sure to water the plants thoroughly after planting.
