Can You Plant Potted Calla Lilies Outside?

Potted calla lilies are a popular choice for indoor decorations due to their vibrant colors and beautiful shape. However, many people wonder if it is possible to plant potted calla lilies outside. The answer is yes, and in this article, we will discuss everything you need to know about planting calla lilies outdoors.

Choosing the Right Location

Before planting calla lilies outside, you need to choose the right location. Calla lilies prefer a sunny or partially shaded area with well-drained soil. Avoid planting them in low-lying areas where water tends to accumulate, as this can cause the bulbs to rot. If you live in a region with hot summers, it is best to plant calla lilies in an area where they can receive shade during the hottest part of the day.

Preparing the Soil

Once you have selected the location, it is time to prepare the soil for planting. Calla lilies prefer slightly acidic soil with a pH between 6.0 and 6.5. If your soil is too alkaline, you can lower the pH by adding sulfur or other soil amendments. Mix compost or well-rotted manure into the soil to improve its structure and fertility. Calla lilies also require good drainage, so make sure the soil is loose and not compacted.

Planting Calla Lilies

Calla lilies are usually planted in the spring, after the danger of frost has passed. Dig a hole about 4-6 inches deep and place the bulb with the pointed end facing up. Cover the bulb with soil and gently press down to remove any air pockets. Space the bulbs about 12-18 inches apart to allow them room to grow. After planting, water the area thoroughly to settle the soil around the bulbs.

Caring for Calla Lilies

Calla lilies require regular watering, especially during the growing season. Water the plants deeply once or twice a week, depending on the weather conditions. In dry conditions, the plants may require more frequent watering. Mulching the area around the plants can help to retain moisture in the soil and prevent weeds from growing. Fertilize the plants with a balanced fertilizer once a month during the growing season to ensure healthy growth.

Protecting Calla Lilies from Cold Weather

Calla lilies are not frost tolerant and will need protection from cold weather. In regions where the temperature drops below freezing, the bulbs should be dug up in the fall and stored indoors over the winter. In milder climates, you can cover the plants with a frost blanket or other protective covering to prevent the bulbs from freezing. Remove the covering during the day to allow sunlight and air to reach the plants.

In Conclusion

Planting potted calla lilies outside can be an easy and rewarding experience, as long as you follow the proper steps. By choosing the right location, preparing the soil, planting the bulbs, and providing proper care, you can enjoy these beautiful flowers in your outdoor space. Just remember to protect them from cold weather and enjoy your blooming calla lilies all season long!
