Can Potted Calla Lilies Be Planted Outside?

Many people love to grow calla lilies, also known as Zantedeschia, as they are beautiful and come in a variety of colors. However, one question that often arises is whether potted calla lilies can be planted outside. The answer is yes, but there are some important things to consider before doing so. Let's explore further.

Choosing the Right Spot

The first thing to consider when planting potted calla lilies outside is to choose the right spot. Calla lilies prefer a sunny location that receives at least six hours of direct sunlight a day. They also require well-draining soil that is rich in organic matter. It's a good idea to prepare the soil beforehand by working in plenty of compost or well-rotted manure.

Transplanting Potted Calla Lilies

When transplanting potted calla lilies outside, it's important to do so when the weather is warm and the soil is easy to work with. It's best to wait until after the last frost of the season, as calla lilies do not tolerate cold or frost. When transplanting, gently loosen the soil around the roots and carefully remove the plant from its pot. Place the plant in a shallow hole that is slightly larger than the root ball, and backfill with soil.

Caring for Calla Lilies Outdoors

Once planted outside, calla lilies require regular care and maintenance to thrive. They need to be watered deeply but infrequently, as they do not like to be constantly wet. It's important to avoid getting the leaves or flowers wet, as this can lead to rot or disease. Adding mulch around the base of the plant can help retain moisture and suppress weeds. Fertilizing every few weeks with a balanced fertilizer can also help promote healthy growth and blooming.

Protecting Calla Lilies from Pests and Diseases

Like any plant, calla lilies are susceptible to pests and diseases. Some common pests that can affect calla lilies include aphids, slugs, and spider mites. These can be controlled with insecticidal soap or neem oil. Diseases such as root rot, bacterial soft rot, and powdery mildew can be prevented by avoiding overwatering and maintaining good air circulation around the plant. If problems do arise, it's best to treat them as soon as possible to prevent further damage.

Conclusion

In conclusion, potted calla lilies can be planted outside, but it's important to choose the right location, transplant them correctly, and provide regular care and maintenance. With proper care, calla lilies can thrive outdoors and provide beautiful blooms for many years to come.
