Care of calla lilies

Care of calla lilies can be easy if you follow some simple guidelines. The flowering time of a calla lily varies from one day to the next, so it’s important to know when to harvest them.

You can do this at various times during the day but be sure to take note of the flower’s condition before you pull it off the plant.

Callas should be harvested when they are fully open, with stamens still visible. They require lots of light and cool weather.

A temperature of 65 to 55 degrees Fahrenheit is ideal for calla lilies. Most people keep their homes much warmer than this, so they can easily go into a dormant phase. To prevent this, mulch the soil around the bulb to keep it cool.

Remember that calla lilies can go into a dormant stage for a couple of months.

However, it doesn’t necessarily mean that the bulbs should be dug up and brought inside during this time.

Although calla lilies are perennials, they need regular watering, fertilizer, and a dormant period after flowering.

The flowers are not a good idea to bring indoors during the winter, and you should keep them in a dark place during the cold season.

You can also plant them in the ground after the danger of frost has passed. In either case, you should wait until the foliage begins to yellow before fertilizing.

Watering calla lilies is necessary for maintaining growth and giving them essential nutrients. However, be sure not to overwater hybrid calla lilies.

Diseases that can affect calla lilies

Calla lilies are susceptible to a number of diseases, including crown rot, pythium rot, gray mold, and leaf spots. Here are some of the more common ailments.

You can prevent these diseases from affecting your plants by following the steps outlined below.

To avoid any harmful effects, treat your calla lilies early. You can prevent many of them by following simple guidelines, such as avoiding overwatering.

Bacteria and viruses may attack the lower leaves of your callas and cause stem rot. This type of disease can spread to the roots.

Ring mosaic virus is another common disease that can reduce the beauty of callas and their ability to flower.

Pesticides can be used to prevent the spread of this disease. Pesticides can also be used to prevent gray mold and rhizome rot.

Excessive fertilization can damage calla lilies. In addition to causing discoloration, too much nitrogen can kill the entire plant. To avoid these issues, keep your callas in a well-draining soil. If your callas are subject to a lot of debris, such as fallen leaves and branches, they could harbor a number of pests.

In addition to these pests, weeds in proximity to calla lilies may act as host plants for aphids and thrips, which can transmit viruses.

Another major issue that can cause your calla lilies to curl is a lack of sunlight. Calla lilies naturally prefer sunlight.

They will thrive in partial shade, but lack of sunlight can cause them to wilt. If you notice curling leaves, you should repot them.

Make sure to provide them with several hours of sunlight every day. It is important to keep the soil moist for several days after repotting.
