When it comes to dividing calla lilies, the Royal Horticultural Society suggests doing so in the spring. This is the ideal time for dividing these plants, as it allows them to establish themselves before the heat of summer arrives. Dividing calla lilies is a simple process that can be done by anyone with a little bit of gardening know-how.
To begin, you’ll want to check if your calla lilies need dividing. This can be done by examining the plant and looking for overcrowding or a decrease in flowering. If you notice these signs, it’s time to divide your calla lilies.
The first step in dividing calla lilies is to lift the plant from the ground carefully. Gently dig around the plant, being cautious not to damage the rhizomes. Once the plant is lifted, you can shake off any excess soil to get a clear view of the rhizomes.
Next, you’ll want to inspect the rhizomes for any signs of damage or disease. If you notice any soft or rotting sections, it’s best to discard those portions to prevent the spread of disease. Healthy rhizomes will be firm and have a visible bud or eye.
Now comes the division process. Using a clean and sharp knife or garden shears, carefully cut the rhizomes into sections. Each section should have at least one visible bud or eye. This bud is where the new growth will emerge from, so it’s important to ensure that each section has one.
After dividing the rhizomes, you can prepare them for planting. If you plan to replant immediately, make sure to provide them with well-draining soil and a spot that receives partial shade. Calla lilies prefer moist soil, so be sure to water them thoroughly after planting.
If you’re not ready to replant immediately, you can store the divided rhizomes for a short period. The Royal Horticultural Society suggests overwintering them in pots under cover. This can be done by placing the rhizomes in pots filled with a well-draining potting mix. Store the pots in a cool and dry location, ensuring they are protected from frost.
When spring arrives, you can then plant the stored rhizomes in the ground or in pots, following the same planting instructions as mentioned earlier.
Dividing calla lilies is best done in the spring. The process involves lifting the plant, inspecting the rhizomes, dividing them into sections with visible buds, and replanting in well-draining soil. If needed, the rhizomes can be stored over winter in pots under cover. By following these steps, you can ensure the health and vitality of your calla lilies for years to come.
