Understanding Calla Lily Bulbs

Before diving into the process of storing calla lily bulbs, it’s essential to have a basic understanding of these plant structures. Calla lily bulbs are actually modified underground stems known as rhizomes. They store nutrients and energy that the plant needs to survive and produce flowers.

Calla lily bulbs are made up of a main rhizome from which smaller rhizomes, known as offsets or corms, develop. These offsets are the future bulbs that will grow into mature plants. The size and health of these offsets play a crucial role in the plant’s overall vitality and flowering performance.

It’s important to note that not all calla lily bulbs are the same. There are different varieties of calla lilies, each with its own characteristics and specific storage requirements. These include common calla lilies (Zantedeschia aethiopica), miniature calla lilies (Zantedeschia spp.), and colored calla lilies (Zantedeschia hybrids).

When storing calla lily bulbs, it’s essential to know which variety you are dealing with, as their storage requirements may vary. While the basic principles of storing calla lily bulbs apply to all varieties, understanding the specific needs of your chosen variety will help maximize their chances of survival and future growth.

Additionally, it’s worth noting that calla lilies are not frost-hardy plants. They are native to warmer climates and are grown as summer bulbs in areas with colder winters. This means that in regions with freezing temperatures, calla lilies need to be dug up and stored indoors during the winter to protect them from cold damage.

Now that you have a better understanding of calla lily bulbs and their various varieties, it’s time to move on to the next step: harvesting the bulbs.

Harvesting Calla Lily Bulbs

Harvesting calla lily bulbs is a crucial step in the process of storing them. It involves carefully digging up the bulbs from the ground, ensuring their roots and offsets remain intact. Proper harvesting techniques help minimize damage to the bulbs and increase their chances of survival during the storage period.

Here’s a step-by-step guide to harvesting calla lily bulbs:

1. Wait until the foliage of the calla lilies starts to turn yellow and wither. This is a sign that the plants have entered their dormant phase and are ready to be harvested.
2. Using a garden fork or shovel, gently loosen the soil around the calla lily plants. Be cautious not to damage the bulbs as you dig.
3. Lift the plants out of the ground, making sure to keep the bulbs and their roots intact. You can gently shake off excess soil, but avoid removing too much, as it can contribute to bulb dehydration during storage.
4. Inspect the bulbs for any signs of damage, rot, or disease. Discard any bulbs that appear unhealthy or mushy, as they could spread infections to the stored bulbs.
5. Separate the offsets or corms from the main rhizome, if any are present. These smaller bulbs will serve as future plants, so it’s important to handle them carefully.
6. Trim the foliage of the harvested bulbs, leaving only about an inch of stalk attached. This helps prevent moisture loss and reduces the risk of rotting during storage.

Once you have harvested the calla lily bulbs, it’s time to move on to the next step: cleaning and preparing them for storage.
