As mentioned above, Calla lilies produce seed pods after flowering and the color of these seed pods are tan. According to a gardening expert named Walter Reeves, each of them has a minimum of one or two seeds. Several months are the time needed for the Calla lily pods to mature, that’s why patience is needed. After the pods dry on the plant, you should gather the pods. Then, get rid of the seeds from the pod and place them in an airtight container in an area with cool temperatures until the spring comes.

Apparently, Calla lily seeds need a three month dormancy period so you are recommended to sow the seeds that have been collected in fall in spring to get the best germination rates, as per Burpee. It is best for you to transplant the seedlings of this plant outside in early summer. They are best to be placed at the same depth they were growing at in their pots. It is also needed for you to place them in a full sun and well drained bed. As one of the outdoor plants, Calla lilies need to be watered 1 to 2 inches of water a week to prevent the soil from drying out completely.

There are a few steps to follow to grow Calla lily from seeds, as follows:

  1. The first thing that you need to do is to soften the Calla lily seeds. In order to do this, firstly, fill a bowl with warm tap water. Then, submerge the seeds in the water and leave them all night long or for at least 8 hours long. The time is needed to soften the outer seed coat and speed germination.
  2. Then, prepare the pot and sow the seeds. To do this, you will have to fill 3 inch seedling pots by using a standard potting mixture and set the pots in a drip tray. Then, sow the seeds on the surface of the soil and then press them into the soil to cover most areas of the top.
  3. In the next step, give the initial water. Put about one inch of the water into the drip tray and let the soil soak up the water through the bottom drainage holes in the pots. When you feel like the soil is moist, it is time for you to pour out the rest of the water. This thing usually takes up to an hour long.
  4. It is important to maintain the proper moisture and light germination. The pot has to be covered with a clear plastic bag to keep the moisture and the air of the soil as the seed germinates. The pot should be set in a 70 to 75 degrees Fahrenheit location as it is the best place to get the best bright and indirect light. For your information, the light is important to make the seeds germinate.
  5. After germination, get rid of the bag. Monitoring the soil moisture and water are a must when the soil starts to dry before the process of germination. Once the seeds sprout, it is time for you to get rid of the bag once. usually it will take one to three months.
  6. Then, give seedlings with light and water. After the seeds sprout, the pot has to be moved to a place that gets 66 to 8 hours of direct sunlight. When the surface of the soil dries, remember to water the Calla lily seedlings.
  7. Lastly, transplant the seedling. After the seedling produces the second set of the true leaves, the next thing that you need to do is to transplant the plant into a 6 inch pot. You are encouraged to plant it at the same depth as when it was growing before. Please select an acidic potting mix like the one that is formulated for azaleas.
