How to plant water lilies?

Plant the waterlilies in the spring – from late April to May. Make sure to plant lilies when the weather is a bit warmer. Even if hardy lilies can tolerate colder temperature, it is important to still avoid planting them when there’s a risk of frost.

1. Prepare your containers. Make sure the containers meet the ideal depth and width. Select a container that doesn’t have a drainage hole but if the containers have drainage holes, use a burlap to cover it to keep the soil in the container.

2. Fill the containers with a heavy clay loom soil. Do not use floppy plotting soil, it won’t be able to hold water and will float out of the container. Only use soil that is specifically for aquatic plants. Add fertilizers to prepare the soil for planting. The amount of fertilizers needed depends on the specific product you are using. Read the instructions properly.

3. Plant the waterlilies tubers in the container. Make sure to place them on the side of the container with the tip pointing upward at 45 degrees angle and to the center of the container. Add more soil and cover the top with small rocks or pea gravel to keep the soil from floating. Make sure to rinse the pea gravel before adding to make sure it’s free from any pest or insects. Don’t add too much gravel around the base of the plants to avoid stressing the new plants and to give enough space for them to grow.

4. Water the plants well and then place the container in a pond or aquatic planter. Make sure the leaves or crown is not submerge in the water and floating instead. If the pond is too deep, put planting ledges or stack bricks under the container to ensure the leaves will float. This will ensure the growth of the lilies.

1. Lower the container gradually as the lilies grow as well. Make sure the crowns are always partially covered by water.

2. Remove dead leaves and old flowers before they rot. Flowers only last up to 4 days and they should be trimmed when they wither. Leaving dead leaves and old flowers might infect the entire plant and will help keep the water clean in the pond. This will also encourage growth for new flowers.

3. Add slow-release fertilizers every month. To add fertilizers, simply lift the container out of the water and use your hands to insert fertilizer pellets or tablets to the soil. Smooth out the gravel and put back the container into the pond or to your aquatic planter.

4. As the lilies grow, the rhizomes or the root ball, crowd the container. Divide them every couple of years and plant the new tubers in separate containers. If you have a big pond, this will give you more water lilies to admire.
