10 tips for growing dazzling tropical water lilies

Here are some tips for getting the most out of your tropical water lilies!

Plant when water temperature is stable

You should plant your tropical water lilies when your water temperatures are at least 70 degrees F. Warmer temperatures means quicker growth but cooler temperatures can send your plant into dormancy or even death.

Don’t plant too deep

Planting in very deep water means slower growth. The water is cooler down at the bottom. Therefore it takes more time for buds and pads to reach the surface. Opt for a water depth of < 18 inches from crown to surface of water.

Plant in a large pot

When you plant in a large pot, tropical water lilies will have large majestic blooms and foliage.

Use a good substrate

Don’t use potting soil. It is lightweight and will float and make a mess. Choose from heavy garden soil, clay, or sand.

Fertilize adequately

Tropical water lilies are heavy feeders. You’ll need to continue providing them with nutrients so you can enjoy blooms. Fertilize every few weeks and don’t place fertilizer too close to the crown of the plant. Be sure not to over apply!

Ensure full sun

Tropical water lilies need ample sunlight in order to go through photosynthesis. Don’t let trees block sunlight and don’t let plants be crowded by one another.

Maintain for more

Instead of letting old foliage and blooms rot away–remove them on a weekly basis. You will be rewarded with more.

Be proactive with pests

Reactive is a response. Take care of tropical water lily pests beforehand. For example: weekly spraying of BT will prevent pad damage by the China Mark moth aka sandwich men.

Don’t allow splashing

Constant turbulence from fountains can be a disaster for the pads. They will yellow or develop fungi and rot away.

Protect plants from aggressive fish

Fish that dig will make a mess in your pond and stress your tropical water lily. Place river rock around the crown of the plant, leaving a small gap between the crown and the surrounding rocks. Don’t use pea gravel unless your fish are small–otherwise they will toss them around.
