Lotus:Lotus will be hardy if the tuberous rhizomes do not freeze. Plant the containers so that the soil line is below the freezing mark in your pool. This can be from 6 to 18 inches deep, depending on the size of your water feature. Lotuses, like waterlilies, prefer 6 or more hours of sunlight. They die back at the end of the year. Cut them down to a few inches above the rhizome. Be patient with them in the spring as they are late to emerge. They prefer warm weather and will start to grow once the water temperature has risen above 70 degrees. The first new leaves of the lotus float on the surface of the water, while older ones are raised in the air. They have beautiful ornamental seed heads that are used in the florist trade.
Tips and Troubleshooting:
- Make sure your waterlily or lotus gets enough sunlight; at least 4 hours, ideally 6 hours or more.
- Strike a balance between plants and the surface area of the pond; plants should cover approximately 65% of the surface area.
- Remember to fertilize your plants with tablets that you press into the soil around the plant. Do not fertilize directly into the water, as you will change the pH of the water and harm both plants and fish. Fertilize plants once a month. Tropical waterlilies are heavy feeders and should be fertilized generously throughout the growing season.
- Pay attention to depth when you are planting your aquatic plants. Planting too high will cause hardy plants to freeze in the winter; too low will prevent young plants from receiving enough sunlight. Waterlilies prefer to be planted no less than 4 inches and no more than 18 inches below the surface.
- With new plantings, initially place the pot just below the surface and gradually lower as the waterlily grows. Once the plant is established, the pot can remain at the desired depth.
- Remember good maintenance practice: clean off old, yellowing leaves and spent flowers to keep your plants healthy.
