Role of water garden plants in Carlisle, Mechanicsburg, Harrisburg & Hershey PA
The flowers of tropical water lilies sit above the water and come in the typical whites, yellows, pinks, and reds. Unique to tropical water lilies are the blue shades - light blue to deep purple. Flowers are also more often fragrant and there are varieties available that bloom at night.
Although tropical lilies are only hardy to zones 10 and 11, they can be planted in colder zones when the water temperature is consistently above 70? F and treated as annuals or over-wintered, if given proper care. In Carlisle PA we are in zone 6 - 7.
To Pot or Not?
Go natural when planting your water lilies - hide those pots! Planting pockets help you do this. Hopefully these have been excavated into your pond, if not, you can create them with rocks right on the liner. Place the potted lily into the pocket and cover with rocks to hide the pots.
Fertilizing water lilies is necessary to encourage a greater number of larger flowers. Time-released, granular fertilizer, mixed into the soil at the bottom of the pot or plant pocket is a great way to fertilize lilies at the time of planting. Any other time, however, it would be messy and inconvenient. That's when lily fertilizer tablets work great.
