The truth about plants for shady ponds
Many experts tell us that you cannot grow many plants for shady ponds. That the choice is very limited and that you should not place a pond in the shade, if you wish to have a successful water garden. They seem to overlook the fact that there are shade tolerant water lilies and waterlily-like plants as well as an impressive range of plants for shady ponds.
Water lilies and most pond plants require at least 6-8 hours of direct sun to flower and flourish.
Sometimes there is no choice but to place your pond in an area of little or no sunshine. Or perhaps the pond was placed in the shade before the importance of the sun was realised. For those situations, our plant choices may appear to be limited but by carefully selecting plants for shady ponds, beautiful water gardens can still be obtained.
The Pro's and Con's of shady ponds….solutions…
Trees can provide shade for a pond, but also create problems. Leaves and twigs that fall into the pond and need to be removed. Excess leaf matter slowly decomposes underwater and creates gases that may be toxic to some aquatic life. Therefore trees can create more work.
A solution to this problem can be through the use of pond skimmers that collect the water off the pond surface, much like a swimming pool skimmer. The leaves that fall into the pond drift into the pond skimmer and are captured in the mesh filter. The water passes through and is pumped to another part of the pond. All that you really need to do is empty out the skimmer as required to collect most of the leaves.
Shady ponds are often cooler. Fish come up to the surface and tend to be more visible. Shallow ponds in full sun, tend to heat up and fish hide where it is cooler closer at the bottom, so they are harder to see.
We recommend that you reduce the number of plants for shady ponds, in order to reduce the competition for the little sunlight that there may be. Although the number of plants for shady ponds is reduced, you can increase the range of plants around the outside of your pond.
There are several varieties of shade tolerant water lilies, marginal, and floating plants that will do well in partial shade and some will tolerate as little as 3 – 4 hours of direct sun. For some water lilies, the foliage will still grow and you may have reduced flowering, but that should not stop you from enjoying an occasional flower. Some shade tolerant water lilies even have mottled foliage that will give you some variety in your floating pads.
