Plants and Water Features
The main problems with outdoor water features such as drilled stone ornaments are the build up of silt in the reservoir and algae build up. The cleaning process is as per ponds, draining down and manual removal of silt and leaves and cleaning of pumps. Algae build up on the surface of the ornament is usually best removed with a pressure washer.
Plants require trimming of old foliage in late autumn and early winter, large rooted plants like lilies can outgrow their pots and can be divided and repotted. Again, any planting work can be tied in with cleaning/ maintenance visits if required.
