Another job in the garden! There’s always something to do and very often in summer months, ponds get overlooked until they need a serious tidy up. They are a lovely addition to any garden and provide a rich habitat for all sorts of wildlife but without care can become an eyesore. At this time of year try to spend a regular few minutes each week removing visible pond weeds and algae plus weeds around the pond too If your pond is green and a bit smelly it may be the ratio of pond plants to water is wrong, ideally they should be evenly matched. It could also be caused by too much sunshine so plant more shading plants as marginals. Keeping an eye on oxygenators is important as well as they can take over in which case they need to be cut back.
In hot and windy weather water levels can drop and the pond may need topping up but ideally, this should be with water from your water butt as tap water is rich in nutrients and encourages algae.
If we have very hot weather with humid nights you may want to gently spray the surface with a hose to improve oxygen levels.
Regular cleaning and maintenance will ensure your pond remains visibly pleasing for you and healthy for fish and other wildlife.
