Autumn is a second spring when every leaf is a flower.
— Albert Camus
Add Cold Water Beneficial Bacteria to the pond once the temperature drops below 50 degrees F. Dose twice weekly for first two weeks, once per week thereafter.
Below 60 degrees F, transition fish to to cold water fish food. Once temperatures drops to 45 degrees F, stop feeding your fish.
Stop fertilizing your aquatic plants after the first frost.
Decaying leaves and foliage throw your pond out of balance and can harm your fish. Put protective pond netting over your pond before the leaves start to fall.
Trim back hardy marginal aquatic plants to 2" above the water to keep the dead foliage from drooping over into the pond.
Repot your plants. Perform this task in the fall to divide and store non-hardy plants. Many plants such as water iris, and submerged marginal plants can be divided successfully and repotted throughout the mild weather of early fall. However, it is best to repot water lilies and lotus in the spring. If you decide to repot plants during fall, do it as soon as possible. This will allow sufficient time for them to adjust before winter dormancy.
Trim back waterlily leaves and stems to 2-3" above the base of the plant.
Hardy waterlilies in their pots can be dropped into the deepest part of the pond to over-winter. Do not bring them indoors as they need a period of dormancy.
Tropical waterlilies can be over-wintered indoors. Either set the pot in sand or water 50-55 degrees F.
