Deb Spencer from Waters Edge in Lawrence gave an informative talk at TAWGS September meeting. It was a good reminder for some of us who have had a pond for a long time and very helpful to those who are fairly new at water gardening.
September & October clean-up
1. Stop fertilizing plants about a month before the first anticipated freeze
2. Divide iris, reeds and rushes
3. Trim dying foliage before it falls to the bottom
4. Groom and refresh anacharis pots. Cut off summer's growth and plant in sand or dirt
5. Dredge/vacuum the muck (pond gold) off the bottom of the pond. The muck is great fertilizer for landscape plants
6. Check/adjust the Kh (alkaline) Use baking soda if low
7. Last application of sludge eating bacteria (Aqua One or One Fix)
8. Skim or net falling leaves
