Readying your water garden for winter
means pond cleaning, plant and fish care, and pump and filter maintenance. Your Growise
Center staff can offer helpful tips for a healthy pond.
THE POND
Remove leaves from pond with a leaf skimmer.
Clean base of pond to loosen muck. Follow with a liquid to clear
up water. Or use a water garden vacuum to finish clean-up. Cover pond with a taut, strong
mesh net to keep out leaves and twigs. Visit your Growise Center for pond clean-up tools
and products.
PLANTS
Hardy Water Lilies
Prune and lower the lily to deepest part of pond. If sufficient
depth of water can be maintained to prevent root freeze, plant can remain in pond. If
brought indoors, submerge plant in tub or barrel in heated basement or garage. Change
water monthly.
Tropical Water Lilies
After frost, cut back to couple inches above container. Wrap
container in damp newspaper in plastic bag; store at 65 degrees F. Open bag weekly for 24
hours.
Hardy Marginals
Cut plants back to 6 inches from the top of pot. Place in bottom
of pond after first heavy frost.
Trim-hollow stemmed plants above water line to prevent rotting.
Tropical Marginals
Discard or winter over in greenhouse in tub or barrel filled with
water.
Tropical Floaters
Discard or winter over in greenhouse the same as Tropical
Marginal Plants.
Oxygenators (submerged)
Cut back to 3 inches above pot.
Place in bottom of pond.
FISH
Discontinue feeding when temperature drops below 50 degrees F.
Keep an area ice- free with floating pond de-icer. It provides an
oxygen/gas exchange.
PUMP and FILTER
Turn off pumps or filters. Remove. Clean filter. Store out of the
house as odor could become strong.
