Gardening Tips for September
- Plant peonies now, but make sure the crowns are buried only one and a half to two inches below ground level. Planting them deeper than two inches may keep them from blooming.
- Get a jump on next years lawn and gardens by having a soil test done through the UConn Soil Nutrient Analysis Laboratory.
- Now is the time to de-thatch and aerate lawns to promote root growth.
- Remove bagworm egg masses from evergreen shrubs to eliminate the spring hatch from over-wintered eggs.
- Apply fall fertilizer to lawns between Sept. 15th and Oct. 15th.
- Continue to water any new shrub or tree plantings until the first hard frost.
- Rake up leaves, twigs, and fruit from crabapple trees and throw them in the garbage to help control apple scab disease.
- Limit herbaceous plant material located a few feet away from the house to eliminate hiding places for insects and mice that could wind up indoors as temperatures plummet.
- As tomatoes end their production, cut down plants, pick up any debris and put dead/diseased plant parts in the trash or take to a landfill. Many diseases will over-winter on old infected leaves and stems so these are best removed from the property.
- Dig and store tender bulbs like dahlias, caladiums, cannas, and tuberous begonias.
Despite good cultural practices, pests and diseases at times may appear. Chemical control should be used only after all other methods have failed.
