- Remove diseased or insect infested debris from beds, such as leaves with fungus or insect damage that fall on the ground. Getting rid of this debris will reduce or eliminate any carryover on the ground or the soil of the insects or diseases you were fighting this summer.
- Rake leaves if there is a heavy accumulation on your lawn. A thick layer can smother and kill the grass, and can create a habitat for lawn insects or diseases. Try to be eco-conscious and rake leaves for composting, or chop them to tiny bits with a mulching mower. When leaves are chopped and left on the lawn, they decompose, adding desirable trace elements to the soil and improving its quality.
- Even though dandelions show up in spring, the best time to treat them is between September and November, because they’ve already begun to germinate. In the north, fall treatment can prevent weeds including dandelions (Taraxacum officinale), black medic (Medicago lupulina), plantain (Plantago major) and other broadleaf weeds.
Preen Weed Control makes this job easy. Here are some tips:
- Mow the lawn one or two days before application.
- If the soil is dry, water the lawn thoroughly the day before application.
- Apply in the morning when dew helps hold the herbicide on the plants.
- Do not water the lawn for two days after an application.
