Late September can be a busy time for gardeners

Late September typically feels like fall, but it can be a productive time for gardeners to accomplish a range of tasks.

If lawns are in need of broad-leaved weed control, this is the ideal time to apply a herbicide, preferably one that mixes two or three chemicals to work on the widest range of weeds.

The lawn can also be fed now and/or in late October through early November. The best time for aerating lawns has passed, but both aeration and fertilization can be taken care of in April.

Many of us feel that perennial borders and patios are in need of a color boost. Big pots of chrysanthemums already in bloom are just right for brightening up those spaces.

However, fall-planted chrysanthemums are unlikely to do well if planted in garden soil. Typically, they do not winter over very successfully. Those wanting late-season border blooms should plant small chrysanthemums and asters next spring to reap a fine fall reward.

In the vegetable garden, you may be able to sow and harvest one more crop of radishes, leaf lettuce, and spinach. If you have a large garden, consider sowing a cover crop of winter wheat or rye and turning it under next spring.

It is not too early at all to think about the approaching cold season. One important step is considering which plants you will try to bring inside and winter over.

First, examine any possibilities carefully to be sure that no insects or eggs are riding along. If some plants are very large, consider cutting them back about one-third. That will allow precious winter light to reach the plant's center more easily and give the plant's roots less mass to support.

If it is feasible for at least some of the plants coming indoors, try bringing them in for a few hours at a time so that the huge change from outdoors to indoors is not quite so abrupt.

Finally, consider stocking up on some bulbs for indoor use. Paperwhites can of course be forced very successfully. If you are a gardener whose tulips are often eaten by deer, consider forcing some tulips as well. You'll be able to enjoy the unparalleled form and color of those blooms with less worry
