Things to do in October

Fertilize:

Fertilize existing beds of iris with well-rotted manure or balanced fertilizer. Reduce houseplant fertilizer by 1/2 for winter.

Water:

Water areas as needed.

Transplant:

Divide and transplant crowded perennials. Dig and store caladium bulbs. Dust with fungicide.

Prepare Soil:

Mulch gingers and other tropicals that overwinter outdoors to retain warmth and moisture and to control weeds. Falling leaves make autumn a good time to start a compost pile. Shred (or mow) leaves to speed decomposition. Turn compost pile periodically and keep it moist.

Lawn Care:

Fertilize with 3-1-2 ratio fertilizer. In newly-plugged lawns, sow 8 lbs. of ryegrass per 1000 sq. ft. to help hold soil. The seed grass will make a bright green carpet until spring, when hot weather will kill rye. Not recommended for established lawns. Mow every 5-7 days and leave the clippings on the lawn.

Diseases/Pests to look out for:

Check for cabbage loopers in the garden; spray with Bacillus thuringiensis (Bt). Make second treatment for brown patch on lawns with a history of the disease.

Prune:

Prune shrubs as needed, but save major pruning for the winter. Remove dead and damaged wood from shrubs and trees. Make cuttings of tender plants before frost.
