Pot and bring indoors some geraniums before first frost.
Transplant into small pots any cuttings taken earlier.
Some indoor herbs to consider planting this year would include oregano, thyme, parsley, sage, rosemary, sweet bay, chives, onions, garlic, pepper mint, spearmint and lemon balm.
If your water garden is shallow, lift hardy water lilies out of the pond, cut away the leaves and move to cool location
(40-50°F).
FERTILIZE
Use a slow-release fertilizer at planting time with hardy annuals.
Foliar feed all plantings and feed cool-season vegetables as needed.
Use lime in your vegetable/flower garden and on your lawn based upon the results of a soil test.
Apply a winterizer formula fertilizer (low nitrogen type) to St. Augustine (thru Nov).
Fertilize forced bulbs with water-soluble houseplant fertilizer.
Holly plants with a heavy set of fruit often suffer a fertilizer deficiency. An application of complete fertilizer late this month can be helpful and provide a head start next spring.
If not done in September, fertilize lawns with a slow-release, organic fertilizer with a 4-1-2 or 3-1-2 ratio. Final application of high nitrogen fertilizer should be applied in November. This late treatment will help the grass to green up faster in spring.
PRUNE/REMOVE
Now that the woody plants have completed their growth cycle, you can prune if you wish. Skip the spring bloomers - they get pruned after flowering next year.
Pick-prune shrubs as needed, but save major pruning for winter.
Remove dead and damaged wood from trees.
Prune away dead twigs for general clean up of roses.
Cut back lily stalks to soil level after they have turned yellow.
Enjoy fall annuals like mums, asters, and pansies. Cut back mums after they bloom. Deadhead pansies for prolific blooms all season long.
Pull up frost-tender plants (like marigolds, impatiens and zinnias) toward end of month before first expected freeze to allow room to cool-season annuals.
Thin turnip and radish plantings to give more room for roots to develop.
For bigger and better Brussels sprouts, pinch out the top of the plant when sprouts at the bottom are fully-grown.
WATER
Water cool-season vegetables, newly set out annuals/wildflowers and emerging seedlings during dry spells.
Keep forced bulbs potting medium moist (but not sopping wet).
PEST/DISEASE CONTROL
(always read and follow directions)
Remove cabbage loopers in your garden by using Bacillus thuringiensis (Bt) or
Dipel.
Watch for grass fungus (Brown Patch, etc.) use
Immunox, Immunox Plus or Lawn Fungicide Granules.
Handpull or hoe any weedy grass clumps and wild garlic (make sure ground is moist so you will get the bulb).
Pre-treat for spring weeds including spurweed sticker. Spread pre-emergent herbicide, FL Winterizer & Weed Preventer (common Bermuda and St. Augustine lawns only) or Balan (also prevents cool season weeds).
Continue insect and disease control on roses.
Inspect all plants before bringing indoors. Keep quarantined and treat for any pest infestation before exposing to other indoor plants.
Watch for storage diseases on bulbs.
ODD JOBS
Check your journal to see if there are any new plants or areas you want to develop. Continue to make notes in your journal of developments and ideas for spring.
Soil test lawns and garden areas (separately) if you havent done so already.
Continue to mow lawns at 2-1/2 inch to 3 inches. Grass clippings may be added directly to compost heap. Avoid adding soaking wet clippings to compost.
October is a good time to reduce the insect and disease potential in next years garden by removing all annuals that have completed their life cycle. Remove the tops of all herbaceous perennials that have finished flowering or as soon as frost has killed the leaves. Clean up orchard area: remove broken limbs, old fruit and debris.
Harvest sweet potatoes, gourds, pumpkins and winter squash before frost.
