February
Week 1-
Any Impatiens, Purslane and Madagascar Periwinkle you see now at big box or corporate clone nurseries are just for display purposes. You shouldn't buy and plant them until mid-April.

Sow: Beets, Carrots, Mustard Greens, Peas, Radish, Spinach, Swiss Chard and Turnip in well-prepared beds in full sun.

Finish pruning Grape vines. Learn the different methods for Munson hybrid grapes and vinifera grapes. When your vinifera grapes start declining, replace them with 'Bailey', 'Brilliant', 'Champanel', 'Lomanto' & 'Valhalla'.

Collect, bag and refrigerate material for grafting or budding this spring.

Till composted organic matter and shredded Cereal (Elbon) Rye into vegetable garden soil.

Week 2 -
Palms with stippled, yellowed leaves have a magnesium deficiency. Apply annually a solution of one to two cups of epsom salts in 10 to 20 gallons of water in a three foot radius.

Apply pre-emergent herbicides now to stop germination of warm-season weeds in lawns, beds and landscaped areas.

Water and fertilize all winter annual bedding plants.

Prune Roses (except Climbers) on St. Valentine's Day.

Transplant: Broccoli, Cabbage, Cauliflower, Kale and seed Potatoes.

Remember to re-apply dormant oil before buds open on fruit and nut trees.

Buy small transplants of Tomatoes and Peppers and grow them in larger pots until the end of March. Protect them from temperatures below 50° F.

Week 3 -
Finish pruning Red Oaks and Live Oaks. Follow applicable local codes & regulations enacted by municipal corporations.  While these are not actually laws, be careful since Big Sibling might be watching!.

It is still time to prune fruit trees, even if buds have begun to expand. Seal cuts with exterior latex paint or a tree-wound dressing.

Burn all remaining Red Oak and Blackjack Oak firewood to reduce chance of spreading Oak Wilt.

Week 4 -

Make first sowing of Sweet Corn. Sow more in 10 days.

Side-dress (feed) Onion transplants with 21-0-0 every two weeks during growing season.

Protect fruit trees while they are blooming from bacterial diseases. Use Kocide for Apple and Pear; and Agri-Strep for Peach and Plum.

Remove winter-killed foliage from Bermudagrass, Zoysia and Buffalograss lawns. Use clippings as a mulch under shrubs or add to your compost pile.

Start removing winter mulch around sub-tropical perennials. Failure to remove that deep of a mulch keeps the soil cold, retarding their recovery, and increases their risk of rotting.

March
Week 1-
Remove protective winter mulch from subtropical perennials and replace in late April, as it gets hot.

Still time to mow well-established Asian Jasmine and feed with a slow-release lawn food (never use a weed and feed product).

Last chance to set out Broccoli, Cabbage and Cauliflower transplants this spring. Cover with netting to protect from insects.

Eradicate winter annual grasses from wildflower patches with appropriate selective herbicides before flower spikes appear.

Week 2 -
Prune back Bougainvillea and Hibiscus which have been in winter storage. Take them outdoors when growth resumes.

For an economical lawn, sow Bermudagrass in sunny sites, especially varieties like 'Sahara'.

Collect Live Oak leaves with your blower, rake or lawnmower and place in compost pile or as a mulch under ornamentals.

Beware the Ides of March! It could still freeze! The date of the latest freeze is still three weeks away.

Finish tilling in well-composted organic matter in sites where Tomatoes, Peppers and Squash will be grown.

Cut off any fruits produced on Daffodils, Irises and other spring bulbs.

Feed deciduous trees and shrubs as they resume growth with 15-5-10.

Week 3 -
If you must fertilize lawns this early, apply only all natural products, such as compost. Chemical fertilizers are applied after mid-April.

Let potting medium of Geraniums dry between waterings.

Do not disturb the soil where Begonias grew last season. Many will return as perennials.
