FERTILIZE

• If grass needs to be mowed, then it is ready to fertilize (thru April). Do that after about 2nd mowing.

• Wait until April to fertilize warm season lawn grasses and until May for Centipede

• Vegetables: a month after growth starts

• Fruit and pecan trees

• Houseplants with a diluted solution of soluble houseplant food after new growth appears

• Spring-flowering bulbs after leaves appear and before they bloom

• Use a slow-release fertilizer according to soil test on perennials

• Roses after pruning and before they leaf out

• All blooming ornamentals: forsythia, quince, spirea, climbing roses, camellias, azaleas, etc….
………… only after they bloom!!! ………

PRUNE

• Spring-flowering shrubs and vines only after they finish blooming !!! Azaleas, flowering quince, spirea, forsythia, weigela, camellias, Carolina jasmine, wisteria, Lady Banksia rose, etc.

• Fruit trees just before bud break

• To keep pines as a dense hedge, trim new growth or “candles,” trim when new needles are about half the length of the old needles 

• Give hibiscus a haircut, then feed with hibiscus food to encourage lush growth

• Gradually move potted hibiscus into more light

• Fig trees, Red Tip Photenias, or shape hibiscus

• Leggy perennials

• Ornamental grasses to new shoots

• DO NOT remove leaves from daffodils and jonquils until AFTER they yellow

• Remove all dead blooms from bulbs

• Pinch off tips of sweet pea seedlings and mums when they are 4” tall

• End of month pinch back growing tips of houseplants that have become rangy and to promote branching and fullness

• Cut branches from early spring flowering bushes for forcing

• Winterkilled leaves from plants around water gardens before and when new growth appears and compost trimmings

.WATER

• Soak mail-order bare-root plants before planting

• Annuals and other dry soil areas as needed

• Keep newly planted perennials moist

• Newly planted roses often enough to keep roots moist during first few weeks. Gradually reduce the frequency but not the depth of watering.

• Newly planted shrubs every few weeks in dry weather

• Wildflower areas in dry months

• Water lawn well if you want it to spread faster to fill in dead areas

• Observe areas of poor drainage, fill in low spots or create a channel for drainage

PEST CONTROL

• Fruit trees: Fruit tree spray, Captan

• Worms and caterpillars: Bacillus thuringiensis (Bt), Dipel, Thuricide

• Pillbugs, snails, slugs: DE/garlic spray, beer traps, rotenone/pyrethrum spray

• Aphids: soap and water of garlic spray, release of ladybugs, insecticidal soap, Triple Action

• Flower thrips on bellfower, daylily and peony flowers, remove and discard infected flowers (do not put in compost pile!)

• Bagworms on evergreens, remove bags and discard

• Leaf-streak on daylilies, remove and discard infected leaves (do not put in compost pile!)

• Fungus: Black spot, powdery mildew, bacterial leaf spot: baking soda (1 ½ tablespoons and 2 tablespoons vegetable oil per gallon of water), 
Immunox Plus

• Gray mold on foliage of bulbs

• Weeds – Early March: pre-emergent herbicide, Balan, HY Crabgrass Control

• Handpull winter annuals such as henbit and common chickweed

• Weed your flowerbeds making sure not to pull any desirable plants

• Remove weeds before they have a chance to flower and go to seed

ODD JOBS

• Plan flowerbeds, gardens and herb gardens in your journal

• Note in your journal the placement of houseplants when they will go outside to determine where to plant your annuals, perennials and shrubs

• Soil test

• Repair damaged areas of the lawn (dethatch, rake or aerate) prior to fertilizing

• Turn the compost pile, add any coarse mulch removed from the garden

• Use completed compost for bed preparation-use partially completed compost as a top-dressing mulch or return to compost pile

• Mulch all bare soil

• Check mulch underneath shrubs, add more if needed

• Remove mulch gradually from flowerbeds. This will help acclimate the plants with the temperature changes and help with weed 
prevention.

• Remove winter coverings from roses when forsythia is in full bloom (still watch weather for cool nights)

• Finish your winter cleanup, including floating debris from the surface of water gardens

• Repair any damaged fencing, arbors or trellis work

• Watch for freezing weather so you can use coverings to protect the plants

• Maintain your coldframe. Keep it open on warm, sunny days to prevent plants from overheating

• Check supports on newly planted trees

• Check your lawn mower, especially sharpening the blades, before starting to mow

• Check any overwintered bulbs and plants (including aquatics) to insure they are still healthy and haven’t dried out

• Photograph spring-flowering gardens for reference later in the year

• Clean out birdhouses

• Feed the birds!
