Horticultural Calendar for San Antonio, Austin and Surrounding Areas

Week 1 -
Irrigate lawns only when grass blades first show signs of wilting in the morning. Apply 1/2- to 5/8-inch of water on each of two consecutive mornings to encourage deeper roots. If you water once a week during a drought (as the municipal water monopolies recommend), you'll promote shallow roots.

Cut back and discard foliage of west Texas Columbines. Do not compost leaves infested with leaf miners or spider mites.

Still time to sow Okra for summer and early fall production.

Week 2 -
Eradicate web worms when their nests are small. Use a product containing "Bt" (Bacillus thuringiensis).

Make sure your sprinkler system is not skipping a station or provides inadequate coverage.

Remove and discard all fruits from Catalpa, Paulownia and Trumpet Vine.

Protect ripening Figs, Grapes and Pomegranates from bird damage with netting, inflatable snakes, attack cats, owls, etc.

Week 3 -
Don't enrich your municipal water monopoly. Water most plants deeply on the day before they would have wilted.

Plant Asters, Firebush, perennial garden Mums, Salvias, etc. for fall bloom in sunny sites.

Water shady beds of English and Algerian Ivy only when their leaves first start to wilt.

Transplant: Eggplant, Peppers (both hot and sweet) and Tomatoes into prepared fall garden beds, in the evening. Keep them moist for two weeks.

Week 4 -
This is a good time for pruning Live Oaks and Red Oaks. Use a tree-wound dressing if you live near sites with Oak Wilt.

The driest time of the year is the best time to paint and reseal wooden outdoor furniture, decks and fences.

Feed Waterlilies with additional Agriform 2-year fertilizer tablets. Place them where fish or frogs cannot unearth them.

A black sooty mold on leaves is evidence of sucking bugs excreting honeydew. Kill those suckers with the least toxic, yet effective insecticide.

Week 1-
Inspect Crepe Myrtles weekly for aphids or powdery mildew. Consider replacing with mildew-resistant varieties.

Minimize expensive foundation damage. Water around the perimeter of your  slab-on-grade foundation every 2 to 3 weeks with a soaker hose.

If necessary, relocate spring-flowering bulbs, including perennial Daffodils, and replant immediately.

Finish pruning climbing Roses and all spring bloomers.

Harvest Garlic when "flower spike" starts to dry. Garlic without the spike should be ready in one more year.

Relocate all hanging baskets with sun-tolerant plants to a site which is shaded after 3:00 PM.

Remove spent flower spikes from all Salvia plants.

Week 2 -
Kill white fly, web worms and spider mites as soon as outbreaks occur.

Be careful near brush piles, weedy or overgrown areas and junk piles; a swarm of Africanized bees might lurk there.

Mow spring wildflowers after their seeds are mature.

Remove old, diseased Tomato, Pepper, Squash, etc. plants to clean up vegetable garden. Do NOT compost diseased plants.

Do not be a vector. Wash your hands after discarding virus-infected plants, and before touching disease-free plants.

Water young (less than two-years-old) trees and shrubs deeply every two weeks during a dry summer.

Week 3 -
Apply the first of two pyrethroid granule treatments for grubworm control in lawns  and beds. Use insecticidal granules only if you wish to also kill beneficial earthworms.

Remove and discard most Strawberry plants. Replant in early fall. Only the 'Selva' variety will bear in the summer.

This is a good time to prune Fig and Oleander and thin old wood on Pomegranate. Watch out for wasp nests.

Wear rubber gloves when harvesting the hottest of hot peppers: Dorset Naga, Naga Jolokia, Habanero, Red Savina, Scotch Bonnet, etc. Do not wipe your brow. If you do, you will soon experience a medical emergency.

Solarize your vegetable garden for the next three to four weeks.

Week 4 -
Tired of watering your lawn too frequently? Replace it with '609' or 'Stampede' Buffalograss in low-traffic sunny sites; 'El Toro' Zoysia in high-traffic full sun to part shade zones and 'Del-Mar' or 'Floratam' St. Augustine in shady areas with deep soils.

Control damaging insects on developing pecan nuts.

In case of very dry conditions, start watering your grounds to prevent fires caused by pyrotechnicians.

If you can reach them and if it is practical, remove Crepe Myrtle bloom spikes when half their flowers have lost their color.

Mulch all beds three- to four-inches-deep to keep soil cool, roots healthier, conserve moisture and reduce weed seed germination.

Before you irrigate, see if storms are approaching from the west.

Or, see if storms are approaching from the east.
