April Gardening To Do List

April To-Do List

Plant: ornamental & wildlife

• Annuals: seed or transplant zinnias, cosmos, sunflowers, Mexican sunflower—all good wildlife annuals. Transplant: Salvia coccineas, a native that butterflies and bees just love. Avoid planting caladiums.

• Succulents (agave, yucca, other succulents)

• Perennials & vines

• Esperanza (Tecoma stans)

• Ornamental (clumping) grasses like muhly and Mexican feather grass

• Shrubs

• Clean up and replant containers—annuals, perennials, herbs, hibiscus, vegetables in larger containers

• Top new containers with light layer of mulch to conserve water; use decomposed granite, pea gravel or other grit for potted succulents

• Trees if you keep them watered! Deeply to at least 3”. Don’t water if soil is moist to 3”.

Plant: herbs

• Basil, catnip/catmint, comfrey, fennel, horseradish, feverfew, oregano, thyme, rosemary, Mexican mint marigold, peppermint, lemongrass, lemon balm, lemon verbena, bay laurel

Plant: food crops

• Chard, corn, cucumber, eggplant, endive, Malabar spinach, mustard, peppers, pumpkin, summer & winter squash, tomatillos (you need at least two!), tomatoes, beans, cantaloupe

• Texas A&M AgriLife Extension Vegetable Planting Guides (Central Texas) http://aggie-horticulture.tamu.edu/travis/home-landscape/edible-gardens/growing-vegetables/

Prune

• Trees: DO NOT prune red oaks and live oaks unless damaged. Spray immediately with clear varnish.

• No need to apply pruning paint to other trees

• Dead head flowering plants

• Prune spring bulbs only when foliage is brown

• Bougainvilleas if not already pruned for overwintering

Move/Divide

• Succulents

Fertilize

• Lawns. Use an 8-2-4 or other similar ratio. Do not use Weed and Feed products!

• Add compost to beds if not already. Mulch as you cut back dormant perennials. Fertilize with slow-release granular late in the month or as dormant perennials leaf out

• Add compost around trees and fertilize. Be sure to dig out grass several feet from the trunk, ideally to the drip line of the tree canopy.

• Citrus with high nitrogen fertilizer like Citrus-tone. Fertilize every few weeks through growing season.

Insects

• Watch for aphids and spider mites. It’s easy to spray them off with a hard blast of water. Be sure to get the undersides of the leaves.

• Ladybugs and green lacewings will be chomping down those aphids, so watch for them and their larvae.

• Aphids and other insects can create sooty mold on plants, a fungus that develops from their secretions (honeydew). Wash off the culprits and the leaves. Remove damaged leaves to the trash (not the compost pile).

• Watch for tomato hornworms on tomatoes: squish or spray the plants with Bt (Bacillus thuringiensis), a natural caterpillar control that won’t harm you or pets–only caterpillars!

• To fend off squash vine borers, keep row cover on and hand pollinate. Or take your chances with natural bee pollinators!

• Walk the garden in early morning to pick off stink bugs and largus bugs from tomatoes. Check under the leaves for eggs.

• Deploy grasshoppers while young. If you wait, you won’t be able to deal with them. Effective baits include Nolo Bait or Semaspore. Both contain a protozoa called Nosema locustae which is impregnated in bran flakes sweetened with sugar. Apply by hand or with a rotary spreader, early in the morning, when grasshoppers are feeding.

Lawn

• Plant new lawn. Keep watered until established

• Mow weeds before they set seed

• Fertilize with an 8-2-4 or other similar ratio. Do not use Weed and Feed products!

• Mow to keep weeds from going to seed. Leave clippings on the lawn unless you have weed seeds.

Prep

• Add compost to vegetable gardens along with organic fertilizer in prep for more summer crops

• Soil test

Other tasks

• Watch for powdery mildew. Apply a natural fungicide like Serenade if necessary. Generally, it goes away naturally. Avoid watering leaves at night.

• Mulch, but avoid touching the base of trees and roses

• WEED! Do not let weeds go to seed. Do not apply chemicals: pull them up or mow down before they set seed.

• When moving plants back outside, do it gradually. Prune and lightly fertilize. Lightly mulch.

Tips

• When planting, dig hole twice as wide as root ball but no deeper than where it sits in the pot.

• Backfill and water until it sinks in.

• Continue filling in.

• Water again until it sinks in and pack the soil down.

• Mulch.

• Plant flowers in your vegetable garden to encourage bee pollinators.
