A Calender for Gardening in the Bryan-College Station Area


PLAN: Now is the time to order gladiolus and dahlia bulbs. Get seed beds ready for such seed as nasturtium, petunia, pinks, scabiosa and snapdragon. Start plants of snapdragon, stock and tomatoes in flats if you have a sunny spot where you can protect them from freezes.

PRUNE: If plants were injured by freezing, wait until all danger of further frost has passed before pruning.

PLANT: Shrubs, roses and seedlings. Gladiolus after Jan. 20, being sure to cover lightly with 4″ soil.

FERTILIZE AND MULCH: Iris, crepe myrtle, trees, strawberries, day lilies.

INSECT AND DISEASE PROBLEMS: Any plants showing scale should be sprayed with dormant oil. Hand pick bagworms to remove eggs that will hatch in May and June to re-infect host plants. Watch for aphids. Remove piles of plant debris which may harbor pests such as sow-bugs, pill-bugs, millipedes, caterpillars and beetle larvae.

WEATHER PROTECTION: If a freeze is predicted, cover tender plants and shrubs with boxes or plastic trash cans [not metal]. Heavy paper also works well. After the freeze, remove cover promptly. If some frost has touched the leaves, spray with water before the sun shines on them.

BLOOMING: Calendula, narcissus, pansy, jasmine, loquat, flowering quince, roses, many hardy annuals, perennials.

Sow directly in the garden: spinach, mustard, turnips, beets, English peas, carrots.
Set out plants of cabbage and onion.
Start inside plants of pepper, eggplant and tomato.


PLAN: Start a garden diary with places for botanical names, dates for planting, fertilizing and blooming. Decide what to plant for constant color in the garden and to coordinate with your interior decoration. Start designing a pond with plans to show which plants will be in it. At the minute, I’m thinking of buying a Firecrest water lily as I think that would look beautiful, but I’m still undecided. Building and designing the pond will be hard work but I know it will all be worth it in the end!

PRUNE: Roses, grape vines, summer-blooming shrubs.

PLANT: Dahlia, Dutch Iris, cornflower, cosmos, daisy, larkspur, nasturtium, petunia, phlox, pinks, scabiosa, water lily seeds, cuttings of hardwoods, chrysanthemums, ivy and climbing fig. Perennials may be divided and set in their new positions.

FERTILIZE: Figs, gardenias, blooming bulbs, nandina and other shrubs, trees.

INSECT AND DISEASE PROBLEMS: Plants showing scale not sprayed in January. Spray infested trees with dormant oil if not sprayed in January. Look for white grubs in the garden.

WEATHER PROTECTION: Keep plants in good condition by watering, but not enough to activate growth.

BLOOMING: Flowering quince, pansies, pinks, snapdragon and sweet pea.

Sow directly radishes, spinach, lettuce, chard, mustard, turnips, beets, carrots and sweet corn.
Set out plants of onion, cabbage, broccoli and cauliflower.
Plant potato eyes.
Move tomato, eggplant and pepper plants to cold frame.
Start rooting sweet potatoes inside.


PLAN: Prepare soil to move mums next month if you divide plants rather than root new ones. Be sure to move each year. Pinch off tops for cuttings through May. Fertilize lightly each month until color shows in the bud. Use liquid fertilizer to force blossoms.

PRUNE: Finish pruning bush roses and dormant shrubs. Crepe myrtles may still be cut back one-third to one-half their height, but leave several buds to produce new shoots and to insure flowering. Prune any shrubs that have finished blooming.

PLANT: Cuttings taken from hardwood shrubs that have been pruned. Divide and reset cannas now. Canna beds need thinning every year for quality bloom. Set out plants of coral vine, dahlia, ferns, gerbera daisy, hibiscus, petunia, verbena. Seed planted after March 10 should grow.

FERTILIZE: Feed all roses, shrubs and plants with quick-acting fertilizer to stimulate rapid spring growth. Ageratum and flowering shrubs should not be too heavily fertilized at this time, because overfeeding of these tends to produce foliage at the expense of bloom. Do not allow fertilizer to touch stem or leaves of any young plants or seedlings unless it is a foliage fertilizer; it will cause them to scaled or rot. Trees may be fertilized this month. After ferilizing, be sure to mulch well. Also apply copperas or aluminum sulfate to gardenias. DO NOT fertilize grass this month as it is still partially dormant and cannot use the food, but the weeds can! It’s understandable that your grass may be looking a bit worse for wear in this month, with the cold and rain. If you’re finding your grass a bit too much to handle and want something to spruce up your garden, you may want to install plastic decking boards to replace your dead grass.

INSECT AND DISEASE PROBLEMS: Watch for red spider mite, aphids, thrips and bagworms. Begin looking for early-season leaf-feeding pests by the end of February and during March.

WEATHER PROTECTION: Watch for late frost and protect tender plants. Mulch against a hot dry summer. Water plants deeply if needed.

BLOOMING: All hardy annuals, many shrubs, trees and roses, many bulbs.

Sow directly radishes, lettuce, snap beans, dry beans, sweet corn, cucumber, okra, watermelon, and cantaloupes.
Set out plants of tomato, eggplant and pepper plants and protect against frost..

PRUNE: Early flowering trees and shrubs after they bloom.

PLANT: Coral vine, cosmos, elephant ears, gladiolus, hibiscus, marigolds, zinnias. Divide mums and place in beds prepared in March. Too early to plant periwinkles since they like warm soil.

FERTILIZE: Lawns, with extra fertilizer for areas under trees.

INSECT AND DISEASE PROBLEMS: Watch for black spot, aphids, caterpillars, beetles, mites, and whiteflies. Check roses after each rain and treat if necessary. Chinch bugs and brown spot my appear in the lawn.

BLOOMING: Spring flowering annuals, perennials. Begonias, cactus, canna, day lilies, many shrubs.

Sow southern peas, sweet corn, watermelon, cantaloupes and New Zealand spinach.
Set out sweet potato plants.


PLAN: To keep flowers cut to prolong blooming. Select bulbs for fall planting. Adjust the lawnmower blade so it does not cut too close.

PRUNE: Cut older canes of oleander, climbing roses and others which bloom on new growth. Prune pittosporum, ligustrum, junipers, etc. for compact growth.

PLANT: Cockscomb, cosmos, marigold, zinnia, balsam, impatiens.

FERTILIZE: Dahlias, every two weeks after buds appear until first bloom. Mums, monthly.

PRUNE: Pinch back mums for the last time. Cut out dead wood. Trim plants that need to be properly shaped. Crepe myrtle spent blooms may be pruned to encourage repeat blooming.

PLANT: This is not a good month for planting. If summer blooming seeds are planted, care must be taken to keep beds moist until germination occurs and well-watered afterward.

FERTILIZE: Mums, lawns, trees, and shrubs. Take care using fertilizer in hot weather – apply lightly and keep well-watered or plants will burn. Fertilizing can be important for both grass and plants. However, it’s important to fertilize correctly. If you’re not too confident with fertilizing, you can always contact a company like https://www.lawncare.net/service-areas/texas/ to see if they can give you advice, or even do it for you if they’re local to you.
