During the winter season we gardeners usually do not spend much time outside in our gardens. However, it won’t be long before warmer days arrive so use some time in February to prepare for spring!
- Do not apply “weed and feed” products. These contain both fertilizer and weed killer, but it is too early to fertilize warm season lawns such as Centipede, Bermuda, Zoysia and St. Augustine grass.
- Late February is the best time to get out early applications of preemergence herbicides for crabgrass (aka crabgrass preventer). Many products are granular allowing easier spread.
- Tune up your lawn mowers and other lawn equipment to be ready for spring by sharpening, replacing blades and changing oil.
- Annual winter weeds like henbit, chickweed and lawn burweed are common in the lawn during this time. To control these weeds, a post-emergent broadleaf herbicide with 2-4D can be used. Apply herbicides on a warm day in order to be more effective. Centipede grass is sensitive to 2-4D so apply at a lower rate. Before using any herbicide, read the product label and apply according to the label directions and follow good safety practices.
Trees, Shrubs and Flowers
- Late February is the time to be pruning crape myrtles and other summer blooming shrubs (butterfly bush, lantana, gardenia, nandina, abelia, roses) as these plants produce flowers on the new growth that occurs in the spring.
- Now is the time to buy your summer and fall flowering bulbs, such as dahlias, gladioli, cannas, caladiums and lilies. Don’t plant them yet, but wait for warmer weather (the soil temperature must be at least 55 degrees F).
- Rose pruning should be done as leaf buds begin to swell, usually late February into early March. Prune shrub roses (knock-out roses) back to 3 to 5 finger sized canes 18 to 24 inches long.
- Do not trim hydrangeas. Their stems may look dead but they contain this spring’s flower buds.
- February is a good time to cut back ornamental grasses. For shorter grasses cut to 4 to 6 inches in height. For pampas grass cut to a 6 to 12 inch height. Avoid cutting any new growth. Remember to wear gloves when cutting pampas and you can pull back the top with a rope to allow for easier cutting.
- Interested in propagating some plants. Now is the time to take hardwood cuttings from shrubs. Crape myrtles, viburnum and figs are very easy to root this way.
Fruit, Vegetables and Herbs
- Start growing your own salad garden! Direct sow loose leaf lettuce, arugula, spinach, mesclun mixes, carrots and radish in late February.
- By late February, start pepper, tomato and eggplant seeds indoors to have transplants ready in mid-April. These crops need direct light and warm temperatures above 60°.
- Onion sets can be planted in the garden in February for harvest in May and June. Bee sure to plant short day varieties such as Candy, Granex (white), Stockton Sweet Red, Texas Early Grano and Yellow Granex.
- Plant seed potatoes in the garden for harvest in late May-early June.
- Prune fruiting plants such as grapevines, blueberries, and fruit trees.
- Spray your tree fruits this month with a dormant soil to control mites and scale. The oil simply covers the tree and suffocates the insects. (Note- do not apply dormant oil when the tree is not dormant. Doing so in the spring, summer, and fall will cause damage.)
- Direct sow other cool season vegetables such as beet, rutabagas, swiss chard, kale, mustard and turnip seed. Broccoli plants can also be set out during this time.
