What vegetables can you plant in March in Texas?

March is the time to start planting gardens full of your spring blooming favorites, vegetables like tomatoes or peppers, blooming shrubs, spring flowers, and more! For your vegetable gardens, start planting beds full of cool season vegetables. Vegetable varieties like leafy and root crops should be planted earlier in the month when the soil temperatures are generally cooler. Cool season vegetable plants include selections like swiss chard, lettuce, turnips, beets, collards, kale, cauliflower, and spinach. Leafy greens grow best in open, ground level areas with loose, nutrient rich, and well-draining soils like Calloway’s Organic Compost.


Going the organic way? Calloway’s Organic Compost stimulates beneficial microorganisms necessary for plant growth. It also helps balance the aeration and hydration ratio within your soil, creating soil that is lighter and drains well for healthy root systems, while allowing beneficial bacteria, fungi, and earthworms to flourish. This combination of organic material creates thriving, healthy and beautiful gardens.

Planting herbs is always a great idea, especially now that the weather is getting warmer! They can help fill your garden beds and container gardens with flavor. Choose from herbs like oregano, thyme, rosemary, chives, cilantro, parsley, and lavender.

Warm season vegetables can be planted in March. You may need to wait until late in the month if you are in central Texas, but the weather forecast may prove otherwise! The general rule of thumb is to wait one to two weeks after the average last day since killing frost. Ensuring the danger of frost has passed will help protect your warm season vegetable garden. Warm season vegetables consist of beans, corn, squash, cucumbers, melons, peppers, and tomato plants.


When planting gardens full of warm season veggies, you can choose plants for containers, in your vegetable beds, or display your edibles as ornamentals with your bedding plants and spring blooming shrubs. Plant like a master gardener and make sure your vegetables are planted in an area that receives plenty of full sun. It is also important to be sure to water your vegetable beds. You can fulfill the water needs of your vegetable plants by applying water slowly and deeply to help the root system grow strong. If watering a container garden, make sure there is a proper drainage hole so the water can soak through the root system and out the container.

What spring color can I plant now in Texas?

When should I start my spring lawn care?

It is time in Texas to create your new lawn. March is the month to lay fresh St. Augustine and bermuda sod. Wait another month to plant seeds to grow green bermuda grasses and wait to plant zoysia grass from sod.

For established lawns in North Texas, there still may be some remaining weed growth to control. Deter spring weeds and suppress weed growth with Bonide® Weed Beater Complete. Bonide® Weed Beater Complete attacks your weed problems in a couple ways. It contains a post-emergent which is what suppresses the weeds in your lawn, including crabgrass and many varieties of broadleaf weeds. It also contains a pre-emergent, preventing the production of new weeds in your lawn. Treat your lawn two times a year, during the spring and the fall. In South Texas, apply Nitro-Phos Barricade® Pre-emergence Herbicide. Nitro-Phos Barricade® contains selective turfgrass and landscape herbicides that prevent the germination of undesirable weeds. Perfect for Houston homes.

Another option is a more direct solution. Spray visible weeds with Bonide® Weed Beater Southern.

To start spring off right, make sure to mow your established lawn. Mowing will strip away the winter-killed stubble. March is also the time to start feeding your lawn. For your North Texas lawn, you may need to wait until later into the month to let the temperature outside heat up a bit more.

What are the pruning tasks for March in Texas?

Clean up your plants from the winter season and prune spring blooming shrubs, vines, trees, and more! When you prune spring plants or perennials, you are creating room for new growth. Give your evergreen shrubs a little attention to start the season off fresh. They need to be pruned before new leaves and growth can begin. You can prune as much as 25% of the plant if you trim each of the branches. Spring flowering shrubs and vines can be pruned when the plants finish blooming.

Trees can be pruned as a form of maintenance to remove low hanging and dead branches. Avoid any pruning contact with oaks during spring to lessen disease infestations like oak wilt fungus.
