January Gardening Tips for Harris County Residents: Preparing for the Cold Front and More
As January ushers in cooler weather, Harris County residents should make sure their gardens are well-prepared for the challenges of winter. From preparing for an impending cold front to planning ahead for spring planting, there are several essential tasks to tackle this month. Karen Shook, a Harris County Master Gardener, has provided helpful tips for gardening in January, with a special focus on protecting plants from cold weather.
Get Your Garden Ready for the Cold Weather
According to the National Weather Service Houston/Galveston, a strong cold front is expected to bring much colder temperatures to Southeast Texas in the coming week. Residents can expect below-freezing conditions, which may last for several nights. As temperatures dip, it’s important to take action to protect plants from the cold.
“It’s crucial to stay prepared for the cold snap next week,” says Shook. “Plants can suffer damage when exposed to freezing temperatures, especially those that are sensitive to the cold.”
How to Protect Your Plants from Frost and Freeze
There are several methods to safeguard your plants when a cold front hits:
-
Frost Protection: If the weather is expected to dip into the low 30s, use frost covers such as blankets, sheets, or frost blankets. “Covering plants loosely with frost blankets can help slow down their cooling and provide some insulation,” says Shook. “Make sure the covers are not touching the plants directly, as this can cause damage.”
-
Freeze Protection: For colder temperatures (below 32°F), it’s essential to secure the covers to the ground to trap heat. Shook recommends adding a safe heat source, such as heat-producing holiday string lights like C9 lights or a clamp-on floodlight with a heat lamp bulb, to provide additional warmth.
-
Water Before the Freeze: Shook advises watering your plants if the soil is dry before the cold sets in. “Watering plants before a freeze is vital because moist soil helps retain heat, which can protect your plants during freezing nights,” she explains.
-
Move Plants to Protected Areas: If possible, move potted plants under the eaves of your house, onto patios, or near buildings that can provide additional warmth.

Tasks to Tackle in Your Garden This Month
While preparing for cold weather is a top priority, January is also a good time to focus on other gardening tasks that will set you up for success in spring. Here’s what to do:
Soil Testing
January is an ideal time for a soil test, allowing plenty of time for any necessary amendments before spring planting. “Soil tests can help you determine the right pH and nutrient levels in your garden soil,” advises Shook. “This gives you the opportunity to correct any imbalances early.”
Planting and Seed Starting
For those planning ahead for spring, January is a good time to start seeds indoors. Choose fast-growing annuals like alyssum, phlox, and calendula. “Look at your seed packets for guidance on how long it will take for plants to reach transplant size and determine when to start them indoors,” says Shook.
For cool-season crops like broccoli, cauliflower, and collards, consider planting transplants directly into your garden. Shook reminds gardeners in Zone 9 to continue planting cool-season annuals such as pansies, dianthus, and snapdragons through the month of January.
Prune and Divide Perennials
January is also a great time to divide and move summer- and fall-blooming perennials, as well as ornamental grasses. “Cut back any brown foliage before lifting, dividing, and replanting,” advises Shook. Make sure to keep mulch around the crowns and roots of less-hardy perennials to protect them during the cold months.
Roses, Shrubs, and Trees
January through early February is an optimal time to plant or transplant roses. Shook also recommends checking shrubs like camellias, hollies, and euonymus for scale insects. If necessary, apply horticultural oil sprays according to the product label for effective pest control.
When it comes to trees and shrubs, this is a good time to transplant or prune them. Just remember that pruning requirements vary by type of fruit tree.
Lawns and Groundcovers
Keep lawns raked to allow sunlight to reach the grass and prevent fungal growth. For any weeds that have sprouted, use pre-emergent herbicide or remove them by hand. January is also a good month to clean up existing groundcovers with a string trimmer or mower, and to plant hardy perennial groundcovers.

Planning Ahead for Spring
While the cold weather may dominate January, it’s also a time to plan for the warmer months ahead. Consider setting up a spring vegetable garden, starting seeds indoors for plants that will be ready for transplanting once the weather warms up.
For those looking to plant spring-blooming bulbs like tulips and hyacinths, it’s not too late to get them in the ground if you haven’t already. Be sure to keep beds weed-free and mulched as these bulbs begin to grow.
Final Thoughts
January is a month of preparation for gardeners in Harris County, with opportunities to protect plants from the cold and set the stage for a successful spring season.
