Freezing temperatures have already arrived in parts of New Mexico, prompting seasoned garden professionals to offer practical advice for protecting plants during the cold season. Tammy Hayman, former owner of Rehm’s Nursery and Garden Center in Uptown Albuquerque, draws on two decades of experience to help local gardeners keep their beds and containers thriving.
Bring tender plants indoors
Hayman stresses that any herb or vegetable classified as “cold‑tender” – such as basil, cilantro, and other delicate herbs – should be covered or moved inside the home. “Anything that’s really cold‑tender, like your herbs, your basil, things like that, you’ll want to cover or bring them in,” she said. Houseplants that have been left outside also need to be brought inside promptly to avoid frost damage.
Use insecticidal soap when transitioning plants
When moving plants indoors, Hayman recommends a light spray of insecticidal soap to keep bugs from hitching a ride. “If you do discover a plant that you see a lot of flying insects or bugs, quarantine it away from the other plants or they might get infected,” she advised. This precaution helps prevent infestations that could spread to indoor collections.
Avoid leaf mulch that harbors insects
Many gardeners consider raked leaves a free source of mulch after the first frosts, but Hayman warns against this practice. Fallen leaves can shelter insects that later migrate to healthy plants. “Raked leaves also harbor insects,” she explained, urging gardeners to choose alternative mulches such as straw or pine needles.
Protect annuals and seasonal favorites
Annual flowers like marigolds, which are popular for Día de los Muertos celebrations on Nov. 1, should be covered with frost cloths or moved to a protected area. “Marigolds need covering or indoor protection to stay vibrant for Día de los Muertos,” Hayman noted.
Plant hardy crops for winter harvests
For those who wish to keep gardening through the colder months, Hayman suggests focusing on cold‑tolerant vegetables and flowers. Broccoli, Brussels sprouts, and other brassicas thrive in cooler weather, as do violas, pansies, and Johnny‑jump‑ups. These varieties can provide fresh produce and color well into winter.
Utilize heated grow‑houses
Rehm’s Nursery continues to operate a heated grow‑house, allowing the cultivation of a wider range of plants despite the chill. While most home gardeners may not have access to such facilities, the principle of providing consistent warmth and protection can be applied with simple cold frames or insulated containers.
By following these straightforward steps – moving tender plants indoors, treating them for insects, avoiding leaf mulch, covering annuals, and selecting hardy crops – Albuquerque residents can safeguard their gardens against the harsh winter weather and enjoy a vibrant landscape year‑round.
