UPDATE: As winter approaches, experts are urgently advising homeowners to take immediate action to protect their Mexican Orange Blossom shrubs from plunging temperatures. This native shrub, also known as choisya, thrives in milder climates but struggles in colder zones, making it crucial for gardeners to implement protective measures NOW.
With the potential for temperatures to dip to as low as 5-10°F, homeowners in US hardiness zones 7-10 must act quickly to ensure the survival of their plants. “Even established shrubs can be vulnerable to harsh winter conditions,” warns Fernanda Varela, a designer from Seattle Sustainable Landscapes.
For those growing Mexican Orange Blossom in exposed gardens or colder regions, Varela stresses the importance of proper placement. “Plants nestled in south or west-facing corners, near structures that radiate warmth, stand a better chance of surviving winter,” she explains. If your plants are already in vulnerable spots, consider moving container-grown shrubs indoors, utilizing plant caddies for easy transport.
To effectively overwinter Mexican Orange Blossom, experts recommend two key strategies: mulching and wrapping. According to Varela, “A thick layer of mulch, ideally three to four inches, can significantly stabilize the root zone and prevent freezing damage.” Use compost or bark chippings, and ensure your plants are well-covered before extreme cold sets in.
In addition to mulching, Varela advises using breathable materials like burlap for wrapping shrubs. “Creating a temporary microclimate can make all the difference,” she notes, emphasizing that a loose drape of frost cloth can soften freezing winds. Remember to secure coverings without crushing the foliage beneath.
For those with container-grown Mexican Orange Blossoms, immediate action is critical. “Potted plants are especially vulnerable. Move them to sheltered areas like balconies or garages, or group them against a warm wall to create a protective microclimate,” suggests Nastya Vasylchyshyna, a botany expert from the Plantum app. Insulate pots with bubble wrap or burlap, and consider additional layers like straw for enhanced protection.
As winter progresses, water your container plants sparingly and refrain from fertilizing until spring. Varela also cautions against allowing wet snow to accumulate on branches, which can lead to structural damage. “Gently brush off snow after heavy falls to prevent ice from forming,” she advises.
Immediate preparation can mean the difference between life and death for these beloved shrubs. Homeowners are urged to act now to safeguard their Mexican Orange Blossom plants from the impending cold.
Next Steps: Gather materials like organic mulch, bubble wrap, and frost covers to begin winterizing your plants today. Don’t wait until the first frost to take action—protect your garden’s future now!
