Gardening advice for protecting sensitive plants from autumn frost

As temperatures begin to drop at night, gardeners are advised to take specific precautions to protect sensitive plants from frost. While daytime temperatures may remain pleasant, nighttime dips can damage various species.

Exotic plants grown in containers, such as hibiscus, mandevilla, bougainvillea, lantana, fuchsia, and citrus, require immediate attention. Plants in pots are particularly vulnerable because their root balls freeze more quickly than those in the ground. Moving these to a greenhouse, conservatory, or a sheltered area against a house wall is recommended. For plants that cannot be moved, using white non-woven fabrics or jute covers can provide necessary protection.

Specific care is also needed for common herbs like basil, which suffers when temperatures fall below 10 °C. Additionally, hardy-looking plants like oleander require careful winter preparation. To ensure oleanders bloom again in the next season, they should be moved to a protected space before frost arrives, as their roots in containers are highly exposed to the cold. Gardeners should also inspect plants for pests like scale insects or mites before wintering them.
