Because this month tends to be so dry, supplemental applications of water are required by your lawn and plants. January is also an important month for gardeners in South Florida to fertilize tropical fruit trees, lawns, and shrubs.

Cold protection: Bring sensitive plants like orchids inside if a frost or freeze is predicted.

Pests: Apply horticultural oil to citrus, shrubs, and deciduous fruit trees while plants are dormant to control scale.
