USDA Zone 10, with winter temperatures rarely dropping below 30°F to 40°F, offers a subtropical climate that tantalizes gardeners with the opportunity to grow exotic and tropical plants year-round. This zone encompasses southern Florida, parts of southern Texas, and small areas along California’s southern coast. Let’s delve into this exciting world of gardening, where winter frost is virtually a stranger.

These can be detrimental to certain plants, demanding careful species selection.

2. Pests and Diseases

The warm climate can lead to abundant pests and diseases that thrive year-round.

3. Limited Cold-Hardy Plants

Some temperate plants that require chill hours might struggle in this zone.

4. Water Management

In some regions, limited rainfall necessitates efficient water management practices.
