When can you plant your garden in Fort Worth?

In Fort Worth, the ideal planting times for various plants can be determined by considering the USDA hardiness zone of the region. Fort Worth falls under USDA hardiness zone 8a, which means it experiences an average minimum temperature range of 10-15°F (-12 to -9°C).

  1. Spring Planting: In Fort Worth, the spring season is typically the best time for planting a wide range of plants.

  2. Fall Planting: Fall is another excellent planting season in Fort Worth. As the temperatures start to cool down, it is a great time to plant cool-season vegetables such as broccoli, cauliflower, carrots, and radishes. Additionally, fall is an ideal time for planting trees, shrubs, and perennials, as it allows them to establish their root systems before the arrival of winter.
