How to Grow Collard Greens in Florida: A Comprehensive Guide

Collard greens, also known as collards, are a nutritious and versatile vegetable that thrives in the warm climate of Florida. Packed with vitamins A, C, and K, along with calcium and fiber, collard greens are a fantastic addition to any garden. Whether you are a seasoned gardener or a beginner, this article will provide you with all the information you need to successfully grow collard greens in Florida.

Choosing the Right Variety

Before you start planting collard greens, it is important to choose the right variety for your garden. Some popular varieties that are well-suited for Florida’s climate include Flash, Top Bunch, Georgia Southern, and Morris Heading. These varieties are heat-tolerant and can withstand the hot and humid conditions of Florida.

Preparing the Soil

Collard greens prefer well-drained soil that is rich in organic matter. Begin by clearing the area of any weeds or debris. Loosen the soil using a garden fork or tiller to a depth of 8-10 inches. Incorporate organic matter such as compost or aged manure into the soil to improve its fertility and drainage.

Planting Collard Greens

Collard greens can be started from seeds or transplants. If you choose to start from seeds, sow them directly into the prepared soil. Plant the seeds about ¼ to ½ inch deep and 2-3 inches apart. Once the seedlings emerge, thin them to about 12-18 inches apart to provide enough space for the plants to grow.

If you prefer to start with transplants, purchase healthy seedlings from a reputable nursery. Dig a hole slightly larger than the root ball of the plant and place it in the hole, ensuring that the top of the root ball is level with the soil surface. Space the transplants 12-18 inches apart to allow for proper growth.

Caring for Collard Greens

Watering: Collard greens require consistent moisture, especially during dry periods. Water the plants deeply, providing about 1 inch of water per week. Avoid overhead watering as it can lead to disease. Instead, use a soaker hose or water at the base of the plants.

Fertilizing: Collard greens are heavy feeders and benefit from regular fertilization. Apply a balanced granular fertilizer, such as a 10-10-10 formula, every 4-6 weeks throughout the growing season. Follow the instructions on the fertilizer package for application rates.

Pest and Disease Control: Collard greens are relatively pest and disease resistant. However, some common pests that may attack them include aphids, cabbage worms, and flea beetles. Monitor your plants regularly and take appropriate measures, such as using organic insecticides or introducing beneficial insects, to control pests. Diseases like downy mildew and black rot can be prevented by practicing crop rotation and ensuring good air circulation around the plants.

Harvesting Collard Greens

Collard greens are typically ready for harvest 60-85 days after planting, depending on the variety. Begin harvesting the outer leaves when they reach 10-12 inches in length. Pick the leaves individually, starting from the bottom of the plant, or cut the entire plant at ground level. Regular harvesting encourages new growth and prolongs the harvest season.


Q: When is the best time to plant collard greens in Florida?
