Planning Your Fall Vegetable Garden

It’s hard to think about a fall vegetable garden when temperatures are soaring into the 90s, but now is the perfect time to begin planning your fall vegetable garden. In Central Florida, July and August are ideal months to prepare your garden and start seeds for cool-season vegetables. Taking time to plan before planting will help you grow a productive garden and avoid many common gardening challenges.

Whether you are planting your very first vegetable garden or preparing an established one for another growing season, these three simple steps will help set you up for success.

1. START WITH A GARDEN PLAN

A successful vegetable garden begins with thoughtful planning. Before purchasing seeds or plants, decide how much space you want to dedicate to your garden and choose the growing method that best fits your landscape and lifestyle. Vegetables can be grown directly in the ground, in raised beds, in containers, or using a combination of these methods.

Select a location that receives at least six to eight hours of direct sunlight each day, has access to irrigation, and is convenient for regular maintenance and harvesting. Sketching a simple garden layout before planting can help you determine how many plants your space will accommodate and prevent overcrowding.

If you have limited space, consider incorporating edible plants into your ornamental landscape. Many vegetables and herbs provide colorful foliage, attractive flowers, and interesting textures while also producing fresh food.

For new gardeners, it is tempting to plant everything at once. However, starting with a smaller garden allows you to gain experience and establish a routine for watering, fertilizing, scouting for pests, and harvesting. You can always expand your garden in future seasons.

2. PREPARE YOUR GARDEN FOR PLANTING

Proper site preparation is one of the most important steps toward a productive fall garden. If you are replanting an existing garden, begin by removing weeds and any dead or diseased plant material. Cleaning the garden helps reduce insects and plant diseases that can carry over from previous seasons.

Next, test your soil. A soil test provides valuable information about soil pH and nutrient levels, allowing you to make amendments only when needed. Most vegetables grow best in soils with a pH between 5.5 and 7.0. Soil tests are provided for a small fee at most UF/ IFAS Extension Service offices. Improve the soil by incorporating organic matter such as finished compost before planting. Organic matter increases water-holding capacity, improves drainage, and supports healthy root development. Follow UF/IFAS recommendations for compost and manure applications and avoid applying excessive amounts as this can damage your new plants.

If you are growing vegetables in raised beds or containers, use a high-quality, well-drained potting mix rather than garden soil. Gardeners interested in making their own potting mix can find a recipe at: sfyl.ifas.ufl.edu/lawn-and-garden/homemade-pottingmix. Soil will need to be replaced and/or amended each season. Your soil test will guide you as to what you need to add to help the soil support your fall vegetable garden.

3. PLANT COOL-SEASON VEGETABLES AND HERBS

Central Florida’s fall growing season offers an excellent opportunity to grow many vegetables and herbs that struggle during the heat of summer. Depending on the crop, you can plant seeds directly in the garden or start with healthy transplants. Find free seeds at the Seed Library located at the UF/IFAS Polk County Extension office or local libraries around Polk County.

Popular fall vegetables include:

• Arugula

• Beets

• Broccoli

• Brussels sprouts

• Cabbage

• Cauliflower

• Collards

• Kale

• Lettuce

• Mustard greens

• Onions

• Radishes

• Spinach

• Swiss chard

• Sweet potatoes

Many herbs also thrive during the fall growing season, including:

• Cilantro

• Dill

• Fennel

• Garlic

• Mint

• Parsley

Planting dates vary by crop, so consult the UF/IFAS Florida Vegetable Gardening Guide at ask.ifas.ufl.edu/publication/ VH021 for recommended planting windows, varieties that grow best in Central Florida, fertilization guidelines, and pest management recommendations.

One of the best habits gardeners can develop is keeping a garden journal. Use a journal to record where each crop is planted, planting dates, varieties grown, harvest yields, pest problems, and notes about what worked well throughout the season. These records make crop rotation much easier. Rotating crops means avoiding planting vegetables from the same plant family in the same location season after season. Crop rotation helps reduce insect issues and diseases while promoting healthier plants and better harvests over time. Contact the UF/IFAS Extension Polk County Plant Clinic for a handy guide on crop rotation.
