Growing Asian vegetable crops in Florida has become an increasing trend over the last decade, mostly due to health benefits and profitability by producers. However, the crop is new to many, who are interested in growing and consuming these vegetables. There are two sub-species of Chinese cabbage. The Pe-Tsai group are the broad leaved, compact heading varieties. The head may be six inches across and either round or cylindrical, in shape. The second group is known as Bok Choy (figure). These are non-heading Chinese cabbage varieties that have several thick, white leaf stalks, and smooth glossy, dark green leaf blades clustered together, similar to the way celery grows.
Again, cooler temperatures are key. Warm temps cause the plant to uptake more calcium, making the heads soft and bitter and may contribute to early seed development through bolting. Chinese cabbage matures in around forty to seventy-five days from planting, depending on variety. There’s no specific requirements to growing this cabbage in Florida, just follow the same soil preparation, liming, fertilization, and cultivation practices that you would use for other leafy vegetable garden crops. The main pests and diseases that occur are leaf blight, downy mildew, aphids, and cabbage caterpillars. Leaf blight and downy mildew usually occur in warmer times of the year, with higher temperatures and rain.
Chinese cabbage is very versatile. It’s great in salads, stir fry, pickled and even as a replacement for lettuce on your favorite sandwich. Enjoy!

Step-by-Step Instructions: Indirect Seeding Fall Veggies
While summer gardens offer a variety of intriguing fruiting crops, I have a special fondness for gardening during the fall season. This preference stems from the reduced pest pressure, decreased need for watering, fewer weeds, and the more favorable cooler temperatures for completing gardening tasks. Although it generally offers a more straightforward gardening experience, achieving success with your fall garden still hinges on applying the right techniques, with one crucial aspect being the care for seeds and young seedlings.
Indirect seeding allows you to nurture your seedlings before they establish their permanent residence in your garden, ensuring their growth into robust, mature plants. Below, you’ll discover a step-by-step guide to indirect seeding and planting for fall vegetables. By following these instructions, you’ll get a head start in cultivating a thriving fall garden that will delight your taste buds.
Seeding into Starter Cells:
While many crops can be started indirectly in starter cells, it’s important to note that root vegetables (such as beets, carrots, radishes, turnips, etc.), peas, and beans are exceptions due to their delicate root systems, which do not transplant well. These particular crops thrive when directly seeded into the garden. Conversely, fall crops that typically benefit from indoor seeding include Brussels sprouts, broccoli, cabbage, cauliflower, cilantro, kale, lettuce, mustards, parsley, spinach, and Swiss chard. For Florida planting dates, transplant ability, and other detailed planting information, see Table 1 in the UF/IFAS publication Florida Vegetable Gardening Guide.

Begin by moistening a starting mix, which is any fine-textured growing medium designed to support seed germination and early seedling development. Fill seed starter cells with this prepared mix, ensuring a level, flat surface.
Create shallow indentations (2-3 times the diameter of the seed) in the starting mix in each starter cell using your finger and place 1-2 seeds in each cell. (Remove all but the strongest seedling if multiple seeds germinate in the same cell.)
To ensure even coverage and prevent clumping, lightly sprinkle dry starting mix over the seeds.
Label with the crop name, variety, and date.
Mist the surface with water from a spray bottle, pump sprayer, or a hose spray nozzle. Maintain moisture levels, avoiding waterlogging.
Before the seeds germinate, keep them in a temperature-controlled room or out of direct sunlight. Germination time varies, but typically takes 5 to 14 days, depending on the crop, environmental conditions, and seed quality. (For fall varieties, germination is best between 50-80°F.)
As soon as seedlings emerge, move them to a sunny location with more than 6 hours of direct sunlight. If temperatures exceed 85°F, provide afternoon shade to protect them from intense heat. If using full spectrum grow lights indoors (such as a T5 fluorescent light fixture), place seed starter cells at a distance of 2 to 4 inches between the top of the seedlings’ canopy and the fluorescent bulbs for 14 to 16 hours a day.
Continue to keep the starting mix moist but not waterlogged.
Up-potting into Larger Pots:
Up-potting refers to transplanting a young plant or seedling from a smaller container or pot into a larger one. While up-potting most seedling crop varieties into larger pots before transplanting into the garden is beneficial, you can skip this step and directly transplant seedlings from the starter cells into the garden if conditions are favorable (maximum air temperature is less than 86°F). However, keep in mind that young seedlings may be more vulnerable to rain, wind, insects, and animal disturbances. Up-potting into larger pots with nutrient-rich potting mix offers better protection and more time for root development.
When up-potting, carefully extract each seedling using a butter knife to avoid disturbing the roots. Photos by Molly Jameson.
When seedlings develop “true leaves” (the second set of leaves after the initial seedling leaves), it is time to transfer them into larger pots (2″-4″ wide).
To start, fill the larger pots about halfway with pre-moistened, nutrient-rich potting mix designed for vegetables, ensuring good drainage.
After thoroughly watering the small seedlings, carefully extract each from the starter cells, using a butter knife for gentle and precise removal to avoid disturbing the roots.
Being careful not to disturb the roots, place each seedling gently into their halfway-filled pot and add more potting mix until the seedling is secure, standing upright, with all roots covered. There should only be one seedling per pot.
Keep seedlings in a sunny location with more than 6 hours of direct sunlight. If temperatures exceed 85°F, provide afternoon shade to protect them from intense heat. If using full spectrum grow lights indoors (such as a T5 fluorescent light fixture), place seedlings at a distance of 4 to 6 inches between the top of the seedlings’ canopy and the fluorescent bulbs for 12 to 14 hours a day.
Continue to keep the potting soil moist but not waterlogged.
Transplanting into the Garden:
When the time is right, dig a small hole in the garden bed and place the plant, along with the potting mix, in the hole, following the crop-specific spacing requirements. Photo by Molly Jameson.
Once the plants have developed strong roots and reach about the height of their pots, they are ready for transplantation into the garden.
If the plants have been indoors under grow lights, allow them to “harden-off” by gradually exposing them to outdoor conditions for a week. This helps them adjust to wind, direct sunlight, and varying temperatures.
Prepare the garden bed with compost and other soil amendments.
Water the plants thoroughly before carefully removing them from their pots, ensuring minimal disruption to the roots.
For each plant, dig a small hole in the garden bed and place the plant, along with the potting mix, in the hole, following the crop-specific spacing requirements (see Table 1 in the UF/IFAS publication Florida Vegetable Gardening Guide).
Cover the roots and maintain consistent soil moisture, avoiding waterlogging.
In summary, mastering the art of indirect seeding and planting fall vegetables can greatly improve your chance of a successful harvest. From carefully sowing your seeds in starter cells to up-potting and ultimately transplanting into your garden, each step is a vital component of the process. So, roll up your sleeves, get your hands dirty, and witness your fall garden flourish. Happy gardening!

You’re in the right hands if you want to grow pumpkins in Florida. While growing pumpkins can be tricky in Florida’s hot and humid climate, you can successfully grow Sunshine State pumpkins with the proper planning and care. Pumpkin is a popular vegetable in the cucurbit family. It shares this family with members of summer and winter squash. The pumpkin varieties differ from those called squashes by having coarser, more intensely flavored flesh and rinds that are softer at maturity than the winter squashes but harder than the summer squashes. Pumpkins refers to certain varieties of C. pepo L., C. moschata Duch. ex Poir., C. mixta Pang., and C. maxima Duch. Local tradition and common usage may dictate that a particular variety is called a squash in one area of the country and a pumpkin in another.
Pumpkin Varieties Choosing the right pumpkin variety is a major decision when growing pumpkins in Florida. Not all pumpkin varieties are suited to Florida’s warm and humid climate. Seminole Pumpkin is a native pumpkin variety well-suited to the state’s warm and humid environment. Traditionally grown by the Calusa, Creek, and Miccosukee peoples, Seminole pumpkins remain one of the tastiest and most reliable for Florida gardens. Seminole pumpkins are known for their hardiness and resistance to disease and pests. The Big Max variety is known for producing giant pumpkins that can weigh up to 100 pounds or more. Big Max pumpkins do well in Florida’s warm climate but may require extra care to prevent pests and diseases. The Jack-o-Lantern variety is the classic Halloween pumpkin for carving and decorating. Look for types suited to warm climates, such as “Funny Face” and “Big Moon.” The Pie Pumpkin variety is best used for cooking. If you plan to use your pumpkins for cooking, look for pie pumpkin varieties such as “Small Sugar” and “Early July.” These pumpkins are smaller and sweeter than carving pumpkins and are ideal for making pies, bread, and other baked goods.
Planting
Most pumpkin varieties need around four months to reach maturity. Pumpkins should be seeded by early July to be ready for Halloween. Spring pumpkins planted in March or April can be stored for use in October and November (though long storage is difficult in Florida). Early August seeding provides a fall crop for late November. Choose a sunny spot with well-drained soil for your pumpkin patch. Pumpkins can be grown in small gardens or containers if you need more space. Plant your pumpkin seeds about 1 inch deep and should be placed 6 feet in either direction, except for the bush types. Plant 3-4 seeds per hill, then thin when the plants are 2-4 inches tall.

Maintenance
Once your pumpkin seeds have sprouted, it’s time to start caring for your plants. Pumpkins need consistent moisture to grow, so be sure to water them regularly. Aim to give your plants about 1-2 inches of water per week. Water thoroughly after planting to help the seeds settle in. Climbing varieties like Seminole can be trellised for more space while using slings to support larger fruits. Use a balanced fertilizer to help your pumpkins grow strong and healthy. Apply the fertilizer according to the package instructions. Pumpkins do well with large amounts of compost. Place compost under each hill before seeding. Side dress with a handful every three weeks or as needed. Keep an eye out for pests such as squash bugs and cucumber beetles, which can damage your plants. If you notice any signs of pests or disease, treat your plants with a pesticide or fungicide as needed.

Fruiting
Like other cucurbits, pumpkins need bees for pollination to produce fruit. Bees are the primary pollinators for pumpkins, so make sure to plant flowers and other plants that attract bees to your garden. Each plant holds male and female flowers, and knowing the difference between them is essential. Male flowers have a long, thin stem and no fruit behind the flower. Female flowers have a swollen, bulbous base that will eventually become pumpkins. It’s essential to have a good balance of male and female flowers to ensure a proper fruit set. If large-size fruits are desired, keep only two fruits on the vine. Once two fruits are the size of baseballs, remove all others as they form.
Harvest and Storage
Pumpkins are ready to harvest when the skin is hard, and the stem is dry and brown. Cut the stem about 2 inches above the pumpkin. After harvesting, allow your pumpkins to cure in a cool, dry place for 10-14 days. Curing helps the skin to harden and protect the pumpkin from pests and diseases. Once your pumpkins are cured, store them in a cool, dry place with good air circulation. Avoid storing them on concrete or damp surfaces, which can cause them to rot. Pumpkins keep for a few weeks, but long-term storage of 1–4 months is challenging in Florida. Store them in a dry (70% RH) and cool (50–60°F) place where possible.
