July is a month of anticipation in North Florida, because most of our fall/winter crops are planted in August. There are only a few veggies you can start from seed in July, but there is still time to put larger plants in the ground. You can usually find veggies such as peppers and tomatoes in sizes from 3-inch to 1 gallon pots, or sometimes even larger at nurseries and big box stores.
Time to Start Pumpkins and Cucumbers
Early July (before the 15th) is the time to start your pumpkin. Plant them directly into the ground, because squash family plants do not like to be moved. For the smaller decorative or personal pumpkins, save space by growing them up a strong trellis. This will also keep soil-borne insects from attacking them.
Cucumbers can also be started in July, and again, I would suggest planting directly into the ground and trellising them. You can also wait and plant them in August, but it never hurts to have an early start, so if they don't grow well, you still have time to replant.
Starting Tomatoes for Fall
Tomato seeds should be started indoors now for fall planting. Keep them indoors until they are around 4 weeks old, acclimating them slowly outdoors for a few hours a day. I always start putting mine in shade first, then semi-shade, then morning sun before exposing them to the harsh summer sun. It should take about 2 weeks to acclimate them.
Southern Peas
There is still time for one more planting of Southern peas, also called cowpeas or field peas. There are many varieties of these easy-to-grow nitrogen fixing legumes, so try a few new ones if you have space. If you're growing okra, plant some of the climbing varieties underneath them for nitrogen fixing and free trellising. These are great companion plants for heavy feeders such as eggplant.
Planting from Starts
Eggplant and peppers are best planted from starts if you want a late summer crop; however, you can now start pepper seeds indoors to plant out in the fall. I usually start my bell peppers indoors in July and move them into 3-inch pots once they have their second set of leaves. This will keep them going until you plant them out or move them up to larger pots in August.
Cherry tomatoes will also do well from starts, the bigger the better. I suggest either buying small starts and putting them into containers or buying 1-gallon or larger starts to put directly into the ground.
Watch out for Everglades tomatoes starting to fail in the heat, and be sure to gather seeds, which you can start now for a fall crop. I like to just squirt the seeds out into a 1 gallon pot, where they will come up and start growing again. You don't have to take great pains to get these plants to grow.
Ornamentals to Plant in North Florida in July
There aren't a lot of annuals that will stand being planted or transplanted during the July heat. It's best just to keep your present annuals watered well and look forward to planting more in the fall.
Bulbs of butterfly lily, gladiolus and society garlic can be planted in July.
Preparing the Garden for Fall Planting
Late July is a good time to start preparing the garden for fall planting, especially if you have solarized, planted a cover crop or left it fallow over the summer. Although the heat is oppressive, I usually work very early in the morning or later in the evening (be sure to wear mosquito repellent) to get things done, sometimes just 10 minutes at a time.
Pull weeds and turn more organic matter into the soil. Check the pH and adjust accordingly with whatever amendments are necessary. If you aren't going to plant right away, it's a good idea to place cardboard over the garden to keep weeds from growing back.
July is a tough, hot month for North Florida gardening, but there are still things to plant and things to do, so don't give up on the garden yet!
Happy Gardening!
