The hottest days of the summer are here and you might be thinking, “There is no way something could survive this heat!”. You might also be wondering “What can I do in my landscape?” Well, you are correct – it is hot and there are not many plants that thrive in this type of weather, but the good news is we are at the end of the summer season and there are things we can begin to do to get ready for fall. It’s not too late to get the last of the summer vegetables going such as lima beans, cucumbers, eggplants, and peppers. Many cool season crops can also be planted by seed now and tomatoes will thrive going into the fall season. See Vegetable Gardening in Florida
There are some heat-tolerant annuals like vinca, gaillardia, bulbine, and coleus that can be planted now in the landscape. See Annuals. Any time of the year, even late summer, bulbs like Aztec Lily, Butterfly Lily, Walking Iris, and Spider Lily can be planted. See Bulbs for Florida. Not many herbs do well in our Florida sun this time of year, but Bay Laurel, Ginger, Mexican Tarragon, and Rosemary can be planted as transplants now but not as seeds just yet. See Herbs.
August and late summer is the time of year that you may be seeing damage in your lawns. This could be caused by insects, disease, or irrigation failure. It is important to determine the cause, so the proper remedy is used. Some ways to avoid lawn damage are checking your mower blades regularly and making sure they are sharp. Also only cut the top one third of the blade of grass to not stress it in the heat of the day. It is good practice to test your irrigation clock and have a rain sensor. Some municipalities in north Florida prohibit the application of fertilizer during the summer rainy season from June to September so check with your local extension office.

There are some other maintenance measures you can take in August to help your landscape and prepare for the fall season. If older palm fronds are yellowing, this could indicate a deficiency in magnesium or potassium. Talk to your local agent or visit your local store for an appropriate palm fertilizer. See Palm Nutrition and Fertilization. Are you holding on to those beautiful fall mums or decorative Christmas poinsettias? Now is the time to pinch them back to allow time for buds to set for winter blooms. Finally, it is a good time to deadhead (remove old blooms) and fertilize flowering annuals and perennials. We’ve had substantial rain this summer, so keep in mind that the soil could be lacking nutrients. A soil test can give you data that indicates what you need for the up-and-coming growing season.
Tatsoi is a low-growing green with spoon-shaped, dark-green leaves. Photo by Molly Jameson.
Sweet to the palate, easy to grow, and a delight to watch take shape, tatsoi is a great choice for your fall and winter veggie garden.
Tatsoi is in the cabbage family, species Brassica rapa, and is closely related to another Asian green, bok choy. It originates in Japan, where it has been grown for over 1,500 years.
Tatsoi is an annual with spoon-like dark-green leaves and cream-colored stems that grows low to the ground. It is easy to start from seed, can handle partial shade, and grows relatively fast. It can be eaten raw, like spinach, or it can be lightly cooked to add a pleasantly distinct flavor to stir-fries and soups. It has a surprisingly mild mustard-like taste. It is full of vitamin C, calcium, potassium, folate, and phytonutrients.
Tatsoi takes about 40 to 50 days to reach maturity. Photo by Molly Jameson.
Although it does well in the spring in cooler climates, it does best in fall and winter in Florida and can handle temperatures down to 15°F. It can be directly seeded into the garden and germinates in about five to 15 days. You can seed tatsoi one to three inches apart, but it should be thinned to about eight to 10 inches to reach full size, which takes about 40 to 50 days. Add the baby tatsoi you thin to your dinner salad.
Once thinned, harvest whole mature plants or individual outer leaves. If you find you just can’t get enough, seed more tatsoi every two weeks until the spring, when longer days and warmer temperatures will cause tatsoi to bolt. Bolting is when a plant diverts its resources away from the edible leaves and into the flowering stem for seed production.
For a truly continuous supply, allow your tatsoi to bolt, and it will produce many tiny, thin seed pods. Wait for the plant to dry completely and harvest the seed pods. Carefully open the pods over a plate to be sure to catch all the small round seeds within. Then, simply store the seeds in a dry, cool location, such as your fridge, in an air-tight container. Stored correctly, the seeds will last four to five years.
If you have yet to give tatsoi a position in your garden, give it a try this winter!

You don’t have to huge open spaces to garden. Master Gardener, Muriel Turner shares how she gardens in small spaces in containers or small beds along structures and pathways around her home. She combines herbs, okra, blueberries, and citrus along with ornamental succulent and flowering plants to adorn her home and flavor the meals she prepares for her family and friends.
Veteran Master Gardener, Les Furr shares an idea he and his wife had to hide an ugly debris pile following Hurricane Michael. He planted a temporary sunflower screen to block something ugly with something beautiful. Sunflowers can be planted along a road or fence, and provide a lovely addition to your property. The seed can be saved and frozen to provide beauty to your property year after year.
