What to do in your garden in the summer
- Run your irrigation only when we don’t get regular rains. Remember: Twice a week for 45 to 60 minutes is best for your plants, grass, and water conservation. And don’t forget to shut off your irrigation system when it does rain, to save water and avoid problems with fungus. Know and heed the watering restrictions.
- Water early in the morning when possible; this is when plants and lawns absorb the most water.
- Bugs love this hot and humid weather, so be sure to walk through your garden regularly to check for insect and disease damage. But remember, there are many beneficial insects, so be sure to know your insects before spraying. Use insecticidal soaps and horticultural oils whenever possible; they’re safer for you and for the environment. Thuricide and dipel are the best control for caterpillars—but keep in mind that many caterpillars turn into butterflies!
- Help prevent mosquito breeding by emptying any containers of standing water, which is where mosquitoes like to lay their eggs.
- Weeds thrive at this time of year, too. Doing a little weeding more often sure beats the monster job you’ll have if you ignore weeds altogether right now. It’s much easier to pull weeds when the ground is moist—so early evening, after the daily showers, is a great time to get out and weed a bed.
- Mulch your gardens with 2 to 3 inches of sustainable mulch (meleleuca, pine bark, or recycled red mulch), to keep moisture in and weeds out.
- Prune dead and weak branches from trees and shrubs to prevent damage to your home during high winds.
- Lightly prune tropical shrubs—such as hibiscus, oleander, ixora, and bougainvillea—throughout the summer to keep them lush and colorful. In August, prune poinsettias one last time to promote winter blooming. Cut back one-third of the growth on both your potted poinsettias and those in the landscape. It’s a good time to fertilize them, too.
- Time-released fertilizers (such as osmocote or dynamite) and organic-based fertilizers (such as Espoma) are the best for summer feeding, since they present little risk of root burn. Feed your palm trees with Harrell’s 11-4-11, a slow-release fertilizer that contains all the necessary minor elements that palms need.
- Sooty mold may become a problem on your citrus, gardenias, and ixoras. This is an indication that there are insects present (most likely aphids, mealy bugs, or mites). The best control is a horticultural oil spray such as All-season Oil Spray or Organacide. If you see ladybugs in your yard you’ve got the best insect control possible—they’ll take care of most of your populations of aphids, mites, and mealy bugs.
- Avocados ripen to taste after they are picked. Watch your fruit and pick when they reach a good size but are still hard; they will soften and come to taste indoors.
- Bananas thrive on nitrogen; sprinkle grass clippings around the base of banana trees to give them a boost.
- Herbs and vegetables are best grown in pots this time of year, since you can regulate the amount of water and sun they get. Herbs and vegetables to plant in June include: basil, black-eyed peas, cherry tomatoes, okra, oregano, parsley, hot peppers, rosemary, and thyme. Vegetable and herbs to plant in July include: basil, black-eyed peas, chives, dill, and malabar. And in August many herbs can be planted in your garden and in pots—including dill, fennel, mint, parsley, rosemary, and thyme. September will be the month to plant veggies, so you can start to prepare your garden in August.
- Annuals and perennials to plant in June include: alternanthera, begonias, bush daisy, buttercup, coleus, dune sunflowers, gaillardias, gazania daisy, gaura, pentas, porterweed, salvias, and vincas. Flowers to plant in July include: coleus, begonias, purslane, vinca, pentas, lantana, blue wonder, bulbine, torenia, cuphea, salvia, gaillardia, caladiums, and impatiens. Annuals and perennials for your August garden include: alternanthera, begonias, bulbine, buttercup, coleus, jacobinia, lantana, lysimachia, pentas, persian shield, shrimp plant, sweet potato, and vinca.
Frequently asked questions at Rockledge Gardens
Q. Is it safe to use reclaimed water on my vegetable garden and fruit trees?
A. Here’s the answer from the Rockledge Wastewater
Department:
1. Irrigation of edible crops that will be peeled, skinned, cooked or thermally
processed before consumption is allowed. Direct contact of the reclaimed water
with such edible crops is allowed.
2. Irrigation of tobacco or citrus is allowed.
Direct contact of the reclaimed water with tobacco or citrus is allowed, including
citrus used for fresh table fruit, processing into concentrate, or other purposes.
3. Irrigation of edible crops that will not be peeled, skinned, cooked, or
thermally processed before consumption is allowed if an indirect application
method that will preclude direct contact with the reclaimed water (such as
ridge and furrow irrigation, drip irrigation, or a subsurface distribution
system) is used.
4. Irrigation of edible crops that will not be peeled, skinned, cooked or thermally
processed before consumption using an application method that allows for direct
contact of the reclaimed water on the crop is prohibited.
Q. What is that black stuff on the leaves of my gardenia (or citrus, shrubs, etc.)?
A. That’s likely to be sooty mold — a black, powdery-looking substance that grows on the secretion of insects (known as “honeydew”). This secretion can be left by aphids, mealy bugs or scale and the cure is to control the insect. If you don’t see the insect on the affected plant, take a look above the plant as it could be that the insects are present on a plant above. Treat the infested plant with a horticultural oil spray, such as All-Season Oil Spray or Organacide or Insectidical Soap.
Q. Should I fertilize when I first plant?
A. It really depends on what you plan to fertilize with. Synthetic granular fertilizers can cause root burn to new transplants. A natural, slow-released fertilizer, such as Espoma brand, can be used with success at the time of planting. “Dynamite” is also safe to use at planting time.
Q. Why are my palm fronds yellowing and looking “frizzy”?
A. Palms are very heavy feeders, especially in our sandy Florida soils. It’s important to put them on a regular fertilizing schedule of every two months if you’re using a granular fertilizer. We recommend Leonard’s 11-4-11, since it’s a slow-released fertilizer with all of the micro-nutrients that palms require. Sierra blend Osmocote is also quite effective on palms and lasts up to six months.
Q. What is the best time of year to grow vegetables in Florida?
A. We have two main planting seasons for veggies in Florida — fall and spring. Most vegetables thrive during these months. There are also several cool-season veggies that carry through the winter, including lettuce, cabbage, broccoli, cauliflower, and many herbs. One of the most important factors in good crop production is the addition of plenty of organic matter (such as compost or cow manure) at the time of planting.
Q. How far apart should I plant my plants?
A. Spacing of plants should be determined by the mature growth of the particular plant, as well as the effect that you are trying to obtain. If you are aiming for solid coverage, such as in a hedge, most shrubs should be planted 3 to 4 feet apart. Annuals and perennials can be planted much closer to give a full, solid mass of color (12 to 18 inches apart). Trees, on the other hand, need a lot of room for root development and canopy growth. Depending on the type of tree, a general rule would be approximately 20 feet apart. Keep in mind that crowded plants, including rose bushes, are more likely to develop insect and disease problems.
Q. One of my queen palms has died rather suddenly. The lowest fronds turned brown first and within a few weeks the entire palm was dead. What killed it, and what can I do to keep my other palms healthy?
A. The symptoms you describe are those of a new disease called “Fusarium decline.” This is a fungus disease that kills primarily queen palms, but occasionally also kills Washingtonia palms. There is no chemical cure or prevention for this disease; infected palms always die. Since this is a new disease there is still much about it that is unknown, such as how it is spread. The current recommendations of the University of Florida scientists who are studying this disease are: Do not plant another palm, especially a queen palm, where one has died. In addition, after pruning a palm, especially queen palm, sterilize your pruning tools by soaking them in a 25% bleach solution for 5 minutes before pruning the next palm. Remove dead palms as quickly and completely as possible.
