September Gardening Calendar

Beets

Let’s get ready for September in preparation to cooler temperatures by fertilizing annuals, perennials, and roses one last time for winter preparation. Check flowerbeds for pooped-out perennials such as Purple Coneflower, Black-Eyed Susan, and Shasta Daisy. Trim dead flower heads and brown leaves for fall.

Fertilize Chrysanthemums and Salvia with a liquid plant food. You will be rewarded with blooms later in the fall.

Chrysanthemums, Pansy, Viola, alyssum, and Snapdragons provide winter color through the spring and should be available by mid-September at garden centers. For a complete list of Fall Color Annuals Click Here For More Information. For spring blooms plant Bluebonnet and Poppy seeds now.

September is a good time to divide and cut back perennials. Check your daylilies, irises, and monkey grass while the weather is still warm.

Are you planning to bring your Tropical Hibiscus in this winter? Place in a sunny window.

Preserve excess Basil leaves by pureeing in a blender with ¼ cup of olive oil or water. Pour the mixture in ice trays and use the cubes in your wintertime Italian dishes.

Spring-flowering bulbs should be on sale. Plan to plant in mid-October or when the weather cools to the 60’s or below.

Start planning where you will place your Tropical Plants that spent the summer outdoors. Trim back, if necessary and inspect for insects. Spray with appropriate insecticide, if needed. I prefer to use horticulture oil on my houseplants. Horticulture oils are environmentally friendly and will give your Houseplants a nice shine along with killing any insects. Check out our selection of Tropical Plants.

Are you planning a fall vegetable garden? Cool weather vegetable starts such as Beets, carrots, radishes, spinach, kale, brussel sprouts, Broccoli, Collards, Cabbage, Tomatoes, Peppers, and Snow Peas are good choices. Don’t have room to plant a fall vegetable garden, but would like to grow your own vegetables? You can grow vegetables in a container. The container should be 16 inches or larger and for excellent success use a potting soil. For more information on Fall Vegetable Gardening Click Here.

The last week in September is the time to replace your mulch under your Roses and Red Tip Photinia to prevent diseases on next year’s leaves. Rake up any fallen leaves before replacing the mulch.

As the weather cools, this is a good time to plant shrubs and trees. When planting in the fall, it provides less stress on the plant and the roots start to get established in the ground. SuperThrive is the recommended concentrated solution of plant vitamins and hormones used to encourage plant and root growth and to revitalize stressed or dying plants. SuperThrive is not a fertilizer and can be mixed with your favorite liquid fertilizer. Dosage recommendation for transplanting or weekly use: ¼ of a teaspoon per gallon of water, or for larger projects 3 ounces to 100 gallons of water. To revitalize stressed or dying plants use: 1 ounce to five gallons of water and water the root zone or drip line. Then water every 3 – 5 days ¼ teaspoon to 1 gallon of water at the root zone or drip line. For bare root roses use: 1 ½ teaspoons per 5 gallons of water and soak for at least 30 minutes. Depending on your plant’s condition you may use weekly or monthly.

During drought or stressful conditions, it is wise to water established shrubs and trees. The recommended rate for trees is 15 gallons of water per each trunk diameter a week. Break up the amount of water to twice a week and use SuperThrive as recommended above.

I found another good additive to mix with water that will help get your new transplanted plants established. It is called Recharge from Real Growers. It’s a professional strength microbial superpack. Recharge helps and promotes stronger plants within 48 hours. I was skeptical, but I tried it and it really does work. That’s why I would recommend it when adding new plants to your landscape. You can mix Superthrive and Recharge together in water for excellent results.

Bermuda grass seed should be planted no later than September 15^th to ensure that the seeds germinate and become established before winter frost.

Brown Patch fungus is more apparent in the fall months. Prevention is the best cure by watering your lawn early in the morning before 10:00 AM or after 4:00 PM.

Mid-September is the last feeding for your lawns. Fertilize your lawn with a winterizer weed and feed to prevent spring-time weeds.
