September Gardening Tips

General Gardening Tips

Replace faded summer annuals with chrysanthemums, asters, pansies and other gorgeous fall flowers.

Pick up spring flowering bulbs now for the best selection and plant any time before Christmas. You’ll be glad you did – by taking a little time to plant daffodils, tulips, hyacinths and other favorites this fall, you’ll be welcomed with a burst of beautiful color come spring. We carry a wide array of time-honored favorites and exciting new varieties.

Divide and transplant bearded iris, peonies, daylilies and other spring and summer flowering perennials.

Prune hybrid roses to produce the most fall flowers. Remove any dead or diseased branches. Continue using Bayer Advanced All-In-One Rose & Flower Care, which feeds roses and systemically prevents insects and diseases for six weeks.

Wait until mid-November to prune. If you prune now, it will stimulate new growth, which may not have enough time to sufficiently mature prior to an early freeze.

As the weather cools, begin watering established trees and shrubs less often, but check the soil for moisture at least once a week. If the soil is dry, give your plants a thorough watering. Continue this practice until the ground freezes.

 

Lawns

September is the best month of the year to make your lawn dense, dark green and healthy. Repair bare patches and over seed your existing lawn with grass seed mixtures and fertilize.

If your lawn is suffering because of dense, heavy clay soil, this is a good time to aerate the ground and top dress with compost. This can be done at the same time as seeding and fertilizing.

 

Pest Controls

Use Diatomaceous Earth to control crawling insects, such as cockroaches, ants, slugs, silverfish, earwigs, fleas, spiders, millipedes, centipedes and carpet beetles. Use indoors and outdoors.

Use Round-Up to kill weeds and grasses in brick patios and walks. Stop birds from making a mess on your patio or car by placing our inflatable owls or inflatable snakes in your garden. This also works to protect fruit from bird attacks.

Spray roses with Ortho Rose Pride or Immunox Plus to keep black spot and other problems under control.

Spray for bagworms on arborvitae and other evergreens. Use Sevin or Eight.

Spider mites can be controlled on Alberta spruce, hemlocks and other plants using Bonide Systemic Insect Control or Bayer Advanced 3 in 1 Insect, Disease and Mite Control.

Lacebugs can be controlled on azaleas, andromeda and other plants with Bayer Advanced 12 Month Tree and Shrub Protect and Feed or Bonide Systemic Insect Control.

If necessary, treat dogwoods for borers with Borer Miner Killer.

To treat hemlock woolly adelgid, euonymus scale and other pests, use Bayer Advanced 12 Month Tree and Shrub Protect and Feed or Bonide All Seasons Spray Oil.

Fruit trees should be on a regular spray program!

 

Fruit and Vegetable Gardens

Plant lettuce, cabbage, cauliflower, beets, radishes and other fall crops. Use Sweeney’s Deer Repellent for season-long control to keep deer away from your harvest.

Tips on Applying Weed Killer:

  • Do not apply weed controls on newly seeded areas.
  • Do not apply weed controls on windy days.
  • Do not apply weed controls near or on the edge of waterways.
  • Do not allow children or pets to play on lawns freshly applied with weed controls. It is best to wait one week.
  • Do not apply weed controls when temperatures are above 85 degrees F.
  • Always follow the label directions.

 

Houseplants

Continue to feed houseplants with a good quality indoor plant food, such as r Osmocote (slow-release granular).

If needed, re-pot root bound houseplants to a larger pot. Dragonfly stocks a full line of containers, including terra cotta, wood, concrete, ceramic and plastic. Use Potting Mix when repotting houseplants.
