October is an ideal time to plant deciduous trees, shrubs, and roses: The cool weather encourages plants to root quickly and the soil is generally easier to work since it's not as cold and mucky as it can be in the spring.
Continue to withhold water from both evergreen and deciduous trees in the first part of October, which will help prepare them for winter. Resume watering late in October, after the deciduous trees have dropped their leaves. In zones four and five, plant spring bulbs. Continue to divide perennials as needed.
Q: When is the best time to cut back in the fall? A: “When they start to look too ratty for you and before the fresh new growth begins,” says Sarah. For plants that are frost-sensitive, wait until after the plants have gone through several hard frosts to ensure they're dormant before cutting back.
It's important to cut back foliage in the fall to protect flowering plants from disease and give them a clean start for regrowth as winter starts to turn into spring. However, there are some plants you can keep around through the winter since they benefit wildlife and still offer visual interest for your home.
Compost, a crumbly soil-like material, is alive with worms and beneficial fungi and bacteria. It enriches soils, provides nutrients and increases the soil's ability to hold moisture. Several inches of compost can be piled on top of vegetable beds in autumn. Worms and other organisms will slowly work it into the soil.
Soil testing, removing plant material and adding organic mulches, compost and cover crops are all smart gardening techniques for fall cleanup. Use shredded leaves raked from your lawn to cover vegetable gardens or beds.
Also, do not cut back hardy perennials like garden mums (Chrysanthemum spp.), anise hyssop (Agastache foeniculum), red-hot poker (Kniphofia uvaria), and Montauk daisy (Nipponanthemum nipponicum). Leave the foliage. It's important to protect the root crowns over winter.
By not cutting back the statuesque achilleas, eryngiums, perennial astilbes, sedums, alliums and many ornamental grasses, you can enjoy their structure against a winter sky. The sight of their stems silvered with frost adds a whole new level of interest to the garden.
You can still expect some warm weather during October, so keep watering the garden until the fall and winter rains begin. As temperatures drop, less water is needed for plants. Check your soil periodically by digging gently into the soil next to the root, about 6 inches down (deeper for bigger plants).
Fall is the best time to start a new garden.
Consider adding some lyme or fertilizer based on a soil test of your new spot to make sure spring starts off on the right foot.
Fall Feeding for Fertile Fields Fall Fertilization of your shrubs, garden and plants leads to a beautiful, healthy spring garden — it's the ideal time for feeding if you do it right.
On other edible crops, fresh manure applications should be made at least three months prior to harvest. With just a four month or so growing season, this means you should only apply fresh manure in the fall; not in the spring or during the growing season to any area that is or will be planted with food crops.
A constant, fresh supply of organic matter is necessary to keep it growing healthy. While routinely adding an extra layer of topsoil to your lawn can be helpful, fall is the most opportune time to do so. This is because the winter can be a particularly difficult time for the plant life on your property.
Leaving the garden intact for the winter means you'll get a jump start on controlling pests in the spring. Skipping a fall gardening clean up is one important way to help these beneficial insects. Ladybug larvae, such as this one, are voracious predators of many garden pests, including the aphids in this photo.
But when should hostas be cut back? Hostas should be cut back in late fall. Healthy hosta leaves can be left on the plant in early fall to capture much-needed energy, but all leaves should be trimmed off after the first frost to deter slugs and other pests from making your hosta their winter home.
As a general rule, hostas should be cut back in the late fall. Start with leaves that have wilted or turned brown. Healthy leaves can stay a bit longer to help the roots store needed energy. If 25% or more of the hostas is dying, you will know it is time to cut it back.
When it comes to evergreen herbs, which include rosemary, thyme, and sage, you only need to prune about once a year, either in early spring or fall. The three fastest growing herbs are mint, basil, and dill.
