Flowers and Groundcovers

• Rake up weeds and their seedlings.
• Wait to mulch until ground freezes hard.
• Collect plant seeds for next year’s planting and for trading at the annual Washington Gardener Magazine Seed Exchanges.
• Begin replanting pots with hardy annuals. 
• Take cuttings from coleus and begonias to propagate and over-winter indoors.
• Plant newly purchased plants.
• Continue to deadhead.
• Your summer annuals will be reviving, now with cooler temps and some rain. Cut back any ragged growth and give them fertilizer. They should put on a good show until the first hard frost.
• Remove spent annuals and replace with fall annuals. Water deeply.
• Cut fully yellow lily stalks.
• Fertilized established bulb beds.
• Dig up bulbs from your Gladiolus, Canna, Caladiums, and other tender bulbs; cut off foliage; let dry for a week; and store for the winter.
• Start bulb plantings of early spring bloomers at the end of the month.
• Check your container plants daily and keep them well-watered.
• Gently clean up the garden.
• Water thoroughly, especially if you receive no rain for more than seven days.
• Divide and cut back Bearded Irises and Peonies.
• Divide Hostas and Daylilies.
• Check for black spot on your roses – remove and discard any affected leaves in the trash, never back into your garden or in your compost – apply fungicide with Neem oil every two weeks during the growing season.
• Inspect your garden from powdery mildew. If seen, prune back perennials to create needed circulation. Discard properly (i.e., not in your compost bin).
• Hand-pick Japanese beetles or shake them off over a bucket of dishwater. Early morning is a good time to catch them, while they are still drowsy.
• Weed. Especially look for fast-growing vines such as honeysuckle, autumn clematis, bittersweet, wild grape, Virginia creeper, and poison ivy.
• Pests to watch for: Aphids, spider mites, whiteflies, deer
• Diseases to watch for:  Powdery mildew, Rust
• See UMD’s HGIC Garden Tips for more details.

5 Million Trees Initiative

Maryland’s goal is to plant and maintain 5 million native trees by 2031. There are various ways you can get involved – plant trees and register them — or volunteer! A number of tree-planting assistance programs are available at the municipal, county, and state levels.

THIS is the SUPERPOWER of YOUR KEYSTONE NATIVE PLANTS.

• No exotic plant could ever achieve this.
• Want butterflies? Feed the caterpillars with keystone plants!
• Exotic plants will never support as many different species of caterpillars as the Keystone Natives can.
• Find your keystone native plants here by zip code.

If your zip code doesn’t give you enough information try zip codes of the nearest larger town or city. LINK: https://www.nwf.org/NativePlantFinder/

Trees and Shrubs

• Plant evergreens for a winter interest.
• Fertilize if necessary for the last time.
• Avoid late summer pruning.
• Water slowly and deeply if summer is very dry.

• Keep bird feeders clean and filled.
