Plant Clinics are held at several sites in the county on a weekly basis and at special events such as garden festivals and the county fair. Regularly scheduled Plant Clinics are located at public libraries and farmers’ markets throughout the county as well as at the Audubon Naturalist Society in Chevy Chase. There are also clinics three days per week at Brookside Gardens. The busiest season is April through September, but some clinics are open year-round.

Maryland’s Best Native Plant Program
The Maryland Department of Agriculture (MDA) in partnership with University of Maryland Extension, the Department of Natural Resources, and the Maryland Native Plant Society is proud to introduce the MDA’s Maryland’s Best Native Plant Program.
This program aims to bring education, awareness, and recognition to consumers and producers about the importance of native plants by:
recognizing retailers, wholesalers, and growers who are selling native plants via a tiered (bronze, silver, gold), voluntary certification program, and helping consumers know where to buy native plants
providing marketing materials- including a MD Native Plant logo- to help consumers identify what’s native to Maryland
Don’t fertilize plants that slow down in heat, but keep them watered.
Take cuttings from coleus and begonias to propagate and over-winter indoors.
Plant hardy mums and fall season annuals.
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.
Your summer annuals will be reviving, now with cooler temps and some rain. Cut back any ragged growth and give them some fertilizer. They should put on a good show until the first hard frost.
Start shopping for spring bulbs.
Divide and transplant perennials – in particular, peony and iris.
Preserve dry flowers for display in the fall.
Renew your container plantings, which may be looking a bit ragged at this point. Pinch back overgrown plants. Pull out any spent ones and pop in some substitute annuals or mums. Keep them well-watered and add a little liquid fertilizer every few weeks to keep them going through early autumn.
Stake and tie-up any tall-growing perennials such as phlox or delphiniums.
Start collecting plant seeds for next year and for trading.
Put out slug traps around your vulnerable hostas.
Feed your roses and new plantings with slow-release fertilizer sparingly.
Tie-up clematis and other fast-growing climbing vines.
Hose off aphids, white flies, or spider mites on your roses or other perennials.
Check pots and containers daily for water needs.
Look for evidence of pest or fungal disease throughout your garden.
Weed and weed some more.
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 for powdery mildew. If seen, prune back perennials to create needed circulation. Discard properly (i.e., not in your compost bin).
Rake up weeds and their seedlings, especially look for fast-growing vines such as honeysuckle, autumn clematis, bittersweet, wild grape, Virginia creeper, and poison ivy.
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.
If your conifers start shedding their needles or your spring bulb foliage starts peeking out of the ground, don’t worry. This is normal for our autumn cycle.
Take cuttings from azaleas, boxwoods, and camellias to start new plants.
Thin out small trees and cut off any suckering branches growing from the bottom root ball.
Hold off on planting new trees and shrubs until the summer heat has passed.
Transplant trees and shrubs.
Plant evergreens for winter interest.
Prune foundation shrubs and trees to be no closer than 1 foot from the house.
Contact a certified arborist to have your trees’ health inspected.
Directly after blooming, prune flowering shrubs and vines.
Prune boxwoods.
Get a soil test.
Prune long shoots on shrubs to keep plant neat looking.
If you must mulch: Remove old mulch, then add 2″ – 3″ shredded pine or pine needles, keeping 3″ away from trunk.
Clean your gutters.
Do not fertilize newly planted or transplanted plants the first year.
Check often and water newly planted trees if they don’t pass the finger test (stick your finger deep into soil – dry? Water!)
Prune broken, dead, diseased, or damaged branches.
Keep an eye out for bark damage from rabbits or deer.
Check for vole problems and set out traps.
Spray broadleaf evergreens with anti-desiccant to prevent dehydration.
Look out for any Poison Ivy vines, which will turn crimson in the fall and be easy to distinguish from other vines.
Weed – especially look for fast-growing vines such as honeysuckle, autumn clematis, bittersweet, wild grape, Virginia creeper, and poison ivy. Remove Ivy, Pachysandra, and other vine-like groundcover from under shrubs.
Mulch or compost healthy leaves.
Continue to remove fallen, diseased leaves.
Put diseased leaves, pesticide-laden grass clippings and weed seeds in your trash — not your compost pile.
Turn your compost pile weekly and don’t let it dry out. Work compost into your planting beds.
Apply scale and dormant oil treatment before dormancy breaks to decrease pest infestations.
Remove dead and dying trees.
Pests to watch for: aphids, azalea lacebug, bagworms, caterpillars, deer, gypsy moths, Japanese beetles, leafminers, sawfly, scale, spidermites, voles, and webworms.
Diseases to watch for: Apple scab, Cedar-apple, hawthorn or quince rust, Verticillium wilt, Oak leaf blister.
Keep an eye out for the first frost date. In Zone 6, it is expected between September 30 and October 30. In Zone 7, it is predicted to be between October 15 and November 15.
Continue planting cool-season vegetables; plant garlic now through the end of October.
This is a good time to have your vegetable garden and landscape soils tested.
Pick apples at your local pick-your-own farm or visit a local farmer’s market.
Watch your pumpkins/squash. Harvest them when their rinds are dull and hard.
Plant cover crops in vegetable gardens and annual beds (for example, rye, clover, hairy vetch, and winter peas).
Pot up rosemary and chives for over-wintering indoors.
Pick mature tomatoes and peppers to ripen on your window sills.
Remove rotting fruits from fruit trees and compost them.
Harvest leaves of herbs used in cooking (rosemary, basil, sage) in early morning, for best flavor.
Bring in houseplants if you took them out for the summer.
Begin conditioning Christmas cactus and poinsettias to get them ready for the upcoming holiday season.
Bring Amarylis indoors before a hard freeze. Repot every other year at this time. Store in a cool, dark place and do not water until flower buds or leaves emerge.
Re-pot the houseplants you’ve moved outdoors for the summer.
Re-pot root-bound houseplants and start fertilizing them when new growth begins.
Mist indoor plants and set up pebble trays to increase humidity.
Deadhead flowering plants.
Scan houseplants for insect activity.
Maintain moisture in pots, but do not overwater!
Give your houseplants a quarter turn every few weeks.
Keep all houseplants out of drafts and away from heat vents.
Keep succulents and cacti on the dry side.
Check on your container plants daily and keep them well-watered.
Remove old leaves, damaged stems.
Dust your houseplants with a slightly damp cloth to prevent dust and film build-up.
Pests to watch for: aphids, spider mites, mealybug, scale, stinkbugs, and whitefly.

Sept 2nd—Saving Ash for Future Forest
Wednesday, Sept 2nd
12pm – 1pm EST
Ash trees in North America face a severe threat from the emerald ash borer (EAB), now present in 38 states. Ash species are vital to many forest ecosystems, including black ash (Fraxinus nigra), which holds cultural significance for numerous Indigenous communities. Cornell Botanic Gardens is working to conserve and restore ash to New York Forests by propagating individuals showing natural resistance to EAB. Todd Bitner, Director of Natural Areas, will highlight ash conservation efforts and ways citizen scientists can help restore ash to our forests.
If you need a reasonable accommodation to participate in this event, please contact Lisa Kuder at lkuder@umd.edu two weeks prior to the webinar.
