Thanks to everyone that made our Mill Creek Drive Extreme Cleanup a success! On Saturday, April 18th for Earth Month, Mill Creek Towne Garden Club partnered with Rock Creek Conservancy and Montgomery Parks to help clean up Mill Creek Stream in our 2026 Extreme Cleanup! All in all, fourteen bags were filled, and eleven people participated. Our volunteers enjoyed the spring weather and the flora and fauna near the creek. They saw a box turtle, Virginia Spring Beauties, and Intermediate Wood Ferns, a reminder of why we want to keep our waters and parks clean! Thanks to our neighbors, Friends of Rock Creek Conservancy, and garden club friends who volunteered to make this project a success! Some people travelled here from as far as DC! After cleaning up, several garden club members weeded around the blooming pink dogwood. Here are photos from our Extreme Cleanup. Hope you can join us next year to continue making this a successful venture to help keep our water clean!
Next Saturday, April 25th from 8am to 12noon, we will be having a Plant & Yard Sale. This is our annual fundraiser to help fund our year-round projects including maintaining the Mill Creek Towne entrances and provide garden-related programs. We hope to see you then!

In weekly posts on MD HGIC’s blog, learn about pollinator conservation, growing native plants and food, and how to solve plant pest and disease problems.
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. Bring your plant samples and questions to one of these locations in Montgomery County, MD (see link below to find a location near you):
UMD Home and Garden Information Center: Ask a Master Gardener
Do you have a gardening question? Our Certified Professional Horticulturists, faculty, and Master Gardener Volunteers are ready to answer – year-round!
See below to ask a master gardener a question on the UMD Extension website:
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
Hardy spring bulbs begin to emerge (crocus, snowdrops, daffodils, tulips).
After spring bulbs bloom, let leaves turn yellow and die before trimming.
Transplant spring flowering bulbs after flowering.
Begin hardening off hardier transplants. Sow seeds outdoors of hardier annuals.
Do not set out seedlings or tender annuals until after Mother’s Day (traditional last frost-free date for our entire area).
Deadhead pansies.
Start some more seeds – especially try flowering annuals like impatiens, marigolds, nasturtium, and petunias.
Transplant seedlings into individual 3″ – 4″ pots when crowded.
Ensure new seedlings do not dry out by installing a drip-irrigation system.
Pinch out growing tips of leggy seedlings.
Fertilize summer flowering bulbs.
Cut back and clear out the last of your perennial beds.
Divide perennials.
Edge garden beds.
Mulch beds with a light hand.
Cut your Daffodils for indoor bouquets, but do not combine them with other flowers in one vase. They give off a toxic substance that may kill your other blooms off prematurely.
Buy or check on your stored summer bulbs (such as dahlias and caladiums). Pot them and start to water, if you want to give them an early start on the season.
Hand-pull visible weeds to avoid disturbing newly formed roots.
Plant and prune roses.
Look for evidence of pest or fungal disease throughout your garden.
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.
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: deer, scale, and voles.
Diseases to watch for: Phomopsis and Kabatina of Juniper, Diplodia tip blight of 2 & 3 needled pines.
Keep all transplants watered deeply for 2 – 3 weeks.
Harden off cool season transplants. Plant asparagus.
Plant cool season transplants on the second week in April.
Gently clean up the garden, add 1 inch of compost.
Build a raised bed for vegetables. Add lots of manure and compost.
Plant cool-season crops (potatoes, lettuce, peas, root crops, and cole crops, including spinach, kale).
Make compost tea and use on seedlings.
Turn over cover crop when soil has warmed enough and is not too wet.
Fertilize established asparagus, tree, bramble fruits, and strawberries.
Start herbs from seed or cuttings.
Divide perennials and herbs.
Sow greens indoors or outdoors in a cold frame. Remove cover to allow for pollinating once they set flowers.
Put up trellises and teepees for peas and beans to climb on.
Clean and organize the garden shed.
Till and add organic matter to annual/vegetable beds.
Start seeds for: tomatoes, eggplants, and pepper inside.
Prune stone fruit trees like cherries, plums, and peaches.
Clean out your cold frame or build a new one.
Collect large plastic soda bottles to use as cloches. (A cloche is a clear, bell-shaped cover used to protect tender plants from frost.)
Direct-sow early, cool-season crops as soon as ground soil can be worked. Good choices are beans, corn, peas, lettuces, mustards, onion sets, kale, and cabbages.
Cut perennials and over-wintering ornamental grasses to 2-inches above ground.
Control wild onions in warm season turf with broadleaf weed control.
To control crabgrass, apply pre-emergent herbicide to lawn (when forsythia blooms drop).
Fertilize when green is showing.
Mow high to reduce weeds and stress: Fescue and Bluegrass: 3″ – 3 1/2″
Do soil preparation – add lime, compost, etc. as needed.
Some alternatives to de-icing salts include sand, beet juice sugars, light gravel (grit), or non-clumping kitty litter. Using de-icing salts around driveways and sidewalks can harm your garden plants and turf.
Clean yard of leaves and other debris.
Mulch bare areas.
Check and tune-up power equipment (mowers and trimmers).
Apply grub control to your lawn.
Sharpen your lawnmower blade.
Check and tune-up power equipment (mowers and trimmers).
Turn your compost pile.
Diseases to watch for: brown patch, and red thread

Appalachian Ethnobotany and the Potential for New Horticultural Crops
Dr. Eric Burkhart is a botanist, ethnobotanist, and agroforester in the Department of Ecosystem Science and Management at Penn State. He holds degrees in Botany/Ethnobotany (B.A, Idaho State University), Horticulture (M.S., Penn State University), and Forest Resources (Ph.D., Penn State University). His research and teaching program focuses on wild plant stewardship and agroforestry crop development in Appalachia and the Caribbean. Burkgart will talk about the Appalachian region of the eastern United States, which includes most of Pennsylvania, and is a rich repository of temperate plant biodiversity. In this presentation, Dr. Burkhart will share examples of his work with culinary and medicinal crop development using native Appalachian forest species, and discuss some of the conservation, restoration, and economic opportunities associated with these efforts.
