Rain Barrels and Compost Bins: Your Spring Sustainability Upgrade (and Where to Get Them Locally)

Spring is the perfect time to think about working with nature rather than against it — and two of the simplest tools for doing that are a rain barrel and a compost bin. Better yet, if you live in Baltimore, Howard, or Harford County, your local government is making it easier (and cheaper) than ever to get started.

Why Bother?
Rainwater is free from chlorine and other water treatment chemicals, making it ideal for gardens. Rain barrels also help reduce water pollution caused by stormwater runoff. A single moderate rainstorm can fill a barrel quickly — a 1,000 square foot roof can shed up to 600 gallons in just one inch of rain giving you a free, natural water source for your lawn, garden, and potted plants all season long.

On the composting side, decomposition converts food scraps and yard materials into a rich soil amendment called humus, which returns nutrients like phosphorus, potassium, and nitrogen to the soil. Compost also helps increase water retention in sandy soils and improves drainage in heavy clay soils.

Baltimore County
Baltimore County's Compost Bin and Rain Barrel Sale runs from April 1 through June 5, 2026, and all purchases must be made online in advance. All pre-ordered items must be picked up on Saturday, June 13, 2026, between 9:00 AM and 2:00 PM at CCBC Essex, 7201 Rossville Blvd, Baltimore, MD 21237. The best part? The sale is not limited to Baltimore County residents, so neighbors are welcome too. Visit baltimorecountymd.gov for pricing and to place your order.

Howard County Residents
Howard County runs an annual rain barrel giveaway program. The county gives away 40 rain barrels at GreenFest each April, and residents must complete an online training and sign up in advance to receive one. If you missed GreenFest, there is also a rain barrel giveaway held on Saturdays in May at the gazebo at the Alpha Ridge Landfill, with signup opening April 16th, 2026 at 9:00 AM. Visit howardcountymd.gov/public-works/rain-barrel for the signup link and training when it goes live.

Harford County Residents
Harford County's Ag-Stravaganza event on Saturday, April 25, 2026 (10 AM – 3 PM) at Poplar Grove Park, 3519 Conowingo Road, Street, MD will include a rain barrel and compost bin raffle, free mulch and compost (bring your own container), a tree planting ceremony, and the chance to meet local agricultural and environmental experts. It's a great outing and a wonderful opportunity to score some free supplies for your spring garden.

The Bottom Line
Rain barrels and compost bins are low-cost, high-impact tools that are good for your wallet and the Chesapeake Bay watershed. Take advantage of what your county is offering this spring!
