Rain Barrel Giveaway

Registration has filled! Upcoming rain barrel giveaways will be available at Alpha Ridge Landfill. Visit the rain barrel webpage for more information.

Howard County residents can help reduce stormwater runoff with the help of a rain barrel – they collect and store runoff from roof downspouts, and this water can be reused for lawns and gardens, reducing the use of potable water.

This year, 40 rain barrels will be given away at Greenfest. Prior registration and online training is required.

Registration opens on April 5th, 2023!


Sports Equipment Donation

Slow Art Walk @ 11:00am

Slow Art Day 2023

On average, many people look at a work of art for no more than 15-30 seconds, but slowing down can create deeper understanding of the works and more meaningful, richer personal experiences.

Take a slow art walk of HCC's campus during GreenFest! The walk will begin at 11:00am at the BLM sculpture located at the northeast entrance to the SET Building.

Master Gardener Program

Master Gardeners

Howard County Master Gardeners are volunteers, trained by the university, providing horticultural education services to individuals, groups, and communities including government agencies, neighborhood associations, non-profit organizations, historic sites, schools and youth groups, senior citizens and garden clubs. Master Gardener programs and services are available free of charge to all Howard County residents and community groups.  For more information on our services or becoming a Master Gardener check out our website.


Our mission is to educate residents about landscape practices that protect the Chesapeake Bay and our local waterways.  By changing a few simple practices, together we can help keep our Maryland water healthy. 

Are you Bay-Wise?  Test your knowledge of these Bay-Wise principles by using the Bay-Wise Yardstick to see how you measure up. 

  • Controlling Storm water Runoff
  • Encouraging Wildlife
  • Protecting the Waterfront
  • Mowing properly and Watering Efficiently
  • Managing Yard Pests
  • Mulching and Recycling
  • Fertilizing
  • Planting Wisely

Home consultations to assist homeowners with their landscaping problems will resume once the threat from the Corona virus is past. In the meantime, please refer to the resources on our webpage.

Ask a Master Gardener

Ask a Master Gardener-Plant Clinic is a program where Master Gardener volunteers, in conjunction with the University of Maryland Extension, provide information to home gardeners at the county libraries and other events throughout the county.  


Compost is a dark and crumbly material produced by the natural decomposition of leaves, kitchen food scraps, and other organic materials. Why compost at home?

  • Reduces waste: Yard and food waste that can be composted make up around 25% or more of trash to landfills.
  • Improves soil: Compost helps break up clay and attracts earthworms that aerate soil.
  • Retains moisture: Slows run-off from rain by holding three times its weight in water. Incorporate compost in the soil so you water less.
  • Reduces need for fertilizer: Compost provides nutrients for your plants, trees, lawns and shrubs.

How you can help pollinators:

  • Provide food – Plant natives
  • Provide water sources (and puddling areas for butterflies)
  • Provide shelter
  • Safeguard pollinator habitat
    • Control invasive plants
    • Reduce pesticide and herbicide use
Grow It! Eat It!

The Grow It! Eat It! campaign is a joint venture between The Maryland Master Gardener program and the Home and Garden Information Center - to provide education and encourage Marylanders to learn how to start and maintain successful food gardens.

Spring is here and it’s the perfect time to start a home garden! With the current COVID-19 crisis we are all a bit stressed and could really use the therapeutic benefits and productivity of food gardening. Here are just few of the many benefits to growing your own food:

  • Fresher & More Nutritious - Fruits and vegetables that ripen naturally in the garden and are consumed within days of harvest have more nutrients than store-bought vegetables.
  • Save Money - A seed packet of basil costs as little as $.99 and contains hundreds of seeds. One small bunch of basil in the grocery store can cost 3x as much.
  • Greater Variety - Food gardening provides the opportunity to try plants and varieties that aren’t available in markets.
  • Less Environmental Impact - We minimize our food's environmental impact when we grow it at home.
  • No Pesticides – Growing food at home means you have total control of how the plant is grown and cared for. It’s a simple way to guarantee your food is organic when you don’t use pesticides.


Watershed Stewards Academy

The Howard County Watershed Stewards Academy is a cooperative effort of the University of Maryland Extension and Howard County to increase the number and diversity of trained volunteers who have the knowledge and skill required to enhance the health of our local streams, rivers, and lakes. Watershed Stewards work with neighbors to provide best storm water management practices.

We are not accepting requests for neighborhood and homeowner inspections while we limit personal contact to help minimize the impact of the Corona virus. We will resume when it is advisable; hopefully soon. Stay safe.

Home and Garden Information Center
