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:

    • Control invasive plants

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.

Below are resources for you to learn more and help you get started. Happy growing!

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.
