GARDENING

Simple steps for reducing your garden's carbon footprint.

Because working the soil, growing beautiful flowers and eating food you raised yourself are so rewarding, gardening's popularity continues to grow [pun intended]. 

 

Try these tips for reducing your garden's carbon footprint, most of which are described in greater detail in the small handbook, The Climate Conscious Gardener:

Compost Your Yard and Food Wastes

Methane is a greenhouse gas.  Composting keeps methane-producing wastes out of the landfill.  Compost adds nutrients to your soil.  Healthier plants better resist pests and diseases.  Compost improves soil texture, even helping to break up clay, so roots can extend deeper.  And because compost encourages worms, it improves soil permeability and aeration.  Learn how to compost here and here.  Or sign up for LCAN network member Louisville Compost Co-op's services.

Fertilize Only As Needed, Using Organics

Synthetic fertilizers are made from fossil fuels, so are a big source of greenhouse gasses.  Use organic fertilizers if your garden needs more than what your compost offers.  Especially if starting a new garden, it's smart to have its soil tested so you'll know how much of which nutrients truly are needed.  The Cooperative Extension Service provides testing for minimal charges.  Be sure to follow directions on how to take a representative sample.

Consider Raised Beds for Small Gardens

Depending on the size of your garden, raised beds may make sense.  If you build them no wider twice the distance you can reach comfortably, you won't cultivate and fertilize paths.  Raised beds can provide a place to sit while sowing and tending plants.  The soil in raised beds warms earlier in the growing season and is less likely to become soggy in wet weather.  You can mound soil or build frames from materials you have or can re-purpose.  Or buy sturdy frames from YouthBuild-Louisville.

Use 2" to 4" of Organic Mulch

If you mulch, you won't have to water nearly as often.  Your plants will be less stressed during dry spells.  Lay up to 4" of organic mulch around plants:  leaves (saved from the previous fall), grass clippings, wood chips, pine straw (needles), manure, newspapers or flattened cardboard.  Use what's local, if not from your yard.

Water Efficiently

Most established plants need 1" of rain per week, though young transplants may need more.  Use a rain gauge (or tuna or cat-food can) to monitor how much rain your garden receives.  (Or query the MSD gauge closest to you.)  When you need to water, do so once weekly.  Use soaker hoses to limit evaporation, and trickle water slowly and deeply. 

Consider No- or Low-Till Gardening

Digging and, worse, double-digging garden beds annually is back-breaking work without a tiller.  With or without mechanical help, tilling releases carbon stored in the soil into the atmosphere.  Why not save your back and the planet by adopting no-till or low-till techniques?  It's one of the best ways to reduce your garden's carbon footprint.  Learn more here.

Consider Native and Heirloom Species

Biodiversity will continue to decline if a handful of seed companies limit what we plant.  Pollinators are critical to a successful garden, and love native species.  Look for native flowers, ferns, shrubs and trees, and heirloom varieties of veggies, fruit, etc.  Find lists of suggested species here and, if you're on Facebook, here.  Too late to order heirloom seeds?  Check your nearest Farmers' Market for native species and heirloom varieties of garden plantsDropseed Nursery offers a wide variety of native grass, flower, vine, tree and shrub species.
