Sustainable Gardening for Renters

When: April 10th from 11 am to 1 pm

Hosted by: Ecology Center

Are you a renter who wants to grow a garden? No yard? No extra money? No problem!  Most renters, especially if they’re not planning a stay, prefer not to spend too much time or money fixing up someone else’s property.

But the benefits of home gardening, including lowering your grocery bills, making healthier eating easier and combatting climate change and the mind benefits of planting should not be an obstacle to renters. In this hands-on workshop, Lori “Compost Gal” Caldwell, a long-time renter herself, will help you navigate small spaces and the ways to grow food as a renter. She will demonstrate creative solutions and cover topics such as:

  • Container gardening indoors and outside
  • Vertical Gardening (hanging pots and peats, pallets & trellises
  • From concrete to food: creating temporary raised beds
  • Plant selection, crop rotation and maintaining fertility
  • Working with your landlord and landlord incentives for lawn conversion
  • Free/low cost resources
  • Reuse options
  • Taking your garden with you

Do you have a burning question you’ve always wanted to ask a landscape design or maintenance expert? Have a question about a specific plant or landscape challenge where nothing seems to work no matter what you do? Styled after NPR’s long-running and popular “Car Talk” program and continued from last year's Water Showcase, this session is designed to address landscape, garden, and plant questions from attendees. We will also include a guest panelist, a garden-based puzzler, and a “stump the chumps” segment. If you are unfamiliar with “Car Talk”, go here: Because we can substantiate questions with visuals, participants can submit photographs, diagrams, and other descriptive information related to your inquiry.
