Learning All Things Compost at the Vaca Valley Garden Club
By Jill Hopkins, Vaca Valley Garden Club
We were excited to bring speaker (and composting expert extraordinaire!) Lori Caldwell to the Vaca Valley Garden Club for their September meeting. Here, club Vice President Jill Hopkins shares about Lori’s talk and the garden club.
Lori Caldwell presents all about compost
At the first regular meeting of the 2025-26 year for the Vaca Valley Garden Club, 54 members and guests were treated to the energy of Lori Caldwell, The “Compost Gal,” on Sept. 10. Lori’s presentation covered a series of compost contrasts for the Garden Club when she spoke of the appropriate Brown/Green Ratio; the difference between Damp and Mushy; the distinction between Aerating and Turning, and the distinct qualities of Hot vs. Cold piles.
Some important compost tips:
- Aerate that pile like you are “tossing a salad,” not stirring pancake batter!
- Chop your ingredients before adding them to your pile. Do not “dump and run.”
- Know your compost’s mood. Too much sun? Too much water? Bad bugs? Stinky? All fixable!
- Compost Happens! The time it takes depends on the ingredients, the care, and attention it gets, like most things in nature.
Sustainable Solano connected Lori Caldwell, consultant, landscaper, and educator, with the Vaca Valley Garden Club. In turn, Lori’s expertise in All Things Compost got people excited about a positive use of leaves, fruit peelings, straw, eggshells, tea leaves and branches. It was a good day for the Garden Club and a good day for Mother Earth!
