Steps
- 1Pick a fence or wall with morning sun and afternoon shade in hot climates.
- 2Locate fence posts or studs; mark bracket locations on solid framing, not thin pickets.
- 3Install brackets with a slight downward tilt toward one end for drainage.
- 4Space tiers roughly 12 inches apart so the top gutter doesn't shade the bottom ones.
- 5Drill small drainage holes every 6 inches along the gutter bottom.
- 6Snap gutters into brackets and seal end caps.
- 7Fill with light potting mix only — never garden dirt.
- 8Plant shallow-rooted herbs, lettuce, or strawberries, leaving space for airflow.
- 9Water gently until drainage appears; check moisture daily in hot weather.
Tools needed
- ·Cordless drill / driver
- ·Tape measure and level
- ·Hacksaw if cutting gutters
Common mistakes to avoid
- ·Screwing brackets into thin fence pickets instead of posts — three watered tiers can weigh 120–210 lb
- ·No drainage holes — roots rot fast
- ·Using heavy garden soil — it compacts and cracks gutters
- ·Mounting perfectly level — water sits in one end
- ·Planting deep-rooted crops like tomatoes — gutters are too shallow
- ·Reusing an old metal gutter with leftover paint or sealant
Maintenance tips
Water often — shallow gutters dry out fast. Trim herbs to keep them compact. Empty and refresh soil each spring.
