This is so cool! 😎
Fifty salad plants in a two-foot circle. No raised bed, no dedicated garden space — just a barrel, a PVC pipe, and a bag of potting mix. 🌿
How to build a salad barrel tower:
Start with a large plastic barrel or trash can — 30 to 55 gallons works well. Drill 2-inch holes in a staggered pattern around the sides, spacing them 6 to 8 inches apart in every direction. These become the planting pockets.
Cut a 4-inch diameter PVC pipe or roll hardware cloth into a cylinder about 3 inches across. This goes in the center of the barrel as a watering core. Cap the bottom end. Once the barrel is filled, water goes into this central tube and wicks outward to roots throughout the entire barrel — without it, the interior stays dry while the outside stays wet.
Fill with a mix of organic potting soil and compost as you go, planting a seedling into each hole as you fill up to that level. Work from the bottom up. Gently guide the roots inward, pack soil around the collar of each plant, and continue filling. Plant the top of the barrel with the largest heads — lettuce varieties, kale, or chard.
What grows well in the holes: loose-leaf lettuce in any variety, spinach, arugula, herbs like parsley and cilantro, strawberries along the lower holes where runners can hang freely, and green onions in the uppermost holes.
Harvest method: walk around the barrel with scissors and clip outer leaves from each plant as needed. Cut-and-come-again varieties like loose-leaf lettuce will regrow 5 to 8 times from the same plant. 🌱
A single barrel in full sun produces more salad greens than most 4×8 raised beds. Two feet of floor space. No weeding. No bending. 🥬
