The Garden Tower 2 makes a bold claim: grow up to 50 plants in just 4 square feet of space, using kitchen scraps to feed the plants through an integrated composting system. For apartment dwellers, small-yard homeowners, and anyone who wants to grow more food with less space, the concept is compelling. We tested it through a complete growing season to see if it holds up.
The Garden Tower ships pre-assembled. You fill it with potting mix, insert plant starts or seeds into the pockets, load kitchen scraps into the central compost tube, and start watering. The tower rotates 360° to ensure every plant gets adequate sun exposure.
We planted herbs (basil, parsley, mint, chives), salad greens (lettuce, spinach, arugula), strawberries, and cherry tomatoes. The herbs and greens performed excellently. The tomatoes grew but required staking and more attention than the tower's design anticipates.
The central compost tube is the Garden Tower's most innovative feature. Kitchen scraps go in the top, decompose with the help of worms (we added red wigglers), and feed the plants through the tower walls. In practice, it worked well — plant growth was noticeably more vigorous than our control soil pots.
