Vertical Garden Calculator

How It Works

Vertical gardening turns unused wall space into productive growing area -- perfect for balconies, patios, small yards, and indoor spaces. The four main approaches each have trade-offs: pocket planters are cheap and lightweight but dry out fast; trellis systems are great for tomatoes and cucumbers but need a strong wall; tower planters hold the most plants per square foot but cost more; gutter gardens are the cheapest DIY option and perfect for herbs and lettuce. The biggest challenge with vertical gardens is watering -- gravity pulls water down, so top planters dry out first. Drip irrigation or self-watering systems solve this. Always check that your wall or fence can support the weight of wet soil (8 lbs per gallon).
