How many tomato plants fit in a raised bed?
At standard square-foot gardening spacing of 60cm, a typical 240cm x 120cm raised bed fits 8 tomato plants (4 columns x 2 rows). Smaller cherry tomato varieties may be spaced closer at 45cm, fitting 10-12 plants in the same bed. The calculator adjusts for the exact bed dimensions and spacing you specify.
What is companion planting?
Companion planting is the practice of growing certain plants near each other for mutual benefit. Classic examples include the Three Sisters (corn, beans, squash) where each supports the others. Some plants inhibit neighbours: fennel suppresses most vegetables; tomatoes and potatoes share diseases and should be separated; onions and garlic inhibit beans and peas. The calculator flags incompatible combinations.
What is square foot gardening spacing?
Square foot gardening uses a grid where each cell is one square foot (30x30cm). Different vegetables get different numbers of cells per plant: large plants like tomatoes need one full cell (60cm); medium plants like lettuce get 4 per cell (25cm); small plants like radishes get 16 per cell (8cm). This system maximises yield from limited bed space.
