Frequently Asked Questions

What is square foot gardening?

Square foot gardening divides raised beds into 1-square-foot sections, each planted with a set number of plants based on spacing needs. It produces significantly more food per square foot than traditional row gardening.

How far apart should I plant tomatoes?

Indeterminate varieties need 24-36 inches between plants. Determinate varieties can be 18-24 inches apart. One tomato per square foot works for determinate varieties on a trellis.

What is triangular offset spacing?

Triangular offset spacing offsets every other row by half the plant spacing instead of aligning rows in a square grid. This fits approximately 15% more plants in the same area and is ideal for dense crops like carrots, onions, and radishes.
