Crop guides

Spacing, timing for your zone, companions and rotation family for every crop in the planner, grouped by plant family.

Nightshades

Heavy feeders that share early blight, late blight and soil-borne wilts.

Hungry for nitrogen; clubroot spores persist in soil for years.

Host nitrogen-fixing Rhizobium bacteria in root nodules.

Sprawling, thirsty and prone to powdery mildew and cucumber beetles.

Light feeders; fresh manure makes carrots fork.

Shallow-rooted; onion white rot survives in soil for many years.

Quick crops that fill gaps between slower ones.

Wind-pollinated; plant in blocks, not single rows.

Small footprint; many attract pollinators and predatory insects.

Draw pollinators and hoverflies; nasturtiums act as aphid decoys.

Stay put for years; keep them out of the rotation.
