Spinach + Radish

Spinach and radish share the same cool-season window, making them a practical pairing for spring and fall beds. Both crops prefer soil temperatures between 45°F and 65°F and will bolt when sustained heat arrives, so the partnership has a built-in expiration date tied to the season rather than anything about the plants themselves.

Radish is the faster partner: most varieties mature in 22 to 30 days. Sowing radish seed alongside or just ahead of spinach marks the row clearly during the weeks when spinach germinates slowly, and pulling the radishes at harvest opens small pockets of space and loosens the soil around maturing spinach roots.

Spacing works because neither crop is large. Interplant radish seed every 2 to 3 inches within spinach rows, or alternate short rows. The pairing is less useful in summer plantings, where both crops will struggle regardless of what grows beside them.
