How to Manage Pests

Pests in Gardens and Landscapes

Time to plant

Spinach matures quickly and is a hardy cool-season vegetable crop. The ideal temperature for growth is 40° to 75° F and is most rapid at 60° to 65° F. Spinach can tolerate temperatures of 15° to 20° F without injury. However, freezing temperatures can harm small seedlings and plants at maturity. Intermediate-size plants can handle subfreezing temperatures for weeks.
