When to Plant Raspberry in Idaho

Growing Raspberry in Idaho: Complete Guide

Raspberry (Rubus idaeus) is a crop that grows best when sown directly in the garden. Depending on your zone, the right time to direct sow in Idaho falls between March 8, 2027 (Zone 7b) and April 17, 2027 (Zone 4a), once soil temperatures are consistently warm enough for germination.

Because Idaho stretches across 8 USDA hardiness zones (4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b), planting windows can shift by as much as six to eight weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 365 days to maturity, Raspberry fits comfortably within Idaho's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Raspberry requires full sun and regular moisture. Mountain-state gardens contend with short seasons and intense UV at elevation — cold nights can persist well into June at higher altitudes.
