When to Plant Raspberry in Montana

Growing Raspberry in Montana: Complete Guide

Raspberry (Rubus idaeus) is a crop that grows best when sown directly in the garden. In Montana, the right time to direct sow is around Sunday, April 12, 2026, once soil temperatures are consistently warm enough for germination.

Because Montana stretches across 7 USDA hardiness zones (3b, 4a, 4b, 5a, 5b, 6a, 6b), 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 Montana'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. Most of Montana receives adequate sunlight during the growing season, though gardeners in humid eastern regions should watch for fungal issues and ensure good air circulation.
