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