Razz is a vigorous Northern highbush blueberry that thrives in hardiness zones 4 through 9, reaching 5 to 6 feet tall at maturity. This midseason variety produces sweet, medium-sized berries with a distinctive light blue color that ripens quickly once it turns from green, offering intense flavor when picked at peak ripeness. Hardy enough to withstand frost and demanding enough to reward consistent care, Razz excels in maritime climates where its love of moisture and acidic soil find ideal conditions.

This Northern highbush grows with impressive vigor, filling out to a full 5 to 6 feet and delivering abundant crops of light blue berries in the middle of the season. The fruit's flavor intensifies as you wait for full ripeness, rewarding patient pickers with a sweetness that justifies the plant's energetic growth habit. Its quick color transition from green to blue makes harvest timing visual and straightforward, and its frost-hardy nature means gardeners in colder climates can depend on reliable production year after year.
Razz berries are best enjoyed fresh off the plant, where their sweet, intense flavor shines brightest when fully ripe. The medium-sized fruit works well for fresh eating, topping yogurt or cereal, and baking into muffins, pies, and jams. The vigorous plant's substantial yields make it practical for preserving and storing.
No timeline data available yet for this variety.
Transplant container-grown plants in early spring or fall, before or just as active growth begins. Harden off by gradually exposing plants to outdoor conditions over 7 to 10 days. Dig a hole as deep as the root ball and twice as wide, amending the surrounding soil with peat moss or sulfur to achieve the required 4.5 to 5.5 pH. Space plants 4 to 6 feet apart to accommodate mature size and allow good air flow. Water thoroughly after planting and mulch heavily.
Watch for the berries to transition fully from green to light blue, a process that happens relatively quickly on this midseason variety. Once the color shift is complete, pick immediately for maximum intensity of flavor; berries picked before full color will lack the full sweetness. Gently twist or cup each berry in your hand and let it roll into your palm when ripe, as fully ripe fruit detaches easily and indicates peak sugar content.
Prune in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing canes, and thin out older wood to encourage younger, more productive growth. On established plants 5 to 6 years old, selectively remove the oldest canes to maintain vigor and fruit quality.
