Polaris Blueberry

Plant in spring or fall in acidic, well-drained soil, spacing 4–5 feet apart. Polaris is a half-high blueberry variety developed specifically for extremely cold climates, producing large, flavorful berries on a compact, manageable plant. Acidic soil with pH 4.5–5.5 is essential. Test soil and amend if needed. Mulch with wood chips to maintain acidity and moisture. Plant two varieties for best pollination.

Prune in late winter by removing old, unproductive canes and weak growth. Fertilize with an acid fertilizer in spring. Water consistently during fruit development. Polaris is one of the most cold-hardy blueberry varieties available — an excellent choice for northern gardens where many blueberries would not survive. The compact, half-high habit is also more manageable than full-sized highbush varieties. Large, flavorful berries.
