Blueberries
Vaccinium corymbosum
Hardy to Zone 4
These highbush blueberries will grow upwards of 4 feet in height as mature plants and will yield large berries in late summer. Choose a well drained, loamy or sandy soil with a pH of 4.5-5.2. You can reduce your soil pH by mixing in sphagnum peat moss or by mixing in compost made from pine needles, oak leaves and/or bark. Work plenty of nutrient-rich compost into the top few inches of soil. Space plants 4 feet apart, alternating cultivars for effective cross-pollination. Rows should be 7 feet apart. Water with liquid fertilizers such as manure, tea or fish fertilizer. Water frequently and mulch heavily around plants. Growth is slow and production will peak at 6-8 years of age. Yearly pruning of mature plants will encourage larger fruit and heavier production.
