LONG-LIVED AND DEPENDABLE, blueberries are among the easiest fruits to grow organically. Different species are native to various regions of North America, but you can grow some type of blueberry bush almost anywhere. The limiting factor is soil acidity: except for saskatoons, blueberries require acidic soil with a pH below 5.0. Blueberries can also be grown in containers filled with an acidic bark-based planting mix.

healthy berries, as well as stunning red and orange fall foliage.

TYPES OF BLUEBERRIES TO TRY

Lowbush blueberries are native to colder parts of North America. The compact bushes can be grown as an edible hedge or groundcover, even in partial shade, and they bear delicious berries that hold on the plants for a long time.

The hardiest varieties can survive to -60°F. Related to roses, the almond-scented fruits easily pass for true blueberries. Saskatoons prefer a near- neutral soil pH between 6.0 and 7.0.

WHEN TO PLANT BLUEBERRIES

Late winter or early spring, during the 6 weeks prior to your last spring frost, is the best time for planting blueberries. Young container-grown plants may be set out later but need time to grow roots before hot weather. Blueberries are only marginally self-fertile, so you’ll need to grow at least three plants of compatible varieties.

HOW TO PLANT BLUEBERRIES

Choose a sunny, well-drained site that has an acidic pH for growing blueberry bushes. Young blueberry plants need an abundance of organic matter in the soil’s shallowest layers. Most soils should be amended with 4 inches of acidic organic matter such as rotted sawdust or leaf compost. Preparing the site in fall will help the organic matter settle into the soil, which will enhance transplant survival in spring. If your soil’s natural pH ranges between 5.5 and 6.0, you can further acidify it by top-dressing with soil sulfur twice a year. In areas with soil pH levels above 6.0, grow blueberries in large containers filled with a wood chip– or
