About Blueberries: In addition to the tasty fruit, hardy blueberries make excellent landscape plants. They have glossy-green leaves and attractive flowers and fruit. And in the fall, the foliage turns brilliant orange to red colors. Blueberries require an acid soil with a pH of 4.5 to 5.5 that is well-drained but consistently moist. Full sun for best fruit production. Birds love blueberries so be sure to plant enough to share!

How to Grow

Blueberries require an acid soil with a pH of 4.5 to 5.5 that is well-drained but consistently moist and high in organic matter. They need full sun for best fruit production. Space 3-feet apart. Prune in late winter to maintain desired shape and size.

To prepare your soil, first have it tested for pH. This can be done through your county extension office or ask your garden center for a soil testing kit. Next, add lots of organic matter to increase soil fertility and drainage. Also add sulphur to reduce the pH if necessary. Sulfur chips added to soil will reduce the pH over time. Iron sulphate will reduce the pH quickly, but is not long lasting. Here's a good soil amending recipe for blueberries: for each plant, dig a hole 2-feet wide and about 16-inches deep. Save the top 6 inches of soil and mix in 1 or 2 bushels of compost or well-rotted sawdust and 1 cup wettable sulfur. Mix well and backfill the hole with this after setting your blueberry plant.

Blueberries are produced on one-year old wood. But during the first five years after planting, prune your plants only to remove dead or damaged growth. After five years, prune in the spring before the leaves start to grow by cutting out any weak, old stems at ground level. Keep four to six of the vigorous older stems and one to two strong new shoots per mature bush. The new shoots will eventually replace the older stems.

Fertilize your plants once a year in the spring before the plants bloom with a fertilizer formulated for acid-loving plants, such as azaleas. Also, protect your plants from rabbit damage in the winter by enclosing them in chicken wire.

What's a "bareroot" plant?

Photo of bareroot plant"Bareroot" is a term that describes how a plant is shipped to you. A bareroot plant is not in a pot, and is usually dormant (not actively growing). See the photo to the right that shows what a bareroot rose looks like. The bareroot plants that we ship to you were harvested in the fall and placed in cold storage over the winter to keep them dormant. In the spring, we ship the bareroot plants to our customers, from early April through mid May.

Bareroot plants are easy to grow. We include planting instructions with your order. When you receive your plant, take it out of the packing material and place it in a bucket of water so that the roots are completely covered. Let the roots soak for 4 to 24 hours, then plant it in your garden. Full planting instructions with photos are available on our planting shrubs page.
