Blueberries are the ultimate fruit bearing shrub for people who want to make the most use of planting shrubs for beauty, but will also produce a tasty and healthy treat.
Easy to grow and integrate into an established garden, blueberries are attractive shrubs in their own right, that people really don’t think of using when planning their landscape. Easy to fit into a small landscape, blueberries exhibit wonderful fall color as well as being attractive shrubs the rest of the year, especially in the fall when they turn a spectacular red color as the days turn cooler. An unexpected source of fall color for most people, and a great provider of breakfast blueberries-what’s not to love?
A half dozen blueberry bushes are planted in the high shade of large trees on my property, and I amended the soil with plenty of moistened peat moss. Planting the shrubs about five feet apart gives them enough growing space. If you plant them in the landscape as a shrub accent in a flower bed, you can group them a little closer for a bigger impact. I find that deer leave the shrubs alone but will browse on the ripe berries, as well as birds. Bird netting set up over a framework of PVC pipe keeps the berries going into your pies instead of feeding the wildlife. But if you plant enough bushes, you will have enough for the wildlife as well as yourself.
Plant as early in the spring as possible is best, though I have been quite successful planting them later in the spring and into the summer. Resistant to most pest and diseases, I have been growing my blueberries for over 25 years with bushes that keep on producing plump juicy berries. Offering scarlet fall foliage and pale-yellow bell-shaped spring flowers, my honey bees flock to gather nectar and pollen from them, and is one of the reasons I grow them.
Steps for Planting
- Select a spot in full sun or partial shade.
- Test your soil pH by digging a small sample and take to a nearby nursery to have tested. The soil pH should be optimally between 4 and 5. To acidify your soil or to lower the pH, mix a small amount of granulated sulfur into the soil several months before planting. Also mixing organic materials such as peat moss, pine bark, leaf mold, aged sawdust, and pine needles into the soil will help acidify your soil and lower the pH before planting.
- Buy a blueberry bush that is at least one year old or older to get a head start on bearing.
- Dig hole about twice as wide and deep as the root ball and add some loamy soil and compost to the hole.
- Place the shrub at the same level as the pot into the hole and back fill with soil and pack firmly.
- Water thoroughly.
- About one month after planting, fertilize with a general 10-10-10 granular fertilizer or a liquid fertilizer like fish emulsion.
- Blueberries are self-pollinating but will grow larger fruit through cross-pollination with a companion bush.
Blueberries are one of the easiest plants to harvest with very little effort. The berries are held upright on small shrubs so are easy to reach with little bending over, unlike strawberries and raspberries. It is important to wait until the berry ripens completely with a rich blue color all around as the berries will not ripen any further after you pick them. The berry will reach its full flavor and aroma a few days after the blue color appears.
Hanging an old cut off gallon milk jug around my neck, which frees both hands to pick, is the most efficient way.
The berries ripen over several weeks, so my harvest is spread out and I enjoy them on cereal and pancakes for about a month in late June and early July. My excess berries are washed, spread out to dry, and packed into freezer baggies for future use.
People are quite successful growing blueberries in large containers. Use the same soil mix as above and use a large enough container that the plant can grow, but that you can also move around if needed. Overwinter the container by wrapping burlap or straw around the plant and placing in a protected location from winds. Successful blueberry growing though, is having the right soil mix with plenty of peat moss added, in a container or in the ground.
When your bushes get older, at least 4-5 years old, it is time to start pruning to keep them producing each year. The berries are produced on newer canes, so the best strategy is to remove older and diseased canes as well as crossing branches with a sharp pruner. Then trim the rest of the longer arching branches back by about 1/4 to 1/3. The goal when pruning is to achieve a narrow base and open top that allows sunlight to penetrate and good air circulation. The best time to do this is late winter while the bushes are dormant, and it is easy to see the structure. To ensure plentiful harvests, you should continue to do this every year.
