Blueberries

When to Plant Blueberry Bushes

• Blueberries can be planted in spring or also in late fall in all but coldest regions. In Zones 5 and below, it’s best to wait until early to mid-spring to plant. 
• If available, 1- to 3-year-old plants are a good choice. These can be bought in containers or bare-root. In either case, be sure to buy from a reputable nursery or website. 

Choosing and Preparing a Planting Site

• Select a sunny, sheltered spot. While blueberries are tolerant of shade, better crops are obtained in the sun. At the same time, they should not be exposed to harsh, drying winds.
• Don’t plant blueberries too close to trees, as the trees will not only block out sunlight, but will also suck up any moisture in the soil.
• If planting multiple bushes, it’s best to plant them in a patch, rather than scattered throughout your garden. This will bolster berry production and quality.
• The blueberry is a shallow-rooted plant. Therefore, it requires a soil that holds moisture, but also drains well and doesn’t stay wet. Don’t plant blueberries in sites that have heavy, clayey soils that stay wet.
• Blueberries thrive in soil that is acidic. The soil pH should ideally be between 4.0 and 5.0; soil that isn’t acidic enough will stunt growth. Soil can be acidified by mixing a small amount of granulated sulfur into the soil several months before planting. Peat moss, as well as pine bark or needles, are also good additions that will help acidify your soil.
• Mix organic matter into the soil before you set your blueberry bushes. (See more about soil amendments and preparing soil for planting.)

How to Plant Blueberry Bushes

• Tip: Be careful not to plant them too deeply. The rootball should be just below the surface (one-quarter to one-half inch).
• Dig holes about 20 inches deep and 18 inches wide (or about twice as wide and twice as deep as the roots of the plant).
• Space bushes 4–5 feet apart in a row, with at least 8 feet between rows. Prepare a planting mixture of 2 parts loam and one part oak leaf mold, peat moss, aged sawdust, or compost, and place a layer of this mixture in the bottom of the hole.
• Set the bush in the hole with the rootball just below the surface and its roots spread out. Pack the hole tightly with soil.
• Apply fertilizer one month after planting, not at the time of planting. Apply ½ ounce of a 10-10-10 fertilizer in a band around the plant 6 to 12 inches from the crown.

Can You Grow Blueberries in a Container?

Yes! In fact, blueberries grown in containers are easier to protect from birds and other critters, more disease resistant, easy to harvest, and easy to move if needed. Plus, if you live in an area without acidic soil, growing blueberries in containers allows you to tailor the soil pH specifically for them.

Here’s how to do it:

• Use a large container with drainage holes.
• Use a potting mix designed for acid-loving plants such as azaleas or rhododendrons, or mix sandy soil with peat moss and compost.
• Plant the bush in the container and water well.
• Add mulch on top of the soil to keep in moisture.
• Place the pot in a sunny spot.
• Keep soil moist.
• In northern regions, overwinter the blueberry container in a protected area or cover the container with straw or wrap it in burlap.

Varieties for Containers

• ‘Top Hat’: Bred by the University of Michigan for small spaces and containers.
• ‘Pink Lemonade’: Pink blueberries contain genetics from rabbiteye blueberries (a standard in the hot South). These pink berries can be planted in nearly every climate.
• ‘Pink Champagne’: Another pink variety full of antioxidants and sweeter than blue blueberries.
