Highbush Blueberry

What you'll need:

Acidic soil mix (blueberries love acidic soil, so look for something labeled "ericaceous compost" or "acidic potting mix")

A large pot (at least 18 inches wide) or a garden space with well-draining soil

Mulch (pine bark or pine needles work well)

Fertilizer designed for acid-loving plants (like those used for azaleas or rhododendrons)

• Highbush blueberry plants (you can buy these as small potted plants from garden centers)

When to start:

Spring is the best time to plant your highbush blueberry. The weather is mild, and it gives the plant time to settle in before winter. If you're buying a young plant, try to get it in early spring when it's still dormant.

Finding a good spot:

Highbush blueberries love sunshine but also appreciate a bit of afternoon shade in hotter climates. They need at least 6 hours of sunlight daily. If you're planting in pots, a sunny balcony or patio works great. For garden planting, choose a spot with good drainage—blueberries don't like soggy feet!

Soil Check: Blueberries prefer acidic soil with a pH between 4.5 and 5.5. You can test your soil with a simple pH kit from a garden store. If your soil isn't acidic enough, it's better to grow them in pots with ericaceous compost rather than trying to change your garden soil.

If planting in a pot:

1. Fill the bottom of your large pot with some gravel or broken pottery to help with drainage.
2. Add your acidic potting mix until the pot is about halfway full.
3. Gently remove the blueberry plant from its nursery pot and place it into the new pot.
4. Fill around the plant with more acidic soil, leaving about an inch of space at the top of the pot.
5. Water thoroughly right after planting, making sure the water drains out of the bottom.

If planting in the ground:

1. Dig a hole that’s about twice as wide and just as deep as the root ball of your blueberry plant.
2. Mix some acidic compost into the soil you’ve dug out.
3. Place the plant in the hole and fill in around it with the amended soil.
4. Pat down gently to remove air pockets and water deeply.

Spacing Tip: If you’re planting more than one blueberry bush, space them about 4-5 feet apart. This gives them room to grow while allowing for good air circulation.

Mulching: After planting, spread a layer of mulch (pine bark or pine needles) around the base of the plant. This keeps the roots cool, retains moisture, and helps maintain the soil’s acidity.

Watering:

• Blueberries like consistent moisture, but they hate sitting in waterlogged soil. Aim to keep the soil moist but not soggy.
• Rainwater is best for watering because tap water can be too alkaline. If you can, collect rainwater in a bucket or barrel.
• Water every 2-3 days during dry spells, especially in the first year while the plant is getting established.

Feeding Time:

• Use a fertilizer made for acid-loving plants, following the instructions on the package.
• Feed your blueberry plant in early spring and again in late spring or early summer.
• Avoid over-fertilizing—blueberries are light feeders, and too much fertilizer can harm them.

Pruning:

• Start pruning your blueberry bush in its third year. Remove any dead or crossing branches to open up the center of the plant for better air circulation.
• After the plant has been growing for 5-6 years, remove some of the oldest, thickest stems each year to encourage new growth.

Sunlight & Temperature:

• Make sure your blueberry plant gets plenty of sunlight, but if you live in a hot climate, give it some afternoon shade.
• Blueberries are hardy plants, but young plants may need protection from harsh winter winds. You can wrap them in burlap or use frost cloth if needed.

Bird Protection:

• Birds love blueberries as much as we do! Once your plant starts producing fruit, consider covering it with bird netting to protect your harvest.

When to pick your blueberries:

• Blueberries will be ready to harvest in mid to late summer, depending on your climate.
• The berries should be fully blue and come off easily when gently tugged.
• Don’t rush the harvest—berries sweeten up after they turn blue, so wait a few days after they color up before picking.

How to pick:

• Use your fingers to gently twist the berry off the stem.
• Be careful not to damage the plant as you pick, since blueberries will continue to produce fruit for many years.

Storage Tips:

• Fresh blueberries can be stored in the fridge for up to a week.
• If you have a big harvest, you can freeze them by spreading them out on a baking sheet, freezing them individually, and then transferring them to a freezer bag.
• Frozen blueberries are perfect for smoothies, pies, or muffins!

Q: Why are my blueberry leaves turning yellow?

A: Yellow leaves could mean the soil isn’t acidic enough. Test your soil and amend it with acidic compost or fertilizers if needed. It could also be a sign of overwatering.

Q: Do I need more than one blueberry plant to get fruit?

A: While some blueberry varieties are self-pollinating, you'll get a better harvest if you plant two different varieties that bloom at the same time. Cross-pollination helps increase fruit size and yield.

Q: How long does it take for blueberries to produce fruit?

A: You’ll likely see a small amount of fruit in the second or third year, but it can take 5-6 years for the plant to reach full production. Be patient—your blueberry bush will reward you with more fruit as it matures!

Q: Can I grow blueberries in a pot?

A: Yes! In fact, many people grow blueberries in pots, especially if their garden soil isn’t acidic enough. Just make sure the pot is large enough and filled with acidic soil.

Q: What pests should I watch out for?

A: Birds are the biggest threat to your blueberries. Other common pests include aphids and spider mites. You can control these with insecticidal soap or by introducing beneficial insects like ladybugs.
