Key Points
Planting blueberry bushes at the right time ensures a healthy harvest and helps your plants thrive for years.
The best time to plant blueberries is early spring or fall, when the plants are dormant, and soil is cool.
Avoid planting too early or too late, as extreme cold or heat can damage roots and stress the plants.
The journey to cultivating blueberry bushes begins long before the first fruits appear. Just like other crops, blueberries have an ideal planting window that can make or break their health and harvest. To help you get it right, we spoke with gardening experts about the best time to plant blueberries and practical tips to ensure a smooth transition into the soil.

When to Plant
The best time to plant blueberry bushes is in early spring or fall when the plants are dormant, according to Renata Scarano, owner of Blue-Zee Farm. This timing allows the plants to establish their roots in cool, moist conditions and will help minimize transplant shock.
In spring, it’s best to start planting as soon as the ground is workable, which typically falls between early and mid-spring. For those considering fall planting, aim to dig in about 60 to 90 days before the first hard frost arrives.
What Happens When You Plant Too Early?
“When planting blueberries too early, you risk drying out the rhizomes, which can lead to plant death,” says Scarano.
Planting too early—before the soil has warmed or during periods of frequent hard freezes—can lead to several problems. Cold soil below 50 degrees Fahrenheit can cause root damage, stunted growth, and transplant shock.
If a plant blooms early due to a warm spell followed by a hard frost, the flowers may die, resulting in a lost harvest. In extreme cases, frozen soil combined with strong winds can dehydrate plants and kill them entirely.
What Happens When You Plant Too Late?
While summer is an ideal time to plant heat-loving crops like tomatoes, blueberries need cool soil and time to adjust before the heat arrives. Planting blueberries too late, especially in summer, can cause the plants immense stress. The plant will instead focus all its energy on surviving the heat, rather than on developing a strong root system.
Tips
To help a blueberry bush that was planted too late in the season, keep it heavily mulched, with 4 to 6 inches of mulch, and water it daily.
Tips for Planting
Now that you know the ideal times, these tips will help ensure a successful transplanting.
Select the Right Variety
Selecting the right variety for your growing region is essential.
“Highbush varieties are a good choice for northern growers, while southern highbush and rabbiteye varieties are better suited to warmer climates,” says Lisa Rayburn, area extension agent at the North Carolina Cooperative Extension Service.
Contact your local nursery regarding recommended varieties for your growing zone.
Location Matters
Blueberries thrive in full sun, requiring 6 to 8 hours of sunlight each day. They prefer moist, well-drained, and acidic soil. “If your location doesn’t have good drainage, consider planting blueberries in a raised bed,” says Rayburn.
Conduct a Soil Test
“Conduct a soil sample before planting,” says Rayburn. “Soil sampling services are available through your local extension office or land grant university.” If necessary, elemental sulfur can be used to lower the soil pH.
Add Mulch
Rayburn recommends adding 3 to 4 inches of organic matter, such as fine pine bark mulch, and working it into the soil before planting. “Use additional organic mulch to protect the surface of the soil and keep it weed-free,” she adds.
How to Care for Blueberries
Proper aftercare is important, as blueberries require annual pruning, fertilizing, and intentional watering.
Watering
In the first year, it’s important to keep the soil consistently moist. It should feel wet, but not saturated. Aim to provide 1 to 2 inches of water per week, and increase this amount during hot, dry periods.
“Irrigate blueberry bushes during dry spells,” says Rayburn. This is vital for young plants as they establish their roots.
Pruning
“Blueberry plants should be pruned each winter to remove canes older than three years,” says Rayburn.
At this time, about 40 percent of the flower buds should be removed to ensure a crop of large, quality berries that ripen evenly. However, in the first two to three years, only remove dead, diseased, weak, or thin growth.
Fertilization
Fertilize blueberries twice a year: once in early spring and again in late spring. Choose a fertilizer specifically designed for acid-loving plants, and follow the instructions on the packaging.
