Care Guide | Blueberries
While you know blueberries are always delicious and nutritious, you may not know that they are not always blue; take the Pink Lemonade, for example, which boasts pretty pink berries instead of the typical blue. Blueberries are such a fun crop to grow because you can eat them straight off the bush. Don't have a lot of growing space? No problem--Grow indoors or on your patio with a dwarf variety like Top Hat. In fact, growing blueberries in a pot is very beneficial for them so you can better control the soil and moisture levels they need to thrive.
Characteristics
Blueberry plants are slow to moderate-growing, long-lived perennial shrubs. They prefer full sun and acidic, well-drained soil. Blueberries grow as woody shrubs with multiple stems and small, oval leaves that turn vibrant shades of red in fall. Most varieties reach 3–6 feet tall and begin producing fruit within 1–3 years. Dwarf varieties grow to a compact 1–2 feet tall. Most blueberry varieties benefit from cross-pollination. While some are self-fertile, planting multiple varieties can significantly increase fruit yield and berry size. They also benefit from proper soil conditions and consistent care for best results.
There are three main types of blueberries categorized by the areas in which they thrive:
Northern Highbush varieties require significant winter chill and are best suited for cooler regions, producing classic large berries with excellent flavor.
Southern Highbush types are bred for low-chill areas, making them ideal for warmer climates while still offering high-quality fruit and earlier harvests.
Rabbiteye are the most heat- and drought-tolerant of the three, thriving in the Southeast; they tend to grow taller, produce abundant smaller berries, and typically require cross-pollination with another Rabbiteye variety for best yields.
Popular Varieties

Scientific Name
Blueberries belong to the Ericaceae family and are classified under the Vaccinium genus. There are several cultivated species, including highbush (Vaccinium corymbosum) and rabbiteye (Vaccinium virgatum).
Classification
Blueberries are deciduous perennial shrubs that produce fruit annually once established. They have woody stems and produce small, bell-shaped flowers that develop into berries. Proper pollination plays an important role in fruit production.
USDA Hardiness Zones
Blueberries grow best in USDA Zones 3–10, depending on the variety. Northern highbush types prefer cooler climates, while southern highbush and rabbiteye varieties tolerate warmer regions. Some varieties perform well even in Central Florida with proper care and soil preparation.
Plants have a culture they prefer, just as people from various countries and households have their own customs and traditions. The U.S. Department of Agriculture created the USDA hardiness zone map to help gardeners identify the areas in which plants tend to grow well based on past average temperatures/climates. On the USDA's site, you can enter your zip code to identify your hardiness zone. No fear if you live outside the hardiness zone—you can still grow successfully indoors with proper adjustments.
Height Potential
Blueberry plants typically reach 2–6 feet tall, depending on the variety. Dwarf types stay compact and are ideal for containers, while standard varieties grow into fuller shrubs.
Planting
Blueberries prefer to be planted in acidic soil (pH 4.5–5.5) with good drainage. Space plants 3–5 feet apart. Planting multiple varieties improves pollination and fruit production.
Light
Blueberries thrive in full sun and require at least 6–8 hours of direct sunlight daily. Less light results in reduced fruiting and slower growth.
Soil/Watering
Blueberries require acidic, well-drained soil rich in organic matter. Keep the soil consistently moist but not waterlogged. Mulching helps retain moisture and regulate soil temperature.
Fertilizer
Use a fertilizer formulated for acid-loving plants. Apply lightly in early spring and again after fruiting. Avoid over-fertilizing, which can damage roots.
Pruning
Prune annually during dormancy to remove dead wood and encourage new growth. This improves airflow and fruit production.
Cold Weather Care
Most blueberry varieties are cold-hardy, but protection may be needed during extreme freezes. Container plants can be moved to sheltered areas if necessary. Learn more in our Overwintering Guide.
Fruiting and Harvesting
Blueberries typically begin producing fruit within 1–3 years. Harvest when berries are fully blue and easily detach from the plant. Regular picking encourages continued production.
Common Pests
Common pests include aphids, spider mites, and birds. Netting can help protect ripening fruit. Neem oil may be used for insect control.
Toxic to Pets?
Blueberry plants are not toxic to pets and are generally safe if consumed.
After Arrival Care
Please give your plant a little TLC after its journey through the mail 📬. Here are a few steps we recommend:
- Unwrap immediately to provide fresh air to the plant and soil.
- Wait a few days before exposing to full sunlight so your plant can adjust after being in a dark box for several days.
- Always protect from heat and cold because temperature extremes can be stressful or deadly for plants.
- Water. Your baby plant may be parched and even a little wilted but thorough hydration will help it recover.
- Grow out in a larger pot to increase your chances of success—i.e., a quarter gallon—Then transplant to the ground or the next pot size up once the roots fill to the bottom. This will help the plant get sufficient water and nutrients directly to the roots.
Learn more in our After Arrival Care Guide.
Repotting
We highly recommend growing your baby plant out in a larger pot 🪴 to increase your chances of success 🏆. Repotting helps focus the water and nutrients directly towards the roots. If the pot is too large or if your baby is planted in the ground, the water and nutrients have more room to spread to the wrong places where they aren’t needed. This can be extra detrimental to a baby plant that needs all the support it can get as it’s growing up. You don’t have to repot immediately, but the sooner you do, the more room it has to grow.
Here are some general repotting tips:
- Start with a pot that's 1–2 inches larger in diameter than the starter-sized pot it came in. A pint or quart would be great.
- Transplant to the next pot size up once the roots fill to the bottom.
