Growing Your Own Blueberries

Growing your own blueberries offers more than just delicious, nutrient-rich fruit. It’s a rewarding experience that connects you to nature, beautifies your garden, and gives you pride every time you harvest berries you nurtured from young plants.


Getting Started with Blueberries

Before planting, it’s important to plan carefully to give your blueberry bushes the best chance to thrive. Successful blueberry growing depends on good site selection:

  • Sunlight: Blueberries need full sun—at least 6 to 8 hours daily—to produce abundant fruit.

  • Soil: Blueberries prefer acidic, well-drained, sandy or loamy soils with a pH between 4.5 and 5.5. Testing your soil’s pH and nutrient levels helps you prepare the bed correctly.

  • Space: Give each bush enough room to grow—usually about 4 to 6 feet apart—so they don’t compete for nutrients or crowd each other.

  • Pollination: While many blueberry varieties are self-pollinating, planting multiple varieties nearby can improve yield and fruit size.

You can start with container-grown or bare-root blueberry plants. Both do well if planted properly and given consistent care.


Caring for Your Blueberries

After planting, regular care is key to healthy bushes and a bountiful harvest.

  • Watering: Blueberries have shallow roots and need consistent moisture, especially during flowering and berry development. Aim to keep soil evenly moist but not waterlogged.

  • Mulching: Apply acidic organic mulch like pine needles or shredded bark to conserve moisture, suppress weeds, and maintain soil acidity.

  • Pruning: Prune annually to remove old, weak canes and encourage new growth, which produces the best fruit.

  • Fertilizing: Use fertilizers formulated for acid-loving plants. Timing is important—feed bushes in early spring and again after harvest, but avoid late-season fertilizing to prevent tender new growth before winter.

  • Pest and disease management: Monitor bushes regularly and apply appropriate controls as needed to protect against common blueberry pests like aphids, birds, and diseases such as mummy berry or powdery mildew.

Growing Blueberries: A Rewarding Journey

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

There’s something truly special about growing blueberries—whether it’s harvesting your own sweet, juicy berries, connecting to nature, or simply enjoying the satisfaction of nurturing healthy plants that thrive in your garden.


Where to Begin: Planting with Purpose

Before you plant your blueberry bushes, it’s worth spending some time planning. Choosing the right location can make all the difference in how well your plants grow and how much fruit they’ll produce. Key factors to consider include sunlight exposure, soil acidity and quality, spacing, and pollination needs. While many blueberry varieties are self-pollinating, planting multiple varieties nearby often boosts fruit set and size.

Getting to know your soil is essential. Blueberries prefer acidic, well-drained soils with a pH between 4.5 and 5.5. Different soil types affect root development and water retention, so proper preparation is key. Our 1st Choice Fertilizer guides walk you through soil testing and amendments to create ideal planting conditions. Whether starting with bare-root or container-grown bushes, both are beginner-friendly with the right preparation.


Ongoing Care: Keeping Your Blueberries Healthy

Once your bushes are in the ground, ongoing care ensures they stay productive year after year. Watering is critical—blueberries have shallow roots and need consistent moisture without becoming waterlogged. Mulching with acidic organic materials like pine needles helps retain moisture and maintain soil acidity.

Pruning annually encourages vigorous new growth, which produces the best berries. Fertilizing with acid-loving plant formulas supports healthy growth and fruiting—timing your applications early in the season and after harvest helps avoid late-season growth vulnerable to winter damage.

You’ll also want to watch for common pests and diseases, like aphids, mummy berry, or powdery mildew. Our guides include safe, effective prevention and treatment options to protect your crop while keeping your garden eco-friendly.

Acclimating Blueberry Plants Before Planting

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Before your blueberry plants settle into their new home, one crucial step helps ensure a strong start: acclimation—also called hardening off. This process gently prepares your young bushes for the outdoor environment, especially if they’ve been grown in controlled greenhouse conditions.

At 1st Choice Fertilizer, many of our potted blueberries come from greenhouses, often arriving with tender new growth. While this fresh foliage is a good sign of health, it also means your plants are vulnerable to outdoor stresses like sun, wind, temperature swings, and dryness.


Why Acclimation Matters

New blueberry shoots and leaves are sensitive to environmental stress. Skipping the acclimation step can cause leaf scorch, wilting, or transplant shock. Conditions that may harm young plants include:

  • Temperatures below 50°F or above 85°F

  • Sudden frost or late-season cold snaps

  • Intense, direct sunlight

  • Strong, drying winds

These factors are common in early spring or fall, depending on your region, so easing your plants into outdoor conditions helps build hardiness.


Acclimating Bare-Root Blueberries

Bare-root blueberry plants arrive dormant, without soil around their roots. This dormancy protects them during transplant, but gentle care is still important.

Before planting:

  • Soak roots in water for 1–2 hours (no more than 24 hours) to rehydrate.

  • Plant as soon as possible, ideally in early spring or fall when temperatures are moderate.

  • Avoid planting late in the season to minimize shock risk.


Acclimating Potted Blueberry Plants

If your blueberries arrive in containers with leafy growth, they likely need a gradual transition from greenhouse to garden.

Here’s how to help them adjust:

  • Unpack and place plants in a shaded, sheltered spot outdoors—such as a porch or under a tree canopy.

  • After 1–2 days, gradually increase sun exposure by moving plants to a brighter location.

  • Water thoroughly upon arrival, then allow the top inch of soil to dry between waterings. This encourages root development and drought tolerance.

  • Monitor leaves for browning or curling; if spotted, move plants back to filtered light and protect from wind.

  • Cool breezes are beneficial but avoid leaving plants outside overnight if temperatures drop below 40°F. Bring indoors if necessary.

After 3–5 days, if weather is mild and soil temperatures are above 50°F, your blueberry plants should be ready for planting. Choosing a cloudy or overcast day for transplant helps reduce stress.


A Few Extra Tips

  • Adapt to your climate: Depending on your location and season, plants may need more or less acclimation time.

  • Indoor option: If outdoor conditions are too harsh, keep potted blueberries near a bright window and treat them like houseplants until weather improves.

  • Be patient: Each plant adjusts at its own pace—some will harden off quickly, while others need extra care.

Proper acclimation sets your blueberry plants up for success, helping them grow strong and fruitful in their new garden home. With 1st Choice Fertilizer, you’re supported every step of the way.

Choosing the Right Location to Plant Blueberries

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Success starts before you ever put a shovel in the ground. Choosing the perfect spot for your blueberry plants can save you from future headaches—and give your bushes the best chance to thrive and produce those beautiful, juicy berries for years to come.

Here are five key factors to consider before planting your blueberries:

  • Soil acidity and drainage

  • Sunlight requirements

  • Surroundings and protection

  • Spacing between plants

  • Room for future growth


1. Soil Acidity & Drainage: The Foundation of Healthy Blueberries

Blueberries are a bit pickier than many other fruit plants—they thrive in acidic soils with a pH between 4.5 and 5.5. Before planting, test your soil’s pH and amend if needed with sulfur or peat moss to achieve the ideal acidity.

Good drainage is also crucial. Blueberries don’t like “wet feet” — soggy soil can cause root rot. Avoid planting in low-lying areas where water collects. If your soil is heavy clay, consider planting in raised beds filled with acidic, well-draining soil mix.


2. Sunlight: The Key to Bountiful Berries

Blueberries do best in full sun, requiring at least 6 hours of direct sunlight daily during the growing season. More sun typically means sweeter, larger berries and healthier plants. If you only have a partially shaded spot, your plants may still grow but expect fewer fruits.


3. Surroundings: Protect Your Blueberries

Think about your blueberry bushes when they’re fully grown. Are there tall trees nearby that could cast heavy shade? Is the location sheltered from strong winds, which can dry out the plants and damage flowers?

Also, avoid planting near large trees or shrubs with aggressive roots that could compete for nutrients and water.


4. Spacing: Room to Grow

Blueberry plants spread by roots and branches, so giving them enough space helps avoid competition and disease.

Spacing guide:

  • Highbush blueberries: 4–6 feet apart

  • Lowbush varieties: 12–18 inches apart (often grown as groundcover)

  • Rabbiteye blueberries: 6–8 feet apart

Rows should be spaced about 8 to 10 feet apart for easier access and air circulation.


5. Plan for the Future

Blueberries are perennial plants that can produce for 20 years or more. Start with a manageable number but leave room to add more bushes or complementary crops like strawberries or raspberries.

Planning ahead ensures your berry patch can grow with your enthusiasm—and keep your harvests bountiful.


Ready to Plant? You’re Almost There.

Choosing the right spot is one of the best investments you can make for your blueberries’ long-term health and productivity. With proper planning and expert guidance from 1st Choice Fertilizer, you’re well on your way to growing a thriving blueberry patch that rewards you year after year.

How to Plant Blueberries 

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Establishing healthy blueberry bushes starts with how—and where—you plant them. While blueberries are relatively low-maintenance once established, giving them a strong start is key to years of vibrant growth and abundant berry harvests.


Getting Started: Prep Before You Plant

If you have bare-root blueberry plants, soak the roots in a bucket of water for 1–2 hours (but no more than 6) before planting. This keeps the roots hydrated and ready to absorb nutrients. Avoid letting roots dry out or freeze before planting.

For potted blueberry bushes, water well before transplanting, and keep them shaded if you can’t plant immediately.


Step-by-Step Planting Guide

Dig a Proper Hole
Blueberries need acidic, well-draining soil. Dig a hole about twice as wide and just as deep as the root ball or root system. Blueberry roots are shallow and fibrous, so don’t plant too deep—keep the crown of the plant at or just slightly above soil level.

Enrich the Soil
Blueberries thrive in acidic soil (pH 4.5–5.5). Amend your planting soil with peat moss, pine bark, or our Coco-Fiber Growing Medium to increase acidity and improve drainage and aeration. Avoid heavy clay or alkaline soils unless amended.

Position Your Bush
Place the blueberry plant in the hole, spreading roots gently. Backfill with the amended soil, lightly firming to remove air pockets but avoid compacting too much.

Create a Watering Basin
If planting on sloped ground, build a small berm around the hole to help retain moisture. Blueberries prefer consistently moist soil but not waterlogged conditions.


After Planting: Water, Mulch, and Protect

  • Water thoroughly—about a gallon per plant—to settle the soil around the roots.

  • Mulch with 2–3 inches of pine needles, wood chips, or bark mulch to retain moisture, regulate soil temperature, and suppress weeds.

  • Keep mulch a few inches away from the plant’s base to prevent rot.

  • Avoid fertilizing immediately after planting; wait until the plant shows new growth in spring, then apply an acid-loving plant fertilizer such as 1st Choice Fertilizer’s Berry Booster.


Special Planting Tips for Blueberries

  • Blueberries have shallow, fibrous root systems and prefer acidic, well-drained soils—avoid planting too deep or in heavy clay.

  • Avoid planting near trees or shrubs with invasive roots that could compete for nutrients and water.

  • Consider planting in raised beds if your native soil drains poorly or has a high pH.


How to Plant Potted Blueberry Bushes

  • Water your plant well before transplanting.

  • Gently remove the bush from its pot, loosening any roots circling the root ball to encourage outward growth.

  • Plant immediately and water deeply after planting.

  • Keep newly planted bushes shaded for a few days if the weather is hot or windy to reduce transplant shock.


Final Tip: Mulch and Monitor

Mulching is key for moisture retention and weed control. Check soil moisture regularly, especially during dry spells, to keep roots consistently moist but not soggy.


You’re On Your Way

With careful planting and proper care, your blueberry bushes will flourish for years to come. And with 1st Choice Fertilizer’s expert products and guidance, you’re fully equipped to grow a healthy, fruitful blueberry patch from the very start.

How to Prepare Soil for Planting Blueberries

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Before your blueberry bushes ever touch the soil, proper preparation is essential for long-term success. Healthy, well-prepared soil means healthy roots—and healthy roots lead to strong, fruitful plants.

Whether you’re planting in spring or fall, preparing your soil ahead of time gives your blueberry bushes the best possible start. Here’s what you need to know.


Why Soil Preparation Matters

The right soil environment allows your blueberry plants to:

  • Access essential nutrients

  • Maintain proper moisture levels

  • Develop a shallow but extensive root system

  • Thrive in acidic conditions (pH 4.5–5.5)

  • Resist disease and environmental stress

We recommend testing your soil before planting and again annually to monitor pH, nutrient levels, and moisture. You can use our 1st Choice Digital Soil Meters for quick, at-home readings or send samples to your local Cooperative Extension for detailed analysis.


Understanding Soil Types for Blueberries

Your native soil affects how much amending you’ll need. Blueberries thrive in acidic, well-draining soil. Here’s what to look for:

Clay or Silt Soils
Heavy, poorly drained soils can suffocate blueberry roots and lead to rot. If your soil is clay-heavy, you’ll need to improve drainage by adding organic matter or planting in raised beds.

Loam Soils
Loam is ideal for blueberries if it’s slightly acidic. It holds moisture well but drains excess water, providing good conditions for healthy roots.

Sandy Soils
Sandy soil drains quickly and is naturally acidic, which is good for blueberries, but it doesn’t hold moisture or nutrients well. Amend with organic matter to improve moisture retention.


When to Prepare the Soil

Prepare soil when the ground is workable—not frozen or waterlogged. Early spring or fall is ideal. For spring planting, start amending in fall to allow materials to integrate and improve soil structure.


What to Add to Your Soil

Blueberries need acidic, nutrient-rich, and well-draining soil. These amendments help create the perfect environment:

  • Peat Moss or Sphagnum Moss – Excellent for acidifying soil and improving moisture retention.

  • Pine Bark or Pine Needles – Natural mulch that helps maintain acidity and improves soil texture.

  • Compost – Feeds soil microbes and boosts fertility.

  • Sulfur or Aluminum Sulfate – To lower pH if soil is too alkaline.

  • Sand – To improve drainage in heavy soils.

Avoid lime or other alkaline amendments—they raise pH and can harm blueberries.


How Organic Matter Helps Different Soils

In sandy soil:
Organic matter binds particles to retain moisture and slow nutrient loss.

In clay or silt soil:
Organic matter breaks up dense soil, improves drainage, and encourages root expansion.

In poor soils:
Compost and natural amendments restore microbial life and boost nutrient availability for healthier plants.


Your Soil, Your Success

Great soil preparation is one of the most important steps you can take for your blueberry bushes. It leads to stronger growth, better yields, and healthier plants year after year.

Fertilizing Blueberries for Healthy Growth and Fruit Production


(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Fertilizing blueberries is one of the best ways to improve soil health and ensure your bushes get the nutrients they need—especially nitrogen, which supports healthy leafy growth early on. But blueberries have some unique needs, particularly their preference for acidic soil and balanced feeding.

Since not all soils or blueberry varieties need the same nutrients, testing your soil before fertilizing is essential. Whether you’re planting new bushes or caring for mature plants, soil testing helps you apply the right amount—and the right type—of fertilizer.


Why Fertilize Blueberries?

Fertilizer is more than “plant food”—it supplements your soil with vital nutrients that help blueberries grow strong and produce abundant fruit.

The three key macronutrients are:

  • Nitrogen (N): Promotes vigorous leafy growth and overall bush development

  • Phosphorus (P): Supports root growth and flower formation

  • Potassium (K): Boosts fruit quality and disease resistance

These nutrients appear as N-P-K ratios on fertilizer labels. For blueberries, it’s important to use fertilizers formulated for acid-loving plants with balanced nutrients and micronutrients like iron and magnesium.


Always Test Before You Fertilize

Soils vary widely in nutrient content and pH. Over-fertilizing can harm blueberries and the environment, while under-fertilizing limits growth and yield. We recommend using a 1st Choice Digital Soil Meter or sending soil samples to your local Extension office for accurate testing.

Knowing your soil’s pH and nutrient levels allows you to choose the right fertilizer—whether a slow-release organic granule or a water-soluble formula designed for quick uptake.


Fertilizing Young Blueberry Bushes

Newly planted blueberry bushes in good soil often need little to no fertilizer the first season. If growth is slow or leaves look pale, supplement with an acid-loving plant fertilizer.

Our 1st Choice Blueberry Starter Formula is a water-soluble option that provides balanced nutrients to help young bushes establish strong roots and foliage.


Fertilizing Mature Blueberry Plants

Once your bushes start producing fruit (usually 2–3 years after planting), their nutrient needs increase, especially nitrogen and potassium.

Apply fertilizer in early spring and again after harvest to support continued growth and fruit development. 1st Choice Blueberry Boost Granules are specially formulated for mature bushes and easy to apply around the root zone.


When to Fertilize Blueberries

  • First application: Early spring, just as new growth begins

  • Second application: After harvest in late summer or early fall

⚠️ Avoid fertilizing late in the season (after August) to prevent tender new growth that may not harden off before winter.

Always follow label directions and local regulations for fertilizer use to protect your plants and the environment.


Different Blueberry Varieties, Different Needs

Blueberries generally have similar nutrient needs, but some varieties can be more sensitive to pH and nutrient imbalances. Northern highbush, rabbiteye, and southern highbush types may require slightly different care.


Don’t Forget Micronutrients

Alongside N-P-K, micronutrients like iron, magnesium, and calcium are essential for blueberry health. For example, iron deficiency causes yellowing leaves (chlorosis), common in alkaline soils.

If micronutrient deficiencies appear, consider foliar sprays or soil amendments like 1st Choice Acid-Grow Mineral Mix  Earth-Care Prime 5-8-8 to correct imbalances during the growing season.

Pruning Blueberry Bushes

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Pruning your blueberry bushes is essential for maintaining healthy growth, increasing fruit production, and encouraging a strong structure that lasts for years. Proper pruning helps remove old wood, stimulate new growth, and shape your bushes for maximum yield.


Why Prune Blueberry Bushes?

  • Survival: Reduces stress on transplanted or young bushes by balancing root and top growth.

  • Stimulation: Encourages vigorous new shoots that produce more fruit.

  • Shape & Structure: Maintains an open, well-ventilated canopy to reduce disease and maximize sunlight.


Basic Pruning Principles for Blueberries

  • Timing: Prune during late winter or early spring while plants are dormant (before bud break).

  • Remove: Dead, damaged, or weak canes and any crossing or inward-growing branches.

  • Shape: Aim for an open center or vase shape to improve air circulation and light penetration.

  • Cut: Make clean cuts at the base of old canes, or just above healthy lateral buds for new growth.


Pruning Techniques

Cane Renewal:
Blueberries fruit best on 1- to 4-year-old wood. Each year, remove about one-third of the oldest canes at ground level to encourage new, productive shoots.

Thinning:
Thin crowded areas to prevent shading and improve airflow, reducing disease risk.

Heading Back:
Cut back overly long shoots by about one-third to stimulate lateral branching and more fruiting sites.


Seasonal Pruning Calendar for Blueberry Bushes

Watering Blueberry Bushes

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

Blueberries thrive in consistently moist, well-drained soil but can suffer if either too dry or too wet. Unlike some fruit trees, blueberries have shallow root systems that need steady moisture—especially during establishment and fruit development.


Watering Tips for New Blueberry Plants

During the first growing season, keep the root zone evenly moist but never soggy. Blueberries typically need about 1 to 2 inches of water per week, whether from rainfall or supplemental irrigation.

  • If your area averages 1 inch of rain every 7 to 10 days, you may not need to water often.

  • During dry spells, water deeply and slowly to soak the soil about 6–8 inches deep.

  • Use drip irrigation or soaker hoses to avoid wetting foliage, which helps reduce disease risk.

  • Mulching around bushes with pine needles or wood chips helps retain moisture and keeps roots cool.


Watering Established Blueberry Bushes

Once established (after the first 1–2 years), blueberries still require regular watering, especially during flowering and fruit set:

  • Aim for consistent moisture, watering about once or twice per week during dry periods.

  • Avoid waterlogging; blueberries do not tolerate standing water and poorly drained soils.

  • Shallow, frequent watering leads to weak roots—prefer deep, thorough watering instead.

  • Adjust watering frequency based on soil type: sandy soils drain quickly and need more frequent watering, clay soils retain moisture longer.


Special Considerations

  • Blueberries prefer acidic soil with good organic matter that holds moisture well—using a fertilizer like 1st Choice Fertilizer can improve soil moisture retention while providing nutrients.

  • Create a shallow basin around each bush to help catch water and direct it to the roots.

  • In colder climates, remove basins before winter to prevent ice buildup that can damage roots.

  • During hot, dry summers, check soil moisture frequently—mulching and shade can help reduce evaporation.


Local Conditions & Water Restrictions

Keep an eye on local watering regulations and drought advisories. Use water wisely and adjust irrigation schedules as needed to conserve resources without stressing your plants.


Summary

Stage Watering Frequency Notes
New Plants (Year 1) Deep watering every 7–10 days Keep soil evenly moist, not saturated
Established Plants Deep watering 1–2 times per week Increase during bloom and fruit development
All Stages Avoid wetting foliage; mulch heavily Use drip or soaker hoses; adjust for soil and weather

Blueberry Harvest and Storage

(From the “How to Grow Blueberries” Series by 1st Choice Fertilizer)

After months of nurturing your blueberry bushes, harvest time is the sweet reward! To get the most from your crop, it’s important to know when your berries are ripe and how to store them properly to enjoy their fresh flavor longer.


When Will My Blueberry Bush Start Producing?

Blueberry bushes generally begin producing fruit 2 to 4 years after planting, with yields increasing as the plants mature. Varieties, climate, and care all influence when and how much fruit you can expect.


Recognizing Ripe Blueberries

Blueberries are ripe when they have developed a uniform deep blue color all around (no red or green spots) and have a slight dusty bloom on the skin. They should be plump and detach easily from the bush with a gentle tug—ripe berries fall off naturally when you shake the branch lightly.

Harvest typically occurs from late spring through summer, depending on your variety and region. Harvest often spans several weeks, as berries ripen gradually.

Typical yields per mature bush vary widely but can range from 5 to 15 pounds per season depending on cultivar and growing conditions.


How to Harvest Blueberries

  • Pick berries carefully by hand to avoid crushing.

  • Harvest every 4–7 days to gather berries as they ripen.

  • Use shallow containers to prevent crushing fruit at the bottom.

  • Avoid harvesting when berries are wet to reduce mold risk.


How to Store Blueberries for Maximum Freshness

  • Sort through berries and discard any soft, moldy, or damaged fruit.

  • Store fresh blueberries unwashed in a breathable container (like a vented clamshell or shallow bowl covered with plastic wrap) in the refrigerator.

  • Blueberries keep best at 34°F to 38°F with high humidity.

  • Wash berries just before eating or using to avoid premature spoilage.

  • Fresh berries typically last up to 10–14 days refrigerated.


For Longer-Term Storage

  • Freeze blueberries spread on a baking sheet to prevent clumping, then transfer to airtight freezer bags or containers.

  • Frozen blueberries maintain quality for up to 12 months.

  • You can also preserve blueberries by drying or canning for extended shelf life.
