How to grow blueberry plants, from purchased blueberries

Growing blueberry plants from store-bought blueberries can be a fun and rewarding project. Here’s a simplified step-by-step guide to help you get started:

Materials Needed:

  • Fresh, ripe blueberries
  • Paper towel
  • Water
  • Small containers or seed trays
  • Potting soil
  • Large pots or a garden bed
  • Watering can
  • Mulch (optional)


1. Extracting and Preparing Seeds:

  • Select Blueberries: Choose plump, ripe blueberries for seed extraction.
  • Crush and Rinse: Gently crush the blueberries to release the seeds. Place the crushed berries in a bowl of water. The seeds will sink to the bottom.
  • Separate Seeds: Pour off the pulp and any floating seeds, then collect the seeds at the bottom. Rinse them thoroughly with water.
  • Dry Seeds: Spread the seeds on a paper towel and let them dry for a few hours.

2. Preparing for Planting:

  • Chill Seeds: Place the seeds in a damp paper towel, then put the towel in a plastic bag. Store it in the refrigerator for 60-90 days to mimic winter conditions (stratification).

3. Planting Seeds:

  • Prepare Containers: Fill small containers or seed trays with potting soil.
  • Sow Seeds: Scatter the seeds on the soil surface, then cover them lightly with a thin layer of soil.
  • Watering: Gently water the soil to keep it moist. Use a spray bottle to avoid washing away the seeds.
  • Provide Conditions: Place the containers in a warm, sunny location with temperatures between 65-75°F (18-24°C).

4. Germination and Early Care:

  • Germination: Be patient, as blueberry seeds can take several weeks to germinate.
  • Water Regularly: Keep the soil consistently moist but not waterlogged.
  • Thin Seedlings: Once seedlings are a few inches tall, thin them out to prevent overcrowding.

5. Transplanting:

  • Prepare Larger Pots/Garden Bed: Choose a sunny spot with acidic, well-draining soil (pH 4.5-5.5). Amend the soil with organic matter if necessary.
  • Transplant Seedlings: Gently transplant the strongest seedlings to larger pots or directly into the garden, spacing them 3-4 feet apart.

6. Ongoing Care:

  • Watering: Water regularly, keeping the soil evenly moist but not soggy.
  • Mulching (Optional): Apply mulch around the base of the plants to retain moisture and suppress weeds.
  • Feeding: Use a fertilizer designed for acid-loving plants, following the manufacturer’s instructions.

7. Maintenance:

  • Pruning: Prune the plants in late winter or early spring to remove dead or weak branches and encourage new growth.
  • Protection: Protect young plants from pests and harsh weather.

8. Harvesting:

  • Wait for Maturity: Blueberry plants typically take 2-3 years to produce fruit.
  • Harvest: Pick the berries when they are fully ripe and deep blue.

By following these steps, you can successfully grow blueberry plants from store-bought blueberries and enjoy fresh, homegrown berries in the years to come.
