Blueberry seeds from a certified organic blueberry farm in Kentucky, USA. Northern and Southern blueberry seed mix. BLUEBERRY PLANTS ARE EASY TO GROW FROM SEEDS These seeds have been stratified to get the highest possible germination rate. They are NON GMO. Blueberry seeds are slow germinators, the first seeds will probably start to germinate in about a month, and finish germinating over the next 2-3 months. Blueberries should be started in a separate container from other varieties that germinate quickly because they can take longer to sprout up.

Storing & preserving
Refrigerate dry and unwashed; use within a few days.
- Freeze: Freezes well raw; spread on a tray first so pieces stay loose.
- Preserve: Make jam or freezer jam; water-bath can high-acid preserves.

When to feed, prune & water
Protect ripening blueberries from birds
Protection- Routine careNet the bushesstrong evidence — extension confidence
Drape bird netting over the bushes or a simple frame as the berries start to ripen, securing it around the edges so birds cannot get underneath. Quality netting can be reused for several seasons.
Prune blueberries while dormant
PruningUnusual this time of year.
- Routine careAnnual dormant pruningstrong evidence — extension confidence
In late winter before buds swell, remove dead, diseased, and broken wood plus weak twiggy growth, and on mature bushes (about five years and older) cut out a few of the oldest canes to renew the plant. Open up the center for light and air to improve fruit size and reduce disease.
Something looks wrong?
Describe what you see on your blueberryand we'll rank the likely causes — most likely first, least-invasive fix first.
Acidify soil for blueberries (and fix yellowing leaves)
Deficiencymoderate- CulturalLower and maintain soil pHstrong evidence — extension confidence
Blueberries need an acidic soil pH of about 4.5 to 5.5, and yellowing between the veins usually means pH is too high to take up iron. Test the soil and, well before planting, work in elemental sulfur or acidic sphagnum peat per the soil-test recommendation to bring pH into range, then mulch with an acidic material like pine bark or sawdust.
- OrganicUse acidifying fertilizermoderate evidence — extension confidence
Feed with a fertilizer formulated for acid-loving plants per the label rather than general garden fertilizer, which helps maintain low pH over time. Avoid high-pH irrigation water and lime near the plants.
Iron deficiency (interveinal chlorosis)
Deficiencymoderate- CulturalTest and address soil pHstrong evidence — extension confidence
Iron is present but unavailable in high-pH soils, so test soil pH and, for the affected bed, lower pH toward the crop's preferred range (especially important for acid-loving blueberries) rather than just adding iron.
- OrganicUse chelated iron for a quick correction· every 2 wksmoderate evidence — extension confidence
A foliar spray or soil drench of chelated iron can green up new growth per the label; soil-applied ferrous iron quickly oxidizes and becomes unavailable in high-pH soil, so chelate plus pH management works best.
Spotted wing drosophila on blueberries
Pestmoderate- CulturalHarvest often and sanitize· every 2 daysstrong evidence — extension confidence
This vinegar-fly lays eggs in ripening fruit, so pick frequently and completely, removing and discarding overripe and dropped berries to deny it breeding sites. Chilling harvested berries promptly stops larvae from developing.
- OrganicMonitor and spray if present· every 1 wkmoderate evidence — extension confidence
Hang a vinegar or yeast-bait trap to detect adults, and if flies are caught as fruit starts to color, apply a labeled spinosad product per the label, rotating chemistry to avoid resistance. Time sprays to begin when berries first turn pink.
Blueberry mummy berry
DiseasemoderateUnusual this time of year.
- CulturalRemove mummies and disrupt the cyclestrong evidence — extension confidence
Mummy berry is a fungal disease that overwinters in mummified berries on the ground; rake up and remove fallen mummies and cover the soil under the bushes with a few inches of fresh mulch before spring to bury them. Promote air movement and avoid prolonged leaf wetness.
- ChemicalFungicide for severe cases· every 10 daysmoderate evidence — extension confidence
Where the disease is recurring and severe, apply a labeled fungicide per the label beginning at bud break and through bloom when infection risk is highest. Combine with sanitation and mulching for the best control.
