โ๏ธ Missed
- Add a liquid acid-loving fertilizer to the substrate.

- โ Fertilizer for azaleas / rhododendrons
- โ Fertilizer for acid-loving plants
- โ Organic fertilizers: blood and gram, coffee grounds
- โ Do not use fertilizers with nitrates!
Fertilization schedule:
Granular fertilizer before flowering
Fertilizer for recovery
Slow-release fertilizer (Osmocote)
๐ Pollination
Blueberries are self-fertile , but...
Why is it worth growing 2 varieties?
- ๐ซ Larger fruits
- ๐ฆ Bigger harvest
- ๐๏ธ Longer harvesting season
- ๐ Bees pass through the bushes and pollinate
Recommended pairs:
- Sunshine + Biloxi - a winning combination!
- Sunshine + Sharpblue
- Titan + Rebel
โ๏ธ Pruning
Years 1-3: Minimal pruning
- Remove only broken or diseased branches.
