How do i grow Blueberries?
Prepare the soil by digging in plenty of Healthy Earth Instant Claybreaker, Planting Compost, Peat Moss and Manutec Sulphur.
Blueberries need an acidic soil with a pH of 4.5-5.5 (just like Azaleas and Rhododendrons). You will probably need to add approx. 300g per m of Sulphur – thoroughly dug in. Test the soil with a home pH Test Kit until you achieve the desired acidity. Thereafter reapply Sulfur every Autumn.
If you are growing in pots, use large ones approx. 40-50cm tall and wide. Plant into Azalea and Camellia Potting Mix and feed with Healthy Earth Fertiliser 3 times a year – Spring, Summer and Autumn. Add 100g/m2 Sulphur each Autumn to maintain the required soil acidity.
Plant year round.
Mulch heavily with Sugar Cane or Pea Straw and water once or twice a week – keep moist, not waterlogged.
Flowers and leaves appear in Spring while the berries ripen from December through mid-February. The older the bush the longer you harvest. Don’t forget the bird netting! Blueberries don't have any pest and disease problems other than hungry birds!
