These small, delicious berries are regarded as “superfoods” because they are particularly high in vitamins and antioxidants. They need an acidic soil, and to guarantee fruit you should grow two different cultivars together.
When to plant: Mid-autumn.
At their best: Summer.
Time to complete: 1 ½ hours
You will need: Two blueberry plants, two large pots, broken clay pot pieces, Ericaceous soil mix and fertilizer, mulch – such as bark chippings, rainwater.
Plant in large pots
Place broken clay pieces in the base of each large pot and part fill with ericaceous soil mix. Plant the blueberry plants at the same depth as they were in their original pots, and fill in around the root balls with more soil, to within 2in (5cm) of the rim.
Add fertilizer
To ensure a good crop, add a slow-release ericaceous fertilizer to the soil, following the instructions on the package. Most slow-release fertilizers last for a limited period, so reapply as specified. Don’t use non-ericaceous fertilizers, as these could harm your plants.
Water and mulch
Because tap water often tends to be alkaline, use rainwater to water the plant thoroughly. Then place a mulch of bark chippings over the soil to help retain moisture. Water daily with rainwater. The berries will ripen over a few weeks; pick as required.
