These small, delicious berries are regarded as superfoods because they're particularly high in vitamins and antioxidants. Here's how to grow these acid-loving plants in containers.
When to Plant: mid-autumn
At Their Best: summer
Time to Complete: 1 1/2 hours
Place broken clay pieces in the base of each large pot and part-fill with 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 2 inches of the rim.
To ensure a good crop, add fertilizer to the soil, following the instructions on the package. Most slow-release fertilizers last for a limited period, so reapply as specified.
Because tap water sometime tends to be neutral or 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.
If you live in a region that's colder than USDA Zone 6, heel your pots into the ground to overwinter.
