How to Raise Blueberry Plants Indoors

Blueberry bushes are attractive container plants, and with enough space and the right care, are easily grown indoors or in enclosed sun rooms or patios. Choose small dwarf types in two to three different varieties in order to ensure cross-pollination and berry production. Consider compact bush cultivars such as Sunshine Blue and North Blue that are well suited to container gardening. Blueberries are in the same family as rhododendrons and azaleas and require similar growing conditions. Proper soil pH is crucial to blueberry cultivation, as the plants need an acidic soil with a pH range of 4.5 to 5.5.
