The first, and most important step to growing blueberries is making sure you have the right spot.
Like most fruits, blueberries do best in full sun. They do tolerate shade, but they won't produce nearly as much fruit as they would in full sun. They also prefer moist, well-drained soil that's rich in organic matter. If you have heavy clay, you'll definitely want to amend it with compost, peat moss, or similar materials before planting blueberries.
What makes blueberries different than most fruits is they need soil with an acidic pH: ideally between 4.5 and 5.5. If you have neutral or alkaline soil, it's best to amend it with soil sulfur before planting your blueberries.
