A: If you have amended your soil every year with compost, it may have too much organic matter in it. This would make it drain poorly, and that could lead to plant disease or decline. Your county Extension office can facilitate a soil test for organic matter. It costs around $10. If your garden soil seems a bit spongy, my recommendation is to add expanded slate (PermaTill). Many Ace hardware stores carry it.
Q: Would a ‘Sharpblue’ blueberry bush work well with a ‘Sunshine Blue’ blueberry? Dinny Gujral, Peachtree Corners
A: Both of these blueberries are Southern highbush varieties. They bear fruit earlier than our common rabbiteye blueberries. They will partially pollinate themselves individually, but they fruit a lot better with a different variety nearby. These two make a good combination.
