Sad blueberries- what to do?
I have five rabbiteye blueberry bushes planted out in a sunny spot. They've been there about a year, and they've never thrived. They haven't grown much and they don't have the number of leaves they ought to.
The soil is naturally sandy with a few inches of black topsoil. I some Black Kow into the plot when I prepared it. Ever since I planted, I have been mulching with pine needles and throwing some azalea fertilizer around them every few months. I keep the area watered but not wet.
I've got some highbush blueberries in Earth Box containers that grow like mad, but these guys are barely hanging on.
What's wrong and what can I do?
