On our 4 1/2 acre property we have about 50 or so Juniper trees. Three are right next to the house. I want to plant something under the trees, but the only thing that grows so far are Irises. I planted some Vinca, but the Juniper trees seem to drain all the water and moisture out of them. And what can I do to get rid of the juniper bugs? Anyone know what I can plant under the trees?
