Can someone please tell me how often do I water Boxwood. Specifically TRUEDWARF BOXWOOD (Buxus sempervirens "Suffruticosa") I purchased 2 little beauties today and planted them each in a cement urn on the N. side of my home. One will get sun in the am (east) and the other will get the sun in the pm (west) I planted them in 30% rotted mulch/70% seasoil. I added some mulch on the top as well. They have excellent drainage. I would like to know how wet/dry to keep the soil? Thanks everyone!
