i personally would just watch this yearr, draw a diagram of where/what everything is, and handle it as appropriate as the year progresses. does that make sense? you know, like for azaleas, they should be pruned here in the south in the next month or so. not later than late june. (when the last bloom drops). for bulbs, when they come up, are they over crowded? dig them up in fall to divide and replant in the spring. and so on. i hope this helps, that is how i've always handled gardens that get neglected.
