If you have peonies, iris, hostas, etc. (like I do), hopefully you cleared away last years stalks. If not, do it now, being careful to avoid damaging the new shoots. Also consider putting up support fencing now before your peonies get too large, and definitely before they develop their heavy blooms (which would otherwise cause them to droop to the ground). I use a 2 foot high green fence (which is almost invisible in the picture below) for part of mine and two shortened tomato cages for a small group to the right of the tree. The tree came up unnoticed in the bed about 40 years ago (but is vary noticeable now).
