Need Advice Redoing Lasagna Bed
From reading all the great advice on this forum, I think I know what I can do, but I just want to make sure I'm on the right track.
Four years ago (?) I redid a grassy/weedy area and did the lasagna method before planting. When I did an inspection today, it appears it's sunk enough that I should redo it. My two rose bushes are showing their roots above the soil at least two inches, maybe three.
In the bed I have two rose bushes, 5-6 daylilies (which are in a lower spot now than the roses), liatris, Royal Candles speedwell, a low creeping ground cover with purple flowers ( the name escapes me) and some type of phlox ( again the name escapes me), and a bunch of irises.
As far as I know all of these can be dug up, kept in a holding bed while I build up the area in question, and then replant the works without doing much harm to the plants.
It can be done, right? How long can things be in the holding bed before it's too late to move them back? Any and all advice appreciated :)
