Couple of Pruning questions
Hydrangea Macrophylla - I left the old brown mophead flowers all winter. There are now green shoots coming below the old flowers. Can / should I prune to just above the new growth now or leave be?
Purple loosestrife - Again, I kept the skeletal form over the winter. No sign of growth yet this spring. Given how invasive it supposedly is I'm guessing it's pretty tough, so I assume it would be OK to pretty much cut right back to the ground now?
