planted canna bulbs too early

Question

I planted my overwintered canna bulbs yesterday and I see that tonight we might get frost (Annapolis, MD). Should I try to protect the planting area with a tarp or blanket?

Answer 1

I would add a 2- to 4-inch layer of mulch. For more information on spring bulb frost protection, please visit the following link:
