The Bracken Fern came looking dead, 4 skinny sticks, no rootlets. The Royal fern has one up; the Walking Fern has three up and is a nice green, the moss seems to support it well; the christmas Fern and the Cinnamon Fern have two up. I planted all FIVE fern the day after received, all on same day in large pots to protect from our squirrels! PLUS, placed chicken wire and a brick on top to keep out the squirrels too! Nervous with the bracken, please give me a timeline on how long it takes for them to grow?
