How long does it take bare root plants to "wake up" after they've been put in? I planted a mixture of bare root ferns about a month ago, and have been keeping the area watered, but haven't seen any growth yet. I also just planted some asparagus today, and I don't know how long it will be before I see any growth from them? They arrived in the mail about a week ago and I don't think I stored them properly before putting them in today, so I'm worried they may already be dead, and am not sure at what point I should give up hope and re-plant the bed with something else. They seemed dried out, but I did clip one of the roots off to see what it looked like inside, and it was white and fleshy...is that...good? Thanks!
