I planted six blackberry plants last year and the fire burned the stalks off. I was afraid they were totally dead. Five of the six have put out new growth. I don't think we'll get blackberries from them this year, but at least I won't have to buy more to replace these. Maybe the sixth one with put out soon.
The black on the dirt makes it necessary to wear closed in shoes rather than sandals to avoid ruining socks and spending a lot of time trying to get soot out of my toenails!
