O Ok i thought that as you with the powder stuff, you dont need to keep using it. They shoudl be ok past week 4 and fend for themself. I would train them not top because toping will cause a shock and might weaken them.
And thanks for the reply clonemeister. Hopefully that will be what saves them, they are surrounded by trees and dont get direct sunlight for the entire day. The storms we had last night are another story, i'll go check on them later today and tie them down if they're still there. Durn tornado weather
