well your best bet isnt really to put them outside when they are seedlings, only a few inches tall. you should grow your plants for a little while indoors then bring them outside so they have a better fighting chance against the wind and the great outdoors. there is another few solutions though, put it in a group of small trees and clear a spot in the middle, alot less wind. another idea is make a small greenhouse, slap a couple 2x4's together and staple some plastic on there and you got yourself a greenhouse. hope that helps
