每日吃瓜

I have had many trees in the past, and since I thought they could be kept indoors, they all died. I’ve started growing plum seeds, and they are about 3 “ tall now. Should I keep the seedlings outside even though the nighttime temperature drops to low 40’s - high 30’s here in Dallas? Or, should I keep them indoors until next spring?
Thanks

I dont know the species or the climate. But where I live all seedlings that sprout in authumn are dead by spring no matter species.

If you dont get frost my best guess is that protected outside gives you the best chanse.
