I have recently bought two passiflora incarnata plants, both of them being only a year old in 4 inch pots. I spoke with several growers of this plant and some told me I should wait till spring to plant because the plants are so young. Some told me to get them in the ground and mulch heavily and cover when the frosts came. We haven't had a frost here yet but it is getting down in the 50's maybe a little colder at night. Can I plant them and then just cover them up to protect them from frost? And if I do plant them now will the roots take hold and survive? And comments or suggestions would be great. Thanks. ;)
