This past winter I lost a large 5 gallon-size Passiflora Manta I had grown into a specimen plant over several years. I now have 2 plants recently transferred to 3 gallon containers. It seems winter was the downfall. I would really like to hear how dry they can be during the winter months. I grow my plants outside from spring to fall and winter them indoors. Looking forward to any advice you can offer. Thanks.
