passion flower trunk is split

Question

The main trunk is split. Is there anything we can put over the splits? I hate to lose the vine…it gives a lot of privacy.

If the leaves are also yellowing and falling off, a split in the trunk can be a sign of fusarium wilt, a fungal disease. See these articles for more:

If there is no disease, then it's best to leave the trunk alone because it will recover better if nothing is put over the split.
