Brown spot on Dutchman’s Pipevine

Zone 33803 | Cindy Alexander added on April 26, 2018 | Answered

2 pipevine questions: First, I planted a Dutchman's Pipevine about 1 month ago. It continues to get Brown spots on the leaves, but not all leaves. It's in full sun in central Fl. It's mulched and watered by soaker hose. Is it fungal, bacterial, or just bad soil? (See photo of 3 leaves) Second, I planted what was supposed to be wooly pipeline 1 wk ago in partial sun. Now it's starting the same pattern (see photo of 2 leaves). Help!

It would seem, since these are affecting two of the same species, that there is a fungal infection present in the soil. You will have to cure this, if it is curable. This can be done by applying dolomitic lime, and wettable sulfur to all of the infected areas. This will kill off any infection that is able to be killed, and bring the soil back to proper pH. After about 2 weeks, you should be able to replant.

Here is an article that will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/vines/dutchmans-pipe/growing-dutchmans-pipe-vine.htm
