yellow leaves on Bourbon Vanilla
Quick answer
If your Bourbon Vanilla has yellow leaves, the most likely cause is: Vanilla planifolia's foliage is susceptible to foliar disease whenever the air around the vine is stagnant, the leaves stay wet, and temperatures run cool — the same wet-but-cool, still-air combination that the plant otherwise needs to avoid at its roots. The book lists this as the only foliar issue the species shows in cultivation, and notes that pests are not a typical problem on Vanilla planifolia.
Start here:
- 1. Move the vine to a spot with genuinely warm conditions and good air movement so the foliage dries quickly after watering or misting, and avoid letting water sit on the leaves overnight.
- 2. Switch to an airy, porous orchid medium such as sphagnum moss or fine bark so the root zone never stays cold and soggy at the same time the foliage is wet, since that combination drives the foliar problems this species is prone to.
