Troubleshooting
spear-leaved arrowhead vine problems — and how to fix them
spear-leaved arrowhead vine (Syngonium hastifolium) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from overwatering
The most common cause of decline. Yellowing lower leaves and mushy stems at the base indicate soggy soil. Allow the top inch to dry before re-watering and ensure the pot has drainage holes.
Brown leaf tips
Usually caused by low humidity or fluoride/chlorine sensitivity in tap water. Use filtered or room-temperature water and raise humidity to 60%+ to alleviate the issue.
Spider mites in dry conditions
Fine webbing on leaf undersides and stippled foliage signal spider mites. Increase humidity, wipe leaves with a damp cloth, and treat with insecticidal soap or neem oil spray if infestation persists.
