Answer: Browning leaf edges can indicate overwatering, over fertilizing, dry air or chemicals in the water. Try watering throughly and then letting the top of the soil dry out before watering again. Hold off on fertilizer for now and see if the new growth becomes affected or if just the oldest leaves are showing the crispy brown edges. If new growth shows the same symptoms you may want to repot with fresh potting soil or use distilled or bottled water for you grape tree. Best wishes with your plant!
