The Q&A Archives: What is causing browning?

Question: I have a Phygelius(Sunshine) plant (whose leaves are yellowish/light green) turn brown JUST ON THE TIPS. The plant is in full sun until about 1-2 PM, and is watered consistently on a daily basis. It bloomed in late summer and the blooms seem OK. I would like to prevent the leaf tips from turning brown because it ruins the appearance of the plant. Please advise.
Many thanks.

Answer: Browning leaf tips can indicate low humidity or salt build up in the soil. If your sunshine plant is next to a wall or foundation of your house, the air may be extremely dry. You can try misting the plant or hosing it off to increase humidity during the hottest summer days. Use a liquid rather than a granular fertilizer to help prevent salt build up in the soil. You can also pinch or prune off the affected leaves; new leaves should be healthy and without brown tips.

Best wishes with your garden!
