fertilizer burn on Rose
Quick answer
If your Rose has fertilizer burn, the most likely cause is: Applying too much synthetic, high-nitrogen fertilizer or applying it to dry soil causes salt buildup that draws moisture out of the roots. Symptoms include browning and crisping of leaf margins (edges) and stunted, scorched-looking new growth.
Start here:
- 1. Immediately flush the soil around the base with copious amounts of water to leach out excess salts
- 2. Trim severely burned foliage to improve appearance
