Trumpet Vine And Other Plants Given Miracle Grow Have Brown Spots On Leaves

Question From: Leesburg, Florida, United States
Q: my trumpet is doing the same thing could I be giving it too much Miracle-Gro all of my plans hibiscus and I don't even know what the other ones are has the same problem

A: If you are spraying it on the leaves when the sun in shining this high salt index fertilizer may be burning the tender greens. Best to drench the soil using a watering can and do so at sun down or early in the morning. Best And Happy Yardening, Nancy
