Q.Hydrangea 9-1-1!!!

Zone 78801 | jodistrickland19 added on September 29, 2018 | Answered

My hydrangeas look awful! Is this an insect or a fungus issue? We’ve recently received about 12-15 inches of rain in the last 3 weeks. Could that be the issue? I recently purchased chelated iron, but I’m nervous to apply it.

This is, most certainly, a soil born infection. This can be due to heavy rains, and excessive moisture, along with the fact that hurricanes are notorious for bringing in new pathogens that plants in a specific area are not acustomed to.

I would recommend dolomitic lime and wettable sulfur. Applying these together will help kill off anything infecting the soil, as well as condition the soil back to a more suitable pH. It also contributes nutrients such as sulfur, calcium, magnesium, carbonates and improves soil quality.
