I am worried that I may have not watered enough during our heatwave. I am still pretty new to gardening and it's hard to tell at times when I need to water. The temps were hot and the water would evaporate on the surface, but the soil underneath still seemed moist. I planted a rose of sharon during the summer and the leaves got scorched
:( I am so sad about this. I was afraid to overwater in fear of drowning it, so It's been crazy trying to figure this out.
But yes it's strange that the color of the leaf has turned brown and doesn't have brittle tips and edges. And there has not been any wilting. The leaves feel healthy to the touch. No I had not fertilized it until just a few days ago. I noticed that there is a slight reddish/purple color as well. Maybe this is a nutrient deficiency. It's hard to tell since I can't find anything that resembles the changes in my lilac. Thank you so much for your response
