Why are my leaves turning yellow with spots?

Poor drainage or improper watering Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can’t breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.

Why do roses get yellow leaves?

Rose leaves turn yellow because the pH of the soil is too high, or there’s not enough iron in the soil.
