Plant Problems Caused by Weather and What People Do, April 22 — Solving plant problems becomes simpler when you know how to accurately identify the cause. This session aims to enhance your ability to do that.
Scientific research indicates that 70– 90% of garden problems are not caused by pests or diseases. They are caused by non-living factors, such as too much or too little water, extreme temperatures, mechanical damage, too much or too little light, a nutrient deficiency, or toxicity.
This session will cover problems caused by non-living factors, and will offer remedies to help fix the majority of plant problems.
