Does bad soil cause leaf curl?

Yes, bad soil can contribute to leaf curl in plants. Poor soil quality, including nutrient deficiencies, poor drainage, or compaction, can stress plants, leading to symptoms like leaf curl. Additionally, imbalances in pH or soil microorganisms can affect plant health, exacerbating the problem. However, other factors such as pests, diseases, and environmental conditions can also cause leaf curl, so it's essential to consider all potential causes.
