Answer: Without knowing what kind of plants these are it is a bit difficult to make specific suggestions. However, stunting can occur for a variety of reasons. For example, planting heat loving plants like tomatoes into cold soil may stunt them. Planting rootbound plants without untangling or cutting the roots can cause the roots to be stunted and reduce top growth. Planting into unimproved clay soil can cause the roots to stay constricted and stunt the plants as a result. Sometimes there is a soil condition that prevents growth such as soil pH that is excessively acidic or alkaline, or soil that has been overfertilized can "burn" the roots, or soil that is poorly drained can damage the roots by sitting in excess moisture. There might have been an accidental chemical spill or drift of herbicide, or there might be an allelopathy problem with a nearby black walnut tree. I hope this gives you some ideas as to the kinds of reasons plants may fail to grow. Your local county extension might also be able to help you trouble shoot based on their knowledge of the local growing conditions.
