Another option is selecting a plant that grows easily in heavy clay soil. Soil fertility and pH also affect plant selection and growth rate. Some plants require a regular application of fertilizer, while others survive quite well under low fertility. Likewise, particular trees and shrubs grow better in certain pH ranges. Too much or too little moisture may be a limiting factor when choosing a plant.
Few plants can tolerate constantly wet soil.
When soil is saturated with water, air is forced out. Plants cannot move oxygen from the leaves to the roots. Oxygen must be absorbed through the roots. However, some plants are adapted to wetter soil conditions. Conversely, there are few plants that thrive in excessively dry conditions.
