On the other hand, clay soils are composed of very fine particles,poorly aerated, and are retentive of moisture and tend to be acid inreaction. Therefore, plants adapted to clay soils are generally mois-ture loving, free from large fibrous root systems, and are not nearly solikely to be hardy, especially if removed to another soil type. Light soils are said to be warmer than heavy ones. What is reallymeant by that is that the period of growth from spring to autumn islonger on a light soil than on a heavy one. For this reason, plantswhich start growth early in the spring, like peaches, or bloom late inthe autumn, like chrysanthemums, generally succeed better on a lightsoil. For the present, and until the underlying reasons are betterunderstood, experience will prove the best guide in selecting plantsfor the different soil types. |
