Smothering and decay of the roots fol- low. Seeds planted under such conditions usually fail. The soil water that is most useful to land plants is that which remains attached to the soil particles after percola- tion has nearly ceased (capillary water). Such water is well aerated because it is interspersed with cavities that are filled with air (91). In the open ground the remedy for excessive soil water may usually be found in underground drainage. But the same trouble often occurs in potted p...lants, as the result of too compact soil or too copious watering. The expert recognizes this condition by a sour odor of the soil, by lifting the pot, or by tapping the pot with his knuckle. If the soil is soggy, the weight will betray the fact, or the K 129 130 PRINCIPLES OF PLANT CULTURE sound given out by the pot will be that of a compact mass instead of a more or less hollow body, as is the case with a pot of well-aerated soil. To remedy the evil, repot the plant in fresh soil of a proper condition of mois- ture, providing abundant drainage at the bottom of the pot (412).
