Drain Your Soil
JN the case of tiny seedlings and juvenile plants, it must be borne in mind that root activity depends very largely on soil temperatures being equal to or higher than the temperature about the leaves and branches of the plants. If the soil is heavily charged with stagnant water, the temperature is bound to he considerably below that of the atmosphere, because, so long as all space between solid soil particles is occupied by water, air from above is prevented from percolating. Unless the requisite proportion of air enters the soil, conversion of crude •dements into available plant food cannot proceed. Neither can root extension and activity he maintained so long as the earth about existing roots is chilled by excessive moisture.
