Renewing





Because of the comparatively short life of several of the

most useful of the varieties of clover, no attempt is usually made to

renew them when they fail, unless when growing in pasture somewhat

permanent in character. To this, however, there may be some exceptions.

On certain porous soils it has been found possible to maintain medium

red clover and also the mammoth and alsike varieties for several years

by simply allowing some of the seed to ripen in the autumn, and in this

way to re-seed the land, a result made possible through moderate grazing

of the meadow in the autumn, and in some instances through the absence

of grazing altogether, as when the conditions may not be specially

favorable to the growth of clover.



It is not uncommon, however, to renew alfalfa, by adding more seed when

it is disked in the spring, as it sometimes is to aid in removing weeds

from the land. The results vary much with the favorableness of the

conditions for growing alfalfa or the opposite.



In pastures more or less permanent in character, clovers may be renewed

by disking the ground, adding more clover seed, and then smoothing the

surface by running over it the harrow, and in some instances also the

roller. This work is best done when the frost has just left the ground

for a short distance below the surface.



Some kinds of clover are so persistent in their habit of growth that

when once in the soil they remain, and therefore do not usually require

renewal. These include the small white, the yellow, the Japan, burr

clover and sweet clover. In soils congenial to these respective

varieties, the seeds usually remain in the soil in sufficient quantities

to restock the land with plants when it is again laid down to grass.

Nearly all of these varieties are persistent seed producers; hence, even

though grazed, enough seed is formed to produce another crop of plants.
