Planters are united in the opinion that pruning, cutting, or in any way lacerating the roots is injurious to the cacao, and in deference to this opinion all cultivation close to the tree should be done with a harrow-tooth cultivator, or shallow scarifier. All intermediate cultivation should be deep and thorough, whenever the mechanical condition of the soil will permit it. A plant stunted in youth will never make a prolific tree; early and continuous growth can only be secured by deep and thorough cultivation.

Of even more consideration than an occasional root cutting is any injury, however small, to the tree stem, and on this account every precaution should be taken to protect the trees from accidental injury when plowing or cultivating. The whiffletree of the plow or cultivator used should be carefully fendered with rubber or a soft woolen packing that will effectually guard against the carelessness of workmen. Wounds in the bark or stem offer an inviting field for the entry of insects or the spores of fungi, and are, furthermore, apt to be overlooked until the injury becomes deep seated and sometimes beyond repair.

With the gradual extension of root development, cultivation will be reduced to a narrow strip between the rows once occupied by the plantain or the abacÁ, but, to the very last, the maintenance of the proper soil conditions should be observed by at least one good annual plowing and by as many superficial cultivations as the growth of the trees and the mechanical state of the land will admit.
