Hares And Rabbits

Hares And Rabbits are deterred from injuring trees and shrubs by mixing night-soil and clay in water, and daubing it over the stems with a brush, in November; and if the winter proves very wet, in February. The November dressing is, however, generally sufficient. This mixture has stopped their depredations entirely, even when they had commenced operations. - Gard. Chron.

Heading

Heading, or as it is also termed Cabbaging or Loaving, is an inaptitude to unfold the central leaves, characterizing the various members of the Cabbage tribe. They have their centre or bud composed of a larger number of leaves than usual, and these, in some instances, are so complexly combined that the plant has not sufficient power to force them open to permit the protrusion of the seed-stem. The closeness of the heading is regulated by the exposure to the light. In a shady situation all the leaves are required to elaborate the sap, on account of the deficient light rendering each less active; therefore they open as they are formed. In a free exposure a few leaves are able to effect the requisite decomposition; and hence the reason why cabbages always have "harder hearts" in summer than in spring or autumn, when the light is less intense.

Heading-Down

Heading-Down is cutting off entirely or to a considerable extent, the branches of a tree or shrub - a process not rashly to be resorted to, and adapted only to reduce them when the plant seems declining in vigour, or has attained an undesirable size.
