DISA'NDRA PROSTRA'TA. See SIBTHORPIA PERE- 



GRINA. 



DISBUDDING is the removal, soon after they have 

 burst into leaves, of such buds as, if allowed to grow 

 into shoots, would be misplaced or superfluous. Thus, 

 buds protruded directly in the front of branches trained 

 against walls, or fore-right shoots, as they are correctly 

 termed, and buds that would produce shoots in places 

 already sufficiently filled with branches, may be removed, 

 or disbudded. The object is to strengthen the desirably 

 placed buds by thus confining to them the expenditure 

 of sap. There is no better mode of aiding a weakly 

 plant to a more vigorous and robust growth than judicious 

 disbudding ; but an ever-robust and super-luxuriant 

 tree had better be allowed to exhaust itself by a more 

 profuse development of leaf-buds. By judicious dis- 

 budding, which should always be performed gradually, 

 any whiter pruning is almost rendered unnecessary, and 

 in all instances is diminished.

 fleshy disk. Nat. ord. Rhamnads [Rhamnacea;]. Linn.
