Rool-prunins\smost. commonly practised in fruit-tree cultiva-tion. It is often resorted to as a means of restoring fertility inplants which have become over rank from an excess of nourishmentin the soil, or sterile from want of it. The effect of root-pruningin the first case is to reduce the supply of crude sap to thebranches, and consequently to cause a check in their develop-ment. In the second case all roots that have struck downwardsinto a cold uncongenial subsoil must be pruned off if they cannotbe turned in a lateral direction, and all the lateral ones thathave become coarse and fibrclcss must also be shortened back bymeans of a clean cut with a sharp knife, while a compost of richloamy soil with a little bone-meal, and leaf-mould or old manure,should be filled into the trenches from which the old sterilesoil has been taken. The operation is best performed early inautumn, and may be safely resorted to in the case of fruit trees.

In all these cases the cutshould be a clean sloping one, and made in an upward and out-ward direction. The root-pruning of pot-plants is necessary in the case of manysoft-wooded subjects which are grown on year after year—pelargoniums and fuchsias, for example. After the close pruningof the branches to which they are annually subjected, and whenthe young shoots have shot forth an inch or two in length, they areturned out of their pots and have the old soil shaken away fromtheir roots, the longest of which, to the extent of about half theexisting quantity, are then cut clean aw
