6. _Theophrastus_ in his Third Book _de Causis_, c. 7. gives us great caution in planting, to preserve the roots, and especially the earth adhering to the smallest fibrills, which should by no means be shaken off, as most of our gardeners do to trim and quicken them, as they pretend, which is to cut them shorter; though I forbid not a very small toping of the stragling threds, which may else hinder the spreading of the rest, &c. Not at all considering, that those tender hairs are the very mouths, and vehicles which suck in the nutriment, and transfuse it into all the parts of the tree, and that these once perishing, the thicker and larger roots, hard, and less spungy, signifie little but to establish the stem; as I have frequently experimented in orange-trees, whose fibers are so very obnoxious to rot, if they take in the least excess of wet: And therefore _Cato_ advises us to take care that we bind the mould about them, or transfer the roots in baskets, to preserve it from forsaking them; as now our nursery-men frequently do; by which they of late are able to furnish our grounds, avenues and gardens in a moment with trees and other plants, which would else require many years to appear in such perfection: For this earth being already applied, and fitted to the overtures and mouths of the fibers, it will require some time to bring them in appetite again to a new mould, by which to repair their loss, furnish their stock, and proceed in their wonted œconomy without manifest danger and interruption: nor less ought our care to be in the making, and dressing of the pits and fosses, into which we design our transplantation, which should be prepar’d and left some time open to macerating rains, frosts and sun, that may resolve the compacted salt, (as some will have it) render the earth friable, mix and qualifie it for aliment, and to be more easily drawn in, and digested by the roots and analogous stomach of the trees: This, to some degree may be artificially done, by burning of straw in the newly opened pits, and drenching the mould with water; especially in over-dry seasons, and by meliorating barren-ground with sweet and comminuted lœtations: Let therefore this be received as a maxim, never to plant a fruit or forest-tree where there has lately been an old decay’d one taken up; till the pit be well ventilated, and furnish’d with fresh mould.
