{SN: Trees against a wall.} This prouoketh most of our great Arborists, to plant Apricockes, Cherries and Peaches, by a wall, and with tackes, and other meanes to spread them vpon, and fasten them to a wall, to haue the benefit of the immoderate reflexe of the Sunne, which is commendable, for the hauing of faire, good & soone ripe fruit. But let them know it is more hurtfull to their trees then the benefit they reape therby: as not suffering a tree to liue the tenth part of his age. It helpes Gardners to worke, for first the wall hinders the roots, because into a dry and hard wall of earth or stone a tree will not, nor cannot put any root to profit, but especially it stops the passage of sap, whereby the barke is wounded, & the wood, & diseases grow, so that the tree becomes short of life. For as in the body of a man, the leaning or lying on some member, wherby the course of bloud is stopt, makes that member as it were dead for the time, till the bloud returne to his course, and I thinke, if that stopping should continue any time, the member would perish for want of bloud (for the life is in the bloud) and so endanger the body: so the sap is the life of the tree, as the bloud is to mans body: neither doth the tree in winter (as is supposed) want his sap, no more then mans body his bloud, which in winter, and time of sleep draws inward. So that the dead time of winter, to a tree, is but a night of rest: for the tree at all times, euen in winter is nourished with sap, & groweth as well as mans body. The chilling cold may well some little time stay, or hinder the proud course of the sap, but so little & so short a time, that in calme & mild season, euen in the depth of winter, if you marke it, you may easily perceiue, the sap to put out, and your trees to increase their buds, which were formed in the summer before, & may easily be discerned: for leaues fall not off, til they be thrust off, with the knots or buds, wherupon it comes to passe that trees cannot beare fruit plentifully two yeares together, and make themselues ready to blossome against the seasonablenesse of the next Spring.
