Diseases incident to Fruit-Trees.
FRuit-trees are subject to divers Diseases. Baptist. Port. saies,* 1.1 Affliguntur Plantae omnes, veluti Animalia, diversis morbis. All Trees or Plants are afflicted with divers Diseases as sensible crea∣tures. And therefore we should apply our selves to Cure them, not for pitty to the Trees (as the indulgent compassionate Ma∣nichees) but for our own profit.
I shall (at present) mention only three Diseases that sometimes happen to Fruit-trees. Mossinesse, Bark-bound, and Canker.
Concerning Mossinesse of Fruit-trees, the way to cure that (and other Diseases) is to take away the Cause, sublatâ causâ,* 1.2 tol∣litur effectus. If the spring be stopt, the streames cannot runne. Some to cure this, only scrape off the Mosse, not indeavouring to take away the Cause, so that in a few yeares they are as bad a∣gaine, that's but like endeavours for cure of the Tooth-ach, or Gout, or the like, with some outward applications (which though they may give some ease for a while, yet they strike not at the root, they remove not the Cause, and therefore they returne a∣gaine. So that it must be considered what the Cause of Mossinesse is, sometimes it is caused by over coldnesse of the ground, as in wa∣terish, and clay grounds, likewise by Barrennesse of the soyle.
If it be Coldnesse through moysture, then use all means to lay it dryer, by trenching the ground: or if it be Clay-ground, then bring in some warmer soyls to mixe with it, as Sand, Ashes, Sheeps-dung, Pigeons, or Hens-dung, or the like: If the soyle be too bar∣ren, then help it by mixtures of good soyles, round about the Roots.
But withall take away the Mosse that is already upon the trees, in this manner; after Raine rub it off with a Haire-cloth: else scrape it off with a piece of hard wood in the forme of a knife.
Another is the Barke-bound disease:* 1.3 This exceedingly hinders the growth of trees: it makes them live lingringly and poorly: This happens when there is but a dull, and slow passage up of sap, and in small quantity, either by reason of barrennesse of soile or want of due culture, to the Branches, therefore if the soile be barren it must be mended, and likewise some of the Bran∣ches cut off, and the rest scored downe all along
