Pine needle

Definition and stakes

Portrait of Albert Charles Seward Albert Charles Seward,  1911 Encyclopædia Britannica (1911)

“ A pine needle grown in continuous light differs from one grown under ordinary conditions in the absence of hypodermal fibres, in the absence of the characteristic infoldings of the mesophyll cell-walls, in the smaller size of the resin-canals, &c. The endodermis in Pinus, Picea and many other genera is usually a well-defined layer of cells enclosing the vascular bundles, and separated from them by a tissue consisting in part of ordinary parenchyma and to some extent of isodiametric tracheids ”

“ Pine needles are used for a mulch mainly because they were handy at first, clean of weeds and easy to apply, but the pine needle is getting more and more obsolete, like the tallow candle, and unless the grower changes his method of mulching or else uses a motor truck and goes a long distance he is out of luck in the future. ”
