Apple stocks are either grafted or buclded. Root-grafting is
the most common at the West. ; long cions are sometimes used
in order to securt’ own-rooted trees, although only a few varieties
root well On their own wood. Budding is performed in August
ad early St~pttwlwr in the northern states, or it may be begun
on strong stocks in J’uly by using buds that have been kept on ice.
Stocks shoul~l 1x1 strong enough to be budded the same year they
are transplanted, but. the operation is sometimes deferred until
tlie s~~con(l s~ininit~r. Stocks that cannot be worked until the

illustri~tions of tllrl rnethorls of grafting apple trees, consult many

For root-graftin,, [r strong one-year-old roots are best, but twoyear-oltls
art> often ristid. For piece-root work, the root is cut into
two or t hrcc pieces of 2 to 3 inches each. The lowest piece is
us~lally small and \veak, and is generally discarded. Whole-root

Apricot (1’tw~~ us urum imw, I’. claspxrp, P. df umc). Rosnceae.
The apricot t,hrivcs on a variety of stocks. Apricot stocks are
usc~i in apricot-gro\?-ing regions, especially for deep and rich welldrained
soils. The pits grow readily if given the same treatment
as that detailed for the peach (which see). The stocks are also
hanclleti in the s:lme way as peach stocks. Apricots on apricot
roots are riot liLr@Tl~ grown outside of California, in this country.
Apricot stocks can be grown from root-cuttings the same as cherries
and other stone-fruits, but this is lit.tlc practiced.
The apricot tloes well on the peach, especially on light soils.
In the warmer parts of the country peach is much used.
Plum stocks arc’ commonly used at the North, especially if the
trees are to be planted in moist or heavy soils. The common
plum is generally used, but. some of the native plum stocks
are coming into favor, especially in trying climates. The Russian
