The method of choosing and rooting cuttings has been outlined in a
previous chapter (see page 29). In greenhouse work the main difference
is that they are taken in much larger quantities. For this reason it is
usually convenient to have a cutting
bench instead of the flats or
saucers used in rooting house plants. The bench should be three or four
inches deep, filled with medium coarse, gritty sand, or a substratum of
drainage material. If possible, have it so arranged that bottom heat may
be given--this being most conveniently furnished with pipes under the
bench boxed in. (The temperature required for most cuttings will be
fifty to fifty-five in the house with five to ten degrees more under
the bench.) The cutting bench should also be so situated that it readily
may be shaded, as one of the most important factors of success is to
prevent the cuttings from wilting at any time--especially just after
placing in the sand. After rooting, the cuttings are put into small pots
or flats as already explained.
Spring stock of some plants, such as geraniums, are rooted in the
fall--September to November. Others, which make a quick growth, such as
petunias, not until early in the spring,--last of January to April, but
for the most part in February. In the former case, cuttings are taken
just before frost from outside plants, or later from stock plants lifted
and taken indoors; in the latter case, stock plants are taken in and
carried through the winter in a more or less dormant or resting
condition; being kept rather dry and started into active growth in
January. The new growth furnishes material for cuttings, which are grown
on as rapidly as possible.
The following plants are treated in one of the above ways; further
details in any case may be found in the first part of the book:
Alternantheres Heliotrope
Begonias, fibrous rooted Ice Plant
Coleus Paris Daisy
Cuphia Petunias
Geraniums Salvias
Ivy Geraniums Vincas
German Ivy
