Varieties of olives differ greatly in the readiness
with which they start from small cuttings. Some start freely and grow
well in boxes of sand under partial shade - like a lath house or cover.
Some need bottom heat in such a hotbed as you describe with a cloth
over; some start well in a cold-frame with a lath cover. To get the best
results with all kinds, it is safer to use some more heat than comes
from exposure to ordinary temperatures - either by concentration, as in
a covered frame, or by a mild bottom heat. If you have glass frames or
greenhouse, they are, of course, desirable, but much can be done without
that expense.
Olives from Large Cuttings.
I am about to take olive cuttings from one-half to one inch thick and 54
to 20 inches long, and wish to root them in nursery rows. Please advise
me if it is necessary to plant under half shade? Also, can same be
planted out right away, or should they be buried in trenches for a while
before setting out? Would it be best to strip all leaves or branches
off, or leave one on? How many buds should be left above ground?
Plant in open ground in the coast district generally; in the interior a
lath (or litter shade not too dense) is desirable in places where high
dry heat is expected and where sprinkling under the cover may be
desirable. Plant out when the soil is right as to warmth and moisture,
which is usually a little later than this in the central and northern
parts of the State.
