Bush fruits, such as currants and gooseberries, are frequently
propagated by stem cuttings, as in the case of roses. Another method,
which is known as layering, consists in bending one or more of the
lowest branches down against the ground, fastening it there by means of
a forked stick, and then covering it with two or three inches of earth.
The part in contact with the moist earth will send out roots, while one
or more shoots will come up. When roots and shoots have developed, the
branch is severed from the parent bush and the new plant set in its
permanent place. Strawberries exhibit a sort of natural layering.
PLANTING AND CARE OF HERBACEOUS PERENNIALS
Perennials grown from seed the previous summer should now be set in
clumps two or three feet apart in the perennial border or here and there
beside the fences or walks. The soil should be made fine and fertilized
with well-rotted manure from the compost heap before setting out the
young perennials. Dahlias and gladioli which were taken in in the autumn
should now be set out. The dahlias should be divided and only the best
roots used. Other perennials that have grown into large clumps should be
dug up, divided, and re-set in well-fertilized soil.
GARDEN STUDIES
Pupils in this Form have now had enough experience in the growing of
vegetables and flowers to allow them to make intelligent variety tests.
They should grow some of the less familiar varieties and report on the
merits of each variety tested. This, however, should not be carried on
to the exclusion of the well-known standard varieties. Let the pupils
consult the best seed catalogues available and choose for themselves
some varieties not already known to them. They should keep a systematic
record of all varieties grown and the methods used in cultivating,
fertilizing, etc. The knowledge thus gained will be of value in after
years, and the homes will also benefit by it.
BIENNIALS
The pupils should observe the second year's growth of biennials. A
special plot in the school garden should be set apart for this purpose.
Have them plant in it a turnip, a carrot, a beet, a cabbage, or any
other garden biennial saved over winter for the purpose. If desired, the
pupils might grow their own seed of these varieties. Notice (1) what
part of the plant has become enlarged with stored up food and how big it
is when planted, (2) how this part changes in size and texture as the
flowers and seeds develop, (3) in what way this extra food seems to have
been used.
WILD FLOWERS
STUDY OF THE TRILLIUM
The pupils bring the plants for the lesson. There should be a few purple
trilliums among the white, and some of the plants should have the
underground parts intact.
Discuss with the collectors their observations on where the trilliums
grow, the kind of soil, the depth of the root-stocks below the surface,
the uses of the root-stocks, insect visitors.
