mpanion cropping.
"In companion cropping there is a main crop and a secondary crop.
Ordinarily the main crop occupies the middle part and later part of
the season. The secondary crop matures early in the season, leaving
the ground free for the main crop. In some cases the same species is
used for both crops, as when late celery is planted between the rows
of early celery.
Following are examples of some companion crops:
Radishes with beets or carrots. The radishes can be sold before the
beets need the room.
Corn with squashes, citron, pumpkin, or beans in hills.
Early onions and cauliflower or cabbage.
Horseradish and early cabbage.
Lettuce with early cabbage."
("Principles of Vegetable Gardening," page 184.)
If fruit trees be planted, vegetables may be grown in rows. As soon
as the early vegetables mature they are removed, and a midsummer
crop planted. These are followed by a fall or winter crop.
Radishes, lettuce, and cabbage grow at the same time and on the area
formerly used for one crop. Early potatoes and early cauliflower are
followed by Brussels sprouts and celery, two crops being as easily
grown as one by intelligent handling. The best beans are grown among
fruit trees.
The principles of "double-cropping" are summarized by Professor
Thomas Shaw, in _The Market Garden._
"Onion sets may be planted early in the season and onion seeds may
then be sown. Between the rows cauliflower may be planted. Later
between the cauliflower, two or three cucumber seeds may be dropped.
The onion sets up around the cauliflower may be taken out first, and
the cauliflowers in turn may be removed in time to let the cucumbers
develop.
"Midway between the rows of onions grown from seeds, we can plant
radishes, lettuce, peppergrass, spinach, or some other early relish,
which will have ample time to grow and to be consumed before harm
can come to the onions from the shade of any one of these crops.
When the onions are well grown, turnips can be sown midway between
their rows."
So we get two crops of onions, besides cauliflowers, cucumbers, and
turnips off the same place. Weeds won't have much chance in soil
treated like that.
"Multum in Parvo Gardening" (Samuel Wood) claims L 620 ($3100)
from one acre by the expenditure of considerable capital in growing
fruit against brick walls--it cost over $3100 to prepare the land,
of which the walls cost $2300. In this system the fruit trees are
