Growing Vegetables in the Shade

Farmers often feel they need a lot of sunshine to produce a good
crop. The Rodale Institute in Pennsylvania, however, says lots of
vegetables grow well without much sun.

The research center published a report about this subject some
years ago in its magazine Organic Gardening. The report said many
different kinds of foods from blueberries to beans can be grown in
the shade.

Some vegetables do need a lot of sun. A vegetable crop expert at
the University of Maine advised putting these vegetables where they
can get from eight to ten hours of sunlight a day. Tomatoes, melons,
squash and peppers are among those that need the most sun.

Plants that produce root crops, such as carrots and beets, need
from six to eight hours of sunlight every day. But leafy vegetables,
such as lettuce and spinach, need only six hours of sunlight a day.

The Rodale Institute says a garden should be planned carefully
especially if you grow different kinds of foods. For example, rows
of vegetables should be planted in an east-west direction. That way,
as the sun passes overhead, all the plants will receive an equal
amount of light. This is especially important when the plants grow
to different heights.

Nut trees such as filbert, hazelnut and yellowhorn produce well
with only sun in the morning.

Some fruits also do well without a lot of sunlight. In the United
States, blueberries, raspberries, and several kinds of pears need
only a little sun each day. In Asia, the hardy kiwi grows well in
the shade.

Many herbs grow well without much sun. Mint plants, for example,
grow well in the shade. So do sage, dill, oregano, borage, chamomile
and several kinds of thyme.

The owner of a garden seed company warned against removing shade
trees. He cut down all his shade trees to provide more sun for his
crops. But then he had to protect his summer lettuce from the heat
of the sun by hanging a piece of cloth to provide shade.

Instead of cutting trees, he suggested putting plants that need a
lot of sunlight, such as tomatoes, in containers. That way they can
be moved as the sun moves.
