Q. Would a fig tree
produce figs if it got sun in the spring, fall and summer months but not the
winter? I have lots of spots to plant trees but a house blocks winter sun.

| The amount of light and the quality of light is important in flower and fruit production as well as increasing the branching of some plants. All plants have a minimum amount of light required to flower and maintain fruit production. The amount needed varies among plants but generally most of flowering and fruiting plants need at least 6 hours of direct sunlight every day |
A. Success depends on how
much sunlight plants get when leaves are out. When leaves are gone, sunlight is
not nearly as important. Winter sunlight is not terribly important for trees in
our climate because it is cold and the plant is dormant or “resting”. But light during spring and summer months, when leaves are out, is
very important. That is when sunlight is critical.

Fruit production is usually not controlled by an “on
and off” switch. As the total amount of light decreases, the amount of
fruit produced also decreases. At some point, if the plant does not receive enough light, flowering and fruiting stops. The amount of sunlight needed for flowering and fruiting varies somewhat among plants but fruit trees generally need a minimum of 6 hours of direct sunlight. If sunlight continues to decline during months
when leaves are out, at some point, there won’t be enough light for the plant
to make flowers and produce fruit. It stops producing fruit, only leaves and
stems.

| Foliage plant, and interior plant that produces only leaves and stems, growing under very low light conditions in the Amsterdam airport men’s bathroom. This plant was selected because it requires a very low light levels to produce leaves and stems and can take a very tough conditions. |
If a fig tree is getting a minimum of 6 hours of sunlight
when leaves are present, it will probably produce decent fruit. Not all this
light has to be direct sunlight. Reflected light also counts but not as much.In direct light, light from bright reflecting surfaces, will contribute to flowering and fruit production but more indirect light is needed than direct light. Much of this depends on the total amount of light as measured in footcandles per hour or watts per square meter per hour. The quality of light, the color, is also important because it can trigger some types of behavior in plants.

Fruit production also
depends on the “quality” of reflected light. If light is reflected off shiny or
white surfaces, then plants receive more light than light reflected from darker
or variously colored surfaces.
