Tips For Irrigating Grapes – How Much Water Do Grapes Need

Growing grapevines at home can be an exciting endeavor for many gardeners.
From planting to harvest, the process of promoting healthy growth can be quite
elaborate. To produce the best crop possible, those wishing to grow grapes will
need to carefully consider garden routines such as pruning
and fertilization. Irrigation procedures are also a vital aspect. Learning
more about properly irrigating grapes can promote more productive harvests each
season.

How Much Water Do Grapes Need?

As with any other planting, watering grapes and maintaining
adequate moisture levels will directly impact plant health. Grapevine
irrigation can vary depending upon the conditions in each growing zone.
However, there are some key aspects on which to focus.

When choosing how and when to water grapevines, it will be important to maintain balance. Ideally, the soil should remain adequately moist throughout the entire growing season. This means that water should be available to the plants’ roots at any time.

Drought stress can manifest in grapevines in a wide variety of ways. First, growers may observe the wilting of leaves or tendrils of the plant. If the need for water is too severe, the vines’ flowers may also drop and result in the uneven formation of clusters. Signs of too little water may also include the yellowing of leaves, as well as fruit drop.

Professional grape growers often use periods of water stress
to encourage or produce the desired qualities in the mature fruit. However,
these techniques will require great familiarity with the cultivar being grown
and with the growth timing of each grape plant. For this reason, it is best
that most home growers do not attempt these water stress techniques.

Though the grapevines will require consistent moisture, it
is important to note that this does not mean that the soil should be
excessively wet. Excessively wet soils that are the result of over-irrigation
or poor drainage will promote the decline of the plant. These soil conditions
can promote root rot of the plants, increase the likelihood of disease in the
vines, and cause the loss of soil nutrients.

In irrigating grapes, make certain to avoid overhead
spraying. Watering in this manner can promote the development of fungal and bacterial
diseases. For many, drip irrigation hoses, which deliver water directly to the root zone, are the
best option. Though the need for irrigation will vary depending upon rainfall,
most plantings will require about 1 inch (2.5 cm.) of water each week of the
growing season.
