How to Remove a Basal Grape Leaf

For those who grow grapes as either a hobby or in a vineyard, removing the basal leaves is a way to control pests that prefer those leaves, such as the variegated leafhopper. A basal leaf is one of the first few leaves on the stem of the vine. Many grape-growers remove all of the leaves, but this can be controversial because there is some evidence that doing so can affect the quality of the grapes. Basal grape leaves can be removed either by machine or by hand. For the home-grower, removing them by hand is simpler.

Instructions

- 1
  Plan your leaf removal to occur either before grapes set or after. Some grape-growers prefer to remove the leaves before the fruit sets, encouraging bud production and giving more sun immediately to the grapes. However, later removal means that the grapes will benefit from the protection of the leaves for longer, including protection from rot.
- 2
  Wait until vine growth slows in May or June for late leaf removal. Early removal can be done in March.
- 3
  Remove about half of the leaves on the side that receives less sun. The side receiving more sun is often called the "afternoon" side. New leaves that grow will generally grow pointing down, staying away from the grapes.

  Clip the leaves with your pruning shears at the point where the leaf stem meets the vine. Make a quick, clean cut to avoid tearing.
