Weed Control

Hybrid poplars need good weed control for the first three to four years. Once the hybrid poplar canopy is well developed, its shade is very effective in eliminating further weed competition until harvest.

Weed and grass control may be accomplished by the use of labeled herbicides and by cultivation. Common farm equipment can be used to perform both chemical and mechanical weed control operations. A person familiar with the application of herbicides in short rotation forestry should be consulted on the use of specific herbicides and cultivation practices to ensure good results.

• The most successful weed control is a result of good site preparation.
• If a pre-emergent herbicide is used, get instructions from a person familiar with herbicide use on young trees.
• Cultivation will be necessary, but must be shallow, and done with care to avoid root pruning.
