PBH rice hulls on top for weed control

Herbicides and hand weeding have long been the two options for managing weeds in nursery containers. In recent years, however, a new grower-developed technique has emerged and gained significant credibility. Nursery professionals have discovered the benefits of managing weeds by topdressing containers with parboiled rice hulls – a weed management practice now substantiated by USDA research. Although rice hull topdressing may not totally eliminate the need for herbicides and/or hand weeding, it can reduce both and provides several other key advantages.

A rice hull topdress of 1 to 2 inches offers the following:

• Prevents airborne weed seeds from reaching the growing media and germinating
• Dramatically decreases container weeds, including moss species such as liverwort
• Significantly reduces hand-weeding labor and expense
• Provides excellent potential for reduced herbicide use
• Helps decrease damage in herbicide-sensitive plant material
• Can reduce drought stress and watering
• Costs just pennies per container
• Provides economical, earth-friendly weed management
