For African violets, 'hands off' means healthier
Date:11/3/2009

onds with a latex-gloved hand, brushed for 90 seconds with a latex-gloved hand, brushed for 30 seconds after applying lotion to a nongloved hand, and brushed for 90 seconds with lotion on the nongloved hand.

After five weeks the plants were harvested. At harvest, plants were rated on a scale of 1 to 5 (no damage dead/near dead). Plants that were brushed by a gloved hand had lower damage ratings, greater leaf areas, and greater leaf numbers than plants that were brushed with a nongloved hand to which lotion had been applied. The cultivars varied in their response, with 'Michigan' exhibiting more damage from brushing than 'Gisela'

Summarizing the results, Cole remarked that "the study suggests that repeated brushing reduces plant size and quality of african violets, particularly when done with a bare hand to which lotion has been applied. Brushing leaves of african violets is not recommended because repeated brushing can decrease plant quality and size."

The next time you are tempted to touch that pretty african violet in your kitchen window, remember for a healthier plant, keep your hands off!
