Commercial Floriculture

Air relations

• Industrial regions offer hazards to orchid growing, both by the production of smoke and haze which reduce the light available to the plants, and by the production of noxious fumes.
• When soot and grime collect on the plants, wash them off with a forceful spray of water at frequent intervals.
• Dirt collecting on the leaves may plug up the stomata and cut down the working power of the leaves.
