Tea as Leaf Spray: No Benefit, Potential Risk

Owner sprays 100% natural tea on leaves, asks if good and how often.

Verdict

• Tea may clean or add slight shine.
• No humidity increase.
• Plants absorb nutrients through roots, not leaves.
• Mineral content unknown and unregulated.
• Possible leaf damage from unknown compounds.

Better Practice

Soap and water cleans leaves effectively. Proper soil provides all nutrients. Household remedies have "popular appeal, but no real benefit."
