Green and shinny plants
The leaves in your plants will glow if you clean them with a cloth impregnated in beer or in vinegar and water.
Wet a cotton ball in egg white and clean the leaves of your plants with it.When the leaves of your plants start to lose their color, turn them to their natural tone with clean soap water.
Never use oil to give shine to the leaves of your plants because this will cover the pores and they will wither.
To have beautiful plants water them with a very light infusion of tea. The leftover tea grinds can be mixed with the soil.
