"Keep your flowers away from ripening fruit or vegetables (especially bananas and apples)! They might seem odorless, but they give off in invisible gas called ethylene. It might be harmless for humans, but your flowers will suffer and not last as long as desired!"
"Remove fallen leaves from your lawn to prevent grass from dying due to lack of light! But remember to keep the leaves to use in plant beds and for potting soil, as they will convert into a rich and nutritious leaf mold for your plants!"
