This is a philosophical poem which, not only is literal but also metaphorical. The first stanza ventures the fact that how beautiful things are often taken for granted. But beauty does not last forever. Even a flower has to wither someday. A person maybe beautiful but old age will take that away too. Just like flowers, people shouldn't play with the hearts of beautiful people and then leave them when they lose their beauty; that is not love, but lust. The second stanza focuses on the literal part of the poem. Children are often seen to tear flowers from trees without thinking, and that's perfectly fine. It is natural children's behavior, but there's always a lot to learn. Even though picking one or two flowers is completely okay, children should learn to not waste flowers by simply picking them for no reason and when they get tired of playing with them, tossing them away. They should be taught to be soft hearted and understand the value of the little things in life and how, flowers are more beautiful alive than dead; which is portrayed in the third stanza.
