Orchids

[piece of heaven]

I received two orchids. I don't know much about their care. Can someone help me? How should I water them? In how long? They have fertilized?
They're beautiful and I hope that they resist as long as possible.

I am very happy. My orchids have survived and they bloom. I saw the flower stem grows as buds develop as the flower unfolds. It is wonderful flower
