Description is what makes the reader a sensory participant in the story. Good description is a learned skill,one of the prime reasons you cannot succeed unless you read a lot and write a lot. It's not just a question of how-to, you see; it's a question of how much to. Reading will help you answer how much, and only reams of writing will help you with the how. You can learn only by doing.
