Yes, you can put in leafs and pieces of fruit, grass, lettuce,...etc to moisten up the bud, but I warn you to keep an eye on how long you keep it in the container your storing it in. If you don't mold can and will happen. Check at least 2 to 3 times a day and just set it in the container with the bud, not on top of it or touching it. And it doesn't take a lot of material to moisten it up a little goes a long way. Smell and overall smoke are definitely affected by this technique however, and is done only as a last resort.
