Gifting a terrarium with live plants
As plants need water and light to thrive they'll need to be looked after. Once you receive your parcel, simply place the plants in indirect light and water them when the soil becomes dry. The plants can be wrapped before being gifted. As long as the plants are properly cared for, the terrarium can be made at any convenient time.
