Your plants are packaged in a thick cardboard shipping carton that is especially designed for live plants. Although we don't have a minimum quantity that you can order, the shipping carton is designed to carry 4 plants. The postage price for this carton is the same whether you get 1 or 4 plants, so to maximise the space we suggest buying in multiples of 4. For example, 4 plants = 1 carton, 5 plants = 2 cartons, 8 plants = 2 cartons.
You can then use the packaging around the plant under your mulch OR recycle the packaging in a responsible way.
