Q.how to transplant outdoor dracaena plant
How do I transplant an outdoor Janet Craig dracaena?
Transplanting any plant is basically always the same: select the proper site in terms of light, amend soil if necessary, dig up plant transporting as much soil as possible, and water well for the first couple of months (adjusting water according to plant, soil, and climate.) Janet craigs are going to do well in shade or light shade. You probably don't want to put them where sun will hit them directly.
