We highly recommend that you open the box as soon as it arrives in the post. The time from dispatch from our warehouse, to arriving with yourself the plant has been starved of light. Plants need light to survive, so it's best to limit their time in the box which is only for transit purposes.
If you are gifting a 'Barry's Cactus' to someone else, but ordered to your address in advance of the date. You need to remove the plant from the box on arrival, as the plant needs sunlight daily to survive. Unfortunately by leaving the plant in the box, this will ultimately die.
This cacti has died, as it has been in the transit box for a long period of time
