We keep our ghost and reaper plants growing year-round. We keep them in a glasshouse and give them a regular feed a top dressing of NPK fertiliser. And we also water when the plants start to look dry. If you wanted to over winter the plants at home and you don’t have a greenhouse you could move the plants inside (if they are in pots) put them in a conservatory or by a sunny window. If the upper branches are looking scrappy you can prune the bush back to healthy growth and the plants will take off from there. Make sure you feed the plants if they start to look yellow.
