If planted in reasonably good garden soil then that's it for your skim, it will be more than happy to look after itself without any pruning, feeding or other care - truly a delightful shrub for the lazy gardener! They will last for around 20 years. -They have a definite preference for slightly acidic soil although they can grow well in neutral soil with a little help. They do not grow well in alkaline soils. They need semi-shade throughout the year

Mine grow extremely well in very alkaline, dry, sandy soil - I don't think this shrub is particular about growing conditions. I've never grown it in a tub, though.

They might need feeding in pots - assuming you topdress the pots in spring (scraping out loose soil and weed/lichen/algae/moss, then topping off with fresh compost) add a handful of Growmore granules beneath the fresh compost. alternatively, a couple of doses of Miracle Gro General Purpose in April and again in May. Do not feed now, though, its too late in the year.
