How to grow Coleus

These chaps are rather partial to a warm spot, about 18-24°C, just like a pleasant British summer’s day. Give the tips a gentle pinch now and then, encouraging them to bush out like a well-pruned hedge. To give your Coleus a proper British upbringing, nestle them in well-drained soil and a spot with a bit of dappled shade – they don’t fancy too much sun, you see. Keep the soil as moist as a morning in Manchester, but no waterlogging, mind you. And don’t forget a spot of fertiliser every 4-6 weeks during their growing season, just like regular tea breaks. Follow these nifty little steps, and your Coleus will be the toast of the garden, or a dashing addition indoors, flaunting their colourful leaves with all the pomp and ceremony of a royal parade.
