Previous research I was involved in showed that aerosol sprays don’t linger, as James Wong found with water sprayed on plants. I don’t spray my water-loving plants and haven’t done for years. A stack of Maranta, moth orchids, Nepenthes and Venus flytraps are kept damp with regular light watering at a north facing window and thrive. Slow diffusion of water from a sufficient area of compost and the neighbouring pots is enough to stop even the dangling pitchers from drying out (4 November, p 44).
