On his blog, he explains that people often go wrong when watering their plants, leaving them without the right levels of moisture to grow healthily - but it's not as simple as just watering them frequently enough.

'By and large, the biggest mistake people make with their houseplants is to overwater them,' Monty begins. 'In fact,' he continues, 'that can be qualified - or refined - by saying most are overwatered at the roots but under-watered in the air.' He says that the single most useful thing is you can do is to get hold of a good mist sprayer 'holding at least a litre of water and with a trigger action.' 

'Use this twice a day,' he says, 'to give your plants a really good spray so the foliage is running with moisture.' As he points out, this will mean plants need to be positioned in a room where humid air isn't going to damage any soft furnishings. Therefore, he suggests putting houseplants in a bathroom or kitchen with natural light might be more practical than in the living room.

As for when to water plants, he reminds fans to only water when the compost is completely dry, and to soak them in a basin for 15 minutes, before draining them and returning the pot to its usual spot. If you fancy heading outdoors, our garden design ideas piece is full of inspiration.

The gardening guru comments that evergreen plants from tropical regions, such as a Bird of Paradise or Fiddle Leaf Fig, are happiest in a cool spot away from direct sunlight. They'll be better off here than a sun-flooded room right by a radiator, he explains.
