Struggling to keep your house plants looking green and healthy? Your choice of plant pot could be to blame, according to this Monty Don house plant watering tip.
Speaking in a video for BritBox, the Gardeners’ World presenter explained that if the leaves of your house plant are starting to brown, and the stem has started to shrivel, these are symptoms of overwatering. Even if you are giving your house plants the correct amount of water you can still overwater them if they are in the wrong plant pot.

‘If I look at the pot, it's got no drainage holes of any kind and what's been happening, I suspect, is they watered it and the water has sat inside what is effectively a jar,’ he explained holding up a shriveled house plant.
‘It's got too wet and it's showing classic symptoms of an overwatered plant which are drooping leaves that are turning brown. So never keep any house plant in an undrained container unless you let it drain completely.’
Decorative plant pots are a key part of styling a collection of house plants at home. However, many of them don’t include drainage holes. Leave your house plants in a container with plenty of drainage holes before putting them inside a decorative plant pot.
When watering, if your plants are small enough, take them out of their decorative pots and water them in the sink so that they are able to drain properly.
Monty Don pointed out that another cause for your house plants turning brown could be the conditions in your house.
‘A lot of house plants, particularly foliage ones like the aspidistra, like dark cool damp conditions,’ he says. 'Most houses are too hot and too dry so a mister is an essential piece of kit to combat this.
‘If you mist the leaves of house plants, for an awful lot of them, that will make them happier than anything else,’ he adds.
Houseplants are a wonderful addition to your home for aesthetic reasons, but can also have an amazing impact on our wellbeing. Look after them carefully and reap the benefits.
How often do you water a house plant?
How often you water a house plant does vary from plant to plant, on their size, the pot they are in, the temperature of the room, their position in the room and their growth rate.
However, most of us are guilty of over-watering them. Most houseplants only need to be watered every week to three weeks – but the best approach is always to only water a house plant when it needs it, not just because you are in the habit of watering house plants on a Saturday, for example.
How do you know if a plant needs water?
Avoid watering to schedule and instead check if your house plant really needs watering to avoid over-watering. The easiest way to do so is to insert your finger into the soil and if the top inch or so feels dry, you can water it. If however, the soil feels damp, leave the watering for another couple of days.
What is the best way to water house plants?
The answer to this is: all around the roots. If you water just one side of the plant (presumably because it's easiest for you to reach), the water will filter down to one side of the house plants roots, and the plant will grow towards the watering direction. So, for a plant that's well-formed all round, turn the pot as you water it to ensure the water is delivered evenly over the roots.
As for how much water to give a house plant, the best measure is to water until it drips out of the bottom of the plant pot. Then you know that you can stop.
