In a video for BritBox, the gardening expert shared how to tell if a houseplant is suffering from being overwatered and how to fix it. Monty explained: “The problem is in my hand because if I take it [plant] out of this rather attractive grey pot, it’s in a standard plastic pot. It’s a lysis of feather but I look at the pot it is in, there are no drainage holes of any kind.
“What’s been happening I suspect is it’s been watered and the water has said inside what is effectively a jar and it’s got too wet.”
Overwatering houseplants is one of the most common ways they suffer, and it can lead to root rot.
The expert said the “classic symptoms” of an overwatered plant include drooping and brown leaves.
Monty added: “A lot of houseplants, particularly foliage ones, like dark, cool and damp conditions.
He added: “You’re looking at keeping it pretty dry but misting it daily.”
In the spring and summer months, when plants are no longer in dormancy, Monty recommended keeping on top of feeding them.
The expert said this encourages “lush growth and lots of greenery”.
Houseplants such as the Swiss cheese plant, prayer plant and a peace lily can all benefit from regular feeding in the warmer months.
Succulents and cacti don’t need food to survive, even in the summer.
