‘Best time of day’ to water plants ‘when it’s hot’ – ‘allows water to penetrate the soil’

Rachel pointed out that container plants will require watering “daily”, possibly even “twice daily” during a heatwave.

But take the cue from the plant itself and see if it’s wilting and looking thirsty.

The expert added: “Just as you don’t want it parched, you also don’t want to go to the other extreme and overwater it.”

Plants need to be watered generously, so that the water penetrates the roots.

However, The Greenhouse People also urge some caution around overwatering plants, “which can cause them to leach nutrients and cut off the supply of oxygen to the roots.”

They continued: “Instead, pick up the watering can and provide focussed watering at the base of the plant, so roots can benefit as quickly as possible.”
