The downside of nighttime watering? Damp leaves and soil can provide the conditions for mildew.
Benjamin Pope, author of What to Grow, Sow and Do said: “The wet conditions can also encourage slugs and snails to be active, hence late afternoon and early evening waterings should have some time to dry before the nocturnal pests arrive.
“It’s worth remembering, if temperatures are due to lower significantly to freezing, then this should be avoided and watering early in the day is better.”
Gardeners have also been urged to avoid watering their plants during the day.
