Summer gardening can be quite the task, with plants depending heavily on a good watering schedule to thrive through the heat.

It's not just about how much water they get; timing is crucial for keeping your plants happy and healthy.

Whether you're tending to your flower beds or nurturing your veggie patch, getting the watering time right is key to ensuring your greenery doesn't just survive but thrives.

Hozelock's Sarah Dixon points out that during those scorching summer days, plants can be left "struggling to survive".

But, she suggests that by watering at the "right time of day", gardeners can help their plants "survive a heatwave and continue to flourish", reports the Express.

So when should you be reaching for that watering can?

Miracle-Gro's gardening expert Kate Turner advises: "I always recommend watering in the evening when asked when is the best time to water plants."

She explains that watering in the cooler evening means "The water has more of a chance to work its magic, without being evaporated by the heat of the day. This ensures the water gets down to the roots, helping the plant stay hydrated."

Echoing this sentiment, David Andersen from David Andersen Garden Design says: "Particularly in the summer, the best time to water plants and vegetable patches is in the evening."

He notes that the lower temperatures allow the water to penetrate the soil and maintain moisture for longer periods.

Sarah Dixon adds her voice to the chorus, recommending: "I recommend watering your garden at the end of the day when the sun isn't so hot."

"This will prevent water from being wasted through evaporation, which can leave your plants dehydrated."

When watering plants, it's crucial to reach the roots with a thorough soaking.

By bringing the hose or watering can right up to the plant's base and directing the flow towards the soil, you minimise leaf wetness and maximise moisture where it counts.

Ensure you give each section a good drenching before moving on, then circle back for a second round. The initial watering softens the soil, allowing the follow-up to really sink in and reach the roots.
