How to water plants and flowers on hot days

The UK is currently facing a prolonged period of dry weather, posing challenges for the healthy growth of garden flowers and plants.

Warmer weather means our plants and flowers need plenty of water to avoid drying out and continue thriving.

When the sun is out, it can be difficult to know how to water your plants and what time of day is best to do it.

To help your plants continue to thrive, Elise Harlock, Brand Manager at Prestige Flowers has shared some tips on how to water plants in hot weather.

Elise said: “The UK is currently facing a prolonged period of dry weather, posing challenges for the healthy growth of garden flowers and plants.

“On hot days, deeper, less frequent watering is preferred over quick sprinkles throughout the day. This encourages deeper root growth, building your plants’ resilience to heat and drought.”

What time of day is best to water plants?

Elise from Prestige Flowers explained: “You should water in the early morning, before temperatures rise or the sun’s heat is at its strongest, to give the moisture a chance to be absorbed by the soil.

“Midday watering in this heat would be pointless, as the water will evaporate before reaching your plants’ roots.

But be aware, damp plants overnight can attract pests who might seek shelter and moisture.”

She added: “When watering during a heatwave, you need to make sure you make every drop counts. After very little rain in parts of the UK recently, reservoirs and groundwater levels will be depleted.

“Always aim for the roots, not the leaves, to ensure the water gets where it’s needed. Be gentle and use a watering can or a hose with a mist setting so you don’t wash away any soil or damage delicate plants.

“Add mulch to help retain moisture around your plants. If you have plants in pots, try grouping these together to create a microclimate to retain moisture.”
