Watering plants is crucial during sunny weather10:49, 26 May 2026Alan Titchmarsh has revealed his key tip for watering plants in containers and pots. With the hot sunny weather, gardens need more attention than ever.‌Many gardeners will want to head outside to ensure their shrubs, flowers, and vegetables are well cared for. But, when it comes to watering, more isn't always best.‌Garden expert Alan said: "When it comes to container plants, you really are playing god. Although rain can fall down, it won't really water them terribly well."‌Alan explained that when it rains, the water hits the plant's foliage before running off. It means the soil and roots aren't getting as wet as you might think."So, you have got to make sure that your pot plants, in particular outdoors on a hot terrace in the summer, don't dry out," Alan said.‌It is important to check whether the plant is actually dry. Before simply reaching for the watering can or hose, Alan urges gardeners to put two fingers into the soil to check.He said in his Gardening with Alan Titchmarsh video: "Get down there, dig into the compost. Use your fingers to scoop down underneath." Alan demonstrated on one of his own plant pots, which appeared dry from the surface.Yet, once he dug slightly, he noticed the compost was "perfectly damp". He said: "It doesn't actually need any more water. If it is damp two inches down, leave it alone.‌"If it is dry, give it a really good soak." Plants that love moisture can still be watered, as Alan said, they can't be overwatered.Content cannot be displayed without consentWhen watering large plants, place the hose or watering can in the middle of the pot. It will ensure the water doesn't run off the foliage and miss the roots.Article continues belowAlan has previously shared his own recommendation for what flowers to add to your garden. He selected just one flower that is "easy" to care for and will provide a "summer of colour".The expert suggests picking up Osteospermum, which are also known as African or Cape daisies. They offer long-lasting, colourful blooms throughout summer into autumn. Alan said: "Osteospermum is a perennial, but it is tender."In the mildest gardens, those by the sea in the south west of England, they can come through the winter." Alan recommends planting them in mid to late May.
