Many gardeners will be keen to head outside to ensure their shrubs, flowers, and vegetables are properly looked after. However, when it comes to watering, more isn’t always better. 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 during rainfall, water falls on the plant’s foliage before running off — meaning the soil and roots aren’t receiving nearly as much moisture as you might expect.
“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 vital to check whether the plant is actually dry before reaching for the watering can or hose. Alan urges gardeners to push two fingers into the soil to find out.
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 using one of his own plant pots, which looked dry on the surface.
Yet, once he dug down slightly, he discovered 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 thrive in moisture can still be watered freely, as Alan noted; they cannot be overwatered.
When watering large plants, position the hose or watering can in the centre of the pot. This will ensure the water does not run off the foliage and miss the roots.
The gardening expert suggests picking up Osteospermum, also commonly known as African or Cape daisies. They produce long-lasting, vibrant blooms throughout summer and well into autumn. Alan said: “Osteospermum is a perennial, but it is tender.
