Why the paulownia may be the tree of the future

The paulownia, or empress tree, is good at surviving drought and hosepipe bans. Others may need your help
Paulownia tomentosa

As soon as the British drought began to unwind, gardeners were hit with a ban on hosepipes. Why is there not a ban on watering golf courses? Golf is said to have begun in Scotland as a game played on a sandy beach. If the climate is intensifying, should we stop watering greens and fairways and return the game to its dry roots in history? One well-watered golf course equates to hundreds of watered beds of plants.

To give my hose-banned garden a better chance, I have resorted to strategies learnt from hard experience. Just before the ban, I ran a bath, my first for a while. I left the water plugged in, washed off my earthy accretions and, as in the dry 1970s, transferred the water bucket by bucket to plants at risk in the garden. A big bucket, carefully poured round the roots, gives a tree a better chance of surviving until rains return. Little and often is a bad way to water. I now have buckets in the washbasins and the kitchen sink, waiting to treat trees to a top dressing of soap, scraps and toothpaste.
