You planted a hydrangea, it flourished all spring, but now on hot days its leaves are wilting. Hydrangeas are the first plants in the garden to suffer when the soil dries out. Give them a long drink, then mulch heavily; if they still sulk once established, move to a moister spot come winter.

Breeders just can’t leave clematis alone, resulting in ever-bigger blooms that won’t collapse at the first drop of rain. Join the clematis revolution by investing in new variety ‘Big Brother’. At 25cm across, its blooms are mammoth; even better, it flowers twice, in late spring and late summer. Height and spread 1.5m x 90cm. To order one jumbo plug for £14.99, or two jumbo plugs for £19.99, call 0330 333 6856 quoting ref GU359. Or shop online at theguardian.com/offers/plants. All orders include free p&p.
