April arrives with a flourish! One minute we’re admiring frothy cherry blossom against bright blue skies, the next we’re reaching for a fleece to protect tender shoots from a sharp overnight frost. It is a month of promise — and unpredictability — but also one of the most exciting times to be in the garden. Sweet peas can be sown outside now. Prune penstemons and other slightly tender plants, divide herbaceous perennials.








Prune early-summer flowering shrubs, such as Philadelphus, once they have finished flowering. Cut back flowered growth to a strong lower shoot and thin out up to a fifth of old, woody stems.
