The gardens at Great Comp Garden, close to Tonbridge, Kent, were established in 1957 by Roderick and Joy Cameron and opened to the public in the early 1960s.
The gardens, famed for their Salvias, surround a 17th Century manor house and both were put in trust on Joy Cameron’s death in 1982 so that people could continue to enjoy them.
Now curator William Dyson is calling for volunteers to attend its first volunteer day on April 5.
He said: "We hope that our Volunteer Day will be a great opportunity for people to enjoy the gardens and see what we do here at Great Comp. The Magnolias are in bloom and the garden is looking fantastic - the sunshine has brought on the bulbs and there is plenty to see.
"However, the storms of the last winter brought down 19 trees and we’ve been sawing and chipping them for some time now. The garden looks great but we’re looking for some help in spreading the chippings on the new pathways and to undertake light garden duties in the flower beds in preparation for our first event of the season".The quirky gardens, which include an Italian Garden, romantic ruins and woodland walks are run by two full-time and one part-time gardener.
