Scotland, Rhu – Rhododendron Propagation Workshop




A Rhododendron propagation workshop at Glenarn to be led by Michael and Sue Thornley, garden owners since 1983. The workshop will include hands-on selection of cutting material, taking cuttings, propagation by seed, ground and air layering and renovation by cutting back of older plants.

This sheltered garden overlooking the Gareloch at Rhu is famous for its wide collection of rare and unusual rhododendrons. It was established in the 1920s & 30s by the Gibson family. Lying in a protected hollow, there is a Himalayan glen running its length providing shelter for large-leaved and tender rhododendrons. Early in spring tall Asiatic magnolias create dramatic interest while other plants such as crinodendrons, euchryphias and acers provide colour throughout the year.

A large rock garden, built around the old quarry and natural rock outcrop in the 1930s, gives a variety of habitats for a wider variety of smaller plants. The garden also has much used greenhouse, a new shade house, beehives and a fruit and vegetable garden.

When Mike & Sue bought Glenarn it was quite overgrown. They have laboriously and lovingly restored and enhanced the garden. They have also used it to offer gardening training, both to HBGTP students and WRAGS.

​The Cost of this workshop is £50 for members, £55 for non-members. Please bring a packed lunch, hot and cold drinks will be supplied as well as cake/biscuits.  Please bring secateurs and a small craft /Stanley knife.
