At the Bowmanville Zoo, director Michael Hackenberger shows Grahame how they turn elephant manure into compost.

Next, at the Ontario Science Centre Grahame talks with David Gunthorpe of Interior Landscape Products about beneficial insects.

Then, at New Zealand's Christchurch Botanic Garden Grahame learns about propagator Andrew Hodge's hobby: raising mutant Cacti.

Finally, Grahame shows us how to divide and plant Irises.
