The James Coles Centenary Open Day: The Future of Amenity Plant Supply in the UK, scheduled for 19 September, will donate half the proceeds of ticket sales to HortAid.
The networking event features Tim Calnan of CS Design, who will discuss the future with building information modelling (BIM), the HTA's Penny Evans on promoting careers in horticulture and BALI's Wayne Grills on the skill shortages affecting the landscape industry.
The day will include practical demonstrations, seminars and nursery tours.
Meanwhile, New Hopetoun Gardens garden centre in West Lothian is organising a Gardeners Question Evening on 25 September, with all proceeds going to HortAid. Tickets cost £10. Dougal Philip, the new chairman of Perennial, is a trustee of the charity and the owner of New Hopetoun.
There will also be a HortAid zipwire sponsored ride at the Eden Project in Cornwall on 29 September.
An online fundraising kit featuring ideas such as a gnome sweepstake, is available to download at www.hortaid.org.uk
