Four landscapers will take part in the web forum on 21 March, providing the public with the opportunity to ask questions about gardening and design.
The forum will take place on the Shoot website, at www.shootgardening.co.uk, between 9.30am and 12.30pm.
Members of the public are invited to publish questions and photos on the Shoot forum during the event and then the panel of APL members will be available online to provide advice in real time. Questions can be posted a few days earlier if interested visitors are not able to log on to the live event.
Panel members are APL chief executive Jason Lock, Broadview Garden Design director Matt Nichol, Bell Gardens managing director Andrew Tomes and The Gardenmakers director David Sewell.
The panel will answer questions across a range of landscaping and design issues such as using different materials, the costs of landscaping projects and dealing with problems such as level changes.
Lock said: "This forum, the first of its kind, will provide the public with the opportunity to ask the APL panel any question they may have relating to landscaping.
"The panel will be answering questions and exchanging ideas in a real-time and visual environment.
"This initiative provides APL members with a platform to talk directly to the public about their areas of expertise."
Shoot director Nicola Gammon said: "Shoot has polled its members and visitors, and found there is an enormous demand for gardening advice - from the initial planning stages of a new garden to how to care for and look after your garden once established."
