Staff from Wyevale Nurseries in Hereford will walk 30 miles on Saturday, June 7, to raise money for Greenfingers.
Sales and marketing director, Adam Dunnett, said: "We thought taking part in a sponsored walk would be a great way to raise money for Greenfingers.
"The charity does such fantastic work creating and improving the gardens at children's hospices, which are invaluable to the families that use them."
The 15 staff will walk the Mortimer Trail, which starts at Ludlow Castle, crossing the River Teme before going through Haye Park Wood and Deer Park.
Upon reaching the British Iron Age hill fort at Croft Ambrey the team will then join the River Lugg which will take them to Shobdon Hill Wood, before finishing at Kington.
Mr Dunnett added: "This walk will be a challenge for the team, but it does have amazing views. We hope to raise more than £1,000 for Greenfingers."
