Perennial highlighted the issue and increased awareness of its Lironi Training Fund during National Gardening Week on 15-21 April. The fund is intended to help students and those already working in horticulture who need financial support for training.
It includes bursaries for those facing unforeseen difficulty and for children of horticulturists, grants for short courses to progress careers and retraining funds for horticulturists in hardship.
Perennial chief executive Richard Capewell said: "It is vital that we invest in the future of the industry by encouraging the next generation to choose horticulture as a career. Many young people simply don't know the options open to them and in the current economic climate are finding it more and more difficult to finance their training.
"We want to open the door for young people considering a career in horticulture and encourage people already studying or working in horticulture who find themselves in difficulty to carry on in this industry."
