The national charity helps retired or one-time horticulturists or their spouses who have run into financial difficulties.
Notcutt, who has been a trustee of the charity for seven years, addressed the sector at the end of last month during the annual British Tomato Growers' Conference in Coventry, where he urged growers to become "the eyes and ears of Perennial".
He said: "This is the first time we have gone to this sector. Perennial is here to help you - it covers the whole horticultural sector.
"We have a problem finding horticulturists in need. It is not easy to find these people because the charity has a very narrow scope."
He continued: "The most likely people are your own staff, so I would ask you to consider whether this is something you can use. It covers the whole of horticulture, including growers of edible crops.
