The last DCF Scholarship Season saw a total of £14,000 awarded.
Previous winner, Charlotte Bancroft, of Merrist Wood College, said: "I could not have gained my qualification without the help of the DCF. The scholarship has helped me to pay for tuition fees, examination fees and travel expenses to college. It really has helped me in my growing horticulture career."
