The arrival of the railway changed life in Swanley. The town became the location of Swanley Horticultural College which opened in 1887 and led to horticulture becoming the predominant industry. The college originally only catered for male students. Then in the early 1890s the first female students were admitted. Local Nurseries and florists' outlets blossomed, while casual farm labouring job opportunities on farms became in short supply. Some properties in Swanley still have apple and pear trees in their gardens from the original orchards. The college amalgamated with Wye College near Canterbury in 1945 under the governorship of Lord Northbourne.
