Rettendon Horticultural Society is over 130 years old, being founded in 1892. Its aim has always been to promote interest in all aspects of horticulture, although it is also now one of the few social clubs remaining in Rettendon parish. The society is a friendly organization which welcomes all comers to its events and activities. There is a regular calendar of events throughout the year, including three shows each year (in Spring, Summer and Autumn), talks on various subjects (not just gardening), and coach trips to places of interest.
