Grimwood Garden harvest festival on 20 September — families welcome
14 August 2026 · By Boroughly editorial — AI-assisted, human-reviewed.
A free community harvest festival is coming to Grimwood Garden in Twickenham on Sunday 20 September, and families from across the borough — including Barnes — are warmly invited. The event runs from 1pm to 3pm and is organised by local conservation and community charity Habitats & Heritage.
The afternoon promises seasonal produce, children's activities and a general celebration of the garden's growing year. Grimwood Road is a short trip across the river for Barnes residents, and the event is the kind of unhurried, neighbourhood affair that tends to be much better than it looks on paper — think jam, homegrown veg and good conversation rather than a polished festival.
Habitats & Heritage also runs the Green Hub at Raleigh Road Recreation Ground in Twickenham, where two community planters — one of herbs, one of vegetables — are currently in need of watering volunteers over the warmer weeks. If you live or work nearby and can help, email [hello@habitatsandheritage.org.uk](mailto:hello@habitatsandheritage.org.uk); a free watering can is available if needed.
Full details of the harvest festival are on the Richmond Council website.
