Uncle Ree Farm

Uncle Ree Farm is a small urban farm in Bang Duan, Phasi Charoen — on Bangkok’s Thonburi side — built around earthworm composting that turns food waste into fertiliser. It’s open only Sunday mornings, 09:30-12:00, entry is free, and groups are kept to around 10 visitors per session.

Experience

The core of a visit is the earthworm operation: three types of earthworms are farmed specifically to digest vegetable and food scraps, producing both solid compost and a liquid fertiliser that has become the farm’s best-known product. Founder Chari Bunyawinit — known locally as “Uncle Ree” — started the project in 2011 by converting a disused parking area into worm beds, and the farm has grown from there into a working demonstration of closed-loop, low-waste agriculture.

Beyond the worms, the visit takes in raised organic vegetable beds, a mushroom room growing milky mushrooms under an internet-connected watering system, and a small closed-system livestock setup — pigs, ducks, chickens and turtles — where the manure feeds back into the farm’s fertiliser cycle. Visitors typically get to taste a homemade pizza topped with the farm’s own milky mushrooms and sample kimchi made from vegetables grown on-site.

Atmosphere & Timing

This reads as a working demonstration plot rather than a polished agritourism stop — expect a founder-led, conversational walk-through rather than a scripted tour, and come with questions if composting or small-scale farming genuinely interests you. It’s not set up for a quick drop-in visit outside its narrow Sunday window.

Practical

The farm sits off Phet Kasem Road in Bangkok’s Phasi Charoen district, roughly 40-60 minutes by car from the city centre depending on traffic — a taxi or ride-hailing app is the simplest way in, since it’s off the BTS/MRT network. If you’re exploring this side of the city, Khlong Lat Mayom Floating Market and the Khlong Bang Luang artists’ community are both a short drive away and pair well with a Sunday-morning visit here.

Insider Tip: Call ahead (06 1414 5242) before turning up — with only a 10-person cap per session, a Sunday visit can fill without warning.

Watch out: There’s a single three-hour window each week to visit — arriving outside 09:30-12:00 on a Sunday means the gate is shut.
