When the golden evening sun casts long shadows of GoodGymers arriving at Elthorne Park armed with spades, you know exactly what time of year it is: burdock-hunting season.

While burdock is a useful food source for pollinators, it is also extremely invasive. A single burdock can produce up to 15,000 seeds, allowing it to spread rapidly across green spaces. Left unchecked, it can grow to an impressive 10 feet tall, competing with other plants for sunlight, water, and nutrients. Its large leaves can block the sunlight from reaching surrounding vegetation. Apart from making it harder for a variety of plants to survive, burdock produces spiky seed heads called burrs later in the year, which easily stick to dogs, wild animals, and people's clothing, helping the plant spread even further.

The Ealing Parks Rangers asked for our help in tackling this botanical giant by digging out its deep taproots wherever possible or cutting plants as close to the ground as we could. Six GoodGymers answered the call. Richard, Yonas, Steph Ducat, Sevan and Kash ran 3.5 km from Ealing Broadway through West Ealing and Hanwell to meet Conor at Elthorne Park.

Armed with spades and determination, these Aces of Spades set to work clearing burdock along the path leading to Elthorne Terraces Orchard. Before long, they reached a true burdock stronghold and spent the rest of the evening removing as many plants as possible before they had the chance to develop burrs and disperse their thousands of seeds.

It was a rewarding session that made a difference to protecting the biodiversity of this much-loved Hanwell park. However, having discovered such a significant burdock colony, our work is far from over. We'll need to return before the end of the month to stay ahead of the invasion.

Fancy joining the fight against the burdock army? Come along to our session on 30th June!
