Clean Up River Brent (CURB), led by Ben Morris, has been very successful in recent years in removing Himalayan balsam from the banks of River Brent. What is Himalayan balsam, and why would anyone want to get rid of it, you may ask. The plant, native to the Himalayas, was brought to the UK in the 19th century for its ornamental qualities. Over the years, it became dominant on many riverbanks across the country. If left unchecked, the invasive balsam can exclude other plants and decrease biodiversity, as it’s not compatible with species living around it. This tallest annual weed (reaching even 3 metres in height!) dies each year and leaves no roots in the soil, which does not help hold the soil together and stop silt from washing into rivers. Silt, in turn, decreases water quality by blocking sunlight from reaching the water and helping spread pollution.

CURB’s plan for 2026 was to reduce balsam in Ealing to zero, and GoodGym Ealing were excited to find a Saturday to help Ben and the team with that ambitious mission. One walker, two runners and four cyclists from GoodGym met the regular Balsam Bashers at Brent Viaduct to walk up- and downstream the river and scour for baby balsam to curb it (pun intended) before it grows and flowers.

James, Richard and Kash went with basher Rachel to visit last year’s balsam hotspots, including a vast area GoodGymers helped clear in 2025. Rachel and Kash, who had done bashing in the nearby locations the previous year, were astonished by how much the place had changed. It was so hard to find any balsam - that might have felt unsatisfying to the bashers, but at the same time, it was proof that the strategy of fighting the invasive plant was working very well. Meanwhile, Sevan and Jo went downstream and found equally low numbers of balsam. With such slim pickings, part of the team - Ash and Amy - were redirected to litter picking, as rubbish in the river seemed way more abundant than the Himalayan invader.

The whole party came together, and regrouped after 90 minutes, as it was nearly impossible to spot any more balsam - the last year’s teams did so well! Resourceful Ben, having spotted “accessible rubbish”, proposed to GoodGymers to spend the last 30 minutes of the session on a litter blitz in the shallow part of the River Brent. The GoodGymers agreed, and in a very short time, retrieved a bag of rubbish each, and hauled some soaked, flytipped duvets - what an impressive and disgusting find!

As the area has mostly recovered from balsam invasion, CURB is now planning to use its budget to buy native plants to plant in selected areas once the balsam has been eliminated. Watch this space for the future sessions with them.

Friends of Waterman’s Park had a grand vision. Forget boring planters or a generic wildflower meadow. Enter the Dragon... path! The Green Dragon Path was going to be planted in a wildflower area, currently overtaken by grass. The creative vision came with a design on paper - what better way to attract adventurers than a map to a dragon’s treasure waiting to be uncovered!

Maria walked all the way from Hackney to Brentford to be part of this grand community endeavour, created in partnership with Green Dragon Primary School (how cool is that for a school name!). Amy, although new to GoodGym and West London, already had a couple of local volunteering tasks under her belt and couldn’t miss this one, so she cycled to Waterman’s Park too. Finally, Sevan and Kash - already having found some dragon figurines in the morning and gone on a Hobbit-style quest at noon - were up for anything that involved dragons and magic. All four GoodGymers were exactly where they needed to be.

After a bit of anticipation - while the visionary lead explained the approach, the mower was connected, the right tools arrived, and parents with children joined the effort to bring the dragon to life - everyone got to planting.

The soil was dry and hard, full of rocks and bricks, and it wasn’t easy at all to dig into, even for the smallest flowers. Luckily, the more powerful tools soon arrived and changed the course of the session. Sevan and Kash, already familiar with mattocks and pickaxes, were delighted to see the right tools to break through the impenetrable ground. One of the volunteers, Seyed - an embodiment of skill and strength - took mattocking to the next level, helping others dig holes and unearthing an impressive block of concrete, which later found its resting place in the Thames.

Maria and Amy, initially reluctant to admit their undiscovered love for hacking into the ground with a mattock - saying things like “You’re the strong one, you do it” or “I prefer a smaller, more gentle tool” - quickly changed their minds once they gave it a go. The mattock and pickaxe proved irresistible, and soon the pair were sending tremors through the soil that seemed to awaken the sleeping dragon. The mystical creature came to life, with flowers and spiky ornamental grasses shaping its winding body, head, and fishy tail. What a wonderful creation for the community it was!

The Early May Bank Holiday weekend sounds like a time when everyone wants to get away to enjoy a break, right? Wrong! A revolutionary team of 12 GoodGymers descended on Horsenden Farm, redefining Italian cuisine and the rules of landscaping.

Such impressive numbers guaranteed at least a double task, so the team split into two. Sevan, Richard, Thaiza, Amy, Maxime and Afshin went up Horsenden Hill to marvel at the views while dealing with treacherous spikes, while Penny, Danny, Kat, Steph Ducat, Augustin and Kash headed down to the car park to make a very special lasagne.

The first team continued the task started last month at the top of the hill. The goal was to remove as much prickly hawthorn as possible to make space for the Horsenden cows to graze and enrich the ecosystem with their wonderful cow pies - a buffet for countless insects, fungi, and bacteria, and a source of nutrients like nitrogen, phosphorus, and potassium for plants to grow.

With thick gloves and loppers, the six GoodGymers finished off the leftover hawthorn from April and moved on to the next patch, where the newest addition to the team, Amy, spotted a memorial sign and cut through the spiky plants, determined to find out what was written on it. What a start! Amy met us last month at another outdoor task, so we knew she'd fall in love with losing herself in Horsenden's nature. Welcome, Amy!

The hilltop team destroyed the second hawthorn patch in no time and moved on to make a start at the third one, which they had to leave unfinished. Throwing the tangled, spiky cuttings over the fence and pushing them down was not a quick and easy job as one might think. The group made great progress, with some hawthorn still left behind for the next volunteer group.

The second team was a team of cooks. As you can imagine, things can get tricky when you get too many of them. To add to the complexity of the intricate lasagne recipe we had to follow, we were boosted by two additional cooks (other Horsenden volunteers). Luckily, Elsa, our task owner and chef, joined the group to masterfully coordinate the execution of her staple recipe:

Compost Lasagne

(Serves: 1 happy ecosystem)

Prep time: As long as it takes to fill a wheelbarrow
Cook time: A few months (slow food at its finest)

Ingredients

• 4 parts “green waste” 🌿 (plant trimmings + signature “lasagne sh*ts” a.k.a. manure)
• 6 parts woodchip 🪵
• A willing team of GoodGymers

Equipment

• Pitchfork 🍴
• Shovel 🥄
• Wheelbarrow 🛒

Method

1. Lay down a generous base of lasagne sh*ts. This is your rich foundation.
2. Sprinkle a layer of plant waste over the top. Think of it as your herby middle layer.
3. Cover with a thick layer of woodchip to seal everything in and keep things nicely balanced.
4. Drizzle a light splash of compost béchamel (questionable brown liquid) over the layer.
5. Keep layering: manure, greens, woodchip, 2 to 3 times, or until your compost lasagne reaches impressive heights.
6. Let it rest - leave your masterpiece to slowly “cook” down into beautiful compost.

Bon appétit (for the soil)! 🌍

Chef’s tip

The secret ingredient is teamwork and not taking yourself too seriously.

After assembling three impressive lasagne, we left nature to do the rest of the cooking. We then all headed for a well-deserved team lunch, which offered an equally unconventional take on Italian cuisine: pizza with a pickle and egg!

If you think that sounds like a fun thing to do on a Saturday morning, join us next month at Horsenden Farm!
