It's been over 50 consecutive days - and counting - without any rain in some parts of London, and Western Road Urban Garden in Southall required a constant effort from Janpal and volunteers to help the site keep up with the ongoing heat. The exotic vegetables inside the polytunnel were doing well, and the veg plot we had cleared, woodchipped and partially planted only a month ago started already producing crops such as aubergines and tomatoes! None of that came without a price. Manual watering of veg beds took a lot of time and energy and wouldn't be sustainable in the long term. That's something the architect of Western Road community garden Ash wanted to address for a while.

In February this year, we had taken first steps towards executing Ash's vision of installing two 1000-litre rainwater containers. The mud wasn't going to serve as a reliable base for a tonne of water in a single container, so after digging out the soil, we'd been looking forward to pouring the concrete into the square spaces for a few months. Today was the day to make Ash's vision reality!

Seven GoodGymers came to support Western Road on a Saturday morning in August:

• Walkers: Angela
• Runners: Sevan and Kash
• Cyclists: Scott, Amy and Steph
• Cyclists/parkrunners: Richard

The Plant Squad

Angela, Amy and Janpal had plenty of tasks to do: from weeding the bed alongside the polytunnel, to harvesting and watering the new veg plot. In the polytunnel, they discovered a watermelon that looked pretty good on the outside, but a closer look revealed a small hole and the fact that the fruit was half eaten inside! Judging by the size of the hole, it looked like a rat, rather than Mr Fox, was the prime suspect this time. To save the other juicy crops, Janpal ordered the harvesting of the green tomatoes before the rat laid its eyes on them. Amy found some very long chili peppers, and everyone had a chance to see ripe snake gourds.

Janpal's top tip for cooking a snake gourd:

"Make sure to take the skin off and discard the seeds. We haven't done it last time, and that was the most bitter thing I've ever had!"

The Concrete Cowboys

The group keen to learn concreting skills joined Ash and started with combining the mixture for a base for the water container:

• 4 parts shingle
• 2 parts coarse sand
• 1 part cement
• plasticiser.

While Steph, Richard and Sevan mixed the concrete in a tray to wheelbarrow it to the destination hole surrounded by a wooden frame, Scott, Kash and Ash cleared the weeds inside and around the frame, assisted with pouring the mix, then levelled and tamped the concrete.

The team used up all the resources allocated for one of the bases, then threw in some rubble to bulk up the base, but there wasn't enough material to finish off that stage of the project. Despite great teamwork and solid progress, we'll need to come back to finish off the job when more materials are available. Join us next Wednesday!
