Tonight's task took us to the pond at Harmony Gardens. Mike explained that three-cornered leeks were running rampant, and we needed to pull as many as possible up control the spread. They can spread by dividing bulbs but also through seeds. Mike advised not growing them in your garden - but they make a tasty pesto!

Everyone grabbed a fork and got to work. Before we knew it it was 8pm, there were still three cornered leeks everywhere but we had made a dent.

We're heading back on May 20, when the three-cornered leeks will be over but Mike will find plenty of other things for us to do.
