Planting my leek seedlings into the hard soil required the help of DB. He needed a metal mallet to hammer in our large leek dibber (the wooden shaft and handle of an old spade), and a huge amount of effort to twist it out. The hole stayed open and I dropped in a leek.
Just 7 leeks later (out of 20), we gave up. The temperature at 28.8C, coupled with high humidity was just too hot to work. The remaining leeks were put into a jar of water and will be finished tomorrow.
It is forecast to get hotter over each of the next few days, I am not looking forward to it at all.
