It's taken some time, but finally, the sidewalk is looking miles better than it did. From this mess, to new trees, planted today by the Council - yay!
Seems Charlie Pisasale's offer came good, an I didn't have to wait too long. Kim, the guy I had been speaking with at the Council, texted me the day prior, to say the guys would be coming to put the trees in next day. Then, when I was out feeding the chooks the very next morning, he turned up to check where I wanted them. How thoughtful - I was impressed.
So he marked the spots, as below, and when I came home from work, lo! There they were - and a decent size too. I thought I might end up with tube-stock, but nope - these are really great. I will apply for two more next year!
