Laziness led me to stop using cat litter on my hedges... that and the disappointment with some of the rocks falling off my first batch. Deciding to omit cat litter has made the process of hedge making faster. I have another six feet that will be finished by tomorrow morning.
I wanted to show the difference between my first and second batches. Due to my own decision not to write my recipe down, I accidentally bought the wrong base size. As you can see, it is thicker. This has made for some wider hedges.
I am still very pleased with them though, and they don't look too bad when lining a road.
