"I was given one of these last year and have now bought my own for this year. I find it easy to interpret once I'd read the guide booklet, which is very informative. The calendar isn't quite big enough to keep notes on, but at least I can hang it on the wall to refer to. I find it helps me to connect better with the garden, and last year I was very pleased with the results - Not sure if this was all down to the calendar but its certainly better than having no structure. This year I'll try some side-by-side experiments."
