To toy boy, add 20 year old son. 
I was a gardener in my last profession, until I got arthritis. Over the 8 years since we have been here, I have gradually added raised beds, and every year more borders and beds are dug and potted up, dug over and manured, membrane put down and the plants are replaced, then covered in bark chippings or gravel. I would love to be able to wave a magic wand and for it all to be finished, but finances prevent it all being done at once, and soil is not all that easy to come by for filling the raised beds, although I do make an awful lot of compost each year. I found my local coal merchant delivers bags of compost for £35 per ton bag, which is a godsend. It is DS's job to barrow it to where it is needed, DBH makes the raised beds and digs out edges, I do the rest as neither are any good at removing groundelder roots as they dig. I also get them doing all the hedgecutting and high-up pruning, as I can no longer stand on a ladder for any length of time whilst holding a chainsaw.
One of my favourite gardening tools is this www.amazon.co.uk/Spear-Jackson-8200RS-Razorsharp-Pruner/dp/B002W6YYXY
It's a long-handled rose pruner, that will hold the pruned branchlet so that you can place it in a trug, ideal for pruning my pergolas. It only cuts through branches that are maybe 2cms or 3/4" in width. I love my roses and it used to depress me to see them and know I couldn't reach them easily, as even stepladders are a struggle now.
