Just looking at your lush lawn, you must be in the UK. What a beautiful garden. And you've done so much to make it not only "accessible" for your wife to enjoy, but you've successfully made it easier to care for over the years. I'm slowly learning to do the latter. My motto, especially for senior gardeners like myself, is to "Garden Smart". I try to chose carefree plants, plant them in failsafe spots (or in pots) and create a garden I don't have to be a "slave" to. Thank you very much for sharing your lovely garden photos. You're clearly "Gardening Smart".
