Marilyn, you have set up a very nice sitting area. I love it. I take back your container semp growing. You have good size pots. I have seen people put them in small pots and think they will be happy. I think you have a good size round pots that are good to grow your semps as long as you want in them.
I always wanted to have the room to plant as much of every plant I wanted so I needed a lot of land so I went in search for property that had acres of land. I was not counting on fighting deer, rabbits, hares, squirrels, racoons, groundhogs, a bear or two.
So caring for the plants and lots of gardens even at my old age is not hard. My hardest job is fighting critters.
I have a small tractor that I can haul stuff around the property and cut the grass. In the winter I hook the shovel on the front and shovel the walkway and driveway.
