I didn't move down here to care for a garden- and I've been known to say that if it were my choice I'd return most of it to the rough meadow land it used to be- but one gets drawn in. Yesterday I planted seven trees- five hawthorn and two magnolia. It's very satisfying to plant a tree.
And having planted something you feel a responsibility towards it. Which means trips to and fro with a watering can. You keep checking to see how it's doing. Are those leaves about to unfurl? Will it flower this year? And so one thing leads to another.
No, I'm not going to become a gardener. I'm not robust enough and I have other interests- but I can see why people give their lives to it.
