Yep, #gardenjournal is perfect!!! It's meant to be the first ten days of every month but I can't be bothered policing it. It's now just grown to people talking about their gardens so who cares haha.
What an exciting blank slate and I can't wait to see what happens. I'd shy away from ivy as it can cause damage to walls. The little rootlets dig into the mortar. What about passion fruit or something edible? Or espaliered fruit trees?
I'm not worried about the damage on the walls, but we have great varieties of passion fruit that grow here and will probably do well. I'll just get one of each and will have the most wonderful arrangement of flowers on the wall! Oh, and a grid for them to climb up on, I need that, too. Thank you so much for the idea!
