The sweet peas are now outside on the back porch 100% of the time.
You might not be able to tell from these photos, but there are small buds forming low down on the stalks, suggesting that they are happy in their new home and are branching out after being pinched back!
On a related note, the peas (snow and sugar snap) are coming up under the wire mesh that I laid down. It’s working to keep the squirrels out.
I suppose I can just leave the wire mesh down and let the peas grow up through it?
