So many beautiful things to compliment your garden, like the bird nest! or the growing tomatoes, the peppers, well done, for everything.
With the banana peel, I do that as well, but I cook them for half an hour or so, so the boiling water really blends with the nutrients of the fruit skin. That is great for the production of flowers.
I really hope that my Lemon tree grows to be like yours.
¡Take care! greetings, friend.
