I used to have big pots of maidenhair fern on the porch where they could get shade and, on principle, water. Whenever I came or went from the house I had to pass them and give them water when the soil was less than damp.
That was the theory, but in practice I would tear off to work, noting the pitiful state of the garden as a whole, and then drag back home after dark.
When the maidenhair had dwindled to a few pale fronds begging for merciful death, I composted them and transplanted walking iris into the pots for instant success. They sit on Prairie Style brick pilasters bookending the porch steps, and one of the pilasters has a big crack in its concrete topper. When the iris pots are watered, moisture seeps through the concrete.
This is a lot like the dripping cliffs of central Texas which are the maidenhair fern’s natural habitat. So, naturally, a fern has grown out of the mortar. It’s not a home maintenance error, it’s a marvel.
