The front of my house is, like many Haitian houses, where cement was mixed and left to harden. After I fenced in the space and started planting, I realized that there are several feet right under the window where there's still a large amount of hardened cement, gravel, and even, apparently, unmixed cement. Not only is it really hard to get through, it seems that in addition to our usual infertile soil, it's sucking up nutrients and moisture.
I've managed to move out most of the suffering plants to a friendlier location, but I'm trying desperately to make this space plantable. I'm burying organic material and compost and aged goat manure under more organic material and local soil. My thought is I'll try to raise the whole thing up about 18 inches or so with decent soil and plant resilient plants.
What can I plant there? Perennials, flowers or fruit or ornamentals. Under a high window (about 6 feet off the ground) and bare wall on each side. It is also the south side and gets a major beating by the sun each afternoon. I've planted an acerola cherry and a jackfruit to give shade, but they're young, so that will take time. It looks bare and ugly! Help!
I like them in a mass planting as a backdrop. They look like lace. But I don't love them so much for the front of the house.
I'm actually thinking of planting a few clumps of vetiver grass for structure and to chop-and-drop for mulch, then just set a half dozen large cement or terracotta pots out with various structural plants in them. Once the soil is improved through the chop and drop, I can plant something more permanent. Maybe . . . :)
