(The worst clay soil I've ever worked with - San Juan, Puerto Rico)
Hello. I'm renting a townhouse in Germantown, MD and our soil has quite a bit of clay in it. Because I'm renting, and we plan to move in 4 years, I do not want to put a whole lot of money into my tiny front yard. We tried sowing grass seed but nothing really took. I planted some red blood plans which grew very well. I also planed some lavender and sage. Neither one grew, nor did they die. My question is should I keep to a container garden since nothing seems to be growing? Or perhaps there are plants and flowers that do well in clay soil. Any advice would be greatly appreciated.
Thanks!

I think Jasmine should do both - I love mixing container gardening with a conventional garden. Sure, she could just plant in pots, but I don't want her to let clay soil intimidate her one minute longer! Clay... people hate clay soil. When dry, it looks like an overbaked brownie - crusty, full of cracks, and water beads off of it, refusing to penetrate. When wet, it is a heavy, sticky mass that is a better used as a building material than a growing medium. It holds water like nobody's business and takes forever to drain. Yuk! Who'd want that? Well, (and this might make Jasmine happy) clay soil is incredibly nutrient rich. If you could just change the texture of clay soil, you'd have yourself some powerful stuff to grow a garden in. Now, changing the texture of your soil sounds hard, but it isn't. First and foremost, compost. Compost your heart out. (and by compost I mean spread organic compost on top of your clay soil. You can even lightly dig it in, if you're feeling ambitious. Making compost is another activity, for another post). Another thing you can do is buy a coffee can full of red worms (the kind people use as bait) and throw those babies on top of your compost layer. They will be your little diggers, tunneling into the clay soil below the fluffy compost and mixing the two up as they go ... eating up bits of organic matter and pooping out that miracle substance known as 'worm castings'. Your clay soil will begin to have lift and life, like a great hairdo!
