Earlier today, I took a bit of time and moved a flowering plant that I suspect is a phlox of some form from the weed-dominated area in front of my house to the area that I'd previously planted some irises and other flowering plants. I gave it a good soak and covered its base with mulch. It'll get the same treatment as the rest of those plants for the next few weeks, which means it'll get watered at least every couple of days.
Tomorrow begins the big plans for the south side of the house and the prairie garden. I'm planning on tearing out all the big weeds, turning the ground over and covering the area in landscape fabric. If I can did up some cardboard that isn't being used, or some newspaper, I'll toss that in under the landscape fabric as a soil enhancer. I may try to empty part of my compost pile/brush pile into the area too, depending on how bad the soil is.
Once I have that done, if I have energy left, I'll dig up a plot in the front lawn where I plan to put a prairie garden next spring. That will get landscape fabric over it as well, to make sure no weeds get an early start before the prairie plants can get established. I'm thinking I might either add some soil to the area, or otherwise build up a bit of a berm (by tossing some rocks and other fill from the south side of the house in and covering with soil) to set the prairie garden up a bit from the rest of the lawn. That's probably a bit much for tomorrow, though, and not something I need to decide before spring.
