I really can't thank you all enough for giving me so many tips on what to do to kickstart my garden for the Spring planting season. I read through all the comments (and the emails I received) and have come up with a plan.
I'm going to remove the dirt from box 1 and shovel it into box 2. Anything that doesn't fit will go into our wheelbarrow. Then I'm going to use the Devil's Urine itself (Roundup) to spray a kill-zone under the area where the box sits. I'm going to put down a new piece of useless landscaping cloth (because I still have some and feel better using it up) and then I'm going to put down some large sheets of cardboard (that Farmer B was nice enough to drag home last night). Then I'm going to put the soil back in, top it up with compost and wash, rinse, repeat on the other box.
The final step to my plan is to buy some stepping stones from Home Depot and place them around the garden as tightly as possible. I realize this is futile because they won't fit perfectly and grass will grow up between them, but the fact that we have thick weeds and grass butting right up against the raised beds can't be good. I figure if the stepping stones at least reduces this by 50% it's a step in the right direction.
I don't know if this is the best plan, but I do know it's at least a plan that's heading me in the right direction. I hope to get it done today and tomorrow, but I'm allowing myself the entire week to pull this off.
Thanks again for all your wonderful tips and advice!!!
Here's a photo of Saffie that I took this morning out at the garden. She's ready for me to be back out there too!
