My husband and I have been in our house for 3 years now. We have a nice sized back yard, about 1/2 of it is devoted to a vegetable garden and I have a big bed in the front that also gets veggies/berries (have to make use of every inch of sunlight in our tree-studded neighborhood).
Problem; the back yard had basically gone fallow for ages under the previous owner. It wasn't watered enough in our desert climate and the crabgrass claimed it all. In the front, the neighbor's crabgrass is constantly sending over scouts. I have strawberries there, so it is difficult to get in there and pull the runners without disturbing all the berries. An obvious solution would be to do the strawberries somewhere else, but there really isn't anywhere better (as far as the grass or sunlight is concerned).
The first year, I turned the whole back yard and pulled two 40 gallon garbage containers of runners. The garden was OK, and last year we built raised beds with cardboard underneath. Thought that might keep them at bay. Nope. Now I have runners coming up under the bed, and I simply can't keep the grass out. This is only sort of a solution; every time I dig them out, I end up chopping up runners for the next generation.
So, anyone have any fantastic, miracle solutions to winning this battle? Everything I look up isn't very hopeful. DH sprayed conventional grass killer in the areas of the yard we don't garden to try to get an upper hand. That helped, a little, but I am not comfortable with this solution in the garden.
HELP! I need reinforcements!
