After much pondering... sometimes it takes some time for me to get a thought into action... I started clearing a spot and digging.
After softening it with lots of water.
Picked out some seeds.
Now I have to repair the main line of the sprinkler system that i apparently cut with one f my tools. There's a 78 cent gadget that should do the trick. I just have to summon up some bravery and get it fixed. More details to come.
