Tell me about it. Seeds that fall into more broken soil will also tend to germinate well due to the damper conditions at the bottom of the cracked soil.

Inevitably, plants do well where you don't want them to. I have cleome that grow beautifully in the lilac's space across the yard from where I let the cleome grow wild. And I have Easter Egg plant that simply grows everywhere, but I don't really mind that, or the volunteer Melampodium.

I have a pretty green thumb but if you want to kill lavender or french tarragon plant send it to me. I cannot get either of those to survive.

I was trying to edit this post & clicked the wrong heading duh-uh. so the thread read... if you want to guarantee grass seed germination sow it in a flower bed or concrete expansion joint. every errant seed that hit the ground grew. some clumps ( fescue ) were so healthy that I transplanted them into the lawn.
