Sounds like you're caught between a rock and a hard place. With the leaves and acorns, fall seeding isn't much of an option, but with the heat, spring seeding doesn't give enough time for the grass to establish to live through the summer. It's too late for this year, but is dormant seeding an option? I'm not sure if your winters are cold enough, but dormant seeding is my best option. We have heat that lasts through September, then snow starting in October, so fall seeding doesn't work. And the time from snow melt to 90 degree days is also short, so spring seeding fails. Dormant seeding works well for me. If winters are mild enough, maybe you could even seed late fall/early winter. If the seed sprouts, maybe enough would last through the winter to get a good start. The cold itself doesn't do cool season grasses much harm. What harms them is when the ground freezes and thaws, disrupting the baby roots before they're established. Maybe with your mild winters that would be less of a concern.

Thank you for your comments about my gallery and blog. But both show a big problem of mine: I am not able to focus on one or two plant familys. My plant collection is a real mess, the spanish phrase "de todo un poco" applies very well. So I am doing many things but nothing properly.

We've all got things that keep us awake at night. But in my world, 9 or 10 feet until concrete is exactly the same as no concrete in sight anywhere. That is, I would never worry about such a supposed issue. My gawd, we plant thousands of street trees which would never make the cut if that were a limiting factor! Not yelling at you, Joe, just saying, it's good to think ahead, but don't let that thinking paralyze you!

Yes it's very thick heavy metal. It's fun to put those pretty little butterfiles in her net. The picture is a real (and alive) butterfly, I kept a low spot in the garden damp for them and they would just land there and enjoy the cool damp ground. I can't wait for them to come back!
