    I've got about 1/2 acre of St Augustine lawn back in the trees. Most of it gets enough sun to do very well. There's a 10 yard stretch at one end that will show signs of growth at the beginning of each season when the sun is lower but ends up the year as dirt.

    Looking for something that will grow in heavier shade and hopefully "blend in" with an otherwise nice St Augustine lawn. The area is irrigated.

    Well, st Augustine is one of, if not the most shade tolerant warm season grass...

    Forests and lawns do not mix. Trees need to be introduced to Mr Husqvarna or Mr Stihl. If not, the area not growing grass will have to resemble the understory of a forest with shade tolerant shrubs.

    It's not the shade. It's the soil. The runners will spread out across the bare area at the first of the summer and then die out right? Ground is to hard for the roots to dig in. Till up area and add some goooodddddd dirt. I use some old manure compost that has been sitting for 3-4 years. St Augustine literally spreads runners over it in a week and was solid with 2 months. Did this trick on 6 different yards this year all thought it was because of shade in a few spots it only received sun for about an hour a day if that.

    I hear what you're saying about soil but the entire yard is the same soil. This really is a shade issue in this area IMO. The growth in the Spring is more from the ground and less so from runners. More than half this yard was sparse/bare like this 7 years ago when we purchased because the previous owners never raked the leaves. The first Spring I cleaned things up and removed a half dozen trees from the space to open things up.

    Took one season for the grass to spread to a dense turf after that.

    This section of yard in picture 1 (current picture) over the fence behind the reddish chairs is about 10 ft above the runoff creek and I want to keep the trees on this edge by the creek to hold the plateau from eroding. That creek is typically dry but will get deep and fast very quickly in a heavy rain. I've actually built a 3 foot bag wall down at the base to push the creek away and stop some undercut that was going on.

    Off behind my wife in picture 2 (taken winter year 1 after the cleanup) on the other side of that fence is 100 year flood plain so I can't touch anything per the Town ordinance.....

    I've wanted to mulch or rock this small area for 5 years but have to deal with the boss ;)

    St Augustine will grow in shade. I have it growing in yards where it's almost 100% shade in a few places. However it's harder for it to do so. Also harder for it to spread. Add in hard ground and you get your bare spot. Yes your entire yard has hard ground. Grass is doing better in the less shaded areas right? So yes, call it a shade problem. You also have a hard ground problem. my suggestion from past experience. Solve the dirt problem or get your chain saw out.

    The first pic where the fire pit, chairs, and dog. St. Augustine grass does not do well in high traffic area.
