Depending on where your lawn is, you may not have to worry about your lawn for a while.

Once the ash settles, that is one thing, but if it rains, the rains will cause ash-water streams that will clog and burst.

Yes, the ash is good for renewal of life after a devastating period of time. It is just a matter of getting through that devastating period of time.

Have a great weekend!
Steem on,
