Thanks for that tip ... same happening here so will dose it with ash and see what happens.
Just be careful in how much ash is spread on the lawn. A little is good, a lot is not necessarily better as it changes the ph of the soil. We have been donating our ash to a neighbour who tries to grow grass under his pine trees. The ash changes the ph of the soil so that relatively healthy grass can grow ... not as robust as his grass in other places but definitely better than before.
I second this. I have one pine tree left in my yard, and the ashes are placed under it, as well as in my garden. Pine needles are acidic, ash residue is basic (base).
When people made their own soap centuries ago, you didn't buy lye in a can. You ran water through wood ashes and continued to use fresh ash until an egg or potato would float about midway in the water. At that point the pH was basic enough to saponify the fat. (we make soap at home, but I use the canned lye )
