Q: But, I don’t like stone - it’s so cold!
A: Well, then, you have to learn to live with the problem. That is, you cannot beat the artillery fungus (at this time), so manage it. Use mulches that the artillery fungus doesn’t like, such as large pine bark nuggets. Then, put down a fresh layer of mulch each year – we have no evidence for this, but yearly applications of layers of mulch really seem to inhibit the artillery fungus.
Another possibility, but one we haven not investigated, is to use ground cover such as ivy, periwinkle, or pachysandra in place of the mulch around your foundation. It seems likely that the artillery fungus would not grow well under the canopy (on the fallen dead leaves) of such ground-cover plants. Or, establish lawn right up to your foundation. An artificial mulch made of plastic, old tires, etc. should work, but we have not tested it.
