Since up until recently I had to deal with acid rain, wood ashes were an important part of my garden soil amendments, I incorporate compost into the gardens between each crop. With long term and perennial crops, it gets used as a mulch and top dressed with fresh grass clippings. Thus wood ash is constantly being applied in small amounts.
I plan to try some coffee spray to see what happens.

Since insects generally prefer unhealthy plants the pests become less of an issue. If I had a source for large amounts of organic coffee grounds I would add a lot more.
