How can I persuade worms to cast their casts in garden spots other than my
lawns?

Golf courses use a proprietary fluid which is diluted to a specified rate
for a specified area. It is quite expensive for what it does, and usually
preferential for the greens and surrounds etc. Stings a little if in a cut
so possibly acidic.

Worm casts are very useful for planting in. If you have loads then as others
state use them in your compost
Other than that
