Mix the Worm Attractant into the top 100-150mm, 4-6", and wet down well with water, if you have Worm Juice it's best to use a 1:5 Juice/Water mix. Then cover with a mulch. Keep moist and wait, about 4-6 weeks in unfavorable conditions. When expanding the area simply put the mulch out 150mm, 6', at a time around the area every 2-3 weeks. While this method is slow, it is relatively cheap to do.
