Making a diluted tea with this material and dipping the orchids in this will work well. I have had some success with my mini-orchids and I use a formula of 1 cup vermicompost to 1 gallon water, leave it 'brewing' in a warm area for a week then drain off the liquid and add 50:50 with water. This I then use for the orchid dip and even a weekly regimen of foliar fertilizing on some hard leaf orchids .
