Using watering can, per gallon of water:
1/4 cup liquid fish emusion
1/2 tsp. Kelp powder
Using foliar sprayer:
Also add 1/4 tsp. sticker-spreader (surfactant),
added last into the tank to avoid excess foaming (see
Resources section).
In a bucket, mix ingredients with a small amount of
water, first making a paste to avoid clumping, and
then dilute with water for application. For basal
