anyone fertilize garlic with kelp?

[tjg911]

while it's too late this season i'm asking so next year i'll know.

in "growing great garlic" by ron engeland he mentions fertilizing garlic with maxicrop which is powdered kelp. my notes are not clear if this is a 1 time thing in early spring when the plants are 3" tall or if you use it every 2 weeks. he does say to foliar feed with fish emulsion every 2 weeks from 3" tall to early may then stop the fish emulsion. my notes sound like you use the kelp every 2 weeks also but i'm not clear on that.

the cost of powdered kelp is 3.5 pounds for $17! if you use powdered kelp:
1. one time application or every 2 weeks?
2. how much do you apply?

i use neptune's harvest fish and seaweed emulsion so maybe i'm already covered as it's in the mix?
