Fish fertilizer for blueberries?
My new highbush blueberries planted last fall are in a peaty/clay mix with pine needle mulch.
They are a bit yellow with some bordering orange, and figure a light fertilizer application would be of benefit before the mulch breaks down enough to add anything.
They leafed out, some producing berries, but very little growth.
How about half or even whole strength Alaska fish fert?
Or would granular "fruit tree and berry food" (4.10.10?) be ok?
