My soil has too much of every nutrient except nitrogen, of which it has close to none. I have been adding blood meal to the soil. The internet states it is fast acting IF the soil is warm. Mine is, so:

1. How soon will I see a difference?

2. Can blood meal be put in a hose sprayer and sprayed right on the plant?

3. If it can, at what setting?

Thanks

Bloodmeal is not soluble so would probably clog any sprayer.
Worked into the soil around plants---it probably will take a week or two before you see results.
It has to break down before plants can use it.

OK, thanks, because it said online it worked fast, I was expecting results the next day. So, it was disappointing. Now, there is hope again.

Keep in mind, that though blood meal is a good, low-impact source of nitrogen, it can attract animals such as dogs.

I have everything in a garden cage because of the chickens.
