Nothing but bunny fertilizer goes on my figs
since last year.
The growth is un believable. It can be used immediately
and honestly works better than any form of fertilizer I
have used.
I put it in the hole when transplanting, I use it on
everything growing I have.
That article keep stating the over use or over abundance of
phosphates or excess phosphates or over fertilizing with phosphates.
I agree, when over used it does more harm than good.
But when soil is lacking phosphates, it does help adding
minimal amounts back to the soil. Bone meal for instance
used in small amounts returns phosphorus to the soil.
