probably not a good idea. At 1/4 tsp per gallon, it may not
interfere with the symbiosis at all. Two handfuls of bonemeal
or rock phosphate in a planting hole is in theory a lot of P for
a tomato plant, but it breaks down so slowly that any
mycorrhizae are going to be well established in the rhizosphere
by the time enough of that P is available to the roots to inhibit
the fungi.
So, I planted my peppers this year with a 1/2 cup of triple super phosphate mixed into each 5-gallon bucket. Would it be unwise for me to apply a soil drench of mycorrhizae and actinovate two weeks later?
