should one dig out to be on the safe.side?

If you use Mycorrhizal fungus sachets then it must be in contact with the
roots, best to wet the roots and powder them with it before planting.
Monty Don gace a demo of this some weeks ago in GW when he planted bare root
roses dusted with Mycorrhizal fungus.Then he gave them a big watering after
planting, whuch surely would hace washed the fungi powder off the roots
which he had just dusted a few minutes earlier.
If he had the soil firmed down then the fungus wouldn't have moved far
from the roots.
