This works well.

I suggest hand feeding as this prevents the risk of impaction by swallowing substrate along with the food item. When it comes to the crickets, this also helps keep crickets from being left in the cage which if they get hungry will chew on the frog.

The dirt in these pots often contain fertilizer or pesticide residue so the dirt has to be totally washed off before the plant is used.

Yes but it usually not necessary.
