I am not exactly new to bonsai but I am relatively new to taking it seriously. Also, I am no stranger to gardening.
As a gardener I would periodically inoculate the soil around my plants with worm compost tea to help boost the beneficial soil microbes.
Nearly all of my trees are planted in a mostly rocky mixture with some amount of peat moss to boost acidity and improve water retention.
So my question is, while my trees are doing well over the last few years I am wondering if periodically using compost tea to introduce/maintain some level of soil microbes would be useful, harmful, or pointless?
