Trichoderma harzianum strain T-22 is a biological fungicide and a root enhancer in the same jar. While predatory mites guard the leaves, T-22 guards the root zone: it colonises the root surface ahead of the pathogens, takes the space and the nutrients they would have used, parasitises the pathogenic fungi directly, and triggers the plant'...

I reduced fertilizing because after applying it, the plants do not show any nutrient deficiencies. I think it was a good decision because at this time last year my plants were already getting sick. The ordering process itself was trouble-free, and I waited about a week for the delivery, but it was worth it.

It's my first time using Trichoderma solution as a bio-fungal agent to prevent damping off. This stuff is great. I've already had success using it as a pre-soak and soil drench to germinate adeniums, aloes, and boswellia, and I've also drenched the soil of my other native plant starts. I've had zero issues with mold growth or damping off so far.
