Epiweb and Beneficial Microbes?

[AlexS]

Hi,

As mentioned in another post I grow a number of Dendrobium in clay pots with Epiweb substrate. Recently, during repotting I noticed that two of my plants are showing signs of root rot, nothing too worrying at the moment, but I want to get on top of it as quickly as possible. I'm considering using a biological control, Trichoderma and a bacterial inoculate of some description, but am uncertain as to how effective these would be in Epiweb. I tend to grow my Dendrobiums on the dry side, and although I'm watering every 4-5 days in the summer heat, it's usually only once a week, or every 10-14 days during the winter rest. Would this be too dry to allow microbial products to work effectively? Can microbes survive long term in Epiweb? Does anyone have any experience using products like these in conjunction with Epiweb?

Thanks in advance for any advice.
Kindest regards,
Alex
