Can the RE-250 & FP-60 be mixed with fertilisers?

Yes, as the RE-250 and FP-60 bacteria are stable you can mix with liquid fertiliser. The rule of thumb is if the fertiliser will not damage the plant's root system or foliage, it will not harm the microbial population. We recommend using the RE-250 and Biotic booster together to get the benefit of the bacteria and organic fertiliser as they work symbiotically. Studies have shown that there have been increases in plant productivity when both microbes and organic matter have been used.
