What is biochar?

Biochar is an organic compound made from carbon and ashes that is created from the combustion of biomass in an oxygen-limited environment. In simple terms, it is plant material that has been burned in a limited-oxygen environment, similar to charcoal.

When included in Frank's Soilless Mix, biochar encourages nutrient uptake, buffers the pH level of the mix, reduces salt build-up, and improves microbial activity.

While both types of Frank's Soilless Mix are great for your citrus tree, the addition of biochar will make your tree more efficient with absorbing nutrients (so fertilizing is needed less frequently), and it is especially useful if your tree is experiencing issues with the pH level of its soil.

  • Too busy to talk on the phone (or are you a Millennial/Gen Z who hates phone calls)?

    Hey, we get it. 90% of phone calls these days are spam. If we have to call you back, you might not know it's us, so we'd play phone tag for three days before you'd get an answer for your question.

  • Use that internet brick - it's still a phone, right?

    We can be reached at 608-318-3744. We run our business out of our home, so we really don't have established hours for Frank's Fruit Trees. So...just be aware we may not answer the phone at 1am.

  • Head over to social media

    We have Facebook and Instagram and are happy to answer questions there too.

    And yes, there is only a link to Facebook. They're both the same thing anyway.
