Earthbox soil type potting mix for best growth of vegetables

pectinMarch 24, 2011

I have a few choices to make. Use ProMix BX or FarFard Organic or Happy Frog� Potting Soil or Happy Frog Ocean soil. Prices are not much different. In the Promix I will probably have to add vermuculite and possibly some perlite + Dolomite lime and 10-10-10 fertilizers. They will be used in Earthboxes. Some tomatoes, okra, eggplant and other vegetables. For PromixBS I have to add vermuculite, perlite, dolotmite and fertilizier.. but the others I might not have to do so. Do I need to add vermuculite, perlite into the Happy Frog and Farfard potting soil as well. I was told you did not have to. Please advise. The fertilizer and soil are all according to Earthbox recommened media from their site. Why follow? As in the past I had done things like adding just regular topsoil... it did not do so well... got a lot of BSR on tomatoes but okra did well.. Thanks

which is then the best?

I think they'll all stay more than moist enough without the addition of vermiculite.

But I don't have any recommendation otherwise.

I prefer Pro-mix but it's a preference thing. Something with good drainage and aeration.

I'd choose Promix, and I wouldn't add anything to it but fertilizer. The other mixes could cause problems with moisture retention in an Earth Box because of the organic additions. And they are unreliable nutrient sources in any container, so you'd still need to fertilize.
