Several weeks ago an inquiry was made as to what types of plants can be mixed together in an EarthBox. I indicated that I would try to put together a list, however that has not been possible because we seldom mix plants in our EarthBoxes. If we want to grow a different plant, we simply plant a new EarthBox. The general rule of thumb we tell people is if you want to mix plants, try to mix plant types which you would plant the same number of in an EarthBox. Even more importantly, if a plant is planted on the opposite side of the EarthBox from the fertilizer strip, as with tomatoes, melons, eggplant, and cukes, try to avoid mixing these plants with plants that are planted on both sides of the fertilizer.
Now, to address the development of a plant mixing list, I am turning to all of the forum members to contribute mixing success stories as well as mixing disasters (in the EarthBox only, of course). I am looking for contributions regarding what you have tried in past seasons, so that you know for sure if it worked or failed. If you're trying combinations for the first time this season, let us know about your success of failure when you're done with your harvest, please. Future plans may be to compile this into a single list for future reference.
Thanks in advance for your contributions
