We've planted our fall crop of veggies and then we checked the ph of the soil. All the veggies grow best in pH of 5.5 - 7. Our soil is at 3.5 pH.
Since your garden is established, you need to add lime in increments rather than all at once. And it takes time for the change to take effect, especially since it would have to be surface applied and not worked in. I fear your current garden will suffer in the meantime. Is it possible to move the plants to a more desirable bed now? (If you only have a few vegetables, containers will work.) Then you can work on this bed up till the ground is frozen and get it ready for spring.

Hello, I am soooo excited, a couple of months ago I learned about the Mittleider Gardening method. I have their book and I'm ready to go, however, I have a question about the soil I should use. I live in South Florida and have been gardening in raised beds filled with organic potting soil. A couple of days go I filtered the soil using a screen (my husband made) to remove any rocks, debris, etc, and now I'm left with beautiful fine soil, like potting soil for my Mittleider boxes. My question: aside from the fertilizer that is recommended should I add anything to the soil, such as mulch, compost before planting? Thank you in advance for your help.
