| I am hearing a lot about Mel's mix i checked at Lowes and it is rather expensive. I have a 3X8 X 12" Ft elevated planter. can i fill it partially with a potting mix like miracle grow and then place a few inches of Mel's mix on top ? |

| If the potting mix already has a significant amount of vermiculite or some other moisture regulator / drainage component to it, you could get by with mixing some straight compost into the top portion to boost the nutritive organic component. |

| What is wrong with your native soil? Amend with compost and coffee grounds for a significant cost savings. I have done this both with sand and clay soils. |

| You can get away with 6-8" of depth (unless you want long carrots), Mel's mix is a well balanced combination and has been developed from much research, especially for shallow depths. Using some potting soil probably wouldn't hurt; I've done so without any problems. Depending on where you live, native soil is usually too heavy and nutrient-poor for SFG, but is always improved by adding plenty of compost and vermiculite. |
