Potting soil in the ground


I bought some boxwoods this weekend and then discovered I was out of compost for the clay area where I was putting them. I had way too much Miracle-Gro potting mix, though, so I mixed that in the clay instead. Will that work in the ground? - Cindy -

    Potting mixes are designed for pots and do not work well in the ground because of the moisture beads and plants don’t adapt to the natural soil when they are in a potting mix. Since it is mixed in, it may not be as great a problem. However, boxwoods do not require a lot of fertilizer so the fertilizer in the potting soil may not be helpful to the plant. Since you have already done this, watch the plant carefully and don’t overwater. Do not fertilize as fertilizer may damage the root system in the first year. JOCOEMG

    I would offer this counter. Consider any of the moisture beads as a bonus with a very short-term life before they breakdown. The potting mix is mostly ground peat moss and bark which will breakdown into compost. So no problem using the potting mix in this way. I do it all the time when getting rid of old potting soil.
    Organic matter is a good thing so just consider the potting mix a high grade compost.
