OLD POTTING SOIL & MIX

OLD POTTING SOIL & MIX
Posted by RANDALL J. HILBURN from GEORGIA on 2006-07-19 04:33:00

IS IT WISE TO USE OLD POTTING SOIL THAT HAS BEEN SITTING IN A POT FOR A YEAR OR TWO .. COULD YOU RECYCLE IT WITH FRESH POTTING SOIL MAYBE A 2/3 TO 1/3 MIX ?? AND OF COURSE IT WOULD NEED A GOOD FEEDING & WATERING OVER A WEEK OR SO .... ANY INFO WOULD BE GREAT ,, RANDALL ...

    Randall,

    Most sources recommend not reusing potting soil. The concern is that any soil-borne diseases may be transmitted to your new plant. However, in my experience, this risk is pretty minimal.

    It is more important that the quality of the potting mix is appropriate for the plants that you are using it with.

    It may or may not need fertilizing as the soil nutrients have not deteriorated or degraded while it has remained unused.

    Let me know if this is unclear.
