Nancy & Jeff had a provocative blog posting last week over at the Gardening and Yardening. They were questioning why, in this age of recycling, it is still recommended that you dump your container potting soil and start fresh each year. They offered recommendations for mixing in some fresh soil and some time released fertilizer, rather than wasting all the old potting soil or simply tossing it into your compost. (They like Dynamite Controlled-Release Fertilizer.)
What about you? Do you reuse your potting soil or dump it all and start fresh? If you have any tips for us for freshening potting soil, let us know in the 'comments' below.
