    Sure you can! Most potting soils have fertilizer in them which will diminish over time with use, just fertilize your plants by other methods.

    HI Mary. Every spring I take all of the soil from my pots and mix in new, and then use that for my potting soil.

    Never! Old soil is depleted of all of its organic nutrients and is loaded with insoluble residues of minerals and chemicals various kinds that have collected throughout the growing season. Some come from liquid fertiler, most comes from the tap water used to supply moisture. Have you ever noticed strange looking crystals on the top of the soil or on the sides of the pots that looks like table salt? Those are insoluble bad stuff that plants can't use. Buy, or make, new and good potting soil for you potted plants. And, never use gardens soil or dirt from your yard. Only god knows what guck that stuff contains...lots of pollutants more than likely. Don't be cheap. Buy good quality potting soil from a reputable maker. Beware the stuff (cheapest) that is made from composted sludge (from a city sewer system) or manure. It is only good for use in outdoor flower beds when mixed with existing soil.
