Other aid. Need-based financial aid may be adjusted if you subsequently receive additional aid (scholarships, grants or loans). Private scholarship awards may reduce Board of Governors equity awards, loan eligibility or other aid.
Ways to Reuse Potting Soil. The easiest way to reuse old potting mix? Simply remove old plants from their containers, fluff up the soil and replant. If you've reused the same soil for several years or it's developed a white surface crust, you may have to cut it with 50 percent new potting soil and/or apply fertilizer.
When Not To Use. Eventually every potting soil breaks down into very fine particles which compact and does not allow good drainage. At this point, replace the potting soil totally. Also replace it if you find any mold or insects in it, This is also true for unused soils left over from previous growing seasons.
