Intervale Potting Soil Problems?
Anyone have problems with Intervale Potting Soil? I transplanted eggplant, crucifers and pepper seedlings into this soil on exactly the same date. Fortunately, I also transplanted some into another potting mix. All of the Intervale potted seedlings became stunted. They developed a purplish cast (P deficiency?) on the lower leaves and the seed leaves yellowed prematurely. The other seedlings are now 3X the size of the Intervale ones. I fertilized with fish/kelp emulsion to no avail. The seedlings were all planted in 4 inch cow pots and received the same amount of light. I plan to contact the company about this. Any thoughts? BTW, Interval soil contains the following: sphagnum peat moss, perlite, aged pine bark, and organic nutrients such as blood meal, alfalfa meal, kelp meal, Actino-IronÃÂ®, ferrous sulphate, rock phosphate, green sand, and gypsum.
