Rated excellent for starting larger plants like vegetable vine crops and large growing annuals. Grow earlier, better vegetables and flowers by starting in Jiffy Pots. They encourage vigorous growth. When you transplant pot and plant into the garden, there is no checking or wilting, since the roots are not disturbed. With our 4" pots, they sustain growth longer for large, fast growing plants like squash or pumpkins. When you only want one or two of any one variety for your flower boxes or beds, we recommend Jiffy Pots. OMRI listed for organic use.
