We suggest planting your newly purchased Spider Plants into a container 2-4 inches wider and 3-5 inches deeper than the container it is in currently. Use a well-draining potting mix, and be sure to disturb the roots when transplanting. We recommend adding a slow-release fertilizer to the new potting mix. The most common cause of plant death after transplanting is planting the new plant too deep. A good rule is that you should still see the soil the plant was grown in after back-filling the container. Keep in mind that this new potting mix will retain more moisture than the previous container, so watering, in the beginning, should be less frequent.
