I searched through the old threads on how to make a cactus pad grow. But still a little confused, The pads I received from the Tortoise Supply (ordered 4lbs wow gotta lot of cactus now and it was fairly priced) have already been scarred per say so do I need to cut the pad again and put it in the organic poting soil or do I just take the pad and plant it 1/4 way in the soil and leave it alone for a month. Then start watering it once a month after?? How will I know if its actually rooting?
