Wait for the seed to sprout, which may take a couple weeks. Be warned: the paper towel may look disgusting. If you planted one and the bag is moldy, throw it out. If you planted two and the whole thing is moldy, throw it out; but if you planted two and only half is moldy, don't throw it out. After it has sprouted, take it out of the bag and plant it in good soil. Be careful not to disturb the roots. Be sure to give it full sunlight and lots of water
