Try to get your hands on some decent soil and be sure not to compress the dirt in the medium, let the water pack it as you water. The looser the soil, the better, allows more oxygen to get to the roots. When you water them, make sure some water starts to come out the bottom holes and do not water again until the top 3-5inces are dry. You have to make sure the bottom of the medium stays wet but not so wet is cause root problems.

Let me know if you have any other questions.

Good luck!!!!
