The packing peanuts in the bottom is solid advice. Use the white or green ones, the other colors are treated with anti-static chemicals.
The watering advice is also good- you want to flush the medium every time you water. Trdyl is right, bark does not absorb water quickly. A good way to water is to allow the pot to soak in water for a few minutes- like in a clean bucket. Then flush with water to get any fertilizer buildup out.
Try to find a fertilizer that does not have Urea based Nitrogen. It should say what kind under the ingredients. Look for ammoniacal or nitrate based.
