Dracaena Problem

There could be one or more of several reasons why the leaves are spotting and the stem is rotting: make sure when watering (about once every 7-10 days) that the soil feels dry down to the first knuckle before watering again and that the water drains out without allowing the plant to sit in water (if there is a saucer under the plant and it is sitting in the water after watering, then this may lead to root or stem rot and leaf edge browning); feed with a slow-release or organic fertilizer formulated for container plants; the potting soil should be a well-draining commercial potting soil or cactus potting soil (sterile and well-draining); needs bright, indirect light-the spots may be due to leaf burn from too much direct sunlight. Finally, if the leaves continue to spot and discolor, suggest you switch to steam iron water – many houseplants come from the rainforest and are sensitive to the salts in tap water. There could also be some disease issues. Here is more info: http://www.hgtv.com/landscaping/qa-leaf-spots-on-dracaena/index.html
