Problem With Dieffenbachia

Is this the same dieffenbachia you submitted before? If so, and you followed the advice we gave previously, carefully inspect the leaves for insects or webbing. We think this is a cultural problem, but it doesn’t hurt to check. Be sure to only water from below and if the leaves appear to need that humidity sit is on a try of pebbles with water in it. Also if there is any salt built up in the soil (you can see this laying on the top) run water through the plant so you can wash most of that away. The last thing is there are one or two products on the market for indoor plants that is a systemic and will help to control any diseases or pests that may be getting in the soil. Oh, one last thought when was it last repotted? At this point it may not hurt to have some new and healthier soil around it. Any good potting medium that is well drained should work. It is hard to find but we don’t recommend potting soils with fertilizers in them but if that is all you can find use it. Guess that covers it for now but always know you can check with a local garden center (not a box store) if they sell indoor plants or your local cooperative extension agent has access to people who know all things plants! Good luck.
