Comments (7)JHC - For the sake of accuracy - the most common cause of spoiled foliage on dracaena and all other plants we so often discuss here is over-watering, often exacerbated by a high level of solubles (salts) in the soil, both of which regularly accompany the use of overly water-retentive soils. ALL fertilizers and ALL tap water carry with them the certainty that solubles will build up in the soil if poor watering habits are used - not just synthetic soluble ("chemical") fertilizers. 65-75* temperatures are ideal for most houseplants and are not the cause of spoiled foliage. Even though I allow water to rest overnight to come to room temperature before I water indoor plants, I have never found anything credible or anyone who should know (I'd asked a lot of people with plant related degrees) that would agree cold water 'shocks' plants. That I have always watered houseplants summering outdoors with cold water directly from the hose with no sign of problems supports the probability that the cold water thing is a myth, yet I still let irrigation water sit out night for plants over-wintering indoors - but NOT with the thought that it helps with chlorine/fluorine dissipation. Lol - I have no explanation for WHY I do this, other than habit, and perhaps because I'd rather have everything in place & ready to go when it's time to water instead of procrastinating. Hopefully, you'll find some value in this link that gives a basic overview that will help you avoid most of the things that bring people here seeking resolution to common problems. This link goes into a considerable amount of detail in outlining a concept that will help you get a feel for the fact that your choice of soil is extremely important in determining how easy/difficult it will be to get your plants to grow as close to their genetic potential as possible. Some soils are so limiting they make it extremely difficult, even for experienced growers, to obtain results that offer a satisfying return for the effort expended.

Comments (12)cathyandjim, when the plant was in the nursery it was being given ultimate care....in the environment there. You removed it to your home, to your dry air home where the plant now has to get used to its new environment. Plants react to changes in their usual conditions and your home is probably very dry because the furnace is on. Plants like their air to be more cooler than the usual home air temperatures. Do your plant a favour by giving it nighttime temperatures of 60 - 65º F. High temperatures during nighttimes causes exactly what your plant is suffering from...yellowing leaves. Watering it may cause the leaves to go brown due to overwatering. The nursery would have given the plant sufficient water during its stay there. Let the plant dry down somewhat between waterings and remember, its winter , the sun is very low and giving very poor light at this time. So it wont be requiring much water....the plant is not growing. Until the sun values return in mid February, don't do much watering, and definitely no fertilizer should be given. When you water, water always to drainage. You should see the draining in the saucer under the plant. Let the plant be fully drained then dump the excess. NEVER let the plant sit in that drainage for more than 10 or so minutes. Light at this time is low in intensity. Dracaena likes a bright light...but not a direct light. At this time, due to the lower values the plant can be put closer to the window...and drawn back somewhat as the sun returns. Only when it begins to grow should you fertilize with a 20/20/20 and do so at a reduced rate as the plant grows. The leaves may continue to brown as the conditions change for the better. Keep them clean and in good shape by cutting the brown with scissors. The brown will not turn back green so its best to keep the plant in its best looking....See MoreMy Janet Craig Draecana is turning black!
Comments (4)Seems to me that's a fungus on the plant originating from permanently wet and soggy and stagnant soil/potting medium - and that's a mould growing on the surface. If it was mine I'd get the plants out of there, wash away most of, if not all, the soil from the roots; wash and sterilise the inside of the pot and check to see if the drainage holes are clear and then repot with new, well drained potting mix. I'd also spray the plants with a fungicide, perhaps Triforine. When that's done, I'd stand the pot on something that allows the water to drain through, a couple of chocks like broken bricks or something. I wouldn't be surprised if there is also an offensive odour emanating from the pot....See MoreHelp! Janet Craig angry!
Comments (5)While the plant is sensitive to compounds that contain fluorine, it's probably not a good idea to assume that reducing or eliminating the amount of fluorine your plant is exposed to is going to solve your issue. There are 2 reasons not to make the assumption. One is, there's a very good probability that fluorine (or chloramine) isn't the issue. Fluorine toxicities usually cause a lot of chlorosis (yellow foliage). Second, if it IS the issue, the fact that fluorine toxicity is caused by the accumulative effect of compounds containing the element means it's already in plant tissues at toxic levels. Other possibilities include over-watering and/or a high level of dissolved solids (salts) in the soil solution. This plant is very sensitive to over-watering and over-fertilizing, or to not watering correctly, which leads to a high level of dissolved solids in the soil solution because you're not flushing them from the soil when you water.
