A while back ago I posted a thread on here about a dendrobium I received and the leaves turning a spotted yellow and then completely yellowing. Well I received a replacement plant for it since it's roots were in pretty bad shape when it arrived, very dehydrated. I figured that was what my problem was with the leaves. Well the replacement plant had somewhat better roots...but not by far. I put it into a container with sphag moss and it seemed to be happy...the leaves were a nice green (a little on the dark side) and very firm. I think I have had the replacement plant for about a month and a half to two months now and all of a sudden it is having the same leaf yellowing problem. The yellowing starts with the bottom leaves and works it way up and only one or two yellowing at a time. I have tried trimming the leaves off at an early point of this happening and it doesn't seem to help. Sometimes the leaf will look like it has leaf rot...but I KNOW I am not getting water on the leaves when watering. I figured that the first one was just pouting on me....but it dropped all of it's leaves...I still have it and it has one cane that is turning a brownish color now, I thought I would see if it would come back. Now I am affraid that this replacement plant is going to loose all of it's leaves as well. I don't have this problem with all of my den's....just this one so far and I don't get it! I have a different den in moss as well which is rebuilding it's root system (another from the same seller) and it is putting out new growth! Any idea's of what is going on? I keep it moist but not soggy and the plant is in a west facing window that gets full sun off and on through the late part of the day as the sun shines through the tree's in the backyard, so I know it isn't sun burn. Any help is appreciated, I may not respond to messages until Monday since I will be leaving for the weekend tonight. Thanks!
P.S....wow that was a long one! oh and the den is a Burana Emerald
