    Default Rescued Dendrobium-Help!

    Last post, (I'm new to this and can't keep track of my messages) Friend had dendrobium in a bowl of water in a cool hallway. I immediately cut dead canes, transplanted into smaller pot, fresh medium. New shoot, roots dry, thin white. Place on tray of pebbles. One leave died on other cane, cane still green.

    My question, the current shoot looks like it's turning a bit yellow with a tiny speck of brown at tip. What is going on? What can I do to prevent losing another leaf? Does it need to be fed? Temp too cool? Lack of light?

    I'll be waiting to read the replies to this as well. I have a dendrobium I, too am nursing along. Good luck. I'm sure you will learn all you need to save your orchid!

    Some dendros are deciduous and leaves turn yellow and fall. Others tend to drop lower leaves as normal. The cane remaining may flower one or more times depending on type. Leaves can also turn y on dendros due to shock, cold draughts. watering too little too much, or phytotoxicity to chemicals for example pesticides and overfeeding and over use of products like neem oil or superthrive.. Do you see healthy root growth are their root rot issues? Post a pic as its difficult to narrow the possibilities down to a diagnosis. Watch salt build up if you use ferts. Flush pot at organised intervals to rinse medium with plain water.

    I have tropical fish tanks, I water my plants with the water I take out of tank. Lots of fish emulsion! Apartment is cool. Roots are dry, white and shriveled. I have pics on digital camera, don't know how to download them.

    I had it in a bathroom of a trailer, with frosted glass. The little bugger bloomed three times! Now it's sick and I don't want to lose it.

    Click on the attachment icon (above) Locate your photo 'browse' (from where it is stored) and click to insert. Failing that one of the moderators will email you how to download a photo.

    The leaf is getting more yellow, should I fertilize the plant? I moved it away from window, afraid of it getting cold.

    I shouldnt worry too much over the changes to your plant, dendros and plants in general shed leaves. Dendros and most orchids are tough survivors. For some reason natural or not the plant has decided too abort the leaf/ves, the yellowing purely signifies that its cells have been shut down and chlorophyll no longer utilized by the leaf for photosynthesis ( process of making food and energy with the sun). Cut it off. It may well be acclimatising to its position. The sudden short days and cold night temps that are occuring here due to season change have triggered changes all over the plant kingdom. Many of my orchids in the catasetinae family inside with a night room temp of 19-20oc have yellowed and dropped leaves.

    Many dendros exist with bare canes. Some with leaves and some without. Only new grwth canes will have priority from the plant. Dont cut bare canes as these can re bloom or produce keikis (baby plants). I always cut yellowing leaves off cos they are unsightly.

    Allow your dendro to rest now. No fertilizer for Nov, Dec, Jan

    Hope you get to figure out the upload pic thing soon. Read the guide. Brutal Dreamer has posted troubleshooting /faq guides to help out.

    until you crack the upload photo task and you feel you need to do something constructive to ease your concern try process of elimination. As your dendro has been relocated within your apartment it may have responded to the change with a temporary sulk. Yes! orchids sulk like a spoilt child not getting their way.

    Although the net is ideal for research try not to fall victim to 'fear mongering', deluded and ignorant people who confuse opinion with fact and clever marketing to advertise products.

    Now that your dendro should enter a rest period take advantage of the opportunity. A cool dryer rest encourages bloom.

    Step 1. assess your watering - tank water is fine but be aware of bad pathogens introduced to your orchid. Symptoms of underwatering can cause leaves to yellow. Carefully check media inside of pot.
    - If the bark is dark and overly wet you may have root rot (overwatered) therefore the plant cannot drink thus moisture deprived.

    - If yes change media, remove rotted roots and repot. Rest periods are supposed to be dryer. Reduce watering and allow to dry between watering again when in growth mode spring onwards. Mist leaves underside included. New growths will produce new roots in new season or when it chooses to.
    - On the other hand if bark is bone dry throughout, the roots would dehydrate, shrivel and die. The plant basically lives of its reserves which can be exhausted after too long. Look up 'sphag and bag' technique for your future reference.

    allow your plant to stay in a permanent location within your apartment as changes in temps, light availability shocks the plant into sulk mode. Place in situ and let it rest. Will wait and see what you concluded so far.

    Thanks ladies. I found another light purple orchid ----vendor information removed - see faqs on posting ----. I'm up to three, this is addicting, LOL. Will have to research to see what it is. As for water from fish tank, I let the poo settle to the bottom of a milk jug before watering orchid. I live in town, so we have chlorinated water. I fished out my humidifier and plan on turning that on. Potting medium is brand new and I planted it in a smaller clay pot. I've noticed in photographs that orchids have their roots coming out of pots, is that not a sign to transplant?

    When I made paper I had a real problem with some colors because of the chlorine in the tap water causing the color to fade even before it was able to bond to the paper fiber. I solved this by filling the papermaking tub, a 25 gallon tank, and letting it sit for 24 hours. The chlorine off-gassed during this time. You can also buy distilled water for your orchids. I use tap water which is chlorinated and so far have had no problems.

    Bruce has a really good photo uploading video tutorial that is easy to follow. OrchidTalk Orchid Forum At the bottom look for Edit 7-4-2010 for the link for uploading images directly from your computer. If I can do it, anyone can. Good luck - martha
