Dendrobium Seed Pods

11 years ago

Believe me, I do not have a green thumb for orchids. I got the original in 2004 when the plant was very small. It lived in a 4" pot and was left unattended for several years. I finally rescued and attached it to a coconut tree stump for several months until it grew. Then sliced off a portion of the stump it attached to and wired the whole thing to a living tree trunk. There it flourished, flowered, and multiplied over many years. Then last August, the plant was detached and placed in a basket of coconut husks and moved to its present location.


During our rainy season, over a dozen flower spikes were produced--many of the canes produced two spikes at a time. (Wish I had taken pictures then.) And since then, new sprouts from the base appeared and keiki's are also growing on some canes.

Over the last two months, however, no new flower spikes appeared on the mature canes. Questions:

  1. Should the older canes be cut off if they no longer produce spikes?

  2. Will allowing seed pods to mature cause the canes to stop producing spikes?

  3. Should the canes be cut off when pods mature?

  4. Is there a regular regimen for fertilizing?

  5. Is there a cycle to flowering?

  6. Will this Dendrobium flourish again during next rainy season?

  7. Am I paying too much attention to it?

Please help. I do not want to become addicted to orchids--already have Adenium addiction--just want to maintain this one orchid.

Thank you.

    -bong, Questions 1-4 answer:no Questions 5-7 answer: yes.

    Now, you don't say, but your photo says you probably have a Dendrobium Phalaenopsis. so, do not cut off old canes until they are dried up and near dead. They retain nutrients and water that the rest of the plant uses as needed. Once bloomed out old canes will not bloom again.

    Production of seed pods does not stop the cane from spiking. Pods form after mature flowers are pollinated, meaning the can has already produced its flowers and it won't produce any more new spikes. Seed pods do draw nutrients from the plant, and unless you intend to sow the seed, I would just break them off and discard them. Seed sowing is another entire story, that you surely don't want to get into.

    3, see first paragraph. do not cut old canes until dead.

    4. The regimen to fertilizer is if new canes are growing, fertilize probably 30-10-10 or something similar with high nitrogen. As the canes mature cut back on the nitrogen, or just cut off all fertilizer until new growth starts. If its growing, feed it...if not, don't, or at least only lightly.

    1. Flowers only form on new mature canes, usually fallish. Cut the bloom spikes after all blooms have dropped off, but old canes don't bloom again.

    2. New growth will begin fairly soon after blooming. New growths come from the base of old canes. Keikis can form most any time...when they get a few inches long and have multiple roots, just break them off and start new plants, or leave them on the old plant and let them bloom there.....Mucho blooms.

    3. Yep, you are probably paying too much attention to it...don't we all? Your plant looks like its perfectly happy where it is, so I would not change a thing. Enjoy.

    Whew! Thank you so much, Bill, for your guidance. Everything you said makes perfect sense. And yes, I absolutely do not want to get into seed-sowing.

    Again, thanks a million!

    Good answers Bill. I think continuous feeding might be ok as this is tropical with non stop growth. Zone 11b Where are you? Happy plants!

    4. I add stuff to the fertilizer. I mix in maxi-crop. Norwegian seaweed juice. A root stimulator. Good for all plants as well as orchids. A new idea that the orchids like. I tablespoon to the gallon, black strap molasses. They perk up. I think it is because it gives trace elements. Heat the spoonful in a cup of hot water and stir then add in. All plants like that too. add to soil...Must be blackstrap. I fertilize full strength every 2 weeks. There are many different answers that provide great success. We each find our way.

    Thank you, Harvey, for your response. I am at 13.4 N,, 144.7 E.

    Because I have a knack for killing plants when I pay too much attention, I will keep it simple.

    Is that Hawaii?

    Harvey, not Hawaii. Check out Google Earth.

    Hey, Jairo, thanks for responding to my request so quickly. Yes, KISS. See you sometime in Adenium forum.

    Bilabongbong sounds a bit like Bong Bong or Billabong or Wollongong but you are in Guam.

    Amazing that I can get these sort of co-ordinates just by getting on the net.

    I am at 33.57 S,, 151.6 E

    And the arid westerly wind is blowing.

    Bingo. Guam USA. And you are in Sydney, Australia, right below us. Did you get any of tropical storm Pam's effects? We had storm Bavi go right over us at the same time, but thankfully, no damages.

    The made up name is a term of endearment for King, my pitbull-mastiff dog.

    Glad to meet you.

    You don't have to actually "get into seed sowing", but if you leave the pods there's a chance they'll self sow. Happens sometimes around here (12.6S). Looks like you have them in a mango, they have suitable bark.

    Thanks, and just in time too--I was just about to remove the pods. I'll leave them alone for now and see what happens.

    The seeds will become windbourne in time for your wet season. It may take a little while for the seedlings to become noticeable.
