Hi all. I am a newbie to DF. I got a cutting 3 years ago of unknown variety and finally I got a first flower last night. I have to say  it is just gorgeous !  I think that unfortunately it is self-sterile. What do you think?
 

Your plant looks like a white variety, possibly a light pink, based on the plant's thorn structure and the lack of any coloring in the flower. If you could add pictures of some of the older branches it might help narrow down the identification, although like other said, a specific named ID might not be possible without fruit.

Hi guys, I tried to plant dragon fruit and on the start I even didnt know if it will survive or not (living in Netherlands so keeping that on window most of the time).
In one moment it increase process of growing and from 5 small flowers get already full pot. But now I am facing with 5 problems (questions):
1. It seems that it "body" of flower drow very very fast and thin, previous body was thick. Not sure if its because low amount of sun or too much sun.
2. On some body parts I notice that they have regular shape, and in one point it seems very very thin and after that it is thick again, it seems like that it almost break how its thin. Not sure if its normal or its because of some issue.
3. I got some "body" skin issues, looks like some "dots"
4. I got some another "body" skin issue, looks like some white cover on skin or missing green pigment.
5. Is there something what can I do to improve life of my DragonFruit children?

Hi JirkaH. The thin growth is due to lack of sunlight. You mentioned flowers, but your plant is far too young to produce flowers. Iím not sure what the weather/season is like in the Netherlands, but sunlight is a dragonfruits best friend. Without enough sunlight, plant growth will be lacking and flowers wonít ever develop. Did you grow your plant from seed?
Skin issues are a standard problem with dragonfruit. They all get it occasionally, but lack of sunlight doesnít help with those problems unfortunately.
Sunlight and heat are the best things for healthy dragonfruit growth

Hi, thank you so much for your reply.
I grew this from seeds. Is this a reason why there are no flowers yet, or is it because its still young (approx 1year).
I noticed the dry part started appearing when the plant was exposed to too much sunlight. Which is why I remove it from direct sun for some time.
After your comment I put it back immediately.
How often do you recommend to water it? Its an indoor plant.
Do you also have any other recommendations regarding taking care (fertilizing, vitamins, antipests,...)

Thanks a lot.

A few pointers:
1. If youre going to keep the plant indoors forever, you need to think about upsizing the pot soon. To be reasonably successful, dragon fruit needs to have long drooping branches, to allow the plants natural chemistry build up in the downward hanging stalks. Youre probably going to need a solid platform to place the pot on, because to grow tall enough to have hanging branches you need to either have a post for the main stem(s) to grow up, or have the pot high enough in the air to allow branches to grow long enough straight out of the pot. If you have a dedicated window you can grow your plant in front of, the best answer might be to hang it, off SOLID chain from a ceiling rafter or other support. You'll probably have to keep it trimmed down once its mature, as these plants can weigh in the hundreds of pounds if left unmanicured. after that, you can use curtains of various transparency to moderate sunlight to your plants preference.
2. The damage looks fungal to me. Get a sharp, thin knife and sterilize it with rubbing alcohol and cut/scrape the dead sections off or out. You can either sacrifice the stem above the diseased sections or just cut away the bad, down to the central core of the branch. But dont cut the woody core. Think of that like the wood of a tree, and the green section as the bark. You can lose entire branches of the green plant material, but as long as the central core is unharmed, any plant material further down the line will continue growing. As for treating the fungus, I'd try an anti-fungal copper soap spray mix. Its worked pretty well for me in the past to keep my plants reasonably healthy during outbreaks.
3. Just out of curiosity, do you happen to know what type of dragonfruit you got the seeds from? I'd hate to see you go through all this trouble and years of waiting to find out you have a variety thats not self fertile and you'd have to either have to hunt down pollen from other people or have to grow a second plant from seeds/cuttings and have to wait all that time again.

Wow 133 pages and Iím spent! Lots of greats Info for a newbie like me. I just started growing dragon fruit. I presently have palora, frankies red, sugar dragon, bruni, and some unknown whites.

Thanks Mike T for your post #3113 it really cleared things up for me as I was getting all caught up in the hype of getting a million different types of dragon fruit. Hopefully I can cut out all the unnecessary collecting. Any suggestions on sweet fertile whites or are they not worth it in comparison to the red and purple flesh fruits?

Others Iím interested in getting are condor, delight, and American beauty. Iím just curious if these are good ones to get or any reason why I should pass on any one of them? Are there any must haves other then Sugar dragon? Also, stupid question but is Columbian red a specific cultivar of dragon fruit or simply any red type from Columbia?

Thanks 🙏🏻

Early on in this thread there was a brief mention of Leoís Costa Rican dragon fruit H. costaricensis X S. Megalanthus. It was red flesh and no thorns on the fruit. Is there any update on this one?

Wow this design is just amazing! but I guess you need special tools and a solder to make it; was it too expensive to make?


Aluminum is lighter than wood and concrete!! Or you just tig weld some aluminum and it's good for the next 2000 growing seasons and not having to fix wood or look at a failed design saves you money and ego. At least when we get a huge hurricane my d.f. posts will be there still 😆. 

I love growing tropical fruits in Almunecar, Southern Andalusia, I also deliver them to western Europe through my web www.tiendadefruta.com

Happy to help you if I can :)

My Dragonfruit won't quit growing UP...
« Reply #3308 on: October 11, 2021, 06:53:08 PM »
I planted this dragonfruit (our first) in our greenhouse about a year and a half ago. It grew up through our supports and just keeps corkscrewing around. It has split and branched, but isn't doing the hanging down thing we expected.

It's probably hard to tell from the photo but our trellis is a dead juniper trunk set into concrete. it has another juniper branch screwed to it to provide the "web" that we thought it would cascade over.

This summer a second shoot came out of the base plant and is climbing up as well.

What are we doing wrong?  Do we need to cut off all of the dead juniper branches that reach up beyond where we want the plant to bend over? (Can it somehow "see" that there is still something above it to reach up to?) At one point we put a screen "topper" over it to keep it from going up. but it just keeps twirling around and reaching down, out, and up again.

We do have shade cloth over our greenhouse to protect from the intensely harsh New Mexico sun... did we overdo it with that? Our cheapo light meter indicates light toward the high end of the scale but it says that's 1000-2000 Lux which doesn't make any sense because I found references saying plants need 10,000 Lux??

I've searched the forum and have found others suggesting cutting the main stem off at the top to encourage it to put out more branches and go down, but ours already split at that point -- I have a feeling if we cut it off all of the new growth would keep just going 'round and 'round...

(I don't know what type this is, we just ordered it from Fast Growing Trees as a "Dragonfruit" as the ignorant newbies that we are...)

Thanks in advance for any ideas!

Kimi,

I'm not sure which way the structure faces but looks like you are only receiving 1/2 day sun at that location? Maybe a bit more or less? That, as well as your other shade cloth is certainly not enough sun for your DF. You can tell by it's thin growth. At that age, the vine should have significantly more girth, regardless of variety. Your vine is "stretching" for the sun and is confused.

Once you get it in a location that has more sun, things will improve. You may want to cut the plant to take cuttings and try a different location. 

As for training, this kid has a great channel for his commercial operation that will provide value on some training and growing of the plants:

Thank you, John!

Our greenhouse faces south and gets sun all day, so that's not it.

But I have been suspecting the shade cloth... we went with recommendations from other local farmers since we are new in this area. They shade their tomatoes here because our sun is so intense it will fry everything. I think we need to go with a less dense shade cloth.  But at 90' x 14' it's an expensive proposition to muck around with by trial and error!  Maybe we should get a smaller piece of lighter shade cloth and try that on one section to see how it goes. Our cherry tomatoes are going great guns, but not much else is...

Try a 30% shade cloth. Some varieties that I grew under full sun were: Haley's Comet, Physical Graffiti, and S8.
