Hi

I bought a one-year old red dragonfruit (white meat) seedling which was poorly grown with very weak stems. Now it has started new growth in the new clay pot.

My intention is to graft the yellow dragonfruit on top of it. The yellow seedlings will be ready in about a month.

My question is whether or not the slim stem of the red dragonfruit get thicker since it is under better growing conditions? Thank You! I'm all ears!

The new growth will be thicker but I doubt the old growth will change. You are growing a Dragon Fruit in a pot? Blinking

I think that's the only option in zone 5. For what it's worth, mine is still kicking in a pot after at least a decade, and it flowers profusely each year. Smiling

I would not graft anything on top of etiolated growth, which will not ever reach normal width and strength.

I would be curious to see your plants if you can share a photo.

Daisy and Baja, you both are right. Except for me, either I try or I'll never know. Big Grin

In Toronto Allan Gardens, a city owned Victorian palm house, the dragonfruit plant produced some fruit last year after their technician pollinated the flowers.

I will be happy with the flowers on a potted plant, even without any fruit. It's said that the yellow dragonfruit has very fragrant flowers. The white-flesh dragonfruit plant is said to be easier to grow, hence the grating idea.

I will take some photos tomorrow. Smiling

Here is the red-skinned dragonfruit in active growth. I may keep this one as the pollinator for the yellow one.

The yellow seedling will be grafted on top of this one.

Charlinex said:As a practice, today I grafted a Portulacaria afra variegata on a common jade plant.

Are they compatible? Don't know if it is working, at least I have tried.


I would guess not (they are from different families) but I am curious to hear how your experiment works out.

Baja, I know what you mean. Sticking tongue out

I actually planned and still plan to graft the variegated one on top of the green afra. Since my green afra is not big enough yet, I thought I would give the jade a try. Will let you know. Hurray!

The best kind of experiment is when you try something that shouldn't work and it ends up working anyway.

The yellow seedling has been grafted on common white flesh dragon fruit today. Big Grin

Now the yellow dragonfruit seedling is growing. The red color at the tip is an indication of new growth.

Another update, the yellow seedling has started to make side growths.

This is a comparison of my yellow dragonfruit seedlings, of the same age, being grafted and on its own roots.

My second graft was done about two weeks later. The growth has not been as vigorous. It may need more time.

Here is another update.

First, Daisy was right, the old weak stem won't change its original thickness.

However, it is still worth it to graft a seedling even on a weak root stock.

This photo shows the plant grafted on May 24 (left), June 3 (right), and the same batch of seedlings on their own roots in the small green pot in the middle.

By the way, the initial graft on May 19 was knocked off, probably by a bird.

The biggest growth was my second attempt. It's amazing how much it has gown in over one month. Sorry for the wrong focus point in the photo.
