The Tropical Fruit Forum

I had several yellowing ones on both plants, removed them as soon as i was sertain they were to be aborted.
Well, i am not that fussy about fruit size, i would be happy with big fruits, but i woudnt remove some of them as to have a few bigger ones. Its hard enought to grow them here, dont want to be that picky...

My family is spoiled.  They won't eat small fruits, lol.

dark fruit. Fruits are big, dark, and sweet (when it is really ripe) with high acidity.    Not much gasoline smell.

Red fruit. It was grafted last year.  Fruits are even bigger, red, and sweet.  Not much gasoline smell.

Is your red fruit a named variety? Where did you find it?  That’s a good looking fruit. Nice size.

Unknown variety. I got it from exchanging java plum plant for cutting.  The ripe ones are just sweet , a lot of flesh, and jucy.  It is the size of a cherry.

Plantinyum, why growing this variety?  For me, I thought because it is sweet.   I abondoned it because the fruits were too small, not that much sweeter than American Beauty, and the stemps are too thorny.

That looks like a bark graft to me.

Hard to tell from the picture.  I used to have it.  The stemp is darker green, thicker, and smaller than other dragon fruit stemps.  It just look different compare side by side to others.

Simon, I'm good.  Thanks.

Nice.

I have brewster, mauritius, and hak ip.  I did not water enough, and the flowers drops almost all.  Will do better next year.

I plan to plant more of them.

If it is sour and the tree is full of long thorns, then it is kei apple.

Thanks.


Where do you obtain the rootstock?  I'm in san diego.

Good job.  I think I have the same small round fruits variety as you.  I hand pollinate it as well.  So far, less fruits than you.  On hot sunny day, the pollen is ready around 3pm.  At 8 pm, it the pollen is less potent, from my observation.

I also has another bigger, and longer fruits variety.  The flowers have about 4 times more.  The pollen is ready around 1pm.  I use these flowers to pollenate the round fruit variety.

The flowers that drops,imo, has to do with how potent the pollen is; that is, how fresh the pollens are.  So when to pollenate is cruicial.

If your tree is over produced, the flowers will not drop.  Usually, the fruits will be smaller or drop later on.

sounds interesting, how long does it take for the calus to form enough to try the graft?

It might work but the graft union will probably come out fat and ugly. I hope it would heal like a normal graft.

I would be interested in hearing and seeing photos of your results.

I will try this approach this year.  Will update the result afterward.

Some plants are tough to graft. Guava is one of them. Currently, approached grafting seems to be the most successful; however, it is tough and time comsuming to setup.

So I'm thinking what if we graft by calus instead of cambium? Note that I have not tried them out yet.  Let me know what you think.  Here are the steps.

1-cause wound on both scion and rootstock by peeling off a strip of bark. Note: do not cut off scion or top work the rootstock.

2-Let the scion and rootstock try to heal the wound by forming calus at the edge of the wound.

3-Once there is enough calus formed on the scion and rootstock, do these:
a- remove the scion by cutting off below the wound. Wrap it with parafilm.
b- top work the rootstock by cutting off above the wound.
c- gently scrap (not remove) the calus on both the scion and rootstock.
d- attach the scion and rootstock, making sure their calus are contacting.
e- wrap the joint.
f- Shade the scion with a piece of leave, paper, or aluminum foil.

I got caught once by the agency.  Being very cautious now.  Thanks.
