Mine is much younger, but I'm surprised to see yours isn't further along then it is. Mine is at nearly the same stage and I'm in a much colder climate (winter wise).

It may be the way you put the tree (direction, hours of sunlight).

I had to prune off guava and jujube trees this morning to get more sun light for bonsai which are beneath or around them. While working, I spotted this Erin dragon pot. It is one of my favorite pots. The dragon is wrapping itself around the pot.


Then I found a baby cork elm!

Spoken like a true hoarder. @namnhi Is this a Vietnamese thing? I have this same issue.

This giant pomegranate cutting is ready showing the life in the end of the winter.

Another big pomegranate cutting also has life back.

I still keeps them in the plastic bags few more weeks. They will be my big project in the next few years. I can not wait!

Those are cool looking pomegranates. Do you do a lot of the lifting yourself?

hahaha! Your question is your answer!

No. I ask my BFF to help me out https://bonsainut.com/threads/how-can-you-handle-the-large-bonsai.3067/page-3

When the jujube tree starts waking in my garden, it means the Spring arrives!
It is very accurate sign!


This crabapple tree is in half- full bloom at this time.

[bonhe]

Because Spring is coming, it is good time to remove the plastic bags from pomegranate cuttings.

It has a lot of new shoots!


You will see in those cuttings, a lot of new shoots emerge from the cut surfaces. Why is that? I think I asked this one time, but I did not get any answer!

The trunk base of the above cutting.


Another cutting.


Another one.


There is a cavity (yellow arrow) communicated from outside into the inside of the hollow trunk
in its mid trunk. It will be very fun to work on this one in the future.

Every one knows the sunlight exposed duration will affect to the dormancy.
These 2 crepe myrtle are in the same location but sun exposure is slightly different.
This one already received about 30 min sunlight daily. It is awake now.


This one is not yet received sunlight. It is still sleeping.


I love the bright red of JM in spring.


The leaves are not fully open yet.

Tamarix this morning. I can not wait for blooming time!

Spring is already here. Lots of pine pollen from neighbor's yard landed on my trees!

After dust them off.


This BRT has been shedding its leaves after transplant on 2/20/17


However, its vegetative buds are swelling up at this time (arrows)

It seems that they sprout from the cut cambium layer like elms do.

Yes, you have very sharp eyes!


Learning point?

[0soyoung]

Learning point?

Growth comes from cambium.
Cambium cells are (literally ) stem cells - they can become anything (wood, bark, roots, shoots).
Excess auxin --> cambium cell can become a root apical meristem (e.g., make a layer, root a cutting)
Excess cytokinin --> cambium cell can become a shoot apical meristem (e.g., those crazy pomegranates!)

Horse chestnut is really good at this, like pomegranate is.
However, horse chestnut has few other interesting characteristics.

 

[bonhe]

I agree with Osoyoung.
Now one should know how to get a new branch in wherever part in the trunk or branch .



This afternoon I pruned 2 big hibiscus back.
The 1st one: before and after.


The 2nd one: before and after

Hello, Bonhe!
Will you kindly let me put my question at your thread......

... ...If you remember my post "Inverted cutting", this is a reason why we can do this method for some of species.
The humidity is so good for the roots appear in the air!

It's been 20 days now that I have removed one Ficus carica which was growing out of a tiny crevice on a wall. I just cut flat with a saw and the stump's diameter is about 6-8cm, good tapering and the trunk has a cascading movement. After planting the stump, the pot has been put into a clear plastic bag and misted every now and then to preserve moisture. What I've got until now is a lot of roots all over the lower part of the trunk and around the cut perimeter as well. I check every now and then using a magnifier glass but not a sign of a dormant leaf bud starting to swell.
Would you kindly share your opinion? It will be greatly appreciated!

S0rry, a little dump up here (as foghorn leghorn would say). How do I get the F. carica to develop new shoots?

 

[0soyoung]

How do I get the F. carica to develop new shoots?

Usually, just by pruning.

The apical meristem or branch tip is the primary producer of auxin; foliage is the secondary source (and then axillary buds). So, decapitating a branch or 'cutting it back' (as we say) causes the auxin flow to drop (below the cut) and makes for new shoots. Cytokinins are made in the root tips and are transported up the tree thought the xylem (wood) in the transpiration flow - this background level is difficult for us to manipulate and varies with the seasons.

With a stem segment cutting, the cytokinin level is set by what was in the xylem at the time it was cut. Good nitrogen fertilization and harvesting during the growing season would provide a high cytokinin level. If the cambium cells were in a tissue culture you could add cytokinin to induce shoot meristems, but with a cutting, you are stuck with the levels the species normally produces, which may be inadequate.

... not very helpful, I know.
