The ones in the first pic are ripe like that.  Seems to be s. purpurea, jocote.

Try some more, some suckers have roots to start.  Not everyone works.

Sucker removal in Indonesia is routine from what I understand.
We have removed plenty but it is a chore.  We select a low growing sucker and prepare a pot by making a slit on one side and slipping it on to the sucker, then fill the pot with medium.  With a pruning saw I cut half way through the connection of the sucker to the mother plant.  After 3-4 weeks I cut half way through the remainder and again until the sucker has rooted and separates easily.

Hi Doug,
Frequently people figure they don’t have any females because the males flower first.  Hang in there.

I don’t know about sandy loam. Vanilla wants lots of organic material. I don’t think it needs any sand at all.

We also have pulusan right now along with durian, rambutan, marang, Langsat, Kepel, etc.  It is our secondary season, something that doesn’t happen on the Pacific coast of CR.  Some of this guys have been driving 6-7 hours to come here for durian!

No, fruits only on the dwarf mulchi.

Looks real good.  I’d go with a bigger pot, I think.  Or certainly in the ground if climate permits.

There are red colored pods among trinitario and forestero as well.  True criollo is very difficult to find.
Peter

Looks good is that a named selection?
Do you process it?
Saludos, Peter

That photo doesn’t look like champedek to me.

A lot of people use ‘mm’ or a homemade microorganism ferment. It can work well, depending. It’s kind of like making wine. If you don’t have a lot of controls you will get varied results. A friend of mine, we’ll aware of that, analyses his mm with a microscope to see what’s there. Most don’t do that. We buy the stuff

Unfortunately you can’t see the bottom of this tree in the photo but it is about 20’ tall.  It has been, as you can see, frequently topped at about 5’ below the top height.  That is at about 15’.
I think that breaking the tips at 18” is probably a good idea but keeping in mind not to let the shape get too crowded with small branches.  This tree needs work but at least there’s plenty of fruit.
