Achachairu or pulasan?

[bangkok]

I have pulasan but unknown variety and i have achacha-seeds. I have one great big spot in full sun and one smaller spot in 5 hours sun a day.

Which tree grows the largest? Which tree deserves the best spot in full sun and gives the best fruits?? I have never seen those fruits in real so i hope somebody can advice me.

And does any of these have destructive roots?

I hope the pulasan is grafted and you haven't rolled the dice on a seedling.Pulasans get big but are less productive I would think.Pulasan is sweeter but much like rambutan.Pulasan might need more sun but will bear sooner I suspect.The root systems of both are not outrageously destructive compared to many fruit trees.The tiara could go to either in this pageant.

Yes it is a grafted pulasan and a purple one as well but not sure if it is seebabat. Well i will prune them anyway if they get to large, or if my neighbour likes to eat them he can have the overhanging branches.

Well then i don't move the pulasan.  Now i have petch pakchong, namdocmai, avocado, pulasan, durian, achacha all in the small frontgarden.

At least the petch and avo will fruit at different times from the others but you might have a big pulse of fruit in early summer and then nothing.

I see, maybe then after the summer i can eat jackfruit, passionfruit, pomelo, orange, soursop, eugenia involucrata, lemon drop mangosteen or some of the seeds you sent me. Haha i even can't name all the fruits i grow without looking in the garden and have many big pots empty now.

I read that pulasan in Malaysia fruits 2 times a year, i hope my tree will also do that.

Is it wise to add some sulfur into the soil around the durian and the achacha? They both like ph between 6 and 7 but i allready added dolomite.

Depends on which area you are in Malaysia.In the west coast of the Peninsula it's common for rambutan,durian and pulasan to bear fruit twice a year.The reason for this is due to the rainfall pattern something like a micro-climate
