Hello Bananalovers:

I am a German citizen with a Filipina wife who just built a house in the Philippines on Boracay Island. Since bananas are THE fruits I love most we have turned a part of our backyard into a small banana plantation growing the banana species I like most, they have the size of the usual international market bananas but are already ripe and eatable when green, acutally they are ripe for only one day, the next day already overripe, becoming yellowish with brown spots. So clearly no export bananas but very tasty.
Now I have a general question: since several banana plants are growing close togehter, stemming from the same mother plant: is it better to cut down all of them except one so it will grow especially good or is that nonsense? Must be because they multiply that way, right?
We also have the problem that the plants become only maybe 10 feet high, bear the usual bunch which seems to be to heavy for the plant because then it tips over until the bunch is supported by the ground. Then the plant dies and the bananas become emergency-ripe. What is the probable reason for that?
They are growing on rocky soil, the rocks are limestone.

On a neighboring lot the same species reaches the usual height, we also have a cook banana species here which is about 5 meters high, maybe it grows on more soil.

Regards,
Lou
