asin-asin or cekur manis.
Plants put a halt when weather is too hot and unbearable. Shoots are not coming out. Plants somehow quicken the stage of blooming and bearing fruits. I can really understand that, because excessive heat is a stress to them. That will trigger a signal to the plants to produce babies by flowering and fruiting
I remember how trees are trained to bear fruits. Nangka is the easiest. There are time when trees keep growing, and enjoy the growing period so much that they are not keen in fruiting. Father used to take out his parang and slashed the bark a few times. The old way is someone would slash with parang, and shout "Are you going to bear fruits?, otherwise I will do it again tomorrow.." Then someone else will answer "yes, yes, I will bear fruits" on behalf of the tree. In most cases, the tree bear fruits the next season.
It's about inducing stress, giving signal to the tree that are sick and therefore must produce babies. Trees don't seem to talk and walk, but they are methodical, following a standard operating procedure while growing on one particular spot.
Asin-asin is a plant growing well these few years. The shoots are cut off as vegetables, which will end up as masak lemak asin-asin, my favourite. There will be sweet potatoes, asin-asin , shoots, and shrimps, cooked in coconut milk. The plant doesn't seem to grow old, because they are constantly in a renewed stage after regular pruning. They have tiny flowers and I don't know if they end up as seeds. Propagation is always with cuttings.
A few months ago I just put several stems into the ground, very close, 3 to 4 inches apart. Yes they grow.
