Here is my neighbour's jackfruit tree! This tree is about 30 years old - my neighbour was given a jackfruit by a friend and after eating the fruit she sowed about ten of the seeds in her backyard. Soon there were 10 little saplings and one of them was allowed to grow into this sturdy tree. It did not bear fruit for the first few years though, until one day they poured a whole lot of manure (courtesy the milkman's cow i'm sure!) around its roots. And then there was no turning back! From 4-5 fruits that summer, the tree went on to yield 40-50 fruits every year.
Sadly the upper branches had to be cut when the house was renovated, but it still stands firm and continues to bear fruit every year. The tree had one fruit on it when i took this picture (we did our bit to help eat the rest!) and here it is.
Here is another tree from the backyard. This one too was trimmed many a time. Because of the nicks and cuts, the tree now bears fruits in clusters of two instead of single ones. This isnt too good - the fruits dont grow as well when they compete for space and sometimes ripen early because of the constamt contact with each other.
