Our mango has quite a history, actually. We have an old friend, who lives in England, but is of Jamaican descent. One year she was visited by a Jamaican relative who brought her some mangos from home. Later that same year she came to visit us in Cyprus bringing with her the stones from the mangos, unfortunately not the fruit as she'd already eaten those! I attempted to grow the stones, purely as an experiment and with no expectation of success. Before potting them I tried to crack the hard shell without causing any damage in order to allow access for moisture. Several months later, having all but forgotten them, I noticed that one of them showed signs of growth. I nursed this for a couple of years, potting it on as it grew larger. Most of the literature I consulted seemed to agree that it took around 7 years for plants grown this way to produce fruit and that it was not worth the effort as they were stringy and tasted of turpentine, grafted plants were advised. My tree eventually became large enough to plant out and a site in dappled shade protected by other, more mature, trees was chosen. The soil here was pretty good having benefited over the years from the leaf litter deposited by the surrounding trees. Its reaction to being planted out was to go into suspended animation. Nothing moved for almost 2 years. It didn't die but it didn't put on any new growth either. Then suddenly one year it sprang back into life and the following year it produced a couple of fruit. I must admit that they were a bit stringy, but then a lot of mangos are, and the taste was certainly not of turpentine. Since then it has produced around 20 fruit a year. The time from sowing the stone to fruiting was 7/8 years, in line with the prediction. The tree is now 12 years old. I don't fertilise it relying, as I said, on the build up of leaf litter, but I do irrigate it twice a week during the hottest months of the summer.
