Growing Mango tree in north of Portugal
Greetings, i'm new to the forum and i'm seeking some expert help from other growers, i'm no plant grower, in fact i know very little about it, but i'm trying to grow a mango tree from seed anyway. :)
I live in Portugal, Gaia (Porto area), which is hardiness zone 9 according to following picture.
It's very sunny and a warm climate during spring and summer, the winters are windy and very rainy, there's no snow, it's a "very rare" event. There's only a winter morning fog and very light frost over the grass that we call "geada", and most plants support it very well.
It's possible to grow pretty much everything, the most common are the lemons, orange, mandarin, lime, grapes, physalis, olive, nuts, figs, apples, pears, strawberrys, beans, tomatoes, corn.... with little or no effort. The not so common but still possible to grow outdoors are bananas, brazilian tree tomato, mango, papaya, pomegranate, loquat, pineapple, kiwi and some other exotic fruits.
I planted my mango seed about a month ago (03-04-2010) from a store brought red mango from Brazil that looked like this:
I was anxious to see something coming out of the earth so i unearthed it a few days ago, i found a root with about 7cm long and put it back again gently. I also found a very small and green woody....well "stick".
It has no leaves and it's growth seems someway halted, the seed however is turning black and mouldy. It sits on a pot on the window of my room and gets about 8 hours of sun and the soil (native soil, which is pitch black and clay, which i believe to be very fertile) is kept fairly moist i water it once a week or when it gets very dry. I'm really clueless on what may be causing this since it does not seems dead.
In future i'm thinking about growing some cocoa trees that a friend of mine will bring me from Venezuela, i've never seen one around here, altough i think it may be possible to thrive since most tropicals do, even if they grow VERY slow. What do you think?
I need some help, thanks in advance and sorry for the long post.
