we do not have fruits plants in the nursery here, i mean those fruits that imported from western country, such as Orange, Avacado, Peach, Nectarine. what i'm trying to do is grow them from seed, do i have to wait till the whole fruit rot, then only the seed consider as matured, or i can eat the fruit and straight plant the seed?

Buy the plant, that way they come with a warranty.

buy a plant

eat the plane rise the seed and plant in good soil...start it in a pot first heres a couple sites that might help u out good luck. my mother grew an Avacado tree

if you dont want to buy a plant, you just eat the fruit then plant the seed, haven't you ever planted an apple seed or watermelon seed after eating the fruit as a kid they always grew for me, they might not have lived but they did grow. I f you take care of it you should have no problems. althogh dont expect a miracle overnight it will take years for a tree to grow. try it whats the worst that can happen

I have always used the seeds from my vegtable or fruit ,I wait till plant dies for the seed of flowers.Now the seed of a vegtable it tends to rot also so eat it.Let that seed dry in the sun, or on a paper towel .If your planting right away then do so as soon as it drys up. If your waiting you can refrigerate it till time.I have done alot of my gardening that way.Its fun if you have kids also they can actually watch it grow and understand that nature of things. See yaGood luck

If you can't get the tree locally, you can mail order them... Here's one site that sells fruit trees:http://gurneys.com/default.asp?sid=500280&eid=&bhcd2=1144950236

In all of the above-listed plants, you would never want to attempt to grow from seed. There are several reasons: it would take over ten years to get fruit, the seeds are often sterile (the commercial fruits in the stores have been crossbred to create the 'perfect commercializable fruit' rather than the 'perfect seed'), and the plants you listed need to be grafted in order to grow well.It would be a shame to spend 10+ years nurturing a tree only to find out it will never produce because it is sterile.Also, consider this: if the nurseries are not selling those trees, the perhaps there is a reason (ie: they do not grow well in your zone).
