They're looking quite healthy. Of course, you won't necessarily get the same as the parent plant and it will take you a long time to find out what they're going to be like. If that's not an issue then no worries. Otherwise, it's just better to buy a grafted plant of the variety you like.

Yes theses ones I am experimenting with, you know over wintering them and seeing how big they can get in a year. I might sell some also in spring. Something that takes 6 years to fruit does not interest me lol. I will be picking up a tree or two this year for fruit. If I can find one that can take cooler temps. Something for zone 9 would be great! I'll see what the store has this spring. Thanks for the comment

I bought a mango fruit from store just to get the seed. It was sold as Kent. Seed germinated quickly and now the seedling is 15 inches long after pruning.

3 new shoots growing. Fun and beautiful plant to grow, although it may never set fruit here in Finland. I grow it indoors under some growlights.

Even the humidity has not been a problem, not a single leaf has turned brown or anything. I'm quit surprised of that!

I saw somewhere that they were growing dwarf Mangos in greenhouses out in Japan for commercial fruit production. If there is the will, there usually is the way.
