Advancing with mangos
I just tought would have been interesting for someone in same zone as me to see what i have done till now about trying to grow mango out of they climate.
For me the main point is the winter, wich can be very cold. I think (even if i can't be 100% sure) that i have enough heat in summer to let mangos ripe (at least the early one) so the point for me is keeping the plant alive from december to march.
For now (it is a work in progress, i'll take the building part back in september i guess) i have built the concrete part of the work (this part will stay there all year long).
You can see it there:
This is a nice Glenn mango that i have been finally able to buy. It also has some fruits, wich i'd like to see ripen this summer, so i can at least undesrtand if mangos can ripe here. If i prune back the new grow (i'd like to get a compact plant, i NEED a compact plant to keep it covered) is likely to see it drop the fruits, right?
The south wall (wich is the one in shadow in this picture) is 3 feet tall wil the east wall is 7 feet tall. I putted the block around the plant because, in my opinion, i really hard to avoid cold air to pass on ground level when you build a structure: in windy nights even little holes can drag a lot of heat: plus it is easier to build a stable structure if you have some concrete block to rely upon.
I filled the block with dirt to increase their thermal mass a insulation: the blocks are this made:
I can give detailts on the project if someone is interested, but i don't know how much this is usable in usa.
This is a lemon planted from my grandfather: it lives pretty well here, on milder witer it doesn't even need a cover:
This is a citrus instead: it does some nice sized fruits.
Back on mango: this glenn in ground of the pic above is starting to show those black spot on some (3-4) leaves. Should i be worried? What i should do? It has been putted in ground just 10 days ago, it looks like it is willing to put out some new growt, but it has developed also those black leaves wich i don't like.
Here's a pic:
I already gave some copper and sulphur but doesn't seems to have any effect. Can be the excess of sun and heat? Here hasn't been exceptionally hot (85-86F) but plant is just freshly planted in ground...
