now I'm trying again with the cultivar Carabao because I found a brazilian study report on internet were they concluded that Carabao was the most resistant of all to low temperatures....
Just google for "MANGO ROOTSTOCK RESISTANCE TO LOW TEMPERATURES" and you will find this brazilian report.
Hey Miguel,
I never have had any mango die completely in my greenhouse but i noticed that the main issue with overwintering them in a steadily cold environment is the cambium dieback. So far i haven't been able to find a rule about it but my initial observation seem to suggest that the zones of the stem which don't receive direct solar heat are more subject to cambium dieback. Of course the plant doesn't die immediatly but it is pretty much condemned. I have a Mun girdled this way (that I'm waiting to graft on a healty rootstock). It was grafted on a gomera-3 clone so apparently even selected clones don't solve this issue; but indeed it may be just some pathogen that i haven't identified yet. I have a cold, damp envinronment; actually I'm surprised that some of my plant are able to make trough winter.
Pan ----- you will be glad you chose the Glenn. It is the only one of my 4 mango cultivars that fruited well in spite of the long cool spring we had here in So FL. This one can stand odd weather patterns and still produce. Very good flavor. I still lost about half of the crop to the enormous opussum that I eventually caught with a trap. His tail alone was 18 inches long!
You know, Dan, when you Floridians say "long cool spring" i'm always a bit suspicious.
I'm not sure we mean the same thing.
I hope however you are right. On my plant some little mangoes are gaining some size right now (they are still pea size, but i'm optimistic).
I choosed a Glenn also because it get watered flavour when it rains too much. This seems great for a mediterranean climate where you don't get rain at all in summer. Basically you get all the advantages of the Glenn cultivar without its main downside. I hope for the best.
(the fact that i was able to get a named glenn in europe has had a role too)
Now, i will start my fight with the critters too. Those fruit seems to have to withstand all the problems i mango can get before they can mature; first we have had a cold spring, then humidity and antrachnose, then caterpillars. Now i'm waiting for hail, mouses, sun scorches. I'm pretty sure i'll see also that before the end of the summer.
Your mango seems awesome. With a breakfast like that i wouldn't miss my cappuccino for sure!
amazing experiment, this is for a patent eh?
well, some that you should know is the mangos are very exigent in heat, always that in you greenhouse have a constant temperature of 20-25 degrees celsius in the day, just try conserve the heat in the winter although be a temp. of 17 degrees, is the min. for the fructification in this plant .
when grow more of 3 meters, what you doing?
Ehehe, no patent, no, it's just a bunch of old ideas putted altogether (plant covering, thermal mass, solar greenhouses, and so on).
Mangoes are exigent in heat but they manage to survive to my winter. However, i think they would prefer some stronger temperature fluctuation during winter, but i'm unable to provide them.
During summer we have 3 months with decent temperatures (im speaking of daily max between 28-35C/82-95F) so my plant usually don't complains during summer. It should be enough to ripe some fruit, but i miss the definitive proof.
Regarding what it will happen i get too much success with my project (i mean my mango reaching 3 meters) i don't worry about that yet. I would hard prune it back to original size; i don't see that as a problem.
