Mangosteen unprotected in San Diego
« on: September 19, 2020, 02:54:54 AM »
I tried growing purple mangosteen about 15-20 years ago but killed a few trees and after doing a lot of research, I realized that it would be nearly impossible to grow and fruit it in San Diego unless I had a greenhouse.

Anyways, I gave up on growing it and whenever anyone asks me about growing mangosteen in San Diego, I tell them not to bother because itís a waste of time and money. I told this to my friend that lives just a mile or two from my house and when I visited him today, I was shocked to see that he ignored my warnings and proved me wrong. I told him last year that the plant wonít last one Winter unprotected outdoors and he planted it into the ground last year anyways and I was surprised to see the plant was still alive and even looked relatively healthy.

Heís had this plant for 6 years and had been keeping it under his patio and overhang of his roof for the last several years and also slowly adapting it to the full sun/cold.

Last year, around late Summer or fall, he planted it into the ground and hereís what it looks like today. I still donít think it will survive very long outdoors unprotected but itís at least survived one Winter outside. On a side note, last year, our Winter was very mild and I did not get frost for the first time in many years.

The community I live in is made up of houses packed tightly together with relatively small yards. I believe the large amount of fruit trees in his yard along with his Koi Pond is bringing up his humidity. He also waters his trees with pond water and perhaps the mangosteen enjoys that, I donít know.

All I know is that my mangosteen didnít seem to like temperatures below around 65F-55F. Mine died the firstWinter I put it out. Perhaps the close proximity of all the homes is holding in the heat from the surrounding area? I have no idea.

I have a prodigy that fruited at not much bigger than that. It is tougher than the others and thrives on neglect.

Really interesting Simon!  Iím sure all the stones surrounding the tree help radiate heat during the cold evenings as well.  Iíve been wondering with the rapid acceleration toward climate change comes a more ideal environment for subtropical/tropical plants near coastal SD.  It will be interesting to see how our winters start to change in the coming years. Or maybe the mangosteen loves all the ash in our air  ;)
Would love an update on your friends mangosteen following this upcoming La NiŮa winter.

I highly doubt it will survive another Winter but he already proved me wrong once.

He said he did not protect it in any manner during the winter. I didnít ask him if he recently protected inthe heatwave.  Iíll keep everyone updated.

protecting from prolonged dry/low humidity periods may be more essential than temp. they both matter obviously

The most practical aspect of this subject is whether the tree will in later years capable of producing flowers and then ample good fruits! SHV's comment appears to be interesting and thought provoking not for just your zone but other subtropical and temperate areas round the Globe due to fast advancing climate changes.

Roblack is correct. I had one for a full year, about the same size not as bushy, behind my 30í avocado tree and under the eaves but it succumb to 2% humidity and Santa Ana winds in fall. Keep us updated next year see how itís doing.

Yes humidity and dry wind are key things to think about. Climate change isn't sweeping over us at that type of rate. You can look at meteorological maps that show tenths of a degree per decade and equate it to latitudes, or look at projected changes in heatwaves or whatever but it doesn't mean you will suddenly be able to grow durians in California.

Yeah, his Koi pond and all his other trees are definitely increasing the humidity. Iíll try to stop by in late Winter to see how itís doing. Iíll keep everyone updated. If we get another warm Winter, it should survive.
