Cold hardiness amongst Cocos nucifera

[GottmitAlex]

Well, winter is almost through. I just want to show the damage winter has brought on my coconuts. The golden malayan dwarf, such as it is being the eldest etc, is more susceptible to cold than the green malayan dwarfs. Here are several pictures in order to appreciate the post-cold damage. The exception (among golden cocos) being my storebought(supermarket) dehusked golden coco which germinated in my greenhaus. I believe the reason it did not present as much damage as the golden malayan dwarf is because this golden coco is a tall variety.

These 4 cocos were unprotected this winter. Except for the brood lamps trained at the soil when temps fell below 10C.

Our lowest low this winter was 38F. However it remained cool high 40's/lower 50's as our lows.

I do believe that golden malayan dwarf cocos are less "cold hardy" (or more cold sensitive) than their green counterparts.

Two more pics of the golden Malayan dwarf coco fronds.

Yep, that's how mine looks after winter's over, in fact it looks worse because it is too big to have any protection now but that's the price of pushing the climate range I suppose.

I agree. Here again, neither this or the other three cocos were tarped/draped this winter. They only had the 75-125watt brood lamps whenever temps fell below 10C. 

I think the golden malayans are more cold sensitive than the green.

Ive only ever seen golden Malay dwarf's for sale in Perth but I wouldn't mind trying a couple of other kinds if I could ever track them down.  Our climate is not quite right for coconuts but it is close enough that if there were a type of coconut that was a smidge more cold tolerant they may just do ok in the right spot. My golden Malay dwarf comes out of winter looking pretty rough but it seems to be getting tougher and it certainly gets very little protection these days, who knows how a different type would perform.

That is not bad! Given the Corona and La Quinta coconuts, I believe you will be successful. Are you near the coast or a bit inland?

12 miles inland

You should get plenty of heat and lows cannot be bad compared yo Corona and La Quinta!

Altas temperaturas son importantes,lo que inducira a que el cocotero cresca a

pesar de bajas temperaturas nocturnas.

En el primer mes del anio ya puede

empezar a crecer.

La humedad es muy importante, es la diferencia en crecer o no.

Segun el color del brote,unos son mas

resistentes que otros.

En Costa rica los de brote naranja o verde

azul grisaceo son mucho mas fuertes.

Es bueno poner una cama de estiercol

de caballo en invierno como alcolchado.
