Cocos nucifera on Madeira Island

@Cluster I don't know, I want to think it's outside, I didn't know they used greenhouses.

By the way,  I've always seen 18 °C and 64.4 F and not 64 F for the tropical climate.  Do you know if the IPMA published the 1991-2020 normals yet?

Hello @Pargomad

The official is probably 18 C and not 64F, but sometimes you see the 64F, in any case 17.6 is still closer to 18 than 17, however if you are going to consider 81 till now, there are probably  few areas that already surpass 18. I think it makes no practical difference, do know that Havana has seen lower temperatures than South Coastal Madeira, so there are a few things that favor that cool tropical label for the warmest areas of Madeira coast.

They do have some stuff in the greenhouse as they are not sure they would survive outside, but I know that supposedly they have Euterpe oleracea outside and Annona Muricata fruiting. I do have a small Theobroma cacau that I put outside in a sheltered place from winds (My place is super super windy there) and it was putting leaves in winter.

 

Here are photos from last summer form Paul coconuts:

Trimmed as always but strong and healthy:

I could count 3 big coconuts there. Will try to visit the place this summer.

And here is the highest elevation coconut (200m/656feet) that I know of on the island, late winter 2022:

Supposedly lately it has been given bunny manure so it has been growing stronger and faster.

Hello everyone,

Last summer I noticed that the neighbor's coconut got a deficiency:

Would anyone know what it is? Maybe boron due to lack of irrigation in the summer? (I noticed no one was there during August 2021, maybe the irrigation was malfunctioning?)

 

The coconut has recovered slowly during the winter and spring and it seems the newest fronds are growing healthy again.

Hello I believe you meant manganese deficiency right? At least this is what comes up with frizzle top. If it was frizzle top I believe this happens more in winter due to cold weather. In this case it happened middle/end summer. 

I am more convinced this is Boron deficiency as the leaves show wrinkling and I found this image online that is similar:

From what I have read boron deficiency can happen in dry conditions where the palm will not absorb it.
