Has anyone here ever sprouted a grocery store coconut? I want to give it a try and I've read that it can be done.

My local stores sell coconuts with the husks still on them, so I was hoping one of those might work. The biggest challenge I'm suspecting will be keeping it warm enough, as my hottest days have passed for the year. (Too bad. Had I known, I'd have tried it then.) Sounds like they need to be kept quite warm while trying to sprout. I'd read 90+ degrees F.

Anyways... Anyone here ever tried it with success? Any tips? I found some info online for doing it, but was curious if anyone here has successfully done it. Smiling

Well, I picked out a coconut. Going to set it up in a pot and see what happens. Here's hoping!

I haven't grown one from the store. But we brought one home the kids found on the beach. Hopefully you chose one that sloshes when you shake it.

We buried ours with the 'bottom' an inch or so deep in a big pot of soil. I don't know which side is up, but when they fall out of the tree from 50 ft up, does it matter? Ours sprouted really fast, in just a couple weeks. It grew equally quickly and soon the leaf tips were touching the walls on both sides of our 10 ft wide sunroom.

Just about the time I was panicing about it hitting the ceiling, we had our coldest winter ever. We couldn't keep it warm enough and it didn't survive the winter.

Ha, what fun, all of that.

"We buried ours with the 'bottom' an inch or so deep in a big pot of soil. I don't know which side is up, but when they fall out of the tree from 50 ft up, does it matter? "

the 50 foot fall might 'plant' it some way, then washing around in tropical rain and waves might undo it anyway. Googling growing a coconut leads to lots of hits of possibly unreliable info (a reddit question on the topic of "coconut not spawning??" Blinking ) but here's a dot org

From Palmtalk.org chat:
Hi Jason,

I would guess it's dehusked, right? If not, you can plant it in a pot with very sandy soil. Let it roll on the ground and plant it on the same orientation where it comes to rest, and about halfway into the soil.

If it IS dehusked (like most they sell at the supermarket), put it in a bucket of water overnight, then you can place it inside a ziplock bag, or just plant it halfway into the soil with the embryo eye just outside of the soil surface (this eye usually is located in the largest third of the coconut and looks a little different than the other two) then throw a piece of plastic on top to hold the moisture. Keep it a little on the dry side, but you should see condensation in the plastic surface.

Remember, coconuts NEED warmth and humidity to sprout; especially warm nights above 68°F. Check it daily and spray fungicide as needed. Good luck!

PS- Remember to select one that has no cracks on the outside! Also, the one with the most water content slushing inside, and healthy eyes.

Plant it and they will come.

I picked a coconut that was larger, with the husk, with lots of water sloshing around inside when you shake it. Didn't notice any cracks anywhere. Hopefully I picked a good one.

I actually haven't planted it yet. Our temperature plummetted and it's kind of cool out now. So not sure I'm going to be able to keep it warm enough.

I could try it indoors where it's warmer perhaps? Too bad my attic has no skylights. It stays very toasty and humid up there.

We didn't de-husk ours. They sprout with a husk all the time. AND, the kids had painted their coconut before addressing to themselves and putting stamps all over it (really!) so we couldn't get rid of all that. Rolling on the floor laughing

Does the light matter before it sprouts?

I believe for sprouting light is not a requirement, humidity and warmt is. we even avoid keeping coconut in dark place since it tends to sprouts even better in dark.
I also started grow some coconut in pot lately after finding few variegated seedling. Coconut makes a good companion plant in a pot also. You can dwarf them if you want and some people have it as a kind of bonsai subject, even for 20-30 years in a pot. So a medium-large terrarium with artificial light is might even work I guess in non tropical land.
The seedling I found Thumb of 2024-08-21/tofitropic/56f062
few variegated stripes Thumb of 2024-08-21/tofitropic/8cdc5e
A few times after in a combo planting with Asparagus, Syngoniums, Asplenium and a Ficus

The Coconut roots are raised and exposed to slow their growth and for easier petiole reduction to keep it dwarf

Maybe I'll try putting it in the attic and see what happens. At least I'll have the heat and humidity that way. It's been staying 86 degrees F and higher up there.

I didn't end up doing it. Life got kind of hectic the last few weeks and I didn't get around to it. Not even sure if the coconut is still viable?
