Is it okay to mulch with nothing but dead palm fronds?

[Debb]

Hi there. I live in a 10a Florida neighborhood with tons of self-cleaning palms. Everyone throws their dropped fronds away. So on garbage pickup day, I collect many fronds, cut them down with scissors and loppers, and throw them in my garden beds. I used to use wood chips as mulch, but this is a free alternative, and I don't mind chopping these fronds down to make it work. 

I've been doing this for a few weeks, but don't want to hurt my garden beds if the spent palm fronds are completely devoid of nutritional value.

Is this an acceptable alternative to regular mulch or wood chips? My neighborhood doesn't have an aggressive pesticide or fertilization schedule, and I don't yank dying fronds off other people's palms. I just pick up ones laid down by their trash cans. My friends think I'm nuts, but I think I'm being resourceful! So many people online talk about fallen leaves as a great mulch for overwintering, but I don't really have that.  As a note. I pull off the leaves from the main stem, cut those down with scissors into 1 inch squares. Then I use a lopper to cut the stems down into 2 inch bits.  I wait for the palm sheath to shrivel and dry out to lop them down also. I try to use everything.

Any thoughts would be appreciated.

I don't think there's any major issues with doing this other than the fact that often palm fronds decay slower than wood mulch.  There could potentially be an argument that you might bring disease vectors into your yard, but IMO if they're all coming from your neighborhood you're not really increasing or mitigating that risk in any case.

My own thought.

Thank you for your reply. I didn't realize how slow palm fronds decay in comparison to wood, but my wood chip mulch decays like crazy here with our irrigation schedule. So this might be a welcome respite to my gardening bill! It's predominantly Christmas and foxtail fronds that I pick up. Royal palms are just too much work to break down and I don't have large enough loppers. 

Again, thanks!

I do the same with my own spent smaller palm fronds.  I burn the larger ones and use the ashes around palms and in flower beds.  I also chop up fallen branches from deciduous trees in the yard as mulch.  It does seem to improve the top layer of soil.

Sweet! That's good to know. Do you use a mulch over your ashes to keep things from washing away, or is there enough debris in your beds to keep them in place?

Yes, I work the ashes into the soil below the mulch otherwise the ashes can cause runoff when watered if there's too much of it just sitting on top of the soil.  Same thing with use of coffee grounds which palms seem to like.

@Debb nice to meet you!

I have a palm jungle and no lawn and lots of palm leaves, and mixing dead plant stuff with wood ashes makes them rot a lot faster.

To hack up royal palm fronds, get a machete. Great after a bad day at the plant, clinic or office to let off a little steam.

It most certainly is the best food a palm can get. That's what they eat in there natural habitat. I just chop my ones up when I get around to it if there green or desiccated either way chop them up it’s fantastic mulch. Your garden will love it. I  don’t look at the botanical garden good look nice wood chip or super good looking mulch point of view I look at practically that works creating a natural environment in my garden. And any  gardener will agree any mulch is better than no mulch be it a nice botanical garden or a paradise created at home if it works keep doing it!

This is so great! I'm helping my garden! Yay!
