Mulch alternatives

[Nefarious]

I just bought a property in coachella desert and I have an area that has some palm trees. Before today it was covered in landscape stones mixed with sand. I removed most of the stones, I'll get the remaining ones later. I'm wondering what the best mulch alternatives are.

Welcome @Nefarious.

I'm not from your area but I've done some research on it and maybe that will help get you started.

First, let's start with a definition for communications purposes. According to Bob Vila, "Mulch protects the soil surface, while compost feeds and improves the soil itself. That’s the core difference. "

So, let's talk mulch in Coachella. In your climate, you need a mulch that retains moisture, moderates soil temperatures, and resists blowing away in your desert winds. There is a pretty clear winner that meets that criteria.... Coarse Wood Chips would be the top choice for trees and shrubs and landscape plants. Excellent long‑term moisture retention, resists wind displacement due to large, chunky pieces, and breaks down slowly.

That choice is great for what it does, but if you are after soil improvement, you need to consider organic compost which adds nutrients and organic matter to the soil which helps retain water and improves fertility in garden beds.

Lots of other alternatives there such as straw, shredded redwood, gravel/rock, and palm fiber mulch... but of all these the consensus according to my research for trees, shrubs, plants is the coarse wood chips...recognizing that if soil improvement is important to you compost should be considered.

That should get you started...hopefully

Hi and welcome. Some options are - as above. Use raised beds or sunken beds and fill with proper growing soil. Dig in chicken manure or well rotted cattle manure Into the ground.
GardenersWorld.com is doing an article on mulching. Just received an email.

Something chunky is good. It makes pulling all the seedlings easier, at least if the palms are species of Washingtonia. A really thick layer of arborist chippings works well too.

@Nefarious, one way to follow a single thesis through what most are suggesting is Hardwood Bark Chips. Specifically they have lignin as opposed to pine bark. Lignin is related to the composting function in important ways. As a form of ramial wood the nutritional values are more appropriate than with internal structural wood. Water though is more problematic, and a porous stone or clay would also assist as a water wick tempering mechanism, dried clays and products like Turface (calcined clay) can hold more moisture and retard surface evaporation longer that mulch, which is more a surface area to internal surface area function. Also and possibly king of category, the charcoals have massive internal surface area to outside area ratios while boosting carbon, and thus when you add water you have C,H,O those being the primary nutrients. My suggestions have a weakness in amino acids or proteins, which I value the manure composts for as a good additive.

Charcoal is black, you certainly don't need more heat in the Coachella valley right now!

Yes and Putting it on the soil rather than scratching it in is not ideal either. I should have mentioned that it's a mix component. The top few inches where the oxygen is doing its best work is ideal.
