mulch holds in moisture and is not a good idea for plumerias as you want the soil mix to dry rapidly.

tdogdad....what is your input toward the below mix and if its ok what ratio would you use for plumerias

humic compost....pumice....and NAPA floor-dry #8822

thanks

I do use a thin layer of mulch on top of the soil in all my pots, though my environment in TX is a bit different from a lot of folks here on the forum. I normally also follow Bill's expertise in all things plumeria. However, TX summers can be pretty harsh, with intense sun, wind and temps that can go over 100 for many consecutive days, all of which adds up to really dry soil. I typically have to water thoroughly every other day and spray leaf canopies on in between days. The thin layer of mulch helps keep my pots from drying too fast and helps keep the soil from washing out when I water. I do however, use a very fast draining mixture of cactus soil and Perlite in addition to a layer of rocks in the bottom of my pots for additional drainage and weight. The mulch I use is also a very course hardwood mix.

federal hill- I am not a soil scientist or expert. I once used cactus mix with pumice and perlite because someone said it was good. I later switched to Big R (redwood chips), turf n tee (fine lawn soil), pumice, and perlite because someone else (Jack Morgan) convinced me it was better. I like it very much so far.I have used mulch and had problems with rot. I have used rock and burned stems. I have used pretty little plants that also needed more water than the plumeria. I have just done a ton of trial and error and continual change until things seem to work. I know many collectors and growers and listen to what they think. But when it comes down to it, I just have experience and a boatload of mistakes. Bill In other words I do not know what #8822 is.
