I rinse them out with garden hose to get rid of all dirt and then just pop them in the dishwasher at highest temp without a tab.

tx_flower_child, I'm so verbose it's a wonder anyone gets through an entire post!

Welcome to NGA, Shannon! It sounds like you really know how to pamper your soils.

>> bone meal, poultry manure, feather meal

Do you keep chickens or know someone who does? There are a few chicken-growers, and more fans, over in the "Farming Forum". Those threads are more active when people are buying chicks.

I'm guessing that you have a lot of live soil microbes even in pots. My theory is that a thriving and varied soil population actually discourages plant pathogens - by competition, if nothing else.

And I think that some soil microbes fight other soil microbes, and that many plant roots excrete things to attract and encourage the beneficial ones.

I don't expect to be able to maintain thriving soil populations in my pots, so I keep my potting mix much more boring than yours. Mainly bark plus commercial potting soil.

If I had all your ingredients, I'd be feeding them to my raised bed soils, but the main organic source I have is bags of composted, dried manure.

I used to be fanatical about bleaching (chlorine) all of my pots after they were washed in hot, soapy water. Now I just add some bleach to the soapy water, let the pots sit for maybe 10 minutes, swish, rinse and let them air dry. Sometimes I don't add bleach if it's bigger pots that are going to hold larger plants. Washing all those 4- and 6-packs with a toothbrush gets tedious so I try to cut corners elsewhere. No issues here. I will say that some of the plastics do get brittle after being bleached numerous times and are more prone to cracking.
