Reusing soil from plants that had bud rot?

What’s up, guys? Looking for some opinions….

I’m a guy who “religiously” amends and reuses my soil. But… I dealt with some late-season bud rot in my (small…) outdoor grow last year.

What do you all think about amending, “cooking”, and reusing this same soil for 2022 outdoor?

On one hand it’s quite likely there are mold spores overwintering in my soil, but in the other hand those same spores are overwintering all around my yard (and everyone else’s)… Mold spores really are everywhere - the hey just show themselves when the conditions are right (high humidity, plant tissue damaged by caterpillars, etc, etc)…

Thoughts? Feelings? I’d hate to sacrifice this soil… Still got a lot of goodness in it. :)

Bud rot is often the result of insect or caterpillar feces. Be sure to use a good ipm strategy, especially during budset.

Good advice, and Regalia is an excellent organic product for PM control...You can use it as a foliar, or a soil drench....and then if you really want to be smart, add Venerate, for bug protection...That's mostly my IPM.

A little pricey but it will last you!! Probably 2 years outdoors...and keep your tomatoes / veggies happy!!

All those IPM solutions are great, but a well nutrified and mineralized substrate, flourishing microflora, proper watering and RH in check, should be enough to combat the ungerminated spores of bud rot. If insects are an issue then the IPM is necessary as well.

He's growing outdoors. Not sure how one would keep the RH in check???? And of course, there are mold spores everywhere outdoors.

As I said then, just ignore the RH. Healthy plants are far more resistant to foreign shit than you'd think. There are some special circumstances but In my 20 yrs of growing I've only used neem oil outdoors and scraped it to go for neem cake.

Plants have a defensive mechanism called SAR. The presence of Trichoderma aids in the digestion of chitin, which turns into chitenase. This is what helps trigger the systemic acquired resistance. MICROBES!

I say use it... Like you said there are mold spores everywhere. If the weather is right for mold... Then I don't think new soil is going to prevent it.
