I used to add it to the existing dirt around bushes and yard and what not. but my neighbor last year reused his previous years and all his plants did un*^*&%%*& believable! I am gonna use what I have in my pots this year hoping for similar results

I usually dump my pots all into a big pile and reuse the mix next year, sometimes mixing in new with the old. Any pots with diseased plants get dumped in the back of the lot and are not reused.

Use it again. I might follow up peppers with lettuce in the 2nd year. I try not to use more than 2 years for toms and or peppers. They get diseases too easy.

But I make and use a lot of soil.

I spread half the used mix and blend the other half with fresh each year. Only done it for 2 years, but there have been no noticeable adverse effects.
