What's your honest review of worm castings for houseplants — noticeable difference or placebo?
I started using worm castings on my pothos and ZZ after reading the hype, mixed a couple handfuls into new repots and used a thin topdress on older pots. After about three months the pothos put out noticeably faster growth and darker leaves but the ZZ barely changed, and I did get a small case of fungus gnats when I overapplied. I'm now trying light topdresses monthly instead of mixing in large amounts because I suspect balance matters. Anyone else notice big differences only on certain plants, or can you share exact amounts/frequencies that worked without causing gnats?
