Hi.
I have used worn tea a bit over the years when I can get it free.
It needs to be diluted a far bit 10 to 1 or more.
Mine came from a orchid nurserys supplies who used it a lot on his orchids.
I have used it diluted at 10 to 1 as a tonic only
Once a week or so on orchids and when plants seedling in the garden
the same.
I would not use it as a general purpose fertilizer but just as a tonic and to put the microhiza back into the soil etc.
Same on newly potted orchids.
Cheerio
Ron
