.. I'd love some more hyacinth. I've got a 4000 gallon koi pond where the
25 I bought just aren't doing well,

They will never do well in a koi pond. The koi eat the roots. I grow mine out
in the goldfish pond or veg. filter then put them in the koi pond for a week
then back into the other pond. Jerri
