It seems worms are going to be in short supply for all of 2021. I have not been able to buy Eisenia fetida from any reputable supplier.
Worm plans for 2021 as of May 9th 2021.
Our large beds are balanced to grow worms as fast as possible plus we’ve set up small trays to encourage maximum cocoon production. With ideal conditions one adult can make 12 adults in 3 months but ideal conditions never exist.
Once a month we open one bed, sort out the sellables and add that number to the website inventory. When they're sold out we're out until next month. Each bed is emptied every 4 months.
