Harvesting a tray

Post by Lilwriggler » Fri May 24, 2019 10:43 pm

I’m in the process of adding my next tray, will start putting food in it in the next couple of weeks. My bottom tray weighs a tonne, but it is mostly broken down. There is however still a bit of bedding material not quite rotted off and still quite a few worms, odd ones in the sump too. Should i wait until they have completely vacated that tray before i harvest it? It’s consistency is on the wetter side of crumbly, but i am not generating leachate. The tray above is mostly bedding material and a shallow layer of vermicompost, but it has loads of worms in it so i think they will be happy, may get my new tray going a bit more before i harvest? Would you seive the harvested tray to make sure you dont lose any of the herd?

Hi, I would start putting a small amount of food in my top tray a day or so after putting it in position. Use the four corners to ensure you don’t over feed the herd.
I leave my old bottom tray in place for a few months before harvesting and using it. I have four trays in one set up and five trays in another. I harvest the bottom tray once per month and move it to the top position. This means my trays have four or five months to finish and mature before use. This arrangement works well for me.
Given the length of time the worms have to completely finish the tray I find I have very few worms in the bottom tray when I come to harvest it. I just leave those few worms in the castings, they end up in the garden or allotment when I use the compost.
It sounds like things are going really well for you and your herd well done .

Your herd must be processing the food quickly! To be fair my bottom tray must be 6.5 months old ish. I just need that confidence to see enough castings in a tray before i move up. Enjoyed having a cardboard layer on top and now watching them come through it. All the original coir is gone which is also great.

First harvest completed today, which was satisfying. Just couldn’t decide where i wanted to use it in the garden....... tried to return any eggs i spotted back into the wormery as well as all the bigger worms.... :cool:

Congrats on getting your first tray finished. I remember it’s a nice feeling and the castings seem almost too good to use.
Now production is underway remember this is the first of many.

Well done
Willy
