What Should I Do If I Have A Tray Full?
Once you fill one tray and it looks like worms soon will not have anything to eat, load the next / new tray above the old one. As there are holes in each tray the worms just migrate through these into the tray above. Prepare the new tray in the same way as you did the old tray.
Please note if you are using a moisture mat this needs always to go on top of the freshest waste – so if you are adding a new tray remove the moisture mat put the new tray on top of the waste in the existing tray and add waste into the new tray and the moisture mat on top of the fresh waste.
The worms will go up and down through the holes – you will see evidence of this with tiny specs of dark specs of compost. One thing to note is that sometimes as the worms work through the waste and reduce the volume which then means the compost sinks inbetween the trays meaning it’s more difficult for the worms to work their way up and down so it’s worth checking for gaps every now and again and if there are it’s simple just pop a bit of waste into the gap.
Once you have reached the top of the top tray (which will take some time as the worms reduce the volume on a daily basis) then most of the worms will have left the bottom tray and this compost can be used. Empty it out and then this tray can be used to go on top of the working tray so that the worms continue working their way up and you are rotating the trays.
There is bound to be some worms in the compost that you use – this is fine but if you want them all back in your wormery – just expose the compost to light and skim off the compost. The worms move away from the light and so will form a pile which you can pop back into your worm bin.**
