The worm bin picture displayed above is an example of how to separate your worm castings and your red worms. By adding new bedding and introducing food in this new area, you are able to attract most of the red worms to the new area. It is best to give the worms about 1 - 2 weeks to move to the new area and then remove the worm castings from the other side of the bin. Be sure you do not add any food to the old area and that you cut off the food supply to encourage your red worms to move to the new area. You may find a couple of worms in the old castings after a week or two. Just help them out and move them over if you wish.
Red worms must be removed from their bedding; which is full of castings, in about 3 - 4 months. The castings become toxic to the worms and will affect their eating and reproduction if they are not moved out of their old area. If the worms are not moved out of the castings after 3 - 4 months the worms will digest the old bedding etc. Then you have vermicast, which is not as healthy to plants because there is less nitrogen, potassium and phosphate in the mix. Also, your worms will probably become part of the compost if they are left in toxic bedding.
Worm castings can be mixed in with your soil or used as top dressing for your plants. One word of caution: If castings dry out, they may blow away due to their light weight. I recommend mixing it in the soil to avoid problems. Enjoy the benefits that vermicompost offers: improved conditioned soil, better aeration in your soil, antifungal properties, improved moisture holding (holds up to 9 times its weight in moisture), less salt in this fertilizer/soil conditioner, faster germination of many seeds, improved vegetable/fruit production, and healthy plants.
