After the bedding material is in the worm frame and mixed, thoroughly wet the bedding material, mix again and wet, again. Allow it to set overnight and repeat this procedure every day for one week. This will ensure an even dampness and comfortable home for the red worms. On the beginning day of starting the worm bed and following up once a month thereafter, apply one quart of dolomatic lime to every two square foot of surface bedding, taking care to wet down the lime after each application to keep the dust down to a minimum. Prolonged exposure to lime dust has been known to cause respiratory problems, which rabbits are susceptible to.
Lime is safe for the rabbits only if the dust cloud is kept down.
Lime will not hurt the worms in any way. Lime keeps the worm bedding PH level neutral, or at level 7. The worms cannot and will not live in acidic soil. The lime also helps to keep foul odors and flies to a minimum. The bedding in that spot is too acidic and needs to be removed to a compost pile where it can properly break down.
