What's going on everyone? Welcome back to the podcast. Today I had to harvest out my worm castings and I figured what I would do is talk a little bit about four different ways that you can do this because I think when most of us start vermocomposting, we're all excited in

0:15.8

gung-ho and then when it comes time to harvest them, we think, oh my gosh, how do I actually

0:21.0

do it without harvesting out all of my worms as well or just in a way that causes them as little distress as possible?

0:29.0

So let's go ahead and talk about four different ways that you can do this and the recommended method that I have as well.

0:35.6

First though we do have to understand how earthworms respond to different stimulus so food,

0:41.4

moisture and light. Our wiggly friends, they love the top six to

0:47.4

eight inches of compost, leaf litter, food scraps, etc. This is even more true when we're verma composting because we're creating this beautiful environment for them.

0:56.7

It's actually crazy to see how composting worms respond to anything in the curcubit family, like a pumpkin, a cantalope, or a watermelon.

1:05.0

They decompose really quickly and the micro-population around those particular veggies or fruits is insane and worms just flock to them.

1:17.0

So worms are definitely attracted to the all you can eat microbeafet, but they are also attracted to moisture and that's why a poorly ventilated or

1:24.4

overfed worm bin will have excess moisture pooling at the bottom and lots of

1:29.9

worms will be hanging around that moisture. The one thing that all Earthworms hate is sunlight.

1:36.6

They will do anything they can to avoid bright lights. So now that we know what worms find attractive, what they want to go towards, and what they find

1:45.9

repellent, what they want to run away from, that will help you design a method that you can actually

1:51.4

use to separate your worm castings, right?

1:54.3

It just cause and effect.

1:55.8

How do these worms respond and how do we manipulate that?

1:59.5

So here's the craziest one and this is one I haven't done personally because I think I value my time a little bit too much but you can go the manual sorting.

2:07.5

Manually sorting thousands of worms. So there's about a thousand red wiggler worms in the average pound from verma compost.

2:15.0

That's certainly possible, but it's very tedious.

2:17.4

But I do know some hardcore verma composters that will do that, and they find it a pleasant way to spend hours kind of like knitting right so if that's your thing

2:25.7

you can definitely just manually sort and you're in a good spot
