New hugel beet, to weed cloth, or not to weed cloth.

I'm building two new raised beds.  I will make them hugel beets.  I have two other hugel beets and didn't use any weed cloth.  There are a few weeds, but not many.  I had no intention of using weed cloth, and my son got in my head saying you are going to all the trouble and you aren't going to protect it, that's crazy.  Now I'm second guessing myself.  I'm extending my garden so one of the hugel's is going to be outside the old garden area and was covered in Johnson grass and Bermuda grass.  My reason for not using weed cloth is I want the worms to have access, and do what they do.  The obvious reason for using it is to keep the weeds out.  I am at the point of no return for the first bed.  My concrete blocks are set and I have dug 2' into the ground.  Tomorrow I will put the wood down and hopefully finish this first bed.  Just wondering what you all do?  Thanks.

I would not use weed cloth. It's just my opinion & I have no data or experience to base that on but it just seems like a waste of effort & money. A thick mulch will minimize most weeds. Would you rather add nutritious (to the soil critters) mulch a few times a year or replace weed cloth each year, or however long it lasts? It seems to me that the layer of cloth will prevent proper interaction of the top soil layer with the sun & rain & small critters like worms. I think around here it might enhance some mold issues. I consider hugels a natural thing & weed cloth as unnatural. The two just don't mix well in my opinion. It seems like weed cloth would prevent some desirable volunteers too.

From a completely different angle ... I'd tell my kid to go pick the weeds himself if they bothered him that much.

I'm with Mike. Don't second guess yourself. The mulch will take care of it, without adding anything unfriendly.

Seems to me that 2' of soil would keep most grass or weeds from getting into the beds. If you have some leaves available then putting a thick layer of leaves before adding the wood would be even better.

My experience with a thick mat of leaves is that generally nothing sprouts under those leaves.  As the leaves decompose they will add nutrients to the soil while making leaf mold.

Thanks for all of your input.  I didn't use the weed cloth.  I thought about lining the hole with cardboard, but decided against that too.  I didn't manage to finnish it yesterday.  My husband has chronic pain do to a neck injury.  He has been having a few very hard day, and when his pain is out of control it makes getting sleep almost impossible.  So between fatigue from digging the pit, and lack of sleep, I didn't make much progress.  I covered the bottom with wood.  Covered the wood with native soil. Now I'm on the layer where I put medium to small branches, bark, leave, some shredded cardboard, and the stuff I have for the compost. I'm almost done with this layer.  I just have to add the compost and cardboard.  Next I will cover that with native soil.  Then a layer of wood chips, more native soil.  At this point I will add some organic garden soil I bought some time ago, I will get as much of the soil out of the raised bed I'm replacing, as I can salvage.  I  think I have 3 bags of organic compost, and a half bag of mushroom compost.  I may mix in some native soil, but I have to be careful to not add to much because we have a lot of clay in our soil.  I hope this will be enough.  It's important to me to keep the cost down, and use organic. Two things that don't go hand in hand.  
Thanks again.  If anyone has suggestions, or input I'm always interested in learning something new, and I have one more hugel beet to make as soon as I'm done with this one.  Thanks happy gardening
