They should have grow some roots by now...BUT not if kept in constantly moist soil IMO. Succulents without roots will rot easily if kept wet...

ok i'll try that ty

I rooted many, and usually they root within 10 days-2 weeks. It could take bit longer, but not 5 +weeks IMO. I just stuck few short cuttings here about 3-4weeks ago, they are already rooted, and there is also new growth :

You may have it in a cold place. They love bottom heat to take root fast.

I break off the little round leaves and root those. One good way of doing it is to use a small plastic, such as a condemint container, with an inch or less of soil or even clean sand. Use a spray bottle to moisten the soil every few days. Try not to swamp the soil.
