I recently came home from a trip to find my friend who was in charge of watering my plants while I was away over watered my Hawarthia that I have had for years, it was one of my oldest plants and beautiful so I don't want to lose it. Is there a way I can propagate with cuttings that don't have roots? Most of the roots rotted but it luckily did not spread to the leaves of the plant, I couldn't save any roots on most of the cuttings I was able to get, and the ones that do have them are very small and weak looking.
Please tell me if anyone knows a way to save my plant? I will be very sad to lose this one if not ):
Thanks.

Best bet is to cover the cut part with cinnamon, let it callous, and place it in soil. Dont know how well it works, , for me 6 out of 11 attempts were successful(but mostly with aloe, not haworthia/haworthopsis)

Welcome!

Are you trying to root a single leaf? Or a rosette? Maybe a photo will help.

If there is no rot in the stem, you should be good to go. Get rid of the old soil and bleach the container if you want to use it again with this plant. Or find a pot that's wider than deep, with holes at the bottom, that's just a bit bigger than the rosette. Use soil for cacti (bagged cactus mix) or use regular potting soil mixed with an equal volume of pumice, perlite, or equivalent. Put the cutting on top of the soil without burying any leaves and with very little stem buried. Put the pot in bright light (indoors that would be by a sunny windowsill) and wait a week to water. Then water well and from there on out only water when the soil is dry at depth (not just the very top layer). This will depend on light and temperature and humidity, since evaporation is the only way the water will leave the container until the plant starts drinking. When you see new growth on top you have a very good indicator that the roots have sprouted and are working.

Why Cinnamon? I don't think I have ever heard of that.
Thanks for the advice.

Thank you for this very informative answer, this is very helpful and I'm hopeful this info will help me save my plant.

Cinnamon is a natural fungicide and, if parts of a plant are rotting (I've also used it to kill the roots of those annoying yellow mushrooms that grow in potting soil), that would do the trick. But, cactus and succulents don't play by the same rules. Simply removing rot and letting the pieces air dry will be of more benefit that treating with cinnamon.

Prepare a seed tray of compost a bit on the gritty side. Peat & verniculate is good. or a peaty compost and sharp sand. Soak it and let it drain. Now select/salvage leaves or stem parts. Cut away and discard rotted portions. Select and cut into portions of about 1.5 inches. Gently press the cutting into the compost. If you are using a propagator cove but leave the vents open. In hot sunlit areas, a bit of shading will prevent th compost drying out. Soon yo will have rooted cuttings.
