Thats usually a hoax,you'll just waste seeds. It didnt work with mango, it didnt work with persimmon etc. even it does germinate youll probably damage the roots during moving to soil medium(like the papaya seeds that did germinate, except the allready potted ones did a lot better anyway). Get a lot of coarse sand , mix with perlite and peat, (sterilize) and youre good to go. I use plastic food trays with lids, but you could use Ziploc if you can.

Just introduces an additional pointless step into the process.

I wouldn't recommend it for lithops seeds. I've used that method in the past for adenium and pachypodium seeds with success, but as stated it's unnecessary.

I did this once 4-5 years ago, following whatever guidelines I read. (See photo below.) I'm not sure why. It's hard not to lose some in the process. Just imagine having to transplant these little things into very porous soil. Even if transplanting when they're older, the roots are entwined in that stuff.

They germinate pretty quickly and easily, and they aren't very difficult to see, so I don't think there is any advantage. I just sowed some in mostly pumice for the first time and it's working well so far.

Why wouldn't you just cut the piece of paper towel and plant it that way? Kind of how they use the peat plugs in industrial plant prodiction.

I don't think planting all of them on one (cut) piece of a paper towel would work very well at that point. Or if you mean cutting around each seedling, that would be even more difficult. I don't know if paper towel dissolves or not; I can't remember the process. However I did it, I lost some in the process, unnecessarily.

I have links if needed for more guidance.

Thanks everyone for your input. I start tomatoes and peppers like this and was just curious if it could work with lithops/succulents. But the consensus seems to be no/no advantage. I was thinking that would be the case

Jeff, sure, if it's not too much trouble, I could always use more reading.

AS_NJ, does the paper towel disintegrate, or do you transfer from it? Not asking to critique, just curious. I'm also sowing some (hot) peppers this year.

Here are some web sites:

PT should disintegrate but if you're concerned it won't, single ply TP definitely would.

Sorry for late reply!

Jeff- thank you for those links. One of them had good information on where to buy seeds so I actually bought a bunch and they are slowly but surely growing now.

When I have used the paper towel method I took the seedlings and transplanted into soil.

Bernard- my seedling pots now all have some that have germinated. I haven’t been using plastic baggy method but I’ve been spraying every day. Hopefully that’s ok :x. I’m not sure when is a good time to put them in front of the window for some sunlight now that they have germinated?
