Aloinopsis rubrolineata from seed
Aloinopsis rubrolineata from seed
Hello. I had some Aloinopsis rubrolineata seed germinating and they all suddenly keeled over and died. I have them growing in a mixture of cactus mix with added pumice in a ziplock bag. All the seeds I planted germinated, but then they all just fell over and withered away. Any suggestions? Thanks in advance!

Probably damping off. Was the soil mixture sterilized?
Re: Aloinopsis rubrolineata from seed
What does damping off mean? I don’t have a microwave so I used hydrogen peroxide and a fungicide.
Re: Aloinopsis rubrolineata from seed
They can be a bit hard at first, sowed them twice, got some plants, but many seedlings didn't make it. But ziplock sowing requires sterilisation, which can also be done in a cooking pot, if you use containers instead of bags, preferably a pressure cooker. I've done it before and I'm temped to say, worked even better than in a microwave With me the hardest part was when opening the containers for the first time, and some seedlings started dropping, leaving me wondering if it's because they were too dry...or too wet...still not sure.

Hmm. I do have some more seeds. I’m going to give it another try.Jangaudi wrote: ↑Thu May 05, 2022 8:21 am They can be a bit hard at first, sowed them twice, got some plants, but many seedlings didn't make it.

Do you mean you put the whole container with soil in a pressure cooker?
Re: Aloinopsis rubrolineata from seed
Pretty much so yeah, with moist soil inside, ready to sow, same as if I would put it in the microwave, with a lid on it, but not turned on, otherwise you risk pieces I have one of these bamboo steam plates that I put in the pot first, so the glass doesn't start banging on the bottom of the pot when it's bioling. I use glass jars, but I guess some heat resistant plastics could also do the trick. And probably best wait to sow till after the summer. they are sort of cool germinators as far as I remember.
Re: Aloinopsis rubrolineata from seed
Oh good to know. Thank you. It stays pretty cool where I live most of the year haha. I have them on a heat mat too. Would it be better to leave them off?Jangaudi wrote: ↑Thu May 05, 2022 1:46 pmPretty much so yeah, with moist soil inside, ready to sow, same as if I would put it in the microwave, with a lid on it, but not turned on, otherwise you risk pieces I have one of these bamboo steam plates that I put in the pot first, so the glass doesn't start banging on the bottom of the pot when it's bioling.

Re: Aloinopsis rubrolineata from seed
hmm, I saw someone saying germination temp. between 18 and 28°C, and somewhere else, during summer, when it's warm, altough they are considered winter growers. Seems they are not too picky about temperatures, I think you're good to go

Great. Thanks for the help!

Re: Aloinopsis rubrolineata from seed
To sterilize the mix, you could always pour boiling water on it. More effective than hydrogen peroxide IMO.
