Are you giving your plants any water now that they are budding? I'm thinking you are not. You're right, they are kept dry. For me, these will flower late February to early March, but I won't water until after they are done flowering when night temps are more predictably around 50F, mid- to late Mar...

All of the seedlings look great, but I particularly like E. napina and F. chiquitana youngsters. :thumbup: Cleistogamous Fraileas do flower occasionally, but they need very hot weather and full sun. My F. angelesii flowered this summer (beautiful pale pastel yellow flower), but F. grahliana and F. ...

Here is the first part of the ADBLPS cactus seeds I sowed January 2023. Instead of giving the seedlings a cold winter rest, I've kept them growing inside the heated propagator box all year. I originally sowed the seeds in small disposable shot glasses and repotted the seedlings into larger pots in O...

T. pseudopectinatus and T. valdezianus are producing flower buds despite being very cold (nighttime temperatures as low as -6C/21F, daytime barely above freezing). It's always astonishing how adaptable these plants are. I am quite sure it doesn't get that cold in habitat (a quick search says around...

Instead of making a new thread for every year I sow seeds, I decided to just post future sowings here (I'll keep the 2022 thread I made active for that sowing). Here's the first part of the 2023 sowing: The setup and procedure is much as described here: https://cactiguide.com/forum/viewtopic.php?t=4...

It's rainy in the winter here but most winter repots make it out ok. I did kill a few plants last year from watering too soon after repotting in the winter though. Frailea, I noticed, seem to be sensitive to repotting when dormant. I pulled two species out of their pots last winter and within a few ...

If I remember correctly, only 2 seeds didn't germinate from the pot shown. I didn't bother looking for them.

Have you tried following this advice: https://www.youtube.com/watch?v=MGG2-YpGDWA ? Works like a charm, at least for Sclerocactus. I skipped the sterilisation part myself as I see more use in the effort of sterilising the soil I sow the seeds in. Yeah, that's the video I followed. The seeds I didn'...

I've read at least twice that Echinocactus [/i] and Homalocephala [/i] are easier to coax into germination by using it as a means of scarification prior to applying water (soaking in acid overnight). I have not used it, as my current treatment (high temps.) have worked well. Ah yes, I nearly forgot...

Some flowering Conophytum from earlier in the fall. Conophytum hermarium Areb, Northern Cape, RSA. Mesa Garden has this as C. smorenskaduense subsp. hermarium. https://imgur.com/CcVP7dx.jpg Detail of the leaves https://imgur.com/7x3lzHm.jpg Conophytum pellucidum 'terricolor'. https://imgur.com/zmJU0...

Pediocactus and Sclerocactus would probably benefit. Opuntioid seeds would be good candidates too.

I once found a couple Astrophytum myriostigma seeds that germinated within their seed pod.

Britton and Rose observed this behavior in Selenicereus grandiflorus fruit.
From their book The Cactaceae:

Cochemiea theresae those are hard to germinate ( for me anyway ) well done . These germinated no problem within a few days of sowing. I sowed another batch in November and those have yet to do anything. :lol: Cochemiea theresae are my favorite cacti. I tried nicking the seeds which did accelerate t...

I haven't sowed the cactus seeds for this recent order yet, but I did sow the winter growing succulents a week ago. For the Pelargonium, all but one seed of one species has germinated. The others have just started to germinate with the exception of Aloe polyphylla (not really a winter grower but inc...
