yes, me too!
but this was the only letter I received from him. After that, we tried again twice but they never reached me, and we decided to stop trying, which is a pitty.

Just the first time. The other two tries I got it returned, along with a note from the Brazillian customs. At least they didn't destroy the seeds...

...which didn't happened to Elies' seeds: they just disappeared. Meanwhile, I keep receiving seeds from Europe and USA more or less regularly.

Concerning the seeds I've sent abroad, some reached their destiny, some didn't.

There is no pattern and it is a mistery to me.

Anyway, always when planning a seed swap, I warn people that such kind of thing can happen.

New batch, many thanks to the friends that sent me the seeds. Several cacti species, the so-dreamed Euphorbia obesa and leaf succulents such as Adeniuns, Fouquieria and Asclepias.

Mix to the cacti is composed of crushed brick (1/3), grit (6/13), charcoal (1/13), top soil (2/13), vermiculite (3/13).

Open pots, as always.

Here is the Table with species, number of seeds, days to first sprouting and number of seedlings after 30 days.

I always look forward to your updates. I see many of the seeds I sent on your list, which is neat for me. I'll let my seedlings know they have estranged siblings 5000 miles away.

The germination rates of the Ferocactus are interesting; here they grow like weeds. On the other hand, your rates of germination on the Astrophytums are much better than mine typically are.

Yes, Ken, I had better results for Fraileas, Astros and Sulcorebutias than for Ferocactus and Mammillarias, in general. Possibly this is due to the wheather: maybe too hot for some species.

But note that the number of seedlings after 30 days is different from the number of sprouted seedlings (which I have not recorded for this batch). Many things can happen within 30 days. Some Ferocactus such as glauscescens and robustus did have poor germination, but for other species I probably lost some seedlings.

I had this problem (viewtopic.php?f=24&t=39814). Leuchtenbergia was severely attacked. I'm sure that almost all seeds sprouted, but after 30 days only one remained.

Fortunatelly, this time I sowed only half of the seeds of each species. So I'll try another batch in autumn.

Thanks for following and, above all, thanks for all the seeds you sent.

Some update on my sowing experiences.
I have had too many loses due to dehydratation. Until now I have avoided the baggie method, but now I’m convinced that that’s the best way, so I’ll change my method.
Next I’ll show some pictures comparing seedlings grown in open and closed pots.
Parodia ottonis. Right, sown February 2018; left: sown in January 2017;. A year older, but not that bigger:
Image

Thelocactus setispinus: same day of sowing, same number of seeds; Left: closed pot; right: open pot:
Image

Frailea sp: same day of sowing, same number of seeds; Left: closed pot; right: open pot:
Image

In my next batch I’ll keep the pots closed, but for now I want to show some of my seedlings of the last batches. Most were kindly provided by Vipassana, others I picked up here and there.
Batch of Feb. 2017:
Mammillaria grahamii:

It's great to see such good progress. The Fouquieria are doing really well. Impressive.

I need to take some pictures of the seeds you sent me. I just planted second batchs of many of the seeds you sent and most doing well.

Re: So I decided to sow

It seems that finally I’ve learned with my errors and with the advices here, and decided to use the “bag method” (although I don’t use ziplocs; I use big containers instead).

Image

Seeds from the same plant, sowed in the same day, in the same substrate, but one remained in closed container. This kind of experiment really convinced me:

Image

Also, I’ve decided to try a pure grit mix, with absolutely no soil added.
The mix is composed of grit of several kinds of rock and crushed brick, sewed and washed to have only particles of adequate size. About 1/8 of the mix is composed of crushed charcoal, with I believe is a good component because of its water retention and aeration capacity.

Image

Image

The dry mix was cooked in the oven. Seeds were laid over the mix, and water was given from below. Water excess was taken out with and absorbent paper put at the bottom of the pots for a while. Pots were arranged inside the container, which was finally closed.

Image

Image

Low temperatures of autumn/winter here aided: at night, it drops to about 10 to 15C, and during the day it reaches about 25C, so seeds were in a good temperature range, I think.
I’m happy with the results, and I feeling more confident now.

Seeds from ADBLPS or kindly given by Armen and Vipassana.

Thank you for this extensive report. Differences you are showong are remarkable.
Soil you are using presently looks rich and I wonder how did you get all those gravel bits of pretty much the same size :lol:

Wow makes me want to try to sow seeds using a mineral mix now !

Can you describe what is in your mix ?

Did you add some fertilizer to the water ?

Did you have to spray the seedlings now and then ?

Thank you !

Thanks DodoBrooke for you interest. Indeed, this mix is the product of intensive labour...I almost give up sowing...
I have to sift through different sieves, keeping all fractions separately, and washing them to discard the smalest particles, leave drying. Them I choose the fractions to compose the mix.

Thank you J-M for your comments and questions. Note that I'm not a experienced grower, I'm still learning, thus this is not necessarily a recipe for success! This mix is composed by different grits and gravels, crushed brick and charcoal. The grits are from different rocks I find here, such as basalt, laterite, siltite, etc. Probably it is not that important to have all these kind of different rocks, but the different shapes contributes to form "micro-caves" of air within the mix. I dont use sand nor calcarous rocks. That's it....
I did not added any fertilizer in the water, but perhaps I'll do that when I open the pots (not before six months after sowing).
I dont spray the seedlings, as the pots are kept closed, so they don't loose humidity.
Good luck!

Same for me, I am no expert, but I like to experiment. Maybe this is how you can become one with time !

Good luck and keep posting your results.

So you'll let them stay in for 6 months?
I am wondering about mine, since I have sown for the first time and I picked bad period to sow-May and June. If I keep seedlings in for 6 months it will be middle of winter when I ll be opening the bag and I'm not sure if the conditions will be fine for them to adapt.
I still have to think about it :roll:
