If they slow down growth then you know it's time for a bigger pot. I would grow them to the one gallon size then plant them, or put one in the ground next spring and see how it does.

How long did they take to sprout?

Maybe with luck and time it will look like this. 😉

Andy, did you get the seeds from koehres-kaktus? I had no problem germinating yccas, agaves and hesperaloe this year (a first try in February, a second one - in June).

Igor... I got my seeds from http://www.sunshine-seeds.de/Seeds-A-Z-Y-126_1015c.html?iosCid=a5ebe165c1c6d3b15b62d0b24290d08a
I think it was due to the terrible spring/summer we had that they didn't germinate. Could also be a possibility that some species need Stratification??
Thanks for the head up... I will have a look on their website

Aaron... That is one testosterone charged plant 8) Shame that I would be bone meal before mine got to that size 😉 Any idea what lows it can take. The problem in the UK is that we don't get the baking heat but we can get the freezing cold but maybe not as cold as you 😆

I'm not sure how much cold they can take, the pic was taken after a winter low of 1F(normal is zone 8b). I have yet too see one make it through a winter in Idaho. 😕

Grew my Schotii last winter and they grew fast in 4" pots, I planted out one of them (2 plants in a pot) in to the garden in March and they are growing slowly now, but doing way better than Yucca toreii that germinated about the same time. I up-potted the others of schotii to 6" pots at the same time and they are doing equally as well as those planted out, it not better. My experience with most yuccas, is that they do the very best if planted directly from plug to 10" pot, where it can get strong deep roots for about two years... then get planted out. But I rarely do this, cuz I am impatient and cannot fit 50-some odd 10" pots on to one grower cart shelf like 6" pots do.

Hi Adam,

I have not had much success with young Y. schottii. It seems the trunk diameter needs to be greater than 3/4" (2cm) or they will likely die in winter. Excess moisture in combination with winter cold seems to be the biggest problem. If you keep them dry-ish is winter they may survive long periods.

I'm going on a mission next year to Arizona, and I going to try and get some high mountain schottii seed. 😉

which mountain tops? I was on top of Mt. Lemmon back in 2006 and none of the schottii's were in bloom or had seed. I didn't even see old bloom stalks.......strange. I only stayed along the main road and it appeared schottii stopped at 7,500ft or so. I'm sure they are higher but we didn't look that hard since the family is not into plants/yuccas.

That is about as high as you can find them. I saw some nice sized ones high in the Chiricahua's.

Same thing I went through, my wife was not into waiting in the hot car while I went on hikes. 😆 So I hope too find some high mountain seed next year. I think I will head out in the last part of sept or first week in Oct of next year. Of cource everything changes in a year.
