| subject Growing plantlets. |

I've been growing numerous generations of the mother of thousands plant since 1991. I just planted a seedling there on the 15th and to date, I have not seen any growth and the plant it's self has not seemed to root although the plantlet it's self looks healthy. Maybe I am just being impatient, but I do not remember the plants progress being this slow.
My question is this: What is the upper limit to wait before you begin to see growth in the seedlings? |

I experienced this several times too.
I don't know what's going wrong, but maybe the soil is too moist or too dry. I'd try another plantlet(s) and if that doesn't work, change the soil. Maybe you got bad soil.
Cheers,
Captain. |

Thanks Captin!
Could it be anything to do with the climate I live in? (Glasgow, Scotland) It is still relatively cool here, although there has been plenty of sunlight getting to them. |

| Yes, sure. The climate might also contribute to slow growing plantlets. I had best results when it had >20C outside in direct sun. |

| One thing that seems to have worked on one of my plantlets has been to breathe on it at night and cover the pot in clingfilm to seal in the higher concentration of CO2 and leave it overnight. I have done this for 3 nights now and the plant seems to have doubled in size in comparison to the others. |

Interesting experiment, Mick! But I think rather the clingfilm (small greenhouse) is the reason for the increased growth, than the additional CO2. What is your current minimum temperature at night ?
In Austria we still have freezing temperatures at night, so all my Bryophyllums are still inside. But as usual I will start over again, since all plants etoliated over the winter (I have 2 lamps, but that is not enough light), so I think I will put some plantlets into soil mid-April or so. |

Here, the temprature is still cold enough for ground frost in March. Unfortunately, it is never hot enough here for bryophyllum to be planted out doors.
The reason for doing this experiment was that I only just found out that bryophyllum was a CAM plant and increasing CO2 levels can make plants grow faster. So perhaps it's a combination of both! |

Here is a website showing the correlation between CAM plants CO2 concentration increases:

Way cool! Thanks for the info and the link!
I will try that by putting some plantlets into a transparent plastic bag and inflate it with the CO2 of a soda bottle cartridge. As a control group I will put some other plantlets also into a transparent bag, but without adding CO2. I keep you posted! Thanks again! |

| Hey Captain, had any luck with your experiment? |
