Newbee to Haworthia, Aloe and Gasteria

Post by dazzy2000 » Sun Apr 28, 2019 12:34 pm

Hi
i have just recieved my seeds for the Haworthia Society and i would like to say a massive thank you to Les for the great communication and the fast delivery that they were recieved.

I'm already a member of the BCSS society and will be joining the Haworthia society very shortly. i have raised many cactus from seed and doing very well but wondered if the Haworthia, Aloe and Gasteria needed different growing techniques as i would hate to ruin the seeds i have been given.

I hear that Haworthia don't need as much heat to germinate and if it is too high this could affect the germination rate. does any one have any tips on seed raising regarding temperature, soil mixes and general care. I have a south facing window and thought the seeds would be fine in this position but will get full sun during the day and cooler at night.

Thank you
Darren

There's not much difference though I'd push the seeds vertically half way down rather than leave them on the surface like cacti. it doesn't matter which way up, they'll sort themselves out.

I’m not so sure about having freshly germinated seedlings in full sun all day in a south facing windowsill, but perhaps those with more experience can comment further.

hi Darren, I'd say watch the sun! I lost a lot of newly germinated Haworthia seedlings last year when we had some hot weather early in the year. Like you I had them in a South facing window but in a bathroom. I don't think ventilation was the problem so put the losses down to sunstroke.

The ones I've just set for this year won't get direct sun so I'm hoping they'll fare a bit better. Good luck.
Cheers
Gary

I completely agree - keep them cool and shaded for a year and longer, and even with adult plants be very selective which species you expose to prolonged sunshine as not all will take this.

This is a good website to have a look at: http://haworthia-gasteria.blogspot.com/ It gives information on species, some advice on cultivation and lots and lots of habitat pictures.

Thank you for all the great advice. Think I will be putting in a cooler room or lower down in the greenhouse where it is cooler and less direct sun. Is this the case for aloe and gasteria or can they take more heat.

Personally, I'd keep them all out of direct sun, and for Haworthia and Gasteria I'd aim for temperatures below 20C. Is it Aloe comosa you are trying to grow? That is the one on the Haw Soc seed list. With such a large genus and optimum conditions for germination will vary - no idea how best to grow that one on...

Hi christian

i notice you are a member of the Birmingham BCSS. i live in Stourbridge and wonder how do you join or where do you have meetings as i'm hooked on Cactus and Succulent and need more to feed my addiction.
thanks
