Discussion in 'Cacti and Succulents' started by Zigs, Aug 14, 2017.
Sowed 100 mixed cacti and succulent seeds. At least one has come up
Have any more come up? Ideally you should cover the soil with a layer of grit. Helps support the seedlings as they germinate
Left it a bit late Zigs.
Have you tried germinating cactus seed in an inert medium such as perlite ? If you've access to a heated propagator , fill pots with pure perlite , cover seeds with about 1/4" of the same ; STAND POTS IN WATER UNTIL SEED GERMINATES ; this goes against current advice , but when I worked at Whitestone Gardens years ago , this was the virtually guaranteed way to grow seedlings . A constant supply of water is essential ; hydroponic cultivation was the norm ; reduces the risk of bacterial and fungal infections . Mature plants were only grown in a 1/11 mix (1 coarse sand & 11 parts grit ), and fed with liquid nutrients . Such gems as Aztekium , Ariocarpus and Copiapoa were grown well using this method . Forget any idea that cacti 'thrive on neglect' ; moisture throughout their growing season is vital as well as copious feeding with low nitrogen fertiliser .
Cheers all, will try that
Hi Paul, May I ask, what height of water are you talking about, just the depth of a pots saucer or much further up the pot, say 1/4 or 1/2 way up ? thanks
Hello Ricky101 The pots (about 5 inches diameter) were kept in neutral pH water to a depth of about 1 inch . They were in heated propagators in a partially shaded large greenhouse ; optimal temperature around 21-25 centigrade . Maybe better in spring with better light conditions .
@PaulB3 really enjoying reading the info and learning about succulents on this thread
Hi Paul, Tried your method and so far its really worked a treat, see Living Stones/Linthops / Succulents Many thanks
