Re: Let's grow some Melocactus!

Hi @madkaktus. Wow, this is nice to get off of Facebook for a little while :D Many years ago, I bought 2 large relatively cheap Melocacti from somewhere like Homebase, with fully formed cephalia. I repotted them, and they faded away somehow. I can hardly remember what happened. I think one rotted an...

Re: Let's grow some Melocactus!

@madkactus Whenever the subject of Melocacti comes up I'm always banging on about my 30 year old M. violaceus that I've kept bone dry for 6 months every winter, every single year since I got it as 3cm plant. About 3 years ago it grew its cephalium. It gets winter minimums of 5-7°C. With plants as su...

Re: Cactus in trouble

Yes, Harald is right, it is a Euphorbia. Basically, all that advice is sound. The most important thing now is that you unpot it and cut off all rotten parts with a sharp knife, or one of those types of ground pruning saws that make razor sharp cuts. You need to cut a good inch or so beyond any signs...

Chempak fertiliser precipitate/insoluble component

Hi Folks, I use Chempak Cactus and Succulent Fertiliser. There is always something left undissolved in the water, even if I heat it up. Does anyone know what it is? I use rainwater or RO water, so the pH is always 5.5-6. I have not yet asked the manufacturers because from experience going to the &qu...

Re: Welwitschia mirabilis

This is a seedling that died. Interesting to see how it grows out of the seed. The seed is flattened side down.

Here's a pic of the set up with the 6 remaining seedlings out of 19 seeds, 10 of which were found to be already dead, and were not sown.

Re: Welwitschia mirabilis

I had one odd seed left, so I planted it in the middle of the pot with three planted together already, and within a week it has germinated. Just English autumn room temperatures.

Re: Welwitschia mirabilis

It has been a bit hard to find out, but I am pretty sure they are wild collected seed. They are from a German supplier - http://www.exot-nutz-zier.de/

I read that the wild collected seed which are infected with fungus are blackened, and will not germinate at all.

Re: Welwitschia mirabilis

A piece of information - according to the seeds I have grown recently, you can reckon on about 25% germinating and surviving. When you peel them, you find half of them are dead. Then about half of those left either fail to germinate, or they germinate then succumb to mortality.

Re: Welwitschia mirabilis

I've got 3 all in one pot now, they had the mycorrhiza treatment, now they are green and just starting to grow, I think they have passed the danger period. I seems to me that if you don't get germination within 2 weeks, they will not show themselves. Kristian, will you post pictures of your plants? ...

Re: San Pedro Seedlings turning brown!! (Pictures)

Why would you keep Echinopsis pachanoi in humid conditions? In the first photo they look very etiolated.
