Cereus forbesii or aethiops maybe?

[Grafting a fast large growing cactus on a small slow growing root?]

I know this blog and like it very much. I already jumped the bandwagon and bought seeds from a western texas Lophophora variety.

Apparently the winter temperatures are not a problem for them outdoors in germany, but without protection the tap roots would rot in the cold and humid weather I'm sure.

But with the root of a Opuntia fragilis or similar, grafted hypocotyl style. When planted making sure to keep the Lopho part half a cm above the soil line, supported with rocks... who knows, might work.

Gotta get some stocks.

[Fertilizer for Acacia maidenii?]

Very helpfull, thank you!

When i planted I gave them rhizobium by mixing in soil from a native legume, hoping they are symbiotic. the soil is a mix from this old potting soil, grit and loam, drains easy.

The pot is about 40 cm high, I hoped its enough depth for the roots to grow the plants to a high of about one meter.

If they are allready rootbound i might really have to try bonsai, winter is to cold and to wet here to plant them in the ground I believe.

I plan to put them in big containers at some point, but this might take one or two years, I hope to keep them alive till then.

I'll try a carefull dose of 3-2-3 tonight, I hope they like some P.

I did not know that phosphorous is toxic to so many Australien plants, maybe this is how I lost my eucalyptus seedlings.

[If a loph self-pollinates, will seeds give clones?]

Higher Plants are diploide (polyploide sometimes), having a maternal and a paternal set of chromosomes.

Self fertile Lophophora are highly inbreed with very low genetic diversity. The selfed seeds from these plants are almost clones of the mother.

If the diploid plant has the chromosomes AA/BB/CC... ect ( 11 pairs, 22 chromosomes in total I think ), the haploid egg cells and pollen will both have chromosomes A/B/C...

The resulting diploid seeds will again be AA/BB/CC...

In plants with a broader genetical spectrum like a F1 hybrid potato the chromosome pairs might be Aa/Bb/Cc.... In meiosis the chromosom pairs get divided and one of the two copies goes into the egg cell or pollen. Egg cell and pollen have a haploid chromosome set like A/b/C... or a/b/C... or a/B/c... or A/B/c... ect.

The resulting seeds from a selfing could be any combination possible: aa/Bb/CC..., AA/Bb/Cc..., Aa/bb/Cc.....

So generally you don't get clones of the mother in a self polination. You get a new combination of the mothers genome. Sometimes a chromosome of the pair will not be passed on to the next generation, the other one from this pair will be passed double.

But if maternal chromosomes and paternal chromosomes from those pairs are identical, you will get genetically nearly identical seedlings.

[Fertilizer for Acacia maidenii?]

I have two maidenii seedlings growing in a pot since 3 years.

They grow a bit slow and the foliage stays rather small.

I think the main problem is the short grow season here, but i wonder if I could help them with some ferts?

Its my first Australian native plant, I'm not sure how much i should give them. I guess only a little dose?

low nitrogen?

[Grafting a fast large growing cactus on a small slow growing root?]

jwerta the wet feet tollerant species question was already a new project, I'm was a bit erratic there, sorry.

This seedling root grafting technique opens totaly new perspectives for me!

I think Trichocereus stems would freeze here in winter even if the root could survive it.

Lophophora on the other hand could be covert with leafs or something and keept outdoors on wet tollerant roots. Maybe.

Bennys site is great, very helpfull, cheers!

There is a long list of potential Opuntia stocks.

Going to try get my hands on some seeds or cuttings.

[SUPERPEDROXJ3]

I have a peruvianus plant I think is variegated.

When it first started it looked very much like the blotches on the plant above.

It was grafted on Periskiopsis then, before the seedling looked normal.

[Grafting a fast large growing cactus on a small slow growing root?]

Thank you for your input!

This seedling roots/top swapping looks excelent. I did a swap with 4 Lophophora and Trichocereus seedlings last night. Unfortunatly I was not using anything to hold the scions down, this was a mistake. The Lopho tops on the Tricho roots are looking good, but two of the Tricho tops have fallen off allready.

I try to save them, but I think i have to redo the operation with more care this weekend. When success and camera i shall post pictures of them.

Auxin, your idea with early flowering Echinopsis is probably a good one. I think I better find something that is not growing much pups. I was thinking more tiny, like Turbinicarpus-tiny but faster, but I don't realy think that will work. The Tricho scion would put out own roots when it get restricted from the stock I imagine. I want to try anyway. Grafting to a cold and wet tolerant Opuntia root looks like a good idea, too. For german winters outdoor. O. fragilis or O. phaeacantha are saied to be cold and wet tollerant. Are there any other cactus you know that can deal with wet soil and freezing temperatures?

I'm not having to high hopes in all of this, I imagine this has all been tryed before, and I don't see fancy cactus in front gardens here.

[Grafting a fast large growing cactus on a small slow growing root?]

Dont think it will look like a bonsai though.

Meh, naysayer . I'm not too optimistic neither, especially on the mini flowers...but

I put a Trichocereus seedling on Mammillaria gracilis pup. Lets see

[Grafting a fast large growing cactus on a small slow growing root?]

I wonder some time now. Could a Trichocereus be grafted on a root stock like Lophophora or Mammillara to produce a bonsai on the window sil with mature appearance, maybe even mini flowers?

I'm about to try it with a Mammillaria, but even if this works I see a problem that the Trichocereus will root on its own after some time.

Do you know if this has been done before? Also if you have any recommendations about easy, hardy and steady but small growing species I could use as root stock please tell me.

[How to straighten up a crooked cactus?]

Is it a columnar cactus? If its only 9 cm by now you can easily hide the crook under the soil when it has grown some more.

[Edimia ????? What is it?]

i think its Apocynaceae like Plumera, but i don't know wich one eighter. looks similar than Catharanthus minus the pistil sticking out. Nerium flower does have that, but doesn't match eighter.

[Looking for psychotria in europe]

Hi!

I'm looking for a Psychotria viridis or cartagenensis leave cutting ( preferable domestc ) or seeds.

I have cactus seeds and other plants to trade, or I could pay you for it ( well, next month, I'm broke now...)

Thank you all, good gardening!

[Trichocereus]

Nice plant. I was thinking pachanoi, but I'm not familar with hybrid traits. Do super pedro or lance grow V-dents like this?

[Learn from other Peoples mistakes]

If you store your cacti cool, dry and dark in winter, remember to give some water to younger plants that are not as well established and can't store as much water. i killed all my 1,5 year old seedlings this winter neglecting them.

Just had to google the english term for what i meant. Crispers. Took them out the fridge and potted two giant cacti in them because i thought it would be a great idea. I think "temporary insanity" is the word that fits best.

 

I have seen some Echinopsis planted in a crisper at a botanical garden plant sale two weekends ago. I was thinking its a brilliant idea, looked neat. Were these your plants or is this becoming a trend?

[ID Help]

Hi Ryan. Plant 10 looks like a variegated Ficus benjamina and I think plant two belongs to the dogbane family. Thats all I know. The first plant looks great, I have never seen one like it. Is it a conifer?

[button cactus for sale]

This is an amazing plant! I think 350 is a great prize, where I'm from Lophs seems cheaper in general and I think here it would cost that much in euro at least.

I suspect under the heads there is plant body from older grow going rooty. Is it?

[What did you do to your cacti today?]

They are on my balcony. It has a roof and walls all around except to the south, the walls buffers the night cold a bit. I had left a pot with bridgesii plants outside for about a week, they had night temps around 3° and it looks like it didn't hurt them. Now it is getting warmer here and I decided that spring has started and it won't freeze anymore...I might have been a bit optimistic about that. I'll monitor night temps and if it is getting colder than 3°C again I will have to evacuate them to the living room. My gf will love it...

[What did you do to your cacti today?]

In Germany it was 17° today and I brought the collection out. I found non of my T.glaucus seedlings had survived the winter in the cellar. I going to plant some new seeds now to calm me down.

[Perfect Datura Administration]

Is that sarcasm Psylo?

 

Its indeed true people accused saied 'whitches' doing these practices. The medieval version of shock horror porn. There are many illustrations.

I have heared of the use of datura with other plant in very very very low quantity ( in this case 1 seed Datura stramonium). it is used against sickness induced by saied other plants, and it make sence to me, I know there are plasters against motion sickness with scopolamin as active ingrediet
