Re: Is Lophophora cultivation legal in USA?

Surprised if the Native American Church can use it other churches have not brought a case of religious discrimination that they are not allowed to?

Re: Bottom water top water your cacti question?

I once made a remark to a speaker who advised bottom watering for a certain genus that "it doesn't rain upwards in S. America. :D Really it can depend whether you are an ardent shower or just a general collector. Some of the shows people tend to water from below since it does not remove the woo...

Re: Prune or trim roots Question?

As with garden plants they used to advocate trimming any broken root ends since a clean cut straight across exposed less tissue to pathogens than a ragged tear. However unless it is to fit it into a container there is no real point in cutting healthy roots. If you do trim allow time for roots to hea...

Re: Rebutia heliosa Theresae?

Cacti flowers can be beautiful but some can have very tiny insignificant flowers and also some very big ones according to the genus. Epithelantha bokei, with tiny whitish/yellow insignificant flower in the centre. The fruits are much larger and more spectacular than the flowers. Epithelantha-bokei.j...

British Show Rules

Cactus & Succulent shows around the world work to different rules and have different styles of judging. Therefore you may be interested to read how British rules set by the British Cactus & Succulent Society differ from yours? One difference is as long as the pot is clean and undamaged it do...

Re: Rebutia neocumingii / Weingartia ???

I for one do agree with combining Weingartia and Sulcorebutia since they do not belong in Hunt's "Lumped" Rebutia. Hunt's classification was based on morphology not DNA Sequencing which has shown many of Hunt's "Lumped" genera are polyphyletic (= " a group of organisms) deri...

Re: What makes crested/monstrose cacti?

Fasciation (note not fascination = no "N") meaning cristates and monstrous plants is caused by an upset in the cells at the growing points. With monstrose cacti there are obviously latent growing points at every areole which is why we get offsetting, but in monstoose cacti they are trigger...

Re: Winter barometer?

Some of the Other Succulents reverse their growing season in cultivation and grow and flower in our winters. However with cacti they tend to broadly follow the same growing season as do the other native plants in your area. When the deciduous trees start dropping their leaves it is time for cacti to...

Re: Hardest species to grow?

May depend not only on the countries overall climate, but on microclimates. If you have more than one greenhouse a plant may grow well in one but sulk in another. Also a different position in a greenhouse whether down on the staging's or high up on a top shelf, full sun or partial shade.

Re: Excess Plants

America is a more scattered community than in Britain, so probably not appropriate due to distance, but here I would give them to a Charity Shop if nobody else I knew wanted them. However our club does often attend local shows for other societies and no doubt one of their stalls would dispose of the...

Re: Most popular cactus sold?

Yes, conditions dictate popularity. The Brits tend to grow smaller species that take up less room in a heated greenhouse rather than taller Cerei or big Opuntia's which more of us would do if we could grow them outside all year.

Re: Columnars and little one

The generic name "Xiquexique" was new to me, but evidently was validly published. "Lavor, P., Versieux, L.M. & Calvente, A. 2020. Phylogenetic Relationships of Pilosocereus (Cactaceae) and Taxonomic Implications. PlantNow 1(2): 52–70." Seemingly Xiquexique was erected as a ge...
