Old tubercles always die but the care matters. That greenhouse is quite shaded, at about 50% or more. Also Leuchtenbergia in culture are in two different varieties that have different body colors and maybe tubercles' longevity. Fleshy roots store juices in a dry period so aboveground parts can dry o...

Hey, sorry for the delay in reply. Mammillaria tetrancistra and dioica. JT is smack dab in tetrancistra's range, which extends north up through Death Valley almost into the White Mountains. JT is a little north for dioica--which is more often seen a little to the south in Anza Borrega or on the coa...

Somebody knows about Neoporteria cachytaensis?

It depends on your climate and also on species you grow. I prefer graduate increase of watering in the spring, because weather here is cool with sudden changes. Some of my home plants have being watered the whole winter with bigger intervals and some get water just starting in May.

The spring is here finally, https://live.staticflickr.com/65535/53635720933_5fdc794e23_b.jpg Matucana aureiflora. https://live.staticflickr.com/65535/53635958495_8b13765652_b.jpg First buds and flowers for these Notocactus submammulosus, my seedlings. https://live.staticflickr.com/65535/53635718848_...

I forgot what this one is called

Eriosyce bulbocalyx. I love it!

The 8 photo must be opuntia cochenillifera, is it?

I guess so if it is not another Nopalea...

Yes, they were all greenish hummingburds and not all visitors spotted them.

George Do you know the species names for the Mammilaria and the Ferocactus? Great pictures!! Thanks Hagai Mammillaria dioica & Ferocactus cylindraceus. My theory is that aside from the sun shelter cacti growing next to rocks get more water because rainwater falling on that rock drains to the so...

Birds and turtles were an extra view in the garden. Find the nesting birds in next two photos.

Being in Palm Springs I visited this garden last month. Lot of plants, hard to judge how many species. Will show you some of the photos I've taken there. https://live.staticflickr.com/65535/53635884714_3de1f5ed74_b.jpg https://live.staticflickr.com/65535/53635756878_2f6be54306_b.jpg https://live.sta...

It is true. Sowing is worth just for doing seedlings, that can be given away, sold, or grafted. Some or many of my 10+ y. old seedlings are still not mature and this winter I was tempted again to sow some of my harvested seeds...
