Thank you Steve, Elie and Dave,

Good I will look for a 1-1-1 ratio fertilizer with micronutrients. I have a 18-18-21 tomato fertilizer with micronutrients that I could use at 1/3 or 1/4 strength ?

If I have other questions after reading Steve's post I will let you know.

Have a good day !

Hello, I am on my way to switch to an almost 100% mineral mix and have a question. When growing season will come, somebody really into bonsai told me to use a 3-1-2 ratio fertilizer (ex. 24-8-16) to 1/8 strength every time I water. It sounds logical to me, but can it be applied to cacti too ? What d...

M. zeilmaniana on steroids I bought from a hardware store =
The same M. zeilmaniana 4 months later, enjoying full sun =

Ok temp is actually around 29 C (84 f) during the day and 24 C (77 f) during the night. I will rise it a little bit like you suggest. No rot for now. They will be 3 months old in 2 weeks, they start to look more like their parents now !

Thank you.
Is there a way to prevent rot while leaving them in the baggy ?

Hello, I started some seeds of Coryphantha vivipara and Echinocereus engelmannii almost 2 months ago. I used seedling trays in the baggy method. Since then I had to open the baggy every 2-3 weeks to add a little bit of boiled rain water because the surface of the mix (50% seedlings potting mix and 5...

Thanks George ! Yes, all the fruits from the hundreds of live engelmanniis that I found were already eaten by rodents/birds. I was there for a week in September and the only seeds I found of this specie were on that dark cacti. At least it did not die in vain ... His descendants will grow 4600 kilom...

Hello, I collected seeds from this E. engelmannii near Phoenix, AZ. Most specimens were ''yellow'', but this one was really dark. I cannot say if it was dead or alive. What do you think ? Is there a var. something that looks like this ? Anyway the seeds were viable and the seedlings are 3 weeks old ...

there might be lot of other reasons aside of "not getting enough cold" for this like: small size, fighting some disease, getting not enough sun previous season, luck of some nutrients (P) and so on. This is true, but my cacti are pests free since a year (I am crossing my fingers while say...

For the last winters I used to leave my plants on the windowsill and reduce watering to a minimum, maybe once a month between November and march. Temperature was around 62 to 75 F (17-23 C) on the windowsill. It was not perfect, but it worked except that only mammilarias flowered during spring and s...

Thank you ! I can't wait to sow them ! It will be my first try from seeds, I just bought a heatmat, a thermostat and a 24'' T5 fixture.

Hello,

Last month I collected some seeds from what think is Coryphantha vivipara.

Location = around Sedona, AZ

Elevation = 5600'

Can somebody confirm ?

Thanks

Hello, The greenhouse I plan to buy comes in 3 models = - Clear polycarbonate panels - Twin wall 4 mm polycarbonate - Hybrid, clear for the walls and twin wall for the roof. At first I tought the clear panels, 90 % light transmission, was the best choice for cacti. But the manufacturer states that t...

Can you tell me the ID of the purple sulcorebutia on the very left of picture 172458.

A friend gave me an offset this spring and I could not ID it, but it looks exactly like it !

Wow, thanks for sharing !
As a Canadian it is really interesting to see there is some hope regarding species we can try to grow outside year round !

By the way nice pictures, can't wait for your next trip to see more !
