Hello everyone,
I'am Edwin from Indonesia
But I moved to Thailand recently

I can speak english and french, so you are welcomed to speak to me in those language

I always am interested in cacti
When I was a boy, I had some cacti but I never knew how to take care of them properly
They died miserably
Now, since I have some spare time, I want to revive this old hobby of mine

Last week...I bought 2 seedling of A. fissuratus and A. retusus var. trigonus (although my trigonus seems to have a diedback-tubercule, the one with the yellow tip )

Nice to know you all

PS: do we have a WA (whatsapp) group?

EDIT: oops, I posted this in the wrong room. Please replace it accordingly. Sorry and thank you.

Welcome and good luck! From what I've seen lately Thailand is a great climate for cactus, if you can keep the excess rain away.

Ariocarpus generally lose a small number of old tubercles per year. They take a long time to dry out and die completely. As long as it doesn't spread you'll be fine.

If it gets worse you might want to take the plant out of the pot to check the conditions of the roots. Ariocarpus can be prone to rot.

Not sure what a whatsapp is, but perhaps someone who does will chime in.

Bienvenu!
A couple of members and i have a barely active whatsapp group (haven't talked for a few months now). If anyone would like to join we'd be very happy.

Not sure what a whatsapp is, but perhaps someone who does will chime in.

It's an instant messaging application on smart phones. You can have group chats and send photos and videos. Sort of like msn in the good olden days but for smartphones

Welcome and good luck!

Thanks Tim

Thanks for the info
It lose some tubercles in a way that the tubercle turns yellow from it's tip?

Also, would you know the answer to my question about the cactus hibernation in the tropic area?
Thanks

Bienvenu!

Merci

3) Ariocarpus retusus var. trigonus - it is doing well, it grows and the yellow tip stops spreading (thanks for the advice)

================================

My lithops. They just came in yesterday
I use 100% coarse silica sand for them, with tiny orange limestone for ornamental purpose
I see that they are sheding their old leafs, so i don't water them
I put them in direct morning sun from 8 to about 13 o'clock...

Check them out

I'am 80% sure that it is L. fulviceps, are you agree with me?

rsz_20200109_080723.jpg (76.62 KiB) Viewed 8937 times

And about 50% sure that this one is L. hookeri, is it?

rsz_20200109_080710.jpg (81.58 KiB) Viewed 8937 times

And....I have no idea of what this is...my guess is Lithops aucampiae "Jackson's jade"...any advice is appreciated

Why do you say the L. williamsii is sick? It looks fine to me. It's fully hydrated and a consistent color.

Not sure what the variation in day length is at ~15 degrees above the equator, but this is normally winter (shorter days) and most of these species aren't growing vigorously.

In Arizona at 33 degrees above the equator we have 10 hours of sunlight and some of my plants are just starting to wake up.

I can't offer any advice or evaluation on the Lithops, they look fine to me. Someone who has experience with them may provide better feedback.

Hi Tim,
It is discussed in here

But to cut the long story short...
Last Saturday, i saw the base of this cactus wrinkled and shrunk in diameter, which in turn, made the substrate looked like as if it formed a "crater" around the base of this cactus. At first, i had thought maybe it had beeb just thirsty and i had watered it. But on Monday, i saw no imptovement...so i un-pot-ed it to check on the root...

I see nothing wrong in the pictures. During winter (shorter days, lower temps) L. williamsii generally get flabby and soft. No amount of watering will change that, in my experience. Mine are all flabby and wrinkled right now. I won't have a chance to take a picture until Wednesday.

Many cactus species do something similar. Not sure if it is day length or temperature or ??? that the plant is reacting to. As the days start to get longer and warmer, it should plump up and return to normal.

Thanks Tim for the input
But, i live in tropic area (Bangkok)...
This December, we still have above 25 degs Cel and no rain at all
And as far as i know, the day lenght is still in tropic area

Doesn't that make the cactus feels as if it was always summer?

Thanks

[Edwindwianto]

Just bought an Ortegocactus macdougallii

As always, i have to clean the root from the black sticky dirt that the seller gave me
I can't understand, why do seller always use this kind of soil...it is sticky and holds it shape...
Not an ideal cactus soil at all

I hope this orange color at the base of the cactus isn't a bad sign

The final result after i re-pot-ed it

I hope i can take care of it, since lifle says that it is quite difficult to take care of

Did you see the Ortegocactus macdougallii+ Opuntia humifusa chimera on the llifle page? Pretty wild!

Yes Shane, this one...hahaha

It is said that nobody could create chimera!
And they are said to be unstable...they could lose their chimera form

But, i'am not a fan of monstrouse or cristate or (maybe) chimera...but i still love color mutation (variegated plant)

It's an interesting cactus chimera. I'm not aware of any other cactus graft chimeras whose tissues are neatly separated into layers like this one. Very cool
