Re: Hana's cacti
Although today is the end of July, a degrafted Strombocactus disciformis was in flower in the afternoon.

Re: Hana's cacti
I think it takes one more month to be able to see flowers but some Turbinicarpus valdezianus have pushed flowering buds up.
The photo is one of them and it was taken in this morning.

An aloe on my frontyard has pushed flowering buds up. Spring is not too far.

Re: Hana's cacti
The photo is a Discocactus species. I bought seeds and sowed in August 2007. The name tag of seeds said "Discocactus placentiformis v latispinus f major HU640". Three plants have survived.
The photo is one of them, 17 cm in diameter. I am not sure but other two are just 10 cm in diameter.
As you can see on the attached photo, the pot has been tight for the cactus. I am not sure what size this cactus can reach but I will use one up larger pot anyway.

Re: Hana's cacti
I lost an old super kabuto in this morning, which is sown on the photo. The cause of death is rotting bottom.
Seed was sown on 24th August 2005 which means the cactus was almost 18 years old.
Super kabuto is a small asterias but the cactus on the photo reached to 16 cm in diameter.
I wished 20 years life at least but the cactus left earlier. The photo was taken last week.

Re: Hana's cacti
Did you determine the cause? Maybe insects, mites, rodents, soil pathogens, or sunburn?Hanazono wrote: ↑Tue Aug 08, 2023 1:01 am I lost an old super kabuto in this morning, which is sown on the photo. The cause of death is rotting bottom.

Re: Hana's cacti
G'morning everyone,
Thanks for your comments.
Please have a look the photo 2 which is upside down of potting soil. Since I cut tap roots off when the cactus was 2 years old, you can see fine roots network only. These all fine roots also rotted.
As shown on the photo posted Tuesday, the pot is quite tight which means the area of water evaporatin from top is very limited.
Cacti can not speak but I can communicate during growing season. They respond to watering and so I can take necessay actions.
Unfortunately it is winter which is not cacti growing season.
I still have kept some siblings of the cactus. I hope they live longer.
Frank
Thanks for your comments.
Yes I do. It is a bit ugly but please have a look the photo 1. The rotting starts from bottom. Top surface is alright but it is too late to rescue.Do you have a rot photo of the plant?
I am not sure the actual cause of the rotting. Since it is winter in here, I stopped watering in May and do not restart yet.Did you determine the cause? Maybe insects, mites, rodents, soil pathogens, or sunburn?

Yes they are, because they started from seeds and I looked after longtime.Thinking the same thing--they're almost family at this point. I'm sorry, Frank.

Re: Hana's cacti
Hi Frank
Something I learned about the shape of pots from a Japanese orchid grower's website. He was trying to grow larger sizes of a particular difficult orchid and found pots with sloping sides are best way to drain water. A pot with straight sides like the one in your picture retains water for much longer. This was also mentioned in Dr. Borg's book on cacti. I have exactly the same problem. It is hard to find pots with the sides more sloping. Bowls are one answer but it is hard to find small ones. I guess it is something to consider when making your mix and watering cacti - (especially older ones) - in pots with straight sides.
This is the Tanaka web site were he talks about the pots...

Re: Hana's cacti
G'morning Mike,
Thanks for your information.
Top and bottom of G-pot has special shapes.
Unfortunately G-pot is not available in Australia and so I imported G-pots from Japan. G-pot is made by recycled plastic and very solid but it is not so expensive. Problem is the delivery cost. The pot supplier can not export pots directly to Australia and I used a handling agent to export. The cost of the agent is around 3 times of the price of pots.
The maximum size of G-pot is 6 inches. I use orchid-pots for lager than this size. The pot supplier is an expert of orchid-pots.
Frank
Thanks for your information.
Actually I use a special pot for old cacti, which is called "G-pot" designed for cacti. I attached a photo of the pot where the rotted super kabuto was in.This is the Tanaka web site were he talks about the pots...

Re: Hana's cacti
Thanks for explaining what a 'G' pot is. Around 8 years ago I was searching for attractive plastic pots to grow Haworthia in, and found a dealer in Japan that could supply an order with various sizes. The shape of the pots is identical to your image. I noticed the mold they formed the pots with had a raised 'G' on the bottom, but I didn't know what it meant. BTW, not only do these black plastic pots work well for growing Haworthia, they look great for potting other leaf succulents as well. I haven't tried them with any cacti yet.Hanazono wrote: ↑Tue Aug 15, 2023 1:21 am G'morning Mike,
