Brown spots problem with Astrophytum cultivars...

[fanecchissimo]

if you want to save the plant, you can go for a surgical removal.

to me it works 80% of the times. but you will have  recurrence in 2-3 years, if the plant is susceptible...

Hi fanecchissimo, thanks. I have already tried that, please see the second photo of this topic. I will check what happened.

usually you don't need so much tissue to be destroyed. jut the one near the spot!

Hi ALL, This evening I have just sprayed ALL my plants with Ganzo. It took me 2 hours+. I hope I will have an improvement.

[fanecchissimo]

did you try to use a great ventilator about 12 hours per day to avoid condensation? maybe it should help.

Hi fanecchissimo, I used nothing. To-day, it was a beautiful sunny day and I found the time and sprayed ALL. To-morrow should be a beautiful day too, cos the clouds in the evening had red markings. I will open the windows in the morning and the water will dry. THANKS...

Removed them from the greenhouse and put them out on the roof.

koh-yo???...OR...COLD???. They were green in the greenhouse.

Hi ALL, Finally, we came to a conclusion about this problem, and we think it's from the cold...These past 2 winters were very cold here in Malta...Especially were I live, here in Dingli...THANKS ALL...

[fanecchissimo]

what about ganzo results?

[marazz53]

Hi fanecchissimo, nothing happened. I think it's the cold and humidity. I will soon upload some photos that made me cry.

[fanecchissimo]

ok, thank you a lot for sharing your experience.

ty for sharing. cold is a big deal for myrtillo.. that's why i don't love it so much.

Hi fanecchissimo, also inside the green house I had problems with it. I'm testing other stocks to see which is the best stock for my place.
I think the place has to be kept in consideration too. I like it as stock, but you can see my results. I threw away 3 boxes in the dust bin due to this problem, and had to start all over again...Sorry I did not show more photos, cos I really was pissed off...
That's life, you have to struggle to succeed, I do not give up very easily...I'll try again...

[fanecchissimo]

never give up!

Hi fanecchissimo, OK...thanks.
