Re: When do you introduce fresh air to your seedlings?

1 year sounds like tiny slow growers . I quit growing in sealed plastic so IDK ? Back when I did I think it was months not years. As far as treating them as adult plants, more sunlight, less water, transplanting, its a couple years or up to many years for Ariocarpus. Hi keith, can you share your te...

Yes! Finally found out that this is caused by mites. Tried (experimenting) applying neem oil on one plot and dishwashing liquid+cooking oil mixture in one plot.

Thank you!

Re: Sick Pereskiopsis

Thank you for the insights! Yes, had several recommendations also from growers here to just dispose of the plant. Will do full diagnoses first before doing that (ultimate solution). Had the plants isolated already to prevent contagion (just in case the problem is viral).

The deficiency of these will show up mainly with the new plant growth. Thank you for your insights Harald. I have also thought of your second possible cause y...

Re: Sick Pereskiopsis

My instinct would be that it is an insect attack of some sort but I have no idea which insect pests you have there. I would remove the affected part and a good portion of stem below it and immediately plunge it in boiling water and leave it there until you are sure it is dead. Then wash hands thoro...

Hello from the edge of Western Pacific - the Philippines

Hello from the tropical country of the Philippines. Joined last October 2020, forgot about my registration, and found my way back again while researching a topic on Pereskiopsis disease. Starting to read posts here now but hopefully will see you guys in the other sections. Thank you!

Sick Pereskiopsis

Anyone who has experienced the same? What could be the issue and what could be done to address the problem?

Thank you!
