Thank you anttisepp! Very interesting.

Probably there is "a" right time to do that. Probably it must be done some weeks before flower bus appear isn't it?

Definitely too late for the plant in the picture below:

What can we do to assure flower synchronization between two different individuals of the same species? I have several "couples" grown in the same condition (even in the same pot). One plant is flowering profusely while the other does not show any flower bud. Besides fertilization (tips are...

I the first picture, right. Could it be M. magnimamma?

ok. Looks very similar to penicillata nivosa with white spines. Yes, anttisep, I saw what did you saw .... your suggestion made me notice that the spines in the first two pictures are whiter. Maybe there is some variation among the plants or some hybridization? But the flowers are all the same yell...

Flowers of pic 1- 2 are yellow, not red

Picture 3 is the same plant of pic 1 -2, unless I have different plants and have not noticed

Thank you anttisepp! But...which is which?

My guesses were:
Plant 1: P. chrysacanthion
Plant 2: P. microsperma aureispina

Anyone could help me identifying these two similar but different Parodias? I have my guesses but as there are several similar species I wouldn't like to influence your's. Thanks a lot! Plant number 1 has totally yellow flowers and straight, needle-like spines: IMG-20230406-WA0093-01_copy_749x800.jpg...

Now I want to show what I have found when transplanting some seedlings. They looked very stressed and the substrate looked very bad.. So I noticed theses injuries at the base of the seedlings. What can it be? Fungus gnaths that gave up or died due to insecticide? The mix has no grit, sand or gravel ...

I don't treat my fungus gnats... this is a bad idea if you have very few seedlings of a specific species but over 30+ seedlings most will survive without issue. I only have them when I start my seeds since the top layer is topsoil but once repotted into 100% mineral mix they just disappear. From wh...

Eryosice senilis?

I begun serioulsy in 2016, when I joined the forum with a few plants in my collection. Today my notebook (how do you call the old thing made of paper? notebook...?)...well...In my notebook every new species (or a new plant of the same species, but from different source) receives a number...currently...

I sometimes get fungus gnats in my seedling propagation box over the winter when it's humid. Since I water the seedlings more frequently they don't have the chance to really dry out and kill the bugs, so I treat with imidacloprid. It's used as a sytemic but I believe it can work as a contact pestic...

Regarding Fungus gnats: I read the label on using Mosquito Dunks or Mosquito Bits for Fungus Gnats. Then I went onto the manufacturer's website and see their product will work for them. I tried it and it really did kill them. I didn't have the bits, just the dunks, so I broke one of the dunks up in...

Hi mmcavall, I also used to have terrible problems with fungus gnats but now just a few . I use diatomaceaous earth powder in my soil mix, have been for 20 years I think it keeps them away. Could also be that I moved away from a area that had swarms of fungus gnats from neighbors raised planters . ...
