    Brown spot on stem of Phrag Kovachii

    I've been looking for a long time now but I don't see any brown spots...🤔 The roots can't be that great because I can see a "drying out" on the leaves on the trunk. Other than that I don't notice anything else.

    Paphiopedilum stonei

    ...and I just thought: "he can't do sanderianum but stonei, congratu... oh". Should always read the small print first. 😁 Just kidding. Looks awesome! Thx. I have two small young plants which will take some time.

    Brown Spots on Paph. Roth leaves! Please help!

    It also looks like it could be the same fungus than this: https://www.slippertalk.com/threads/round-fungus-spots-attacking-my-paphs-if-some-of-you-have-insights-on-a-durable-solution.56807/

    Brown Spots on Paph. Roth leaves! Please help!

    I have already experienced that pathogens can enter the plant through the roots. In this case I strongly assume that the substrate is contaminated with something because it occurred directly after repotting. You urgently need other rescue measures for the already damaged and infected tissue but...

    Help for Paph. sangii

    Thank you. I have now prepared new rockwool and soaked it in 10-52-10, adjusted the pH to 5.7 - I have read that it likes it more acidic? I also added Previcur (fungicide) to the soaking water. Apart from that, there are slightly brownish spots on the leaves, some of which look damp (Erwinia?)...

    Help for Paph. sangii

    Hello, this Paph. sangii has been brought to me by a friend. It has hardly any roots left, just enough to survive. It is producing two new shoots. It is currently in rockwool and shaded (2000 Lux) at 75%-80% rH with 23°C / 73°F. Watering every two days with Peters 10-52-10 (0.5g/L -> 410 µS...

    Watering or soaking - whats best?

    "Only" 150 adult plants... 🙈 Lifting 150 times a plant pot over the sinkand letting the water run through is not a small amount of work, esp. for each pot 1 minute is 150 minutes. 😁 I also think that soaking is more time-saving if you can't go over an entire palette with a large shower head...

    Round fungus spots attacking my Paphs. If some of you have insights on a durable solution.

    Instinctively it looks to me as if it comes from the water. The spots look dry!? Droplets stand on the leaves. Perhaps the water is not 'clean' enough? You could try disinfecting the water first. It might also help to water the plants for a while directly on the substrate and not from above. If...

    Watering or soaking - whats best?

    Lately I have watered with a measuring cup over the sink. I have to pour liters of water through it. The water consumption is enormous. The substrate then starts to dry out at the top, very small pots dry out after 3 days. In the past I used to spray directly onto the substrate with a spray gun...

    Watering or soaking - whats best?

    Hi, I was wondering what your experience is with watering methods for Paphs: Watering the pot vigorously or placing the pot in a suitable sized container and filling it with fertilizer water for 20 min? Any practical experience of the differences for the plants growth? Does it not matter? Is...

    General pollination questions

    That's an interesting thought because I was expecting the exact opposite if they are so different.

    General pollination questions

    Hello, 👋 I have a general question about pollination: 🐝 For example if I put the pollen of another Paphiopedilum onto a Paph. lowii, e.g. say (for an extreme example) from a Paph. canhii, would the result be fundamentally different than if I put the pollen of Paph. lowii onto a Paph. canhii...

    Don't let them fly away... 🦅 Nice compact habitus btw.

    New Zealand Tree Fern Fiber

    I'm not dodidoki but I can say when I'm using Peters 10-52-10 (with RO water) the pH is right out of the box adjusted to 5.8. I suspect its the same with 20-20-20 what dodidoki use. I have ordered it also but have not yet been able to test it. In contrast when I use the fertilizer from Schwerter...

    New Zealand Tree Fern Fiber

    Thank you for the advice. You use a systemic fungicide for prevention? 🤔 Once again I have the misfortune that this is only available here in Germany in liter bottles from 80 € and is only sold to people with a 'certificate of competence'. :rolleyes: Few years ago you planted some plants in...

    Do you pre-treat the rockwool? I read that it has out-of-the-box a fairly high pH value (8.0) and should therefore be pretreated. How do you go about this?

    Orchids 2024

    Don't the lowii's up there grow sideways to the window or are they just temporarily stored? That wouldn't work for me... I wouldn't give any of them away. 😁
