HELP! Seedlings dying over and over again.

[9fingerleafs]

its only affecting about an inch deep below the coco, i bury the plants deep so they get support with the wind and all but never had this hapen before, just below the roots start and the branch gets though again, only an inch of slugy rotten branch at the exact spot kills the entire plant

Interesting. Do you think maybe you built up the medium too high on the stalk and you got rot somewhat like a wooden fence post in wet soil? Because I use soil I will often stake my plants for support against the winds. When they are young cuplings I will simply use cheap bamboo chopsticks and when I re-pot I go with something a bit more substantial. You're issue is something I've never come across and it intrigues me. Thanks for sharing.

You are very welcome. This is a very hard situation for me but i threw 20 seeds in water and took 25 more clones and I will fill up my pots again soon. But for a less experienced grower this would have been just devastating. This kinda situations happen often and it’s the reason many people don’t grow for long. Sooner or later you encounter a wall that’s hard to climb. I just hope someone with dying plants with apparently no reason can stumble in here and learn something. Thank you for caring and for sharing too. Best of lucks my friend

Have you used the trichoderma before with success or is it something new? I have never used it. However, some species of trichoderma are serious fungal pathogens in shiitake mushroom cultivation. They attack and colonize both the shiitake mycelium and the wood substrate that the shiitake need to grow. I know that bactrex is supposed to help with roots but not sure what it would do to the trunk of the plant. I would also avoid planting deeper than the natural depth where the roots and trunk differentiate. It may be OK early on during the seedling stage but once the trunk becomes woody I would not cover it with any soil, coco, mulch etc.

Yeah I guess I learned the that lesson the hard way, I’ve used trichoderma before to stop root rot very effectively. It forms a spongy mycelium that makes the root mas much stronger and the top soil/coco hard to penetrate even for water. You can see the white fuzz all around and the plant is super happy. I use it to soak oasis cubes so the clones don’t rot. It’s a pathogen for other fungi, it’s a parasitic fungi in some sense. That’s why it used as a fungicide. A bit ironic but that’s how life rolls
