the leaves aren't burnt but there sort of dried up I left them in the sun too long 8(
Is there anything that can be done to resurrect them?
Any info is appreciated
Ayahuasca is the name for a mixture of plant materials stewed together, most of which is not leaves. Do you mean that you are growing a plant used in ayahuasca and that it has died? You may be able to resurrect it by watering it and moving it out of direct sunlight.
It contains caapi? What kind of leaves are you drying? Caapi is the vine--you would just use the woody material for that. Perhaps Psychotria viridis leaves?
A plant with that level of wood could survive dehydration and sunburn. I it looks a bit waterlogged though. I suggest reading about some basic gardening techniques.
leave root/plant to dry on newspaper for about 12 hrs
replant with new soil, fertiliser then water
buy one of them moisture meters off ebay or amazon it will let you know if it needs watering.
