Love the way you do Air layering (tarp ging) by using Kapi. I live in US. I'm not sure I can use Shrimp paste to do the same. We have Rooting hormone to do it. Thanks so much I enjoy watching you. I plan to do tarp ging on Apple tree in May it's still too cold to do anything. Good luck. you can write in Thai. I never learn how to type in Thai. Why are you not put Kapi on the node(tar ging) directly?
