I have a branch thats been in veg for like 2 months and it like as thick as a nickle its still safe to clone right? as long as i do it right. I dont wanna risk taking this big of a branch off then having it die a couple mins later lmao
I mean, a super small branch is obviously going to be more difficult to clone, but given that it has enough leaf to support itself, then yes, it does not matter how much stem is there.
Too big isnt good either- If the plant has too many leaves and can support itself well enough with photosynthesis, it may not root. Sometimes leaves need to be removed or trimmed from a clone so that it doesnt soak up too much light.
