Plumeria cutting not rooting
I got this cutting at the end of August. I never had plumeria before neither seen one ( only on pics). Cutting was not rooted when I got it the man dipped it into fertilizer and said to just stick it into the potting soil ( I got it with cutting from him). I've read the instructions also read on Internet tones of topics. I watered it really well and then ( information differs everywhere one say you should water it as well as instruction, others say don't) I've watered it slightly 3-4 times during these 2 month. But it's just sitting there without slightest change.
Also as I didn't know how cutting should look like I didn't pay any attention to some wrinkles mine has ( I thought when I water it it'll go away) it didn't. It didn't get better or worse. Where it's branching off there are no wrinkles.
No sight of leaves too.
I had it on a sunny south window. But I don't have anything for heating it from the bottom. Now it's quite cool at the window so I've moved it to a warmer place.
Is it ok that it sits so long? I've read it supposed to root within 1-2month.
