The top part of the cuttingThe top part of the cutting

heared off section of the remaining branch

Hi I copied and pasted your question series below and answers to the best of my knowledge:

1. It's a fairly large cutting, and the inner stem is quite woody. Would it root?

-It will likely root as thicker and older branches root better, but give it a bit longer

2. The top part of it branches into 4 individual branches which have been chopped off to keep it manageable. Should I seal (the open wounds) off using candlewax or turmeric (I've heard it's a natural fungicide) or should I let it open and let it callous on it own?

-I would just leave it alone, leave it open to air

3. The temperature here (India) is very hot and dry, it might start getting a bit humid from now onwards (pressumption based on June being the onset of monsoon here). So, should I cover the top ends of the cutting using a plastic bag (then tied to the trunk) to retain the moisture?

-Leave it open, wrapping it may keep too much moisture and cause rot

4. How often should I water it, since it's a fairly large container and the cutting has been sitting a few inches above the base of the pot?

-Fast draining as you stated, your soil should be fine for a full soak... I would only wet the potting media once, then not water until I see leaves.

5. I have one more cutting that has sheared off from a mature tree and is roughly as thick as the one in the picture. This cutting has been broken off, so about 3/4th of it is exposed bark and exposed sheared wood. Should I cut this exposed wood off and then pot it (clean cut part in the ground) or should I let it be?

-Not sure how this one will turn out. I would just cut below the sheared section and try to root the stubby remaining piece, the exposed wood will end up rotting or dying anyway.

Hope this helps and good luck..

Hey, thanks a lot for the reply. This calms my anxiousness a bit, because I'm a newbie to the whole gardening hobby.

As per the advice of one doctor/hobby gardener youtuber to put candlewax on the 4ft tree stub's open ends. His logic was, it's anyway gonna be difficult for the water to reach so far up the stem and the open wounds would let the moisture out. I have not seen a single video of a large Plumeria cutting being rooted, so neither of us knew what was to be done. There are several regarding rooting a thick Bougainville cutting but the requirements of this tree vs a Bougainville are very different.

There are several other smaller thick cutting that have similar open cuts, they have been left exposed.

I've also started to mist water at the green tips of the cuttings using a sprayer. Is that a bad practice?

For the potting media, I have not opted for any premixed soil because it would've become a very expensive affair. I've used a mix of 70% construction grade fine sand and 30% garden soil (slightly clay like). Somehow this mixture still hasn't gone completely dry. Is that a bad sign?

Would it require fertilizers? I have some vermicompost at hand.

I recently discovered that one of my previous batch Plumeria cutting rotted and I'm worried that these new ones will too. I purchased some contact fungicide to that end and was wondering if this would help the current batch.

Also if you know how long these thick cutting would take to show any kind of green protrusion or leaves, that would be quite

No fertilizers for rooting plants. based on the description of you rooting media i think it is too wet. see if tou can locate coarse sand or a pine bark mulch
