I couldn't find this topic on the forums so figured I'd check with everyone else. My mom was in town this weekend and I was potting up my latest plumeria seedlings, when she mentioned it was time to pinch the tips to encourage branching. Some of my older seedlings started branching on their own so I never considered this.

My mom lives in SW Florida and is who got me hooked on plumeria as we had a massive collection in our yard and we would go out and take cuttings and just stick them in the ground every spring.

Does anyone else pinch off the top of young seedlings? If so when is best or should I let them do their own thing?

I have never heard of doing this, so don't have a clue. I have only been growing seedling for approximately 3 years and like you, I just allow mine to branch on their own. I do know that cutting established plants encourages branching. I just never thought to do it with tiny seedlings. I hope others that are more experienced than I will chime in.

I don't ever pinch my plumeria seedlings. They need to grow tall and strong to become trees....

I never pinched either. I do have one that I accidentally broke the tip off and it's branching. Was unexpected. I may experiment with 3 or 4 as I have about 50 seedlings going.

Experimentation is good.
