the 3 year old TLD I was gifted from Jandey's famed TLD rooted from a two tip cutting grew rapidly blooming the first year, taking the second year off, and then bloomed all last summer. The runs between branches is about 1/2 to 2/3 of what yours looks.

I think if you were to up pot it to as big of a container as you can and as much sunlight as you can offer you stand a good chance of it filling out. If you could only do one I would suggest more direct sunlight.

Based on that size I would have it in a 10 gallon container. Understood that 10 gallons may be too heavy for some to move inside and then back out but the more room for roots means more nutrient uptake and more ability to take strong sunlight. All of which translates to more blooms and more tips. Good luck and hope this helps.

can you post the pic of your TLD?

I'm not sure where it specifically is in the greenhouse...or um which greenhouse its currently in (sounds worse than it really is). I might be able to post something in a week or two as I start to unravel the "Plumeria Tetris".

Ahhh, reverse plumeria tetris...so much more fun than the winter plumeria Tetris! I'm getting spring fever! When I find mine I'll try to post a pic too.
