I have a couple of comments. I think you are starting them in too big pots. A seedling doesn't need that much room and it is harder to keep the right moisture. I have never liked peat pots and won't under any circumstances use them. They suck the moisture from the soil and they can grow mold on the pots. Do not plant them out in the pot. I know they say they are biodegradable and the roots grow through them but they don't tend to. Years ago when I did try them I dig up a tomato that was in one and the root ball was still in the pot and had not gone through it. I use disposable drinking glasses--not the clear ones. Styrofoam ones are small for smaller plants. 16Oz. plastic ones are for larger plants like tomatoes. I buy my Styrofoam ones at the dollar store--25 for $1--the plastic ones at Walmart--50 for $3. You can throw them away or do like I do and wash them in a bleach solution for the next year. I start my seeds in a shallow communal pot. I like the plastic mushroom containers they measure 5"x4" by 2" high. Then I transplant them into the glasses when they are getting their 3rd set of leaves. I sink the Tomatoes into the soil up to their leaves and they grow roots all along the stem(only Tomatoes). A good way to test if a plant needs water is to stick your finger into the soil. If it feels wet an inch or so down it doesn't need water. Also a pot will feel light when dry and heavier when wet. Your light set up seems to be fine. but your plants seem to be leggy and that is caused by lack of light. It is likely because they didn't get enough light at the start. I hope this helps. Gardening is great fun but it is also a learning experience. I have been at it for many years and every year I learn something new.

Those are probably just the cotyledons. I'm assuming plumerias have them just like other plants. I just planted mine 2 days ago, and I'm waiting patiently until they sprout! How long did it take yours to sprout?

The blooms were very similar to a regular plumeria. The petals were a bit thinner and a little longer. These were from a white flowered tree. I don't know if stenophylla comes in any other colors or not. It wasn't that this was such a wonderful plumie. It's just that I was in the Cayman's and the pods were there. I collected a huge variety of seeds there. Like other tropical areas, many of their weeds are our nursery plants.

Over the past few weeks, it's been scorching in the front of the house where I had my big pot... And since I had the big pot there, the newer ones I bought were placed around in the front of the house as well. Unfortunately, the morning sun has been more extreme than I think they can stand at this time. the afternoon sun will work better. (and of course this morning it was pleasant out in the front this morning...) Lynn, I'm crossing my fingers for your Siam Ruby pod... I wonder what makes the pods rot like you said the others did.... It must be frustrating to wait all those months for them to pop open, then find them rotted out... Hopefully that one will be okay. If it makes it, maybe I can talk you out of a couple of the seeds... lol Anyway... have a great day everyone. ~Bob
