Just simple 2x2 framing and covered with solar blanket material (used to cover swimming pools and this stuff really keeps cold out and heat in. Since mine is inside the garage, I am not using treated lumber. If outside, I would certainly used treated lumber and the base would be 2x4' rather than 2x2". Practically anyone can build one.

Lucky, come to the Greenhouse forum!

do you use any lighting or heat lamps or ventilation for the green house in your garage?

You get lots of greenhouse ideas here

Lucky, lets go to the "Greenhouse" forum and continue this discussion there.

Cuttings - with no roots - should not be in the same mix as your plants; they should ideally be in a few inches of pure perlite or 30/70 soil-perlite mix. And they should not get watered until they are showing leaves. I realize you are in a very dry climate so you could mist them and the rocks in a saucer underneath it are fine, as long as the cuttings do not sit in wet soil.
Once they are showing leaf growth you may assume they are rooted and can pot them up in the same mix as your plants.

I am very averse to using any kind of bloom booster (it is designed for annuals, not flowering trees) but I know many people use it.

It would be fine to repot the plants at this stage, and when you do you may remove (as in cut off) some of the larger leaves to prevent dehydration. They will soon put new leaves on if they are happy.

What's the chances of the cuttings surviving?

As long as they are still hard and not showing signs of rot they should be fine.

Good luck!

What are some signs of root rot without pulling the cutting up?
My Cuttings I brought back from Hawaii are doing just fine sprouting leaves.
The ones I bought from Amazon that were 2 weeks behind the one I brought home still have not produce leaves yet?
Any advice?

I think you are looking for 'failure to thrive' but personally I would pull them up. If they have roots they will make new ones, and if they don't you haven't lost anything.

thank you :)

DrDawg- I couldn't find any Black Kow. Would a mixture of Cactus Palm Citrus Soil work?

I don't know Lucky. I get my Black Kow at Lowe's, and every Lowe's and Home Depot in the area carries this product. I have never used that citrus soil mix. Other's, particularly those in Florida who grow citrus, will probably be able to tell you what is in it.

Thank you. Do you use the Black Kow for fertilzer with the plumerias or to help with drainage. I did some research and it says its "Composted Cow Manure"
I just now realized your website in your signature :-)
I read your introduction and would like to say "Well Done" and "Very Nice"

Lucky. Tropical Plants & More keeps me busy in my retirement.

No, Black Kow is added just for its compost-basis. It also provides very low-dose fertilizer and it will never "burn" your plant's roots. It actually would be pretty much the opposite of something well-draining, though I have a feeling that it has sand in it so it does drain. Perlite opens up the potting media for that (draining). Oddly enough, just this very moment, I returned from Lowe's and brought home three bags of the Black Kow and three bags of the milled sphagnum. That's 12 cf. and it won't last the month. Those two items make up 2/3's of my general purpose potting media. I will mix a bag of each, plus perlite, plus Osmacote in a large wheelbarrow and use that mixture when re-potting. If I want to open up the mix even more, I'll add a good measure of chopped cypress mulch. That super-open mix would be used for my terrestrial orchids.

Wow, that a lot of soil! Maybe home depot has it way in the back out side. I've already repotted the ones I bought from home depot but I'll still have to check on the Black Kow when it's time to repot my cuttings. The ones that had burnt leaves are doing well in the shade now. Well... the leaves are not drooping anymore at least. Still deciding if I want to cut off the burnt leaves though. If I do that, I'll be left with about 3-4 leaves on each Plumeria. If I cut them off will the plant go into shock?
On another note I saw a few strings of a spider web on two of them. Nothing fancy like a whole web but just 1 strand from one leaf node to the top leaf node.
But we do have a lot of spiders in our area. I killed a Black Widow 2 days ago in my garage who had a nice web built under my work bench.

Keep removing those webs. I remove yellowing leaves constantly and often will cut off damaged leaves, removing the brown part. It does not harm the plumeria to do so. In fact, when rooting a cutting, you want to cut those larger leaves off, leaving only the tiny, terminal leaves. That directs energy into rooting rather than into those large leaves.

Black Kow is out in the garden centers here, outside with all the other large bags of potting/garden media.

I go ahead then and remove the sun burned leaves. I've heard of so many places that you should cut them off at but where do you recommend?
The cuttings came with no leaves, just those tiny, terminal leaves you mentioned

Cuttings should have the leaves removed prior to rooting. The new leaves emerging is a sign of root formation.
Just cut the leaves off with clippers about an inch away from the stem; they nubs will fall off by themselves in a few days.

Lucky, I simply cut the leaf where there is healthy tissue. Depending on damage, that/those leaves may fall off regardless. My trimming is done more for esthetic purposes than for anything else. I like neat-looking plants. Your cuttings sound fine as they are.
