Tropicals & Tender Perennials: Advice wanted on rooting cuttings, 0 by TomH3787

I ordered some plumeria cuttings from Maui Plumeria Gardens and they arrived today. Very fast service and they even sent a free "mystery" cutting. Pictured (from top to bottom) are Celedine, India, Grove Farm, and the "mystery" cutting. Even though I only ordered single-tip cuttings, the Celedine has three tips and Grove Farm and the mystery have two. I saw the thread Clare posted on plumeria borer beetles so I checked my cuttings carefully. They seem very healthy and firm with no signs of holes or soft spots. I'll keep a close eye on them though.

I read the instructions that came with the cuttings and the "pea gravel method" at plumeria101.com. I like the idea of putting pea gravel at the top of the pots to stabilize the cuttings – I bet that would work with brugmansia too. I am planning on rooting these in 1-gallon pots on the front porch where they will be protected from rainstorms and excess sun while rooting. Our mid-summer temps here are usually 65-70 at night and 85-90 in the day.

Here are my questions:

The instructions from the vendor said to use half perlite/potting mix but plumeria101 says 2/3 perlite and 1/3 potting mix. Which ratio works better? Does potting mix or peat work better?

How easy are these varieties to root? Are any particularly slow or fast?

Any other advice?
