@Hetty you are sooo right! I had seedlings I forced into dormancy on their first year (as experiments) placed them on the south facing window and it didn't do a thing all winter long I thought they were dead. Then the last few days, leaves started coming out!
@drdawg, I had the same experience even with my well rooted plumerias I forced into dormancy. Some of them are just now starting to shoot baby leaves, others are just now starting to have shiny tips or signs of growth.
@cyra, thanks for the info! Most of the plumeria experts have well controlled climates (like nurseries), which I don't have, which give them better success rates in their experiments. My experiments had to be conducted in a real harsh environment (unfortunately) where Mother Nature can either help it be a successful or make it a failed experiment. For now, am still wounded and still keep apologizing to the mothers of my DSPs experiments
so I will keep my air-layering experiment on hold for now, and maybe I will start with just 1 not 2 branches. I'm eyeing a crooked DSP branch that may be good for it.
by the way, the mother DSPs are doing great and I think will forgive me with new branches from where I cut my failed air-layering.
