Male and female flower parts are present AT THE SAME TIME on any given pawpaw tree in bloom. Each flower starts off in the female stage and then proceeds to the male ‘pollen shed’ stage about 3-5 days later. ANY pawpaw tree that has been blooming for more than 4-5 days will have BOTH stages of bloom happening simultaneously. Just to clear that up.
…well, I’m going to try giving my friend on Long Island (7B) a couple of scions with multiple fruit buds (in March) from a few of my trees (6A) and let him try to force them into very early bloom to coincide with the bloom on his fruitless mature trees…(from root suckers from the same tree)…he can stagger the scions a few days apart to hopefully create a pollinating window…..so perhaps an actual data point……how about that….. stay tuned….Beemster
real good! springy right now, it’s been freezing so it’s dormant. it put on a few inches last summer, it’s been slow growing but it’s in shade so i expect it to be slow. just gave it its “spring feed” this past week, should give it a boost when the season changes.
@Blake and any others who attended the recent KSU Pawpaw Conference: I’ve watched almost all the videos and see no mention of the annonacin/acetogenin content of any KSU cultivar, even though at least two speakers covered this topic. It appears this info is still a closely guarded secret and leads me to infer that the levels must be high in KSU cultivars. Or maybe I just haven’t seen the right video.
Blake, and anyone else for that matter. I live about 30 miles north of Houston, TX, and have over 100 Asimina triloba seedlings in 4” x 12” plastic “liners” outside (less than 1 year old ranging from 4” to about 14” in height). In the madness to protect my 100s of in-ground citrus trees and other semitropical plants from our brutal freeze (we have been below freezing for about 36 hours now), I left these pawpaw seedlings sitting outside. I checked them this morning and the ProMix in them (and even some in 1 gallon pots) are frozen solid. Do you think they are toast now? I am heartsick thinking about it. Is there any hope for them?
I’ve had roots completely freeze in pots and they’ve always woke up okay. There’s probably a threshold where the roots may be too cold for too long, but I wouldn’t stress too much over it. I’m sure there’s people in the Midwest that have had some nasty frigid airmasses with little or no snowpack that has allowed the ground to freeze pretty far down.
If you can thaw them out and remoisten them I think they would be okay.
