Pawpaw jam cooking/ recipe
Determine the ripeness of the pawpaw fruits, process them into fruit puree, cleanse the seeds and how to stratify pawpaw seeds
Asimina triloba: enjoyment ripe
Most varieties are green-ripe, so they cannot be distinguished from unripe fruits by their appearance. Some fruits take on a yellow colourbreak.
They are ripe when they fall from the tree (ensure a soft landing) and ripe for picking when they feel soft - feel the fruit very gently with your handplate(not the fingers) so as not to leave any bruises(picked fruit can be stored up to 1 month in the fridge, perfect temperature would be 1 °C).
A strong odor is also an indicator of ripe fruit.
The ripe fruits are very soft and should therefore not or hardly be stacked.
Cleaning the seeds:
Removing the last remaining pulp / seed skin from the seeds can be very time-consuming. If the seeds are stratified moist in the refrigerator, they have to be completely clean, otherwise the mold will do the job and can get into the seeds after some time. If the seeds are naturally sown directly outside, they do not have to be cleaned! There you can also simply sow rotten fruits (2.5 cm deep).
Option 1 barrel:
A tip from my colleague Andrej Krasna made it very easy for me! A high pressure cleaner is perfect(But also a drill with grinder stirrer goes). I take a sturdy 30 liter barrel, put the seeds with some water to swim in (otherwise the high pressure cleaner could damage the seed coat) and hold the pressure cleaner with the nozzle just above the water surface. When the barrel is almost full, I pour the contents into a vegetable box as a sieve. Repeat the process approx. 5 times until all seeds are completely clean.
Option 2 cage:
I have built a beautiful lattice cage with fine-meshed wire mesh, where the seeds can be cleaned with the high-pressure cleaner at the speed of light. It is even possible to start with whole fruits when they are already overripe.
Overwintering / storing / stratifying the pawpaw seeds:
I store the seeds directly from the harvest in autumn moist and cool, they are then ready to germinate in March.
Option 1 fridge:
The seeds can be stratified in a plastic bag in the refrigerator, the surface should always be moist, I don't seal the bag, I just fold the top so that air can be exchanged easily. Regularly check whether the seeds are moist, if a bit of white mold forms this is not a problem at first, cleaning again with water is sufficient.
The rule in normal small pots:
Example of Airpruned 1 year old pawpaw seedlings grown communally
In the US there are the Treepots and "DeepPots" shown here, narrow and very high.
Unfortunately, I am currently not aware of any German manufacturer or importer.
I know that commercial growers simply use P9 pots(9x9x9cm), until seedlings are 2 years
Who orders seeds can also do a direct sowing at the destination of the tree.
