I want to grow Paw Paw (Asimina triloba) in a Zone 5 area. According to the zone map, I am in 5b. The temperatures sometimes drop below -20, so I'm thinking microclimate with companion plants. I have a large crabapple about 25' from the house, on the southeast side, and a large arbovitae, about 30' away, on the east side. As the paw paw is a part sun shrub, I'm thinking that this would be enough protection from 'snaps' that might go colder. What do you think?
Yes, this should provide suitable protection.
I just got two Paw Paw trees, about two feet tall each. I live in Wisconsin, Zone 4, and want to see if I can get the trees to grow here. Can I plant them in pots and keep them indoors over the winter, then plant them outside this spring in a protected area?
Yes, that should be fine. As long as the trees have suitable protection.
Need info on how to grow and prune paw paw trees.

Grateful if you could advise me on the preparation of the growing medium (soil) for pawpaw. I intend to do it in containers with following dimension 50 cm x 50 cm x 50 cm.
Pawpaws are adaptable and will tolerate many different soils. The best soil for pawpaw, however, is a deep, humus-rich loam with good drainage. They do not tolerate water-logged soils. The soil acidity should be in the range of pH 5 to 7. Depending on the type of soil you have, the addition of organic matter (such as compost) will greatly enhance its fertility, as well as drainage. A good medium for container-grown pawpaws would be a medium to lightweight potting soil mix (generally, well-draining potting soil mixed with compost). Make certain the containers are at least 10 inches tall to accommodate the roots as the pawpaw grows. It produces a long tap root, which will eventually make it more difficult to grow in containers. Therefore, it may be better to put them in the ground. Here is more information: https://www.gardeningknowhow.com/edible/fruits/pawpaw/growing-pawpaw-trees.htm
Mold has developed on my Paw Paw tree leaves. Will this affect the fruit? What do I do about this problem? Thank you.
You tree has a fungus and it is hard to say if it will directly affect the fruit. Some fungus do affect the fruit and some do not. I can safely say that even if the fungus does not attack the fruit, the quality of the fruit will be affected as the tree will expend energy on battling the fungus than growing its fruit. The best way to treat this is with a general fungicide. It is also a good idea to see about increasing airflow in and around the tree as this will help prevent the fungus from developing in the first place.
My paw paw trees are growing well, but the fruit gets spots on them about halfway through their growth and ripening.
Unfortunately the Paw Paw fruit is susceptible to Black Spot disease.
You can spray with Cooper spray prior to the onset of cooler weather.
Keeping your tree healthy will help if fight off this fungus.
Use a well balanced fruit fertilizer in the spring and autumn will ensure that your tree gets the nutrients it needs.
I planted seeds from a red paw paw and have two trees with fruit now growing, but one is a red paw paw fruit tree, and the other yellow. How is this possible that I ended up with two different fruits? There is no possibility I planted any yellow seeds.
The original Paw Paw Tree was likely a hybrid. The new seeds will produce some version of the original.
