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
