The main productive life of a lemon tree is approximately ten to fifteen years. The tree can live for forty or more years and continue fruiting although sometimes not as prolifically.
orangutans (correct spelling?) eat different fruiting plants that grow in the forest (rely on fruit) and one of there preferred fruits are from a tree called the durian tree.
Prune it during the growing season. but dont cut off any fruiting wood unless you have to.
Pruning a medlar is not essential as it is with other fruiting trees. You can thin branches to let more light into the center of the tree and remove dead wood, but that is generally all that is needed.
Yes, remembering that most of the fungus is not the fruiting body that you see on the surface but the michorizo that exist hidden in the tree or the soil.
Fruiting Bodies
Heat can induce fruiting in mango's as well as moist air.
Ring barking is a highly skilled job for someone who knows their craft. A tree can be ring barked to control growth and encourage fruiting but, a complete circle of ring barking will kill any tree that it is done to..
Potassium is way more important for fruiting plants.
Fungi generally reproduce using fruiting bodies.
