    It can take a few years after flowering age before it can be old enough to bear a fruit. If you do not fertilize with citrus fertilizer, then you could be just lacking in nutrients.

    Here is an article for general citrus care: https://www.gardeningknowhow.com/edible/fruits/citrus/fertilizing-citrus-trees-best-practices-for-citrus-fertilizing.htm

    I wouldn't know of any classes in your area, but there is much literature on the subject online. Depending on the type of orange, there are many bitter species, and it could have been one of them. Here are a few links to information on the subject: https://www.gardeningknowhow.com/garden-how-to/propagation/grafting/

    This can be pinpointed to a few different things. It can mean the oranges need more time on the tree, or it can mean that the tree is lacking in fertilization. There are a few other likely causes as well. This article will help understand why this is happening and offers solutions to help prevent this:

    I do not believe that we have a photo of this. But the collar is the enlarged portion that develops at the base of each branch. Cut down to this swollen part. It needs to retain the collar to protect against infection. The new sprouts just refers to any new growth.

    Generally the most damaging content in wine is the sugars. The sugars encourage bacterial and fungal growth, which in turn can kill the plant.

    If this is a potted tree you could try lifting the plant and examining the roots. If they are firm and alive, certainly try removing as much soil as possible and replace.

    If this is a tree in the ground and it shows no sign of growth, there is little to do.

    It is normal for flowers to drop off that have not been pollinated or have the tree drop some small fruit.
    Often a gardener will help the tree thin it's crop.
