I was about to cut off the thorny part of my Japanese mandarin tree when I noticed small fruit growing out. I have attached the photos of the tree with the small fruit, which has a texture like that of a peach. Do I have to cut it and start over? The lower part of the tree is ok, with no thorns. I'm quite confused. Please help
How old is this tree?
The thorns are not necessarily a red flag. Many young citrus trees develop thorns to protect their delicate vegetation. As the tree matures, it should grow thorns less frequently. This article will explain the thorns in more detail:

Is this the first time this tree has started fruiting? If no, has it ever fruited successfully? If yes, then it may be too early to judge on the fruit. If the fruit, after full development and ripening, turns out abnormally then you may want to consider that the rootstock may have overtaken the scion. Almost all citrus trees sold are grafted trees. The desired tree is grafted onto a very hardy but inferior fruit tree. This insures the superior fruit have a strong root system. But, sometimes, mostly due to damage to the scion (the good tree), the rootstock takes over. Once the rootstock takes over, the only thing to do is to remove the tree and start over.

Just wanted to ask you about my mandarin tree. It doesn't seem to be growing at all. It has yellow leaves and doesn't look healthy. I fed it a couple of times with cow manure. Should I be doing this regularly? Also, I've been using grass clippings around it. If you can help, will be great. Thank you.

Honey Murcott mandarin- the fruit is smallish and some are greenish in centre and hard when cut open. What does my tree need? Have an orange tree one side and a lemon the other and these are fruiting perfectly. The trees all look green, lush and healthy. 3 years ago had the best fruit on the mandarin, so huge and juicy. Now it's been diminshing every season. Help please.
I would recommend a soil test. You could have an imbalance in Nitrogen/Phosphorous levels.
Check watering, even though 2 of the trees are doing well, water is key to citrus success.

My Gold Nugget has thorns on 80% of the branches. I planted it three years ago. I have read that these trees don't have thorns. They are not suckers. The branches start at about 10 inches above the ground. Do I have to prune them? I know that it is a Gold Nugget because the first year put out some fruit. It was very sweet but hasn't flowered again and I don't know why.

This is just a follow up question regarding my mandarin tree. I have started to prune the thorny trees and realise they have started growing fruits I don't recognise. I have attached the pictures. Should I continue cutting the trees off?
Only prune dead or damaged branches in the spring.

My dad has a mandarin orange tree and the fruit is sour tasting. How can we get them to produce sweet fruit instead of sour fruit?
There are many factors that go into growing good citrus fruit, including temperature, watering, fertilizing, pruning, correct harvesting and the variety that you are growing.
Optimizing the growth of the tree will help in the final product, but keep in might that some varieties are actually a sour fruit. These citrus are used for jelly and jams.
Another issue is root stock take over. Root stock of citrus is generally a less flavorful citrus variety.
