Tree... O Tree... Which one do U wanna be?

Lets assume there is a well grown tree in a tree-farm. The tree has some genes that has enabled it to grown really fast and strong compared to the rest. The tree is contributing to the growth of the others by providing shade - prevent heavy sun on the young ones and also preventing the others from being washed away in the rains by staying rooted firmly to the ground and breaking the flow of water. So this is a protective environment. The tree is an inherently strong one but is contributing to the growth of the farm by sharing using its strengths to let the other grow up well.

Say, the farmer doesn't care for this tree, maybe because he didnt plant it and the tree is growing out of place. So he wants to quash the tree. He doesn't water the tree and doesn't give it manure and doesnt give it a chance to grow and become big, which is what the tree wants to be. He instead gives rich manure and water supply to the other surrounding trees What happens to our tree now? How does it evolve?

1) The tree doesnt have nutrient supply and grows weak and dies.
2) The tree tries its best to survive. It grows its roots deep into the ground to get nutrients from within. But it is just surviving and is no more making a difference to the farm.
3) The tree doesnt give a damn about the other growing plants. It is a survival of the fittest here. There are minerals, and the tree just needs to figure out how to get at these minerals. It is the strongest at this moment, so it will not have any problem in directing its roots appropriately and getting at the goods. It grows and it grows bigger, stronger and better.

Now in any of the 3 cases, the other plants are being artifically nurtured and they will not have it in them to fight the odds like insects and weather. They have not yet developed the immunity to fight disease and insects. Their roots have not grown strong and deep enough to let them hold their own against the storm. They will eventually break down and die unless they are being constantly supported by the farmer in all walks of their life.

So in any case the artifically grown trees will have to live on life-support all their lives.
The originally stronger from within tree just needs to realise that it is the survival of the fittest and grow stonger and larger such that not even the damn farmer is able to do anything about this tree anymore. The tree should grow such that the other trees will want to grown under this tree and have a better chance of surviving the odds rather than growing elsewhere.

Tree... O Tree... The others better watch out, its time to break free!!!.
