Hi here is your Answer
There are four major factors which influence the nature and growth of vegetation. These are: climate, soils, nature of the surface, and man. Where the factors are favourable, plants grow well, where they are not, plant growth is slowed down.
Climatic factors
These include temperature, rainfall, insolation and winds.
The most critical of these factors are temperature and rainfall and a proper balance must be maintained between the two for plants to grow well. An example, in cold lands,plants growth is impossible below 6°C no matter how heavy the rainfall is. That is why, in the temperate lands, plants grow well only in the summer when temperatures rise beyond this critical level, but shed their leaves and remain dormant in the winter when temperature drop below 6°C. In the cold tundra region, there is no plant life most part of the year.
wind affect vetation too. Persistent strong winds in one direction may permanently disfigure trees and bend them in the direction may permanently disfigure the trees and bend them in the direction of the winds. In the African savannas, strong winds from diverse directions force the plants to adopt and umbrella shape and thus show a thin edge to the wind
Sunlight also affects vegetation. As we know, plants need sunlight to grow well. That is why the leaves and branches always grow towards the source of light. We say that they are positively heliotrophic.
Soil factors
Soil factors, otherwise called edaphic facors, are also relevant. The actual thing about rainfall that matters to plants is not the amount that has fallen, but the quantity that remains in the soil to become available to plant roots. The nature of relief and soils is therefore important to vegetation in this regard.
Factors of landforms
Factors of landforms, known as geomorphic factors, affect plant growth in at least three ways.
First, where every other thing is equal, steep slopes, which have rapid run-off, have less dense vegetation than more time to sleep into the soil

Biotic factors
Biotic factors relate to man and his animals, and they affect vegetation too. Whereas animals graze and destroy vegetation, man can destroy as well as grow plants. He cuts down trees to give way to roads, houses, factories and other cultural features. He burns bushes for farming, and harvests timber from the forests.
