Name the two factors that are important for the spread and dense growth of trees.

“Soil compaction is the most prevalent of all soil constraints on shade and street tree growth…Many people become obsessed by small constraints on trees while major life-altering impacts are ignored. Soil compaction is one of those major problems causing significant tree stress and strain, and whose impacts are usually blamed on other things. Figure 1 shows the individual items causing the greatest growth limitations for tree growth. The top three things (by far!) are soil water availability, soil aeration, and soil drainage — all three greatly disrupted by site compaction. Drought and soil compaction head the list of major tree growth stress problems” (Coder 2007) [bold added]
Answer:
Photoperiod (Sunlight): The duration of sunlight is called photoperiod. Photoperiod depends on latitude, altitude, season and duration of the day. Trees grow faster in summer because of longer photoperiod. Precipitation: If an area gets heavy rainfall, it is suitable for the growth of dense vegetation.
