Final answer:
The ideal number of fertilizer applications for grasses depends on various factors like grass type, soil condition, climate, and desired growth rate. Option 1 (2-3 applications per year) and Option 2 (4-5 applications per year) are both viable choices, but adjustments should be made based on specific needs. There are grasses that can thrive with only 1 application per year, while others may not need additional fertilizer if the soil is already nutrient-rich.
Step-by-step explanation:
The subject of this question is Biology.
When it comes to fertilizing grasses, the number of applications needed depends on various factors such as grass type, soil condition, climate, and desired growth rate. For most grasses, the ideal number of fertilizer applications per year falls within the range of 2-5, so Option 1 (2-3 applications per year) and Option 2 (4-5 applications per year) are both viable choices. However, it is important to adjust the amount and frequency of fertilizer based on the specific needs of the grass and the conditions it grows in.
For example, a cool-season grass like Kentucky bluegrass may require 2-3 applications per year, whereas a warm-season grass like Bermuda grass may benefit from 4-5 applications per year. There are also grasses that can thrive with only 1 application per year, such as certain native grass species that are adapted to low-nutrient environments. On the other hand, if the soil is already nutrient-rich and the grass is growing well, there may be no need for additional fertilizer applications (Option 4).
