Field observation is the key to making appropriate crop cultivation decisions. By observing the fields and the surrounding environment thoroughly and regularly, farmers will keep up to date on what the conditions in the field are like. Hence, we will be less likely to encounter any unexpected problems, such as pests, weeds, or drought and will usually then be able to handle any oncoming problem in time.
For a crop like garlic, weekly observations are usually frequent enough to anticipate any problems. After each observation we determine when we have to do the next observation, based on the conditions found in the field. Field observation is best done during the early morning hours, because later in the day the sun becomes too hot and bright for careful observation and causes most insects to hide in cool, dark places where they are harder to see. Hand recording of data in a notebook is important so as to establish good record keeping.
The mid-spring field observation is an important time in the garlic growth cycle. Planting the garlic cloves was done in October-November. Harvest occurs in July. The mid-spring field check is used to evaluate the over-all crop health, uncover any pest or disease problems, and determine weed pressures.

In order to draw conclusions about the condition of the crop and actions to be taken, we do not have to observe the entire field; observation of a representative sample is sufficient.
