Regardless of whether the seedlings are weak, overly vigorous, or strong, hoeing should be done promptly during the green-up stage; for fields with a tendency toward excessive growth, deeper hoeing can be done as appropriate to suppress spring tillering. When hoeing, be careful to hoe shallowly and finely, and push apart clods as you go; if the soil is first pressed before hoeing, the soil will not be hollow, thus achieving the effect of loose on top and firm below, drawing up moisture and preserving it.
