Any early germinators
not used could be planted, but once an initial planting came into bearing, it would soon supply all future planting material on a year-round basis and no further introductions were needed until commercial demand for planting material occurred at the start of the 20th century.
Regardless of the particular spring, he explains that delaying treatment tends to mean better spraying conditions and maximum emergence of later germinators
, giving more reliable and complete control.
