Under adequate moisture conditions, internodes will be longer, resulting in more widely scattered new shoots. One plant can spread to occupy and area 2 m 2 in 2 years. Tillering is induced by photoperiod and temperature and modified by soil moisture, nutrients, and defoliation. Production of tillers of Kentucky bluegrass is enhanced by relatively cool temperatures and short photoperiods. Thus, most tillering takes place in the spring and fall.
Some tillers produce inflorescences, while others remain vegetative.
Vegetative tillers eventually form true roots, allowing them to be independent of the parent plant. Each panicle of Kentucky bluegrass produces between 100 and 200 seeds. Few studies report on the seed bank characteristics. Kentucky bluegrass is primarily used as a lawn grass and as a forage species. It can not only tolerate successive, intensive defoliation, but it may flourish under these conditions.
