It can tolerate slightly acidic or alkaline soils, but excessively acidic or alkaline soils may affect its growth. Therefore, it is best to maintain the soil pH within the recommended range for optimal growth of the plant.
Cultivation Methods
Agrostis dissitiflora C.E.Hubb. is a type of fine fescue grass that can be grown in a variety of soils, including sandy or loamy soils. It is best to plant in the spring or early fall when soil temperatures are still warm. The seeds can be sown on the soil surface and covered lightly with soil or hay. This grass prefers full sun or partial shade, and it is essential to keep the area weed-free. It is also crucial to have proper drainage in the area of planting.
Watering Needs

Pruning
Agrostis dissitiflora C.E.Hubb. is not typically pruned, but it is best to mow it often to keep it at the desired height. It can tolerate a range of mowing heights and generally should be mowed when the grass reaches about three to four inches in height. Cutting the grass too short can stress the plant and lead to browning or even death. It is best to use a sharp mower blade and mow when the grass is dry to prevent damage to the grass blades.
Propagation of Agrostis dissitiflora C.E.Hubb.
Agrostis dissitiflora C.E.Hubb. can be propagated vegetatively or by seeds.
Vegetative Propagation
The best method of vegetative propagation for Agrostis dissitiflora C.E.Hubb is through its stolons. Stolons are horizontal stems that grow above the ground and produce roots and new plants from the nodes. When the stolons have rooted or have plants growing from them, they can be cut and planted in soil. This method is effective and results in identical offspring.
Propagation by Seeds
Agrostis dissitiflora C.E.Hubb seeds are small and can be collected from the plant during late summer and early fall when the inflorescences mature. The seeds should be sown into pots or a prepared bed in early spring and covered with soil. They must be kept moist and in a warm environment to germinate, which usually takes up to 3 weeks. The young seedlings should be transplanted once they have grown strong enough to withstand transplanting, which may take several months.
