Redtop

Redtop should be watered once every 1-2 weeks, depending on the weather and how dry the soil is. When watering, it is important to thoroughly moisten the soil and ensure that the water is reaching the roots of the plant. Make sure not to water the foliage, as this may cause fungal diseases. Always water in the morning so the sun can dry the soil and foliage quickly. When the soil is dry to a depth of 2 to 3 inches, give the plant a deep soaking until water drains from the holes in the bottom of the container or runs off at the soil surface. Once established, reduce watering until soil is almost dry before watering again.

Redtop (Agrostis gigantea) prefers a full sun environment as long as it protects it from intense midday sun. During the spring and summer, redtop should receive at least 8 hours of direct sunlight per day. In the fall and winter, you can reduce this to around 6 hours per day. If you can provide more, your redtop will likely be even more vigorous and lush with growth.

Redtop (Agrostis gigantea) should be pruned in the late fall or early spring. This species should be lightly pruned to maintain an attractive appearance. Pruning should remove no more than 1/3 of the foliage and should focus on removing any dead, damaged, or diseased branches. Deadheading spent flowers will also help keep the plant attractive.
