fountain grass

Fountain grass prefers regular watering, with an average of 1 inch of water per week. Keep the soil moist at all times, but avoid over-watering. The grass should be watered deep and infrequently, allowing the top 6 inches of soil to dry out slightly between waterings. During the hot summer months, water the grass every 3-4 days, and during the cooler winter months, reduce watering to 1-2 times a week. Always check the soil moisture before watering.

Fountain grass (Pennisetum setaceum 'Rubrum') thrives in full sun for at least 6-8 hours a day. When grown in the shade, it tends to be leggy and less vibrant in color. It can survive in partly shady conditions, however, this could reduce flower size and vigor of the plant. For optimal growth, provide fountain grass with at least 8 hours of direct sun per day; more sunlight is beneficial.

Fountain grass (Pennisetum setaceum 'Rubrum') should be pruned once a year in late winter or early spring while it is still dormant. Aim to prune no more than ⅓ of the plant's foliage back to the base, removing only a few of the oldest stems to allow new growth to come through. Be sure to use scissors or shears to cut the grass at the base, instead of pulling it out. This will help ensure an even, neat look of the grass. Pruning at this time of year will also promote new leaf growth in early spring, as well as greater fullness in late summer.
