fountain grass

For fountain grass, water when the top inch or 2 of soil is dry. Once a week is usually sufficient, but water more often if the temperatures are high. Water at the base of the plant directly, avoiding wetting the foliage. This will help to reduce the chances of disease. When possible, water in the morning to allow for quicker drying of foliage, reducing the chances of diseases caused by warm, moist foliage remaining through the day and night.

Fountain grass typically requires full sun for 6-8 hours per day. In areas with hot summer climates, the grass may benefit from some afternoon shade to avoid sun scorch and reduce water needs. In cooler areas, the grass can take direct sunlight as long as 8-10 hours per day. Morning sun is especially beneficial for allowing the foliage to dry quickly and avoiding potential fungal diseases. Fountain grass will still survive in light shade, although it grows taller, is more susceptible to fungus, and may not flower as heavily.

Fountain grass should be pruned regularly to maintain its size and encourage new growth. Depending on the size and age of the plant, pruning should be done in early spring or late fall. For young fountain grass, simply pinch back the tips of the shoots to encourage new growth. This should be done every month or 2 during the growing season. For more established plants, it is best to completely cut back the fountain grass in spring or fall. This will help it stay at a particular size and also encourage fuller, denser foliage. Make sure to prune it back to 1 to 2 feet tall for best results. Finally, dead foliage should also be removed as needed throughout the growing season. This will keep the plant looking its best and help prevent disease and pest problems.
