fountain grass

Fountain grass (Pennisetum 'First Knight') should be watered thoroughly and deeply twice per week during the growing season. The soil should be kept consistently moist, but not soggy. During periods of hot, dry weather, water more often as needed to prevent wilting. When the weather cools in autumn, reduce watering to once a week or less. In winter, stop watering altogether until spring.

Fountain grass (Pennisetum 'First Knight') prefers at least 6-8 hours of full sun a day. When planted in a sunny spot, this species of grass will develop a sturdy, strong stem and produce a full, healthy clump of foliage. During the summer months, it will benefit from some additional afternoon shade, especially if temperatures exceed 90 degrees. In the winter, it will continue to actively grow in full sun as long as temperatures stay above freezing.

Fountain grass (Pennisetum 'First Knight') should be pruned annually in mid to late winter or early spring, before the new growth starts to emerge. Trimming back 1/3 of the older foliage each year will help keep the plant looking tidy and prevent it from getting too tall and leggy. Pruning this particular grass to 6-12 inches in height can help promote increased bud set, which will lead to fuller and lusher growth over the summer and fall months. Be sure to discard the pruned foliage instead of composting it, as it may contain invasive weeds or plant diseases.
