Detailed discussion on how often to water fountain grass

Fountain grass (Pennisetum Alopecuroides) is a popular ornamental grass that can add charm and vibrancy to your outdoor space. These plants can grow up to 2-3 feet tall and are usually drought-tolerant. However, during the hot summer months, it is crucial to provide them with enough water to prevent wilting and ensure that they maintain their lush green color.

Here’s a detailed guide on how often to water fountain grass:

How much water do fountain grasses need?

The frequency of watering fountain grass will vary depending on different factors such as the climate, the soil type, and the size of the plant. In general, newly planted grasses will require frequent watering to help establish their roots. On the other hand, mature fountain grasses can tolerate hot and dry weather and do not need as much watering as immature ones.

When should you water fountain grass?

Water fountain grass early in the morning or late in the evening, as the water will have time to soak in without quickly evaporating from the leaves. Avoid watering during the hottest part of the day since the water can scorch the leaves.

How to water fountain grass

To water fountain grass, use a watering can or a garden hose and aim the water at the base of the plant. Do not wet the foliage as this can lead to fungal problems and damage the leaves. The soil should be moistened to a depth of six inches.

How often to water fountain grass in summer

In summer, when temperatures are high, and the air is dry, you should water fountain grass at least once a week. However, if the weather is especially hot and dry, you may need to water more frequently.

How often to water fountain grass in winter

During the winter months, fountain grasses are dormant, and you should water them once every two to three weeks. Overwatering during this time can cause root rot and damage the plant.

Signs of under or overwatering

It’s essential to monitor your fountain grass to ensure you are watering it as necessary. Signs of under watering include:

  • Wilted leaves
