variegated bulbous oat grass

Variegated bulbous oat grass needs to be watered about once a week, or whenever the top of the soil feels dry. Allow the water to fully saturate the soil, and be sure to not let the soil become soggy. During the peak growing months of the summer, it may need to be watered a little more often in order to keep the soil moist. The amount of water should be enough to keep the soil just slightly moist, but should not be excessive.

Variegated bulbous oat grass (Arrhenatherum elatius var. bulbosum 'Variegatum') requires full sun to partial shade. During the warmest part of the day, it enjoys 6 to 8 hours of direct sunlight. During the cooler seasons, it tolerates 4 to 6 hours of sunlight a day. The plant should be protected from excessive heat and direct sunlight during the hottest part of the day.

Arrhenatherum elatius var. bulbosum 'Variegatum' is a type of grass that should be pruned in early spring, before the new growing season starts. Pruning should be done sparingly, cutting back the stems to a maximum of 25 cm and removing dead or damaged leaves as well as seed heads. Variegated bulbous oat grass will generally flower from mid-summer onwards, which is when the plants begins to increase in size. After the flowers fade away, the foliage will begin to turn brown. This is the time for pruning back the plant to maintain its shape and size. To avoid damaging the fleshy bulbs, cut back the stems to the ground or just below the surface. Pruning back this plant should be done no more than once or twice per year.
