Full Description

Acorus Ogon is a dense, spreading sedge (grass) growing to 12 inches tall and is grown for its foliage effect. Features grass-like, stiff leaves (1/2" wide to 12" long) which are dark green in the center with clean white borders. The moderate spreading habit of this sedge (most sedges are clump-forming) facilitates covering woodland areas as a groundcover. Brownish flowers in late spring are insignificant. This sedge is evergreen in the South, maintaining a good appearance in both summer and winter, but is not evergreen in northern areas, although some foliage color will persist through the winter, but it will need cut back in the spring. Acorus Ogon will brighten a shady area. Adds soothing movement to the garden when foliage dances in the breeze.

How to Prune Acorus Ogon?

Remove the old flowers of Acorus Ogon as they become brown and unattractive. This procedure, called deadheading, encourages the Acorus plants to produce new foliage, keeping your plant looking attractive throughout the season. Cut back yarrow to within 6 inches of the ground after it has finished flowering. In colder northern climates, cut it back as one of the last chores in your garden before the snow flies. In warmer climates, cut it back in the spring before it begins to grow but only if necessary due to winter damage. Cutting back will promote new growth, giving you a healthier plant.

How to Fertilize Acorus Ogon?

Feeding your plants is probably the single most forgotten part of growing healthy long lasting plants. We recommend feeding your Acorus Ogon in the very early spring and again in mid summer after all new growth has hardened off and it begins to set flower buds. Bio-tone starter fertilizer is the best product to use at the time of planting. Our ideal fertilizer schedule for you to use is as follows. Apply an early spring fertilizer with a product such as Espoma Flower-tone at the recommended rate this will give the plant a boost of nitrogen and potash that will be needed for healthy foliage and stem growth. Follow this up with another early summer application of Espoma Flower-Tone, this will again provide the necessary nutrients to promote a flush of beautiful flowers. Espoma products are easy to use, just sprinkle around the base of the plant and water it in. Be careful with products such as miracle-grow as these products can burn newly planted plants when not used at the recommended rates. Slow-release fertilizer can help prevent rapid soft growth that is vulnerable to diseases and insects.

What is the Best Mulch to Use for Acorus Ogon?

We highly recommend that you mulch your Acorus Ogon with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the  mulch and the stem or base of the plant.

How to Water Acorus Ogon?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Acorus Ogon a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks.
