Caring for ornamental grasses

There are 5 aspects involved in care for ornamental grasses, they are - fertilizing, watering, weed control, winter protection and division.

Fertilizing

The need for fertilizing ornamental grasses is relatively low. By keeping the levels of nitrogen content in the soil low you can prevent the foliage from getting too lanky and flopping over. One pound of 10-10-10 fertilizer to a 100 sq feet area of grass should be sufficient or in other terms, one quarter cup per plant should be enough.

When is the right time to apply fertilizers?

The best time is at the start of the growing season, in spring. If you apply some slow release fertilizer like osmocote at the start of the season, it should be sufficient to take care of the nutrient requirement of the grasses till summer. Be sure to water in deeply when you fertilize and do it on a cool day.

Watering

Water deeply during the first season of their growth, in spring. Deep watering ornamental grasses to depth of about 2 inches at the start would help them develop good rooting. Once the grasses are established they will have minimum water requirements, you would just need to supply water during the drought spells. If you don't desire a faster growth rate you should reduce the supply of water. The watering requirements will also depend directly on factors like the soil quality, the grass species and the amount of heat in your region.

Weed Control

You might need to cultivate around the grass plants to control a weed infestation. Using a sharp garden hoe is perfect for this purpose. Tilling the soil well before planting would reduce the number of weeds you will need to contend with. Another useful tip would be to place a mulch around the grass to reduce the onset of weeds. You can use straw, cocoa shells or gravel, in some cases, for mulch. Another advantage of using a mulch is that it keeps the heavily reseeding grass types in check.

Winter protection

The good news is that you need to do nothing as a winter protection measure. The grasses should be left alone and be allowed to winter. They look quite beautiful with the de-colored foliage and it also helps insulate the crown of the grass from the harsh frost. Come spring, you should cut the foliage to about four to six inches so that growth resumes from there.

Division

You would need to divide the plant up if the centre starts to die out. Use a shovel to split the grass at the centre and divide it into two parts. You can grow these separated parts in different areas of the garden or at the same spot. Division is sometimes performed in spring before the growth resumes, you can also employ division in the summer when you notice the centre dying out. It can also be done in the fall once the growing season is over. With experience you will realize that dividing is an important aspect of ornamental grass care.

You can employ ornamental grass dividing simply to replant them in a different location. Look at it this way, division allows you to get two plants of grass instead of one. Check out this illustrative video on how to employ ornamental grass division (this video is from 5min.com)

We hope you enjoy the experience of planting ornamental grasses in your garden, just be cautioned that you will get addicted to the grasses and you won't be able to stop yourself from trying out new varieties ever growing season.
