As ornamental grasses are very low-maintenance, fertilization is not normally necessary. If your grasses are looking shabby, add some mushroom manure to your soil to give them a boost.
How to Plant:
When planting ornamental grass make sure they are planted slightly raised above grade to prevent root rot. Remember most will survive drought conditions better than wet conditions.
When to Plant:
The best times to plant your ornamental grasses are spring and fall. It is also acceptable to plant in summer, just make sure they are irrigated well.
When to Prune:
To rejuvenate your grasses, prune back in early to mid spring. The pruning will invigorate the grass and lush new growth will emerge in abundance.
Diseases and Pests: Ornamental grasses are notoriously disease and pest free. Many are also deer resistant.
