I wuld like to plant hameln grass or something similar around my storage shed as a border plant. I live in zone 7 (Tulsa, OK). Can I plant this type of grass in September? Or are there other grasses not over 3 feet tall that would work?
Generally these are planted in late spring or early summer, as they are considered warm-season grasses and the roots will grow only in warm soil. Planting too early in the spring may cause the roots to rot; however, planting in the fall may not allow the roots to grow enough to establish before the cold and wet of winter.
Last spring we planted Hameln pennisetum and it grew and bloomed nicely. This year it came back but none of the plants bloomed. Not enough sun? It's in a pretty sunny spot. Any ideas why it did not bloom this year?
Could be a few reasons, growing conditions or even to much Nitrogen in the soil.
Using a Phosphorous rich fertilizer such as Bone Meal can help boost flowering.
Here is a link to refresh you on the care requirements.
I have 40' of Hameln grass planted on a bank along my driveway. The plants are about 5 yrs old and are about 1' wide. Several of the plants are rotting from the center of the plant out. We trim the plants each year in the spring before they start growing to about 4". We try to remove the dead stalks and the rot each spring but it is getting progressively worse. We do mulch with bark mulch. Prior to planting the Hameln grass, the bank was planted with spirea which died off due to fire blight. We live in VT in zone 5. What can we do to improve the health of these plants?
Regular division of ornamental grasses should be done either every year or every other year to help prevent die back of the center of the grass.
