All about Miscanthus giganteus
Speaking on the species of the genus of Miscanthus (also: elephant grass or Chinese reed, Chinese grass), we usually mean very fast-growing, winterhardy, deciduous bunch grasses (no bothering offshoots like bamboo).
Along with ornamental varieties of miscanthus, the prevailing sort in agriculture or in the area of renewable energy is Miscanthus (sinensis) x giganteus that we would like to introduce to you in more details in the following Miscanthus Newsletter and in further information!
Maturity Ratio of Elephant Grass
Starting from the end of September, reserve store moves to the rhizome system, especially in September and October. For this reason, we would not recommend autumn planting in all conscience, since miscanthus plants are usually completely mature only in December.
(See also Miscanthus rhizomes, rhizomes) This a bit cumbersome term of “rhizome” can also be translated as “a piece of root”, “undercuts”, or “root cuttings”. It involves thickened roots of perennial grasses, such as elephant grass, which can be used for the propagation of this plant. Simply, such a propagation via rhizomes can be described as follows: Excavating a 2-4-year-old elephant grass-stick Such a […]
Miscanthus is also naturally and ideally suitable for alternative pellets production. At the same time, Miscanthus has advantages over conventional sawyer materials that are normally used for production, but it also has disadvantages. In terms of energy input/output, Miscanthus pelleting is disadvantageous, as compared to Miscanthus briquetting. However, for the sake of usability for as […]
The confusion with many names that Miscanthus has in the German language continues partly in botanical names. The energy crop Miscanthus x giganteus is genetically similar to Miscanthus sinensis that generally comprises many ornamental Miscanthus varieties. For example, Miscanthus sinensis “Strictus”, “Malepartus”, “Small Silver Spider”, or “Far East”; Although the term of “elephant grass” for […]
Soil value, watering and local temperatures influence strongly the yields from planting miscanthus. Dry mass yields (DM yields/air dry tons*): • 4.000−7.000 kg/ha in the 2nd year • 12.000−20.000 kg/ha starting from the 3rd year For the water content of 14 %, you can expect to harvest an average yield of 19,000 kg/ha (corn/maize fields).

Planting Material: Miscanthus Rhizomes
When buying, please make sure that the tissues are healthy and firm! Cut or broken locations should be whitish, light-colored. Rhizomes that you receive from us are about 7−15 cm long and usually have 4 or more well-formed eyes. As a rule, they are harvested and subsequently sorted manually on the same day, and temporarily […]
Planting Miscanthus Planting time: April-May Recommended with potato cultivation machine (slate shaft 15-20 cm!), it is also possible to do it manually on smaller areas Place rhizomes at a depth of 4 cm (in light soils) to 8 cm (in heavy soils) and then roll over/compress well 1×1 meter planting distance Aquiferous arable soils with […]
Planting Miscanthus / Elephant Grass
The rhizomes are very sensitive to dry air, so they should be planted as soon as possible upon unpacking (planting time: mid-April to at latest mid-May). Optimal soil temperature for planting is 10°C. For too early planting, there can be a threat of late frosts, while for too late one, there can be unusually high […]
Preparations for Planting Miscanthus / Elephant Grass
To be prepared for planting, the field should be ploughed to a depth of at least 20 cm in autumn. It should be ensured that no large organic amounts of previous crops are incorporated, since the free-releasing nitrogen inhibits the maturation in autumn. one-year-old miscanthus plants start storing nutrients in the rhizomes very late in […]
Soils and Climate for Chinese Reed
Humous clay soils with good irrigation are the best for the cultivation of elephant grass. Unfit are very heavy soils and such ones that tend to compaction. The soil should be wet, but it should not be water-logged at the depth down to 1 m (pH 5−8). Goudweeds should not play any dominating role. The […]
