Reproduction and planting of pennisetum in open ground
The seeds are sown usually in the spring, at the beginning of May, when the weather becomes favorable and warm.
- First dig up and level the area for disembarkation. Usually this is the space along the fence.
- Then the seeds are scattered and slightly buried using a rake.
- The resulting flowerbed is watered regularly so that there is no stagnation.
- When the first seedlings appear, they are removed so that the distance between the bushes is 70-80 cm.
Pennissum seedlings are prepared in advance in February-March and planted in May.
- Prepare a nutritious soil based on peat.
- In each individual container, drainage holes are made and no more than 2 seeds are placed.
- They create greenhouse conditions: they spray the soil every day, cover the container with foil, maintain bright lighting, room temperature and ventilate regularly.
- Shoots rise in about a week.
- Remove the shelter and install additional lighting (phytolamps).
- When the shrub reaches 10-15 cm, it is planted in open ground.
Pennisetum is propagated vegetatively. Spend every 5-6 years, while the air temperature should not be too high.
- Young sprouts, along with the formed root system, are carefully dug up so as not to damage the plant.
- The soil is loosened and fertilized with peat, sawdust or humus.
- The root is planted and completely buried, leaving only the green part above the ground.
- Watered as it dries for 2-3 weeks, until the bush takes root.
- Young pennisetum will bloom in 1-2 months, then watering is completely stopped.
It also propagates by self-seeding and does not require outside intervention. This occurs in perennial shrubs.
Care for the penisetum in the garden
In order for the cinnamon to grow healthy and delight with its extraordinary inflorescences, it is necessary to properly care for it.

Temperature | Planted in May, when the air had not yet had time to finally warm up, but there was no possibility of frost. The shrub is unpretentious, but it does not tolerate too hot weather and needs to be thoroughly moistened. |
Watering | No additional required. The soil is moistened only with prolonged absence of rain or too hot temperature (July-August). |
Fertilizers | Use mineral top dressing containing nitrogen, potassium or phosphorus. Also used organic, for example - manure, humus. They are fed Kristallon, Plantafol, Ammophos, Kemira. |
Transfer | Carried out only in extreme cases (for example, during wintering), since the condition of the shrub deteriorates and it can die. |
Winter | Perennial species and varieties are covered with a special flooring, and the soil around the plant is sprinkled with dry foliage or needles to ensure the safety of the root system. The stems are not pruned - this serves as additional protection for the penisetum. In the spring, when the snow is falling, the dried ground part and the shelter prepared for the winter are removed. If the plant is annuals, it is planted in advance in a large container and, with the onset of frost, brought into a warm room. |
