Pampas grass needs sufficient nutrients for its rapid growth. We will tell you what you need to consider when fertilizing pampas grass. The pampas grass (Cortaderia) is high, even arrogant. The fast-growing plant becomes really impressive in autumn when the large inflorescences appear. In order for the pampas grass to develop well, a balanced nutrient supply is of course essential.
Pampas grass, as its name suggests, comes from the vast grasslands of South America. There, it feels especially comfortable along streams or other humid, yet very sunny locations. Underground, the grass forms a rhizome – a survival organ in which it can store nutrients and energy. The soils of the pampas are well suited for this purpose because they are deep and rich in nutrients. And “nutrient-rich” is also the keyword when it comes to fertilization.
Fertilizing pampas grass: When is the right time?

Pampas grass starts growing in spring after its winter break. This is also the best time for fertilization. However, fertilization in late summer would damage the frost-sensitive plant, as it would not be able to ripen properly before winter.
What should pampas grass be fertilized with?
In the pampas there is a very special type of soil: it is very deep and mainly mineral, but due to the high activity of the soil organisms it is strongly interspersed with hummus. If you want to do something good for your pampas grass, you should follow this example. Organic fertilizers that promote soil life and humus formation are therefore best suited.
Also, beware of too much nitrogen. Although this nutrient is essential for every plant, an overdose can be harmful, especially for tall grasses like pampas grass. The grass then loses stability and sturdiness and becomes more susceptible to cold and frost.
Keep in mind that pampas grass not only thrives on its favorite soil but is increasingly colonizing areas that have been disturbed by humans, such as old industrial sites, railroad tracks, or roadsides. The soil there is often sandy and less nutritious. Nevertheless, the grass grows excellently even on these soils and has become an invasive species in large parts of Southern Europe without any fertilization.
Very regular fertilization is therefore not important for pampas grass. It is extremely easy to care for and can also manage with fewer nutrients. However, unlike in the wild, you will most likely remove the dead leaves, so you regularly remove nutrients from the cycle. This loss has to be compensated from time to time.
Mineral Fertilizer For Pampas Grass
Mineral fertilization is actually not in the nature of pampas grass. In its native land, it uses the nutrients that are released during the decomposition of organic material. This happens gradually over the summer when it becomes warm and humid. However, mineral fertilization is usually readily available and does not last long.
Soon the plant will need to be fertilized again and so you as a gardener are constantly busy fertilizing all kinds of plants. If you want to use mineral fertilizers, it is better to use depot fertilizers with moderate nitrogen content. This is easy on your nerves as well as on the groundwater and also meets the needs of the plant.
Fertilize pampas grass with household remedies
Their nutrient-rich legacies can be found everywhere. If you want to fertilize your pampas grass in a very special way, then keep an eye out for an alpaca keeper in your area. Surely he will gladly provide you with alpaca manure. And by the way: The dung of this camel species is probably one of the highest quality natural fertilizers, not only for pampas grass.
Fertilizing pampas grass – a brief summary of the most important facts:
- Thrives naturally on nutrient-rich and deep soils with high humus content.
- Can also develop very well on sandy and disturbed soils.
- Fertilization from time to time makes sense because by cutting back the pampas grass stalks nutrients are withdrawn from the cycle.
- Fertilization in spring.
- Use only fertilizers with moderate nitrogen content.
- Prefers compost, alpaca manure, or organic fertilizers.
