How to Plant Your Dwarf Pampas Grass
Some basic information before beginning the process of planting: ideal location should be a top priority. Dwarf pampas grass can survive any zone with year-round warmth with plenty of sunlight. Additionally, a dwarf pampas grass seed should be sown in the winter for a successful bloom.
Spot Selection and Soil Type
The dwarf pampas grass has no preference if you place it to grow or thrive in a pot or the ground. You just have to make sure that the soil is adequate. If you select a pot for planting, make sure that is at least 20 inches in diameter.
To find the right spot in your garden, you should also take sunlight into account. Just like regular grass, dwarf pampas grass needs full sun to grow into mature height. Even if you have your dwarf pampas grass in a container, you should keep the grass in the light for as long as the sun is out.
To reach a healthy, mature height, the grass needs to be placed in the proper soil. Potting soil works well for the plants in pots, but adding a bit of compost can make the bloom more successful. Making about one-third of the soil organic can support the grass to look healthier and more beautiful. Overall, the plants work in all sorts of soils including sandy, dry, and clay.
Fertilizer and Time of Planting
For fertilizer, you can use an all-purpose 10-10-10. It has lots of nitrogen and other essential nutrients for your grass. The best time to add fertilizer is once you plant the grass. You can continue to add fertilizer as needed, but it is best to do it every 30 days or so.
Adding Support
Before the grass can grow nice and tall, it may need some kind of support. You can add a rod or some type of stake, fix it to the ground, and carefully tie some of the grass blades to it. If you have to resort to supporting the plants, don’t worry because many dwarf pampas grass must go through the same process before reaching their full, mature height.
How to Care for Dwarf Pampas Grass

Sunlight and Watering
Pampas grass requires full sun, which can affect how much hydration it needs. Most plants in a warm zone need more frequent watering to last them through the spring and summer. Since these plants fully bloom in the late summer, H2O is a critical factor, even in the spring. You may also want to show some love with water after initially planting the seeds in winter.
The key to a successful bloom is healthy roots. One thing that dwarf pampas grassroots need is routine watering. Despite being drought tolerant, these plants must have regular water, preferably weekly, through the spring and into the summer when they reach their full bloom.

Pruning

This also helps when planting strong stems. Additionally, in the right zone, this grass can grow as high as 6 feet. Therefore, if 6 feet is not the ideal height, pruning is a must, and it is totally healthy. Additionally, if it gets too wide, you can cut the plant back just a bit and have a gorgeous plant.
