Wrong location

Pampas grass likes it warm and sunny. If the perennial does not get at least four hours of direct sun per day, flowers will not develop. Therefore only plant pampas grass in a sunny spot. Provide wind protection so that the fronds do not break later.

The ornamental grass prefers dry soil. It does not tolerate waterlogging at all. Loosen the soil deeply before planting. Mix very dense soil with sand and small stones to make it more permeable.

Incidentally, light slopes are very suitable, as the water drains off easily and does not build up at the roots.

Wrong care

Very often the pampas grass does not bloom because of one or more mistakes in care. Even if the perennial likes it dry, it must not dry out completely. Pour more often once when it is hot. Pampas grass in the bucket must be regularly supplied with water.

A plant that grows as fast as pampas grass needs a lot of nutrients. It is best to spread compost around the perennial every few weeks and rake it slightly. Otherwise fertilize with liquid fertilizer for ornamental grasses.

Pampas grass is cut in the spring. You need to be careful not to injure the young shoots. If they are damaged, the perennial will not set any flowers.

Male plants bloom only a little

If the pampas grass is in a favorable place, it has enough nutrients and moisture, but is still not blooming, you may have grown a male plant.

Pampas grass is dioecious, so there are male and female plants. While female plants produce many of the decorative fronds, the flowering of male plants remains rather sparse. Unfortunately, nothing can be done about it.

Make sure you only plant female pampas grass. You should therefore also not sow plants from seeds you have collected yourself, as you do not know whether a male or female plant will emerge. If you bought seeds, there is a good chance that you will only grow female plants.

Tips

Pampas grass blooms late in the year. Some varieties start to bloom in July, while others don't start to bloom until September.
