Lamp cleaner grass turns yellow »Causes and measures

Attractive autumn colors

The lamp cleaner grass is one of those ornamental grasses that change the leaf color with the seasons. In autumn, the golden-yellow stalks set wonderful accents.

Yellow leaves in the middle of summer

If only a few leaves change color during the main growing season, don't worry, as it's a natural process. You can easily cut out these parts of the plant with scissors.

However, if all the foliage turns yellow prematurely, this is a sign of a care error. Either you have watered the plant too seldom or the soil is too compact.

Pour enough

• Lamp cleaner grass in the bucket need water supply whenever the top inches of the substrate feel dry.
• Pennisetum cultivated in the garden should also be watered as required. Daily watering may be necessary in hot summers. Pour preferably in the evening hours.

Bad soil quality

If the soil is too compacted and the water cannot run off, this leads to root rot. The storage organs can no longer fulfill their task. Even when sufficient moisture is available, the leaves of Pennisetum initially turn yellow and then dry up.

If you dig up the pennon cleaner grass, the roots are usually already dead, brown and mushy. If the entire root system is not yet infected, you can try to save the plant:

• Lift the pennisetum out of the earth.
• Cut all infected parts of the root back into healthy tissue.
• Loosen the soil with sand and / or gravel before replanting.
• Provide a drainage layer in the planting hole for good water drainage.

Chlorosis

If the leaves of the lamp-cleaning grass turn yellow before the start of autumn, there may be an iron deficiency. This element plays a central role in the molecular structure of the green plant pigment chlorophyll.

Provide a remedy regular fertilization with a commercially available fertilizer for green plants. Iron is added to these preparations in the optimal amount for plants.
