Umbrella fir gets yellow needles

The umbrella fir suffers from drought

One of the main reasons why the Umbrella fir yellow needles can be dryness. Umbrella firs need a moist subsurface and cannot tolerate drought. Did you water too little and did you experience heat waves? Then don't be surprised about yellow needles... Especially when the umbrella fir is in the bucket, it should be watered regularly.

Indication of a nutritional deficiency

The second main reason for yellow needles is a nutritional deficit. The umbrella fir can lack the following nutrients:

• Potassium: Often deficient in sandy-dry soils
• Nitrogen: Add peat to the earth so that nitrogen can be better bound
• Phosphorus: Provide with fertilizer containing phosphorus

Rot in the root area

Furthermore, a yellow needle dress can be caused by putrefaction. This is caused by moisture in the root area, which accumulates over a long period of time. This often happens in heavy and loamy soils. Prevent this by doing your planting

humus or add sand to the earth.

Yellow needles caused by stress

Stress can also lead to yellow needles. Stress arises for the umbrella fir, for example, from too much sun and the associated heat in summer. The direct midday sun in particular can damage it.

In addition, a replanting action, severe frost breaks and a pest infestation mean stress for the umbrella fir. Sometimes pests appear Spider mites on. They especially like to colonize young specimens. They suck their needles on the underside, whereupon they turn yellow.

Immediate action against the yellow needles

Depending on the cause of the yellow needles, you should now take one or more of the following measures:

• discolored parts cut off
• Mulch the soil
• with pine fertilizer fertilize (better less and more regularly)
• water abundantly
• Check for spider mite infestation
• spray from above with heat
