Reasons for a needle discoloration of the jaw
If your jaw gets brown needles, possible causes are:
- a natural process
- a disease infestation
- a care mistake
- Yellow needles and the jaw dropping them - that's behind it
- Overview of different types of pine tree
- The pine blossom
Recognize and fight diseases
The most common triggers from the areas mentioned above are discussed below:
- the natural change of year
- a change of location
- unsuitable soil
- Frost dryness
- Calcium chlorosis
- Pine dump and dieback
- the jaw tensioner
The natural change of year
Although the pine is evergreen, it does not keep its needles forever. Every year it hardly noticeably loses its old leaves. However, every two to ten years this process takes place to a particularly large extent, in which the needles first turn brown. In this case, however, there is nothing to worry about as it is a completely natural process.
A change of location
Pines form an extensive and deep root system that is injured when moving. From the age of five, the conifers recover only poorly from a change of location. The severed roots can no longer adequately supply the needles, they turn brown. Generous irrigation helps here.
If the deep taproot encounters encrusted soil, there is a risk of both root rot due to waterlogging and undersupply. So work a layer of compost or mulch into the soil before you plant your pine.
Icy winters affect the pine because it cannot compensate for its loss of moisture by absorbing water from the soil. When it is frosty, you have to give her the water she needs.
Calcium chlorosis is an iron deficiency in your jaws. Use Epsom salts to ensure that the soil pH is around 5.5-6.5.
Pine dump and dieback
If the discoloration of the needles is not due to a care mistake, a fungal infection is possible. The complete removal of all infected branches helps against the pine chute and the death of shoots.
The jaw wrench
The female butterfly of the pine moth uses the jaw to lay her eggs. As a result, the larvae feed on the needles, which then turn brown. With a treatment with rapeseed or neem oil you can put the pest on the run.
