Gray mold on the Korean fir
Gray mold is a disease caused by fungal pathogens that is most common in the Korean fir. Dying young shoots are a clear sign of disease. Mostly unfavorable living conditions have favored the disease. For example:
- too dense planting
- resulting in insufficient ventilation
- a heavy, compacted soil
Generously cut off all infected parts and dispose of them as residual waste. You can then use a commercially available preparation to defeat the disease without leaving any residue.
Deficiency symptoms lead to needle loss
If the Korean fir gets brown needles or loses them, it doesn't have to be a disease caused by pathogens. With increasing age and size, every fir tree burns from the inside because parts of the needle dress are permanently shaded. If needles also fall, consider the following causes:
- Lack of nutrients, especially magnesium
- prolonged lack of light
- Frost damage or drought
- sunburn
Tips
Do a Soil analysis to reliably determine any nutrient deficiency. Only then should you be reluctant to use the Epsom salt fertilize. Fertilizing without necessity would rather exacerbate the problem with the needles.
Pests are common culprits
Pests, too, can cause symptoms like yellow needles, which remotely we may prematurely mistake to be a disease. If you take a closer look at the tree, you will surely discover evildoers present. The healthy growth A Korean fir is mainly affected by mealybugs and bark lice.
