Basil Has Brow Leaves - What can be the reason?

If the leaves on basil turn brown, this is a clear indication of health problems. These can be due to negligence in care, illness, or pest infestation. The following overview shows the direction in research into the causes.

failures in care

Since basil immigrated from tropical regions, the herbal plant is dependent on an adequate location and careful care. The following deficiencies can provoke brown leaves:

  • a location that is too cool with temperatures below 12 degrees Celsius (53F)
  • a substrate that is too wet or too nutrient-poor
  • too small a planter

diseases and pests

If the causes of brown leaves are not to be found in care errors, one of the following diseases or a cunning pest is usually behind it:

  • Wilt or stem rot (Fusarium oxysorum)
  • leaf spot disease
  • aphids
  • dock owl
  • Common Meadow Bugs

Combating diseases and pests with chemical agents is frowned upon when it comes to food in the hobby garden. A wide range of biological control methods are now available, in harmony with nature and for the benefit of health.

I studied horticulture at the University of Guelph and in my free time I plant everything that has roots on a piece of land. The topic of self-sufficiency and seasonal nutrition is particularly close to my heart. Favorite fruit: quince, corner, and blueberry Favorite vegetables: peas, tomatoes, and garlic
