Why does your Brassica Coral F1 Feather Prince have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The larvae of these flies live in moist organic matter and feed on the fine root hairs of Brassica plants, which can weaken the plant's structure. The adults emerge to lay eggs in the top layer of soil, often attracted to the high nitrogen content used for ornamental kale.
While typically associated with ripening fruit, these flies can be attracted to the decaying organic matter or fermentation occurring in over-watered brassica pots. They are often mistaken for pests of the plant itself when they are actually attracted to the micro-environment.
These are closely related to fungus gnats and thrive in the consistently damp, cool environments that 'Feather Prince' kale prefers. They specifically target decaying plant debris around the stem of the brassica.
