Why does your Mini Rose Hot Jewel have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, which lay eggs in the moist upper layers of soil. Their larvae feed on organic matter and can damage the delicate root systems of miniature roses, potentially leading to stunted growth.
Miniature roses are highly susceptible to fungal growth when the potting medium remains saturated. Constant dampness provides the ideal breeding ground for fungus gnat larvae and promotes soil-borne pathogens.
If the 'Hot Jewel' rose is planted in a pot with overly rich, decomposing compost or heavy peat, it attracts gnats looking for breeding sites. The larvae thrive on this decaying organic material.
