Fungus Gnats

These small flies thrive in the moist, organic-rich substrate often used for Graptoveria. The larvae live in the soil and feed on decaying organic matter and occasionally fine root hairs of the succulent.

Very Common

How to confirm: Place a yellow sticky trap near the base of the plant to see if adult flies are attracted to it.

Soil Moisture Imbalance

Frequent watering or lack of drainage in Graptoveria pots creates the damp environment necessary for fungus gnat breeding cycles. Succulents like 'Fanfare' require a drying cycle between waterings to prevent this issue.

Very Common

How to confirm: Stick your finger two inches into the soil; if it feels damp even though you haven't watered recently, moisture is too high.

Decaying Organic Matter

Old, uncomposted potting mix or decaying fallen leaves on top of the Graptoveria can serve as a breeding ground for flies. The presence of too much peat moss in the mix can also hold moisture too long.

Common

How to confirm: Inspect the top layer of the soil for any decomposing plant material or old mulch that needs removal.

1 Remove the top layer of decaying organic matter and fallen leaves from the soil surface to eliminate the breeding ground for the flies.

2 Repot the Graptoveria in a fresh, well-draining substrate and consider adding perlite to improve aeration and prevent moisture retention.

3 Deploy yellow sticky traps near the plant to capture the adult flies and disrupt their life cycle.
