Troubleshooting
Clustered Specklinia problems — and how to fix them
Clustered Specklinia (Specklinia aggregata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from waterlogged medium
Consistently soggy conditions without adequate drainage lead to root rot. Use a well-draining medium, ensure the pot has drainage holes, and water only when the top of the medium approaches dryness. Healthy roots are firm and pale green to white; rotted roots are brown and mushy.
Failure to bloom
Insufficient cool nights are the usual cause. Ensure a temperature drop of at least 5-8°C between day and night, particularly in autumn and winter. Inadequate light can also suppress flowering — move to a brighter position or add supplemental grow lighting.
Fungus gnats
Moist, organic growing media attract fungus gnat larvae, which damage fine roots. Allow the top of the medium to approach dryness between waterings where possible, use yellow sticky traps to monitor adult populations, and apply a biological control such as Bacillus thuringiensis israelensis (Bti) as a drench.
