AusBonsai

Hi all,
I got these fungus on all my garden plants bonsais and training pots, i did search on the net and found they call genat fungus, and they coming because of the moisture of the soil! I got oil neem to control it but not works properly, what you guys use for these, they seems over the soil mostly,
Any advice appreciated
Joe

Not fungus but small flies called "fungus gnats". Not sure that the adults do any harm, apart from being annoying in large numbers. The juveniles which are small maggots in the soil will eat plant roots but this is probably only an issue for small seedlings/cuttings. These are common if you have very damp potting mixes with lots of organic material. You can add more inorganic material to your soil and also let it dry out a little more to make it less attractive. Other websites indicate beneficial predators can help as well as just reducing the population with some sticky yellow traps.
