Lemon Plant

[Ric.ror]

I have just repotted a very healthy lemon plant into a much larger pot. I have left approx 1.5 inches at the top so I can top it off with something that will prevent the soil attracting those pesky small flies- should I pop a layer of fish tank gravel topped off with the white stones I used in the base of the pot for drainage

TIA

You could try some sticky yellow tags in the pots, available online

I’ve got some of them but I’d prefer to stop them laying their eggs in the soil

I've read that diatomaceous(sp?) earth works and stops females from laying eggs.

I am just wondering if coffee grinds would do the trick
