Hi all,

Just made up a batch of home-made 'white oil' after finding the recipe on
Len's site, and have sprayed my new lemon, lime and orange trees after I
noticed they were affected by citrus leaf-miner!

My questions now are ...

How often should I spray with the 'white oil'? and ...

How long should it take to see the end of the leaf-miners if I am vigilant
with the spraying? and ...

Can this oil-based spray do harm to other plants, grasses, etc.?

Cheers,
Mick
