Hi ZenMan and Sue,
I used garden soil.
Weeks ago, I placed those zinnias in shade. That's why my zinnias are leggy. But now, I have placed them in full sun (outdoor).
And I have some problems with leaf miner and white flies? Could they be the problems? I placed some yellow traps. And I also removed all leaves infested with leaf miner. But I think the traps got most of them. I shake the zinnias every morning to see whether there are white flies flying or not.
Thanks
