Several of my Magellan transplants have these holes. What's causing this & how do I treat it?

| i dont understand .. are they transplanted already .. or are they potted right now ... tip the pot over .... and shake the plant into your hand.. and find out what is hiding in the soil .. if they were out in the garden .... i would suggest slugs/snails... ken |

| It could be flea beetles. You might be able to catch them in the act of eating a small hole in a zinnia leaf, if you observe your zinnias from time to time. Flea beetles are skittish, and can jump like a flea, so hand-picking them is out of the question. I had a flea beetle outbreak in my zinnia garden a couple of years ago, and our guineas made short work of them. I have no idea what caused the outbreak. It was sort of like a population explosion. We live in a rural area, surrounded by farm fields, and we have had some interesting insect problems in the garden. Occasionally blister bugs would fly in. They seem to have a taste for zinnia pollen florets. Oddly, nine-spotted cucumber beetles were something of a problem in my zinnias. I hand picked a few of them. I have some forceps that I use to grab blister beetles. I don't know how seriously to take that "blister" in their name. I suspect it is over-rated, but I could be wrong about that. That flea beetle damage doesn't look too serious. Minor cosmetic damage. If it gets no worse than that, I think you could just ignore the problem. This could be a case of, "If it's not broke, don't fix it." ZM |

| Thanks ZM ! I was hoping you'd chime in on this!Pics in the link peggiewho posted sure look like it could indeed be the flea beetle. I'll monitor the damage more closely before doing anything too radical..... Thus far,it seems to be confined to a small number of my 200 transplants.... |
