Hi Fran,
It was so kind of you to post that list of plants that repel a variety of insects. Hope you were able to cut and paste the list and didn't have to type it all. I am going to print it for easy reference. Thanks so much!
Tina

I believe you're looking for "Bouquet" Dill, although one person over on the butterfly forum gives "Fernleaf" two thumbs up.

Trowelgal, that's a good list, but if you have any questions about specific plants and predators, just do a google search for "companion plants and xxxxx" Another good resource is the library. See if you can find these two books.

# Carrots Love Tomatoes: Secrets of Companion Planting for Successful Gardening by Louise Riotte

# Great Garden Companions: A Companion-Planting System for a Beautiful, Chemical-Free Vegetable Garden by Sally Jean Cunningham

I've got them both and use them for reference when planning my garden.

Wow, Fran. That is a really handy list! Thanks for posting it. I, too, am going to print it off and keep it handy. Hmmm. OK, now I have to wintersow some dill. Hmmm, OK, now I have to find some dill seeds...and then find another jug. *sob*

Kris (wondering what she did during winter for decades before she found winter sowing...!)

I have tansy growing near my roses, while we still have Japanese beetles flying the damage is nowhere serious as it happened before tansy. I plant dill and it reseeds throughout my garden anyway as I like it.

Nice list! I have some of the plants on there already. I am doing a trade for some dill. I just love it! I did not think it would repel insects. I guess I need to get more of it!

Karen

Now I want to plant even more pungent herbs. You are probably right about the name of the dill, it is probably fernleaf or bouquet. Thanks for the sites Token, I'll look into those too. Another flower I used to raise was cosmos but the cucumber beetles ate those too so I quit Cosmos. Maybe I should try them again this year with lots of pungent herbs at their feet. Since I keep an organic garden I love any "natural" idea for repelling bad insects and ideas for attracting the beneficial variety. Keep your ideas coming, we can all benefit.
Tina

Tina,

I copied and pasted the list from a post on another forum on GW.

I want to add a plant to the list that I personally think should be on it.

4'oclocks should be there. Since I was a little girl, 4 o'clocks where the mainstay around my grandparents roses and anything else those ugly green beetles would attack.
Never any damage to the roses or other plants except the 4 0'clocks. The stupid beetles would chew up some of the 4 o'clock leaves and we'd find tons of dead JP around the 4 o'clock plants and on the ground underneath them.

Many of them where grown in 10-12 inch pots, 1-2 plants in a pot and grandma would move them around to various spots if she spotted the JP around.

The 4 o'clock will just keep on growing more and more new leaves and bloom beautifully, even with holes in some of the leaves and JP would be history.

Have been using them myself, in pots, for 28 years and have no JP problems.

Recently doing a google search, I read that the leaves of the 4 o'clocks are poisonous to the JP. They are dumb enough to continue eating the leaves and die, and apparently when the JP are dead and dying, it keeps the others away from the gardens.

Now for the list and plants that I've tried on it that have worked for me.

BASIL,
now know why the number of mosquitos by my front steps where very far and few between. 12 basil plants did the trick.
What I don't know though, is if it is only sweet basil or any kind of basil. I had 5 sweet basil plants and the rest where thai, lemon, lime, cinammon.

DILL
That explains all the hundreds of wonderful insects that where around the yard.

GARLIC?
well had plenty of garlic chives and the aphids where no where to be found. they smell just like garlic so am going to try garlic chives around my lupin and see if that keeps the aphids away.

MARIGOLD,
Another old time favorite insect repellant from my grandpa. All his tomatoes and he had well over 100 plants on the veggie farm, had marigolds planted around them. The one thing he never worried about with them was any insect damage and he told me the reason was "they don't like that stinky smell of the marigolds".
I've used them around my toms for 28 years. I grow them in huge pots and put a dwarf marigold seedling inside each pot, right at the edge of the pot.
Never have had an insect problem with the toms, except the one little tiny tim that didn't get a marigold. That one ended up with the dreaded hornworm.
Learned my lesson real quick and never made that mistake again.

NASTURTIUM
Where ever I had them planted last year, no slug problems. It was a bad year for slugs with more than a foot of rain that fell over 1 month last summer. We where collecting slugs in very low bowls full of beer every day. Now I know why the 2 beds that had nasturtium in them had no slugs or aphids for that matter

ROSEMARY
kept those mosquitos down around the back stairs, and the slugs out back too

SAGE
That explains why my neighbors front yard had no ticks, and the dog didn't get ticks when in the front yard but did in the back yard.
She has at least 50 plants of just common sage planted around the front yard

Fran

Pennyroyal is good for keeping mosquitoes away too. And fleas. Many organic flea sprays have pennyroyal extract in them. Just be careful if you are pregnant. It was also used as a means of aborting an unwanted fetus in older days.

Fran , I also read that 4o'clocks are poisonous to JB's. That is why I did a seed trade for them. I had a lot of JB's last year and I could not keep up with them.

I hope I WS the 4O'Clocks properly cause I plan to plant them everywhere!

Karen

Karen, four oclocks need lots of heat to germinate. And the seeds rot quickly. I treat them like a tender annual. They were the first thing to get hit by the frost in the fall. If they sprout, you may need to bring them in from time to time.

I think I sow my 4:00s with the Zinnias in April...never had a problem with them germinating, but couldn't tell you WHEN they sprouted.

thanks mmqchdygg! April gives me some time to get more containers!

Karen
