Brandon,
I think the marigolds and summer savory are a bit late to seed; however, maybe you can buy plants at a nursery. I think you can just hand pick a small garden. Or knock them off the plant in to a
bucket of soapy
water.
With any luck, the plants will also outgrow whatever is damaging the plant. Look at the growing point of the plant and watch for new growth. I'm sorry I can't be more help on this, but I'd like to hear how it goes.
Perhaps someone else will have more to offer.
Justin
