>>1486655For ladybugs specifically it is a bit difficult since they are home on just about anything with aphids and such to eat. Having an insect hotel for them to overwinter in will help a great deal. Flower that produce lots of pollen can help. I've read that the following are good herbs and flowers for them: fennel, cilantro, dill, yarrow, caraway, tansy, coreopsis, angelica, cosmos, & scented geraniums.
