This time of year, it’s not unusual to hear people with gardens talk about buying milkweed plants or seeds so that they, too, can be a haven for monarchs. And they do, in fact, need havens. If you’re interested in attracting butterflies and other pollinators, you’ll want to know the best approach—like using only native milkweed to feed Monarch caterpillars and butterflies and planting a variety of natives so that flowering occurs throughout the year to support other butterflies, bees, and other insects. I got some great sources to help us learn how to go about it for my new story for The San Diego Union-Tribune’s Home & Garden section.
