Milkweed is essential for monarch butterfly conservation, providing the crucial habitat and food source for their caterpillars. However, many gardeners face challenges with pests that can damage or kill milkweed plants. Fortunately, selecting pest-resistant milkweed varieties can lead to a healthier, more successful garden. Here are some top picks for pest-resistant milkweed that are easy to grow and maintain.
Why Choose Pest-Resistant Milkweed?
Pest-resistant milkweed varieties are bred or naturally possess traits that deter common pests such as aphids, milkweed bugs, and caterpillars that can become problematic. These varieties reduce the need for chemical interventions, making them an eco-friendly choice for gardeners aiming to support pollinators and butterflies.
