Planting and Maintaining a Garden

Monarch Joint Venture provides great information about gardening for monarchs. Their Schoolyard Gardens flyer is especially helpful for those developing a butterfly garden with students or a youth group, and the Gardening for Monarchs has great information about planting and maintaining a garden for monarchs and other butterflies and pollinators. Here is a brief summary of the document: 

  1. Choose a sunny location.
  2. Include windbreaks, such as a fence, shrub, or wall.
  3. Test your soil to make sure it is adequate for planting.
  4. Prepare soil by removing lawn or other plant cover and raking.
  5. If space is limited, consider planting in pots or containers.
  6. Milkweed is a necessity for monarchs, so plant milkweed! 
  7. Include a variety of different blooming species so that nectar is available throughout the growing season.
  8. Use native plants whenever possible.
  9. Water plants initially, until they are well established. You may also want to water in drought conditions. 
  10. Avoid using herbicides or insecticides to get rid of unwanted plants or insects. Weed by hand as needed.
