Frequently Asked Questions
How much land do I need to start a butterfly garden?
Every plant that you can grow can make a difference for visitors to your garden, especially in urban areas. Potted plants are also useful en masse for pollinators. When planting your garden, make sure you plant both the host plants and nectar plants for the adults to feed on.
Where should I get my plants?
For pollinators, it is best to have native plant species. The insects will be used to these plants more than ones from other places. Be sure you get your plants from a reputable nursery that does not use neocontinids that would harm visitors to your garden.
