Milkweed Seed Bombs

Description

Help to save monarch butterflies and pollinators by planting native milkweed. Milkweed leaves are the sole food source for monarch caterpillars, while its flowers feed several species of endangered wild pollinators with their abundant nectar.

Plant milkweed easily

In order to be planted in the spring, milkweed, like most native northern plants, must undergo a cold treatment of at least 30 days under certain conditions (temperature, moisture, etc.). Good news, we've already done that for you!

Our milkweed seed bombs are already cold stratified and wrapped in enriched potting soil, clay and compost.

This treatment mimics the winter conditions that seeds are exposed to and helps deactivate the chemical and physical barriers that prevent sprouting. These protections are a natural adaptation of milkweed seeds and other northern plants, which prevents them from germinating prematurely during a fall or winter thaw followed by a frost. Without cold stratification, germination rates can be very low (3-4%). The clay and potting soil envelope of our seed bombs will allow the seeds to germinate without being eaten by birds or rodents.
