- If you run over the foliage with your lawn mower you’ll definitely smell it…but so will the aphids!

- Overly dry soil can cause leaves to brown prematurely.

Summer Beauty Growing Tips:
- Grow by milkweed to repel aphids.
- Fall division suggested: gives roots time to acclimate before winter and you know where everything is growing.
- Don’t Cut- the flower heads after they dry up. They hold shape for visual interest over winter and this sterile cultivar doesn’t reseed.
- Extend bloom time by adding late flowering all-white Allium tuberosum (garlic chives). A. tuberosum is another popular pollinator flower that you can eat too. Monarchs are tuberosum pollinators.
This allium variety is popular with bumble bees, red admirals, honey bees, tiger swallowtails, and more.
