Identification and management tips
- Hoary cress has white flowers and blue green leaves which clasp the stem.
- For small infestations, digging within 10 days after plant emergence for 2-4 years can be effective.
- Long-term reductions must include planting with competitive grasses to occupy ground once infested by the weed.
