Dandelion: How to Identify and Control It
Taraxacum officinale · Perennial broadleaf
How to identify dandelion
- Rosette of deeply toothed leaves
- Bright yellow flowers on hollow stems with milky sap
- Puffball seed heads spread by wind
- Thick taproot that can regrow from fragments
Why it shows up
Thin or under-fed lawns and bare spots. Wind-blown seed lands constantly, so dense turf is the best defense.
Control methods
1. Cultural (prevention)
- Maintain dense turf with proper fertilization and mowing height
- Fill bare spots promptly
2. Mechanical
- Dig with a weeding fork or taproot tool, removing as much root as possible
- Remove flowers before they go to seed
3. Organic options
- Repeated removal of top growth weakens plants over time
- Some horticultural vinegar and iron-based (FeHEDTA) selective products are sold for broadleaf weeds
4. Chemical options
Herbicide safety: The label is the law. Use only products labeled for your site and grass type, follow rate, timing, and weather directions exactly, wear listed protective equipment, keep people and pets off treated areas as directed, and check state and local rules. Active ingredients named here are examples, not endorsements.
- Selective broadleaf herbicides (e.g., 2,4-D, dicamba, mecoprop combinations) labeled for lawns
- Fall application is often most effective, as plants move sugars to roots
When to treat dandelion in the Mid-Atlantic
For perennials, fall is usually the most effective time for selective treatment — from mid-September until a few weeks after your first fall frost — because plants are moving sugars (and herbicide) down to roots. Spot-treat or dig in spring as needed.
