Planting Mums Near Roads: Salt Tolerance and Distance

Can Chrysanthemums Survive Road Salt?

Road salt runoff can damage many plants, but mums are moderately tolerant if planted far enough from the spray zone.

Key Factors

• Distance: Plant at least 10–15 feet from pavement.
• Drainage: Avoid low spots where salty meltwater pools.
• Soil prep: Amend with compost and gypsum to help leach salts.

Recovery

Established plants often bounce back once spring rains flush salts deeper. Grass is the safest choice right against the road; use mums further back in the bed.

Ask Yourself

How close is the planting spot to the guardrail? Is there a ditch or swale? The further from direct runoff, the better.
