1 Flush the soil thoroughly with distilled or rainwater to leach out accumulated mineral salts and prevent further tip burn.

2 Switch to using filtered or rainwater for future waterings and avoid over-fertilizing to prevent new salt buildup.

3 Monitor soil moisture levels closely using a moisture meter to ensure you are not overwatering, which can exacerbate salt concentration.
