Weed Control – Effectiveness of Salt
Q: What is your opinion about using salt for weed control under my birdfeeder?
A: As a rule, I don’t recommend using salt for weed control. The sodium part of the salt molecule makes clay soil harder plus it dissolves in rain and burns nearby plant roots. However, if you don’t have plants nearby I guess your idea would work. The only other drawback could be if deer discover your ready-made salt lick.
