Cover your plants with a frost blanket to create a physical barrier between the treated area and the plants.
Put on a pair of gloves to avoid drying out your hands.
Broadcast magnesium chloride salt over the icy area at a rate of roughly 1/4 cup magnesium chloride salt per square yard. Avoid spreading the salt onto grass or plants.
Wait for the ice to melt, which should take approximately 20 to 30 minutes.
Scoop the melted ice up with a shovel and dump it in the trash can or an area far from any growing plants. Removing the magnesium chloride from the area will protect your plants from the negative effects of any runoff salt.
Uncover the plants once the deicing salt has been removed from the area, if you wish.
