- Diamond Crystal Bright & Soft Salt Pellets, 40 lb. Bag
- 5 gal plastic Home Depot bucket (fill bottom of bucket 1/4 - 1/3 salt, then add water until bucket is half full).
After a day or two (and some occasional stirring), the salt pellets will have begun to breakdown and the water molecules will have become completely saturated with sodium to a maximum salinity of 26.3%. Add a squirt of Dawn dish washing liquid and stir. Put in HDX sprayer. Spray blackberry and watch it die.
