Potassium is a mineral and electrolyte that plays a vital role in keeping bones and muscles strong, supporting heart health, supporting lower blood pressure, and reducing the risk of kidney stones. It's also essential for the brain and nervous system, and a deficiency in potassium can cause muscle cramps, low energy levels, irregular heartbeat, and stomach issues.
In the body, potassium is found in foods such as spinach, avocados, bananas, carrots, celery, tomatoes, raspberries, cherries, and nuts. However, many people don't get enough potassium through their diet.
For example, most Americans consume a diet that contains more sodium than potassium, which increases the risks of high blood pressure and heart disease. If you're trying to improve your potassium intake, consider increasing the amount of fruits and vegetables you eat.
You can also take a supplement with potassium. A capsule with 250 mg of potassium will provide 10% of your daily recommended value.
If you want to prevent and control powdery mildew on your grape vines, you can use a foliar spray of potassium bicarbonate. Apply the solution within seven days of the first signs of mildew and repeat applications every 7 to 14 days thereafter to help keep your grapes healthy.
You can buy potassium bicarbonate at your local pharmacy, garden center, or hardware store. It's usually sold in 2-ounce bottles, so you can make a large amount of spray with just one bottle.
