Fight Fungus with Baking Soda

Turn Pink Hydrangeas Blue with Vinegar

Unlike baking soda, distilled white vinegar is acidic, and acidic soil is the secret to turning your pink hydrangeas blue. (Note: This doesn’t work on white hydrangeas.) Vinegar also enhances the soil of acid-loving plants like azaleas, rhododendrons and gardenias. Use a cup of white distilled vinegar to a gallon of tap water. Do you know the difference between apple cider vinegar and white vinegar?

Say Goodbye to Beetles with Dish Soap

My biggest complaint with Japanese beetles is how they can quickly turn beautiful zinnia leaves into lacy remnants of their former selves. They also decimate over 300 other types of garden plants. Unfortunately, the best way to get rid of them is to hand-pick them off your plants…and drown them in a mixture of water and dishwashing soap. Sorry…not sorry….we’re talking zinnias here!  For your own safety, these are the safest dish soaps you can buy.

Attract Earthworms with Coffee Grounds

Adding coffee grounds to your soil benefits your soil by attracting earthworms and microorganisms (both of which make your soil healthier and more fertile). But note: fresh coffee grounds are acidic, whereas used coffee grounds are neutral. If you are enhancing the soil of an alkaline-soil loving plant (such as geraniums or sweet tomatoes), then used coffee grounds are the way to go. Find more ways to repurpose coffee grounds.
