A gardener has shared a simple hack that can help turn hydrangeas blue, and all you need is the grounds from your morning coffee.
The scoop
Coffee grounds lower the pH of soil, making it more acidic, which can result in blue hydrangeas, according to a post by gardener and TikToker LauraBloomsFlowers (@laurabloomsflower).
@laurabloomsflower Good morning ☕️ Did you know that coffee grounds can help hydrangeas by increasing the soils acidity, which can help with blue blooms?🩵 Although, mine are more lilac, they are still beautiful! #gardentok #hydrangeas #bluehydrangea #coffeegrounds #coffee #gardening #flower ♬ 오리지널 사운드 – 나만듣GO – 김쇼츠 music
All you need to do is pour the coffee grounds at the base of the plant. While it won’t ensure blue blooms, the flowers look pretty nonetheless, as Laura’s lilac hydrangeas show.
How it’s helping
As well as helping turn hydrangea blooms blue, coffee grounds are a natural alternative to store-bought fertilizer. Coffee grounds help to enrich soil with nutrients such as nitrogen, phosphorus, and potassium while also improving structure and water retention, per the Texas A&M Agrilife Extension.
Many natural alternatives to synthetic fertilizers can boost your soil and save you a considerable amount of money. Natural alternatives such as compost, animal manure, and even seaweed release nutrients slowly and are much better for the environment than synthetic fertilizers bought at the store.
Synthetic fertilizers often leach chemicals into the environment, polluting natural ecosystems such as rivers, lakes, and ponds and resulting in algal blooms, which decrease the amount of oxygen available for aquatic plants and animals. A decrease in oxygen can result in fish die-offs or dead zones where nothing can grow.
