Have you ever wondered if the coffee grounds you toss in your garden could be bothering some plants? You might be curious about the types of plants that actually dislike those rich, dark coffee remnants. The truth might surprise you! Stick around as we explore which plants don’t appreciate coffee grounds and why.
What Are Coffee Grounds?
Before diving into the list, let’s clarify what coffee grounds actually are. Coffee grounds are the leftover bits that remain after brewing coffee. They are often considered a great fertilizer because they are rich in nutrients. However, not every plant enjoys these nutrient-rich scraps.

Coffee grounds are acidic. While many plants thrive in acidity, others prefer a neutral or even alkaline soil. If you're curious about how caffeine affects your body, you may also want to check out this article on How Caffeine Affects Your Body for more insights on the properties of coffee!
1. Plants That Prefer Alkaline Soil
Some plants thrive in alkaline conditions, which means they require less acidity than what coffee grounds provide. Here are a few examples:
Tomatoes
Many gardeners adore growing tomatoes. However, they thrive best in neutral pH levels, around 6.0 to 6.8. If you add too many coffee grounds, it can increase acidity and stunt their growth.
