Coffee Grounds in the Garden: A Blessing and a Warning

Discover the wonders of coffee grounds as a plant-loving elixir, boosting growth and health for your garden, while also learning about the 7 species to avoid!

There is no doubt about how effective coffee grounds can be whenever you bring them close to your garden. They enrich the soil with vital nutrients like nitrogen, potassium, and phosphorus. However, not all plants appreciate this “magical ingredient” as some species like geranium, asparagus or certain herbs may suffer adverse effects from coffee’s acidity. Let’s talk about this in-depth and see what coffee grounds are all about.

I- Coffee Grounds: More Than Just Drain Cleaner:

You’ve probably heard of used coffee’s cleaning and descaling powers, and it’s even hailed as a natural beauty ingredient. But did you know it can also work wonders for your garden?

It is quite versatile indeed and can do more than just one marvelous job. In your garden, it turns into a nutrient powerhouse, boasting a wealth of essential minerals like potassium, nitrogen, and magnesium. You can boost your compost by incorporating used coffee into the soil or generously sprinkling it around the base of your plants.

II- Green Goodness for Growing:

This all-natural wonder works wonders for a variety of plants, as showcased by these examples:

– Camellia: Adores acidic, nitrogen-rich soil, making used coffee the perfect match.

– Roses: A little coffee ground mix in the soil stimulates abundant flowering.

– Strawberries: For sweet and juicy berries, nourish the soil with coffee grounds.

– Palms: With their mineral-rich goodness, coffee grounds promote robust palm growth.

– Carrots: This element boosts carrot growth, making them faster and healthier.

– Alocasia: A potassium lover, Alocasia thrives with this budget-friendly nutrient source.

Do you know what the best part is? The fact is that this list is endless. Many plants other than the ones we mentioned benefit from used coffee. Embrace the green goodness and watch your garden flourish with this incredible ingredient that you once thought about tossing in the trash can.

III-Handle with Care: Sensitive Plants and Used Coffee:

We won’t doubt the fact that coffee grounds can work miracles around certain plants, but sadly not around all of them, as some are a bit touchy about this caffeinated treat:

– Salads: It slightly hinders growth but helps keep slugs at bay.

– Potatoes: Not a fan of used coffee or any Solanaceae vegetables, as they can stunt growth or even kill them.

– Cactus: With its distaste for nitrogenous soils, it’s not surprising that cactus shies away.

– Eggplant: Similar to potatoes and salads, used coffee can hinder growth.

– Petunia: Growth and flowering are inhibited by coffee grounds.

– Young Shoots: Best for shoots over 6 months old.

We can agree that used coffee is not perfect for all, but still, its unfavorable effects are quite rare compared to the many plants that adore it.
