Do Roses Like Coffee Grounds and Eggshells

Do Roses Like Coffee Grounds and Eggshells?

The short answer is yes, roses can benefit from coffee grounds and eggshells when used correctly. Coffee grounds are packed with nitrogen and other essential minerals, while eggshells provide a boost of calcium.

These nutrients, combined with the improved soil drainage and ecosystem that coffee grounds create, can lead to healthier and more vibrant roses. However, it’s important to note that moderation is key, as too much of a good thing can sometimes be harmful.

How Coffee Grounds Benefit Roses

Nitrogen and Other Essential Minerals

Roses, like all plants, need essential nutrients to thrive. Nitrogen, phosphorus, potassium, and copper are particularly important for roses as they help with growth and overall health.

Luckily, coffee grounds are a natural source of these nutrients, making them an ideal fertilizer for our rose gardens. When used in moderation, coffee grounds can provide a much-needed nutrient boost for our beloved blooms.

Improving Soil Drainage and Feeding the Soil’s Ecosystem

Healthy soil is the foundation of a thriving rose garden, and coffee grounds can play a significant role in improving soil quality.

By adding organic material like coffee grounds to the soil, we can enhance its structure and feed the microscopic critters (like earthworms and microbes) that break down organic material into a form that our roses can absorb.

Did you know that worms are a rose gardener’s best friend? These little wrigglers are excellent at aerating compact soil, which in turn improves soil drainage. Plus, they love to munch on coffee grounds, so adding some to your garden is like throwing a worm party – and we all know how fun those can be!

Coffee Grounds for Roses

If you’re looking for an organic way to fertilize your roses, coffee grounds might be the answer you’re looking for. Coffee grounds are packed with nitrogen and other essential minerals that can benefit your roses when used correctly.

They can also help to reduce soil contaminants and improve soil structure. Simply sprinkle fresh or used coffee grounds around the base of your roses and watch them thrive.

The Role of Eggshells in Rose Gardening

Though coffee grounds steal the spotlight, let’s not forget about the humble eggshell. Crushed eggshells are a fantastic source of calcium for our roses, helping to strengthen cell walls and prevent issues like blossom end rot. Plus, they can act as a natural pest deterrent – bonus points for that!

When and How to Apply Coffee Grounds and Eggshells

When to Apply Coffee Grounds

Timing is everything, especially when it comes to fertilizing our rose gardens. Applying coffee grounds too early or late in the season can stimulate new growth that is susceptible to frost damage.

So, when’s the best time to apply coffee grounds? Aim for spring, specifically around April or May, when your roses are waking up from their winter slumber. Avoid application after August 15th, as new growth needs time to harden and prepare for winter frosts.

How to Apply Coffee Grounds as a Fertilizer for Roses

There are a few ways to help your roses reap the benefits of coffee grounds without causing harm:

  • Distribute half a pound of coffee grounds around each mature rose plant and water in with 2 gallons of water (a whole watering can). This method ensures that the nitrogen content doesn’t overwhelm your roses’ delicate root systems.
  • Mix half a pound of coffee grounds with 2 gallons of water and apply it as a liquid fertilizer. This method allows for a more even distribution of nutrients and is gentle on your roses’ roots.
  • Add coffee grounds to your compost pile. This is an excellent way to incorporate the nutrients into your garden indirectly, as the compost will break down the coffee grounds over time, releasing their goodness into your soil.

Using Eggshells in Rose Gardening

To make the most of eggshells in your rose garden, follow these simple steps:

  • Crush the eggshells into small pieces – the smaller, the better, as this increases the surface area for calcium release.
  • Sprinkle the crushed eggshells around the base of your rose plants. This will provide a slow-release calcium boost while deterring pests like slugs and snails that might want to munch on your roses.

Frequently Asked Questions (FAQs)

Here are some common questions and concerns about using coffee grounds and eggshells for roses:

Are there any risks associated with using coffee grounds and eggshells in my rose garden?

As long as you use moderation and follow the application guidelines outlined in this post, coffee grounds and eggshells should not pose any risks to your roses. Overapplication can lead to nitrogen burn or imbalances in soil nutrients, so stick to the recommended amounts.

How often should I apply coffee grounds and eggshells to my rose garden?

Apply coffee grounds once or twice per year, ideally in spring (April/May) and again in early summer if needed. Eggshells can be applied once a year in spring or early summer.

Where can I get coffee grounds if I don’t drink coffee?

Many coffee shops and cafes are happy to give away used coffee grounds to gardeners for free. Just ask your local barista, and they’ll probably be more than happy to help you out!


Using coffee grounds and eggshells in your rose garden can have a multitude of benefits, from providing essential nutrients to improving soil structure and deterring pests. The key to success is proper application methods and timing. So, give these natural fertilizers a try and see how they can transform your rose garden while reducing waste.

Happy gardening, my fellow rose warriors! Let’s continue nurturing our blooms and creating beautiful spaces that bring joy to ourselves and those around us. Don’t forget – moderation, timing, and a little love can go a long way in making our roses thrive!
