Why Coffee Grounds Can Help Roses
One of the main reasons flies use coffee grounds on roses is because they can improve soil health.
As Joe explains, you’ll often see more worms where coffee grounds have been used, which is a positive sign for the quality of the soil. ‘You’ll often see more worms too, which is always a good sign, and roses love that kind of healthy soil.’

‘Being able to recycle your coffee grounds to increase nitrogen for your roses is an easy, free way to help them without relying solely on chemical fertilizers,’ she says.
She adds that coffee grounds provide not only nitrogen but also trace amounts of potassium, phosphorus and micronutrients including calcium, copper and magnesium. Added to soil, they act as slow-release fertilizers, slowly releasing nutrients over time.
Richard Barker, Horticulturist LBS Horticulturealso highlights that they help feed beneficial soil microbes, improve overall soil health and make nutrients more available to plants.
Gardeners make the mistake of coffee grounds
The biggest misconception is that more coffee grounds equals a healthier rose.
In fact, adding too much can cause problems. Richard warns that coffee grounds sitting on the surface of the soil can clump together and form a water-resistant layer, making it difficult to penetrate the soil.
To avoid this, he recommends using coffee grounds sparingly and working them into the soil rather than leaving them on the surface.
If agree with this advice. ‘If you’re going to use it, I’ll go easy. A light sprinkle around the base and then is fine, or even better, pop them in the compost first so they’ve had a chance to break down properly.’

How to use coffee grounds on roses
Lucy recommends letting used coffee grounds dry completely before applying.
‘The best way to add used coffee grounds to the soil to help your roses is to first let them dry completely so you can sprinkle them over the soil rather than using them as a wet clump,’ she explains.
Once dry, he recommends applying up to two tablespoons per plant around the base of the rose, taking care to avoid the main stem.
After sprinkling the soil around the plant, gently work into the top 10 cm of soil with a hand rake and water well. This helps speed up decomposition, so nutrients are available more quickly.
Lucy also says you can make a liquid feed by soaking used coffee grounds in water overnight and using the resulting ‘coffee tea’ around the base of your roses.

Is it better to compost coffee grounds first?
According to experts I spoke with, composting coffee grounds is the safest option. Adding them to your compost pile breaks them down completely before you apply them to your borders, while also helping you build Utilization of kitchen waste which would otherwise be thrown away.
Once the compost is prepared, coffee grounds can be used around the roses as part of a nutrient-rich homemade compost.

What else should you feed roses?
While coffee grounds can add some growth, experts don’t recommend relying on them as your main rose fertilizer.
‘But if you want really good roses, coffee grounds are a small part of that,’ explains Joe. ‘A proper rose feed in the spring will always do more for growth and flowering.’
Richard recommends using a slow-release granular rose fertilizer, such as Miracle-Gro’s Rose & Shrub Continuous Release Plant Food, £8.49 at AmazonIn the spring before new growth begins. During the growing season, liquid seaweed feed, viz Envii’s SeaFeed Xtra, £13.95 at AmazonCan strengthen roots and improve plant resilience, while tomato feed can encourage strong flowering due to its potassium content.
Joe is also a fan of organic soil improvers. ‘Well rotted manure, like Westland’s Farmyard Fertilizer, which you can pick up from Amazon for £13.99But is a really good option because it feeds the plants slowly while improving the soil at the same time. Seaweed feed is another useful choice if you need something light during the growing season.
Lucy adds that Banana peel Can also be reused as a natural source of potassium for flowering plants such as roses.

So there you have it. Coffee grounds can certainly benefit roses, but they are not the miracle ingredient they are sometimes made out to be.
Used occasionally, they can improve soil health, support beneficial microbes and add organic matter to your borders, but are best used in conjunction with a proper rose feeding routine.
As Joe says: ‘ Once your soil is in good condition, roses are really easy to grow. Coffee grounds are a nice extra, but they’re definitely not the main thing.’
