Are Coffee Grinds Good for Hydrangeas

Coffee grinds are not typically considered to be good for hydrangeas. This is because coffee grinds can alter the soil pH, which can then affect the uptake of nutrients by the plant. Additionally, coffee grinds can attract animals that may dig up and eat the roots of the hydrangea.

If you love spending time in your garden, you may be wondering if coffee grinds are good for hydrangeas. While there is some debate on the subject, many gardeners swear by using coffee grinds as a natural way to boost the growth of their hydrangeas. Coffee grounds are rich in nitrogen, which is an essential nutrient for plants.

When used as a mulch or added to compost, coffee grounds can help improve the drainage and aeration of soil while also providing a slow-release source of nutrients. This can be especially beneficial for hydrangeas, which prefer slightly acidic soil conditions. In addition to being a great source of nutrients, coffee grounds can also help deter pests and diseases.

The strong smell of coffee can help mask the scent of your hydrangeas, making it harder for pests to find them. And since Coffee is naturally high in caffeine, it can also act as a natural fungicide and insecticide. Simply sprinkle used coffee grounds around the base of your plants to keep pests away.

So if you’re looking for a natural way to give your hydrangeas a boost, consider adding coffee grinds to your gardening routine!

How Do I Put Coffee Grounds on My Hydrangea?

It’s easy to use coffee grounds to fertilize your hydrangea. Just sprinkle the grounds around the base of the plant and water it in. The coffee grounds will release nutrients into the soil that will help nourish your plant.

What Color Do Coffee Grounds Turn Hydrangeas?

While the color of coffee grounds may vary depending on the type of coffee bean used, they will typically turn hydrangeas a deep pink or purple hue. To achieve this color change, simply mix used coffee grounds with water and apply it to the soil around your hydrangea plants. For best results, do this every few weeks throughout the growing season.

Which Plants Do Not Like Coffee Grounds?

Coffee grounds are a popular addition to many gardens, as they provide a rich source of nutrients and can help improve drainage. However, not all plants appreciate the presence of coffee grounds in their soil. Here are some examples of plants that do not like coffee grounds:

1. Azaleas: Azaleas are acid-loving plants, so they prefer soils with a lower pH. Coffee grounds can raise the pH of soils, making it less acidic and more alkaline. This can cause problems for azaleas, as they may struggle to uptake essential nutrients from the soil. 2. Gardenias: Like azaleas, gardenias prefer acidic soils with a lower pH. Adding coffee grounds to their soil can make it more alkaline, which can lead to yellowing leaves and stunted growth.

3. Begonias: Begonias thrive in moist soils with good drainage. However, coffee grounds can make soils too dense and compacted, causing problems with water retention and leading to root rot. It’s best to avoid adding coffee grounds to begonia beds altogether.

4. Fuchsias: Fuchsias need well-drained soils that are slightly acidic in order to flourish. The addition of coffee grounds can make soils too heavy and dense, preventing proper drainage and potentially causing root rot or other issues.

Do Coffee Grounds Turn Hydrangeas Pink?

If you love spending time in your garden, you may be wondering if there’s a way to use coffee grounds to make your plants more vibrant. You may have heard that coffee grounds can be used as fertilizer, or even that they can change the color of hydrangeas. So, do coffee grounds turn hydrangeas pink?

As it turns out, coffee grounds can indeed be used to change the color of hydrangeas. This is because coffee grounds contain high levels of nitrogen, which is a key nutrient for plants. When applied to the soil around hydrangeas, coffee grounds can acidify the soil and encourage the uptake of nitrogen by the plant roots.

This increased level of nitrogen will cause the hydrangea flowers to turn pink. Of course, you’ll need to experiment a bit to get the perfect shade of pink for your liking. And, it’s important to note that too much nitrogen can actually result in stunted growth or yellow leaves on your plants.

So, be sure to use coffee grounds sparingly and always monitor your plants closely when using them as fertilizer.

How Often Should You Add Coffee Grounds to Plants?

Adding coffee grounds to plants is a great way to give them a boost of nutrients. However, you don’t want to overdo it, as too much can actually be harmful. A good rule of thumb is to add about 1 cup of coffee grounds per week for each plant.

If you have a large number of plants, you may need to increase this amount.


If you’re looking for a way to perk up your hydrangeas, coffee grinds might be the answer. According to gardening experts, coffee grinds can provide a number of benefits for hydrangeas, including improved drainage, increased acidity, and enhanced nutrients. So if you have a few extra coffee grinds lying around, don’t throw them out – your hydrangeas will thank you for it.
