By adding coffee grounds to your roses, you create a barrier that will keep pests away and allow your rose bushes to thrive. So if you're wondering whether coffee grounds are good for roses, the answer is a resounding yes! Coffee grounds are an inexpensive and readily available organic fertilizer for your roses.
You can either add the coffee grounds directly to the soil around your roses, or you can compost the coffee grounds first.
Leftover coffee grounds can be very beneficial to roses when used in moderation. They feed the plants with readily available nutrients (nitrogen, phosphorus and potassium, etc.), lower soil pH, attract worms and improve soil structure.
Excessive acidic soil can kill or hamper the growth of plants like asparagus fern, Chinese mustard, Italian ryegrass, lavender, orchids, rosemary, tomatoes, and geranium. The roots of these plants are also not potent to absorb the nutrients added by the coffee grounds in the soil.
Coffee grounds contain compounds that feed healthy soil but they don't lower pH. Eggshells do not prevent blossom end rot. They add organic material for soil organisms, but you may as well just put them in the compost. Epsom salts can be harmful to soil, plants and water.
Helps With Nutrient Intake
"When rose plants have sufficient magnesium levels, they can more effectively utilize these nutrients, promoting overall growth and development." Additionally, Epsom salts' sulfur content also helps with nutrient uptake.
Distribute half a pound of coffee grounds around each mature rose plant and water in with 2 gallons of water (a whole watering can).
Don't just pour it down the drain — you can use it to fertilize your plants, both indoor and outdoor. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health.
Since coffee grounds have such a pungent and intense smell, mosquitoes do not like to come near it. Mosquitoes are repulsed by all types of coffee, whether it is fresh, used, or burnt. The most effective way to use coffee grounds for mosquito control is by burning them, as it creates a stronger aroma.
How Often Should You Add Coffee Grounds to Plants? You can fertilize houseplants an average of 7 to 10 days in a row, but no more, as there is a risk of over-acidification of the soil. A cup of ground coffee should be added to the compost once a week.
There's a great way to feed your roses coffee grounds, which lowers the ph on soil and attracts worms which loosen and feed the soil- great for roses! It's simple, just collect your coffee grounds and -per bush- use 1 cup of grounds to 1 gallon of water. Mix, and water the roses with it.
FOR ESTABLISHED ROSES:
Early to mid-spring: Begin fertilizing when new leaves emerge. Use a high-nitrogen fertilizer or top dress with alfalfa meal (5-1-2) for the first application to jump-start leaf development, along with epsom salts to encourage new cane development and lusher growth.
Newly planted roses – water every two or three days. Established roses – water once or twice a week as needed to keep the soil moist around your roses.
Fertilize and water on schedule.
"As roses are establishing, maintain an adequate water supply to keep them thriving," she says, adding that the use of a blossom boosting water-soluble fertilizer during the growing season can be helpful to spur new blooms, as well.
Coffee grounds are rich in nutrients, especially nitrogen. They also have some amount of other nutrients like potassium and phosphorous. Overall, this means that adding coffee grounds to your garden can work fairly well as a fertiliser. Coffee should be spread in a thin layer, rather than being clumped in one place.
"The three main nutrients roses need from fertilizer are nitrogen, phosphorus, and potassium," says Kristen Smith, plants coordinator and rose product manager at Star® Roses and Plants. She also notes that roses require a range of micronutrients, including iron, calcium, and magnesium.
Not only do they repel mosquitoes, but also other insects such as wasps and bees. Coffee grounds are the bee's knees when it comes to staying bug bite free. Most bugs have a very strong sense of smell. Coffee grounds are very potent and even more potent once they are burned.
“the smell of the coffee repels snails, slugs and ants. You may also have success using coffee grounds to repel mammals, including cats, rabbits and deer.”
Coffee beans, grounds and brewed coffee contain caffeine, a very dangerous and toxic chemical to cats and dogs. Ingestion can be life threatening. According to the Pet Poison Helpline, a moderate amount of coffee can easily cause death in small dogs or cats.
Coffee contains a lot of nitrogen, which not only kills off weeds and bacteria but can also help certain types of plants (a.k.a those that prefer more acidic soil) flourish. Plus, your daily cuppa also contains significant amounts of magnesium and potassium, both of which are key factors in plant growth and health.
Eggshell Benefits
As it happens, eggshells can provide all the calcium carbonate the soil needs, which helps to lower the soil's pH level and make it more alkaline as opposed to acidic. This is incredibly beneficial for plant growth because many plants prefer to grow in soil that has low acidity.
Some gardeners report success in turning their hydrangeas blue by applying coffee grounds to the soil. The coffee grounds make the soil more acidic, allowing the hydrangea to more easily absorb aluminum. In addition, fruit peels, lawn clippings, peat moss and pine needles, are thought to have a similar effect.
So, when it comes to coffee grounds and roses, the key is to use them in moderation. A little bit will give your roses a boost, but too much will do more harm than good.
We recommend a good feed of a nitrogen high feed like “Top Rose Gold” after the late-winter prune in February, then feeding every two weeks throughout the flowering period with a high potash feed like “Tomorite” or "Uncle Tom's Rose Tonic".
These things are great for nutrient poor lawns and lawns on clay or sandy soil. However, coffee grounds still contain some residual caffeine, which can cause harm to the micro fauna in your soil, and that's why it is not recommended to apply coffee waste directly to your lawn.
