Fire pits are a great way to remove woody material and hedges from your yard or garden. The resulting ash is an excellent homemade fertilizer for many plants because it contains potassium, phosphorus, calcium, and other minerals that are needed in certain amounts for healthy plants. However, there are many people who want to know the benefits of ashes for the rose bushes that they have in the garden.
Therefore, in this article we are going to tell you everything you need to know about the different benefits of ashes for rose bushes.

Due to its calcium content, wood ash has a very alkaline pH, while roses thrive in slightly acidic soils with a pH between 6 and 7 and an optimal soil acidity of 6,5. Therefore, do not immediately add large amounts of wood ash to the surrounding soil of established rose bushes.
However, roses do benefit from an occasional sprinkling of wood ash during the growing season before they bloom. Wood ash contains high amounts of potassium, an essential nutrient that roses need to flourish and produce high-quality flowers.
It is important to understand soil pH and how to apply wood ash correctly to minimize the effects of alkalinity while using potassium and other nutrients and minerals.
If the soil you want to grow new roses in has an acidity below 6, adding a half pound of wood ash to the soil surface and watering it in will restore the soil to optimal levels. When planting new roses, it is always good practice to test the soil with a soil test kit to measure the pH of the soil before planting. Even within a small area, the pH of the soil in your garden can vary widely. If the soil is particularly acidic (pH 5 or lower), the roots of the rose will be affected and the rose may die.
However, this is easy to fix. You can improve the soil by adding wood ash (one cup at a time) and retesting the soil after four weeks. It is recommended to dig the wood ash into the ground with a fork or a spinner to change the soil profile.
Use only one cup of ash at a time in acidic soils. Too much ash at one time will cause the soil to have an alkaline pH, and then you will need to add paraffin fertilizer to rebalance the effects of the ash.
Wood ash also has the advantage of being free of seeds and roots that could become weeds. The intense heat of the fire renders all seeds, roots, and rhizomes of annual and perennial weeds inert. While other compost or mulch from yard or kitchen waste can hold seeds and roots for a long time, which will sprout and grow once the compost has been spread throughout the garden. This means that you may have to spend more time weeding than necessary.
Also, most compost piles don't contain anywhere near the level of wood ash potassium, so this is a great way to use compost as an ash mulch and greatly increase the potassium levels your roses need to grow. bloom during the growing season.
when it applies
If the roses contain composted wood ash, the best time to use the wood ash is during the growing season, which It is early spring in April and May. The potassium content in wood ash promotes flower growth, so your roses will bloom at their best for as long as possible.
Application in early spring or earlier allows the water-soluble potassium to reach the rose roots at the right time to stimulate flowering. Like all fertilizers, adding wood ash compost in late summer (after August 15) is not recommended, as this can encourage new rose growth later in the season as winter approaches. The new growth is obviously more vulnerable to cold weather damage, and the fragile new growth will die once the first frost arrives.
If you have excess ash, it is recommended that you keep it dry for the next season or spread it elsewhere in the garden, as other plants will appreciate the potassium content. Lawns in particular can benefit from adding wood ash.
How to apply ashes to rose bushes
There are only two application methods that are recommended when fertilizing rose bushes:
- In early spring, before it blooms, you can sprinkle a small amount of wood ash around the base of the rose, but be aware of alkalinity. Aim for about a half cup of ash per rose bush. There is no need to rake or dig, as this will disturb the roots of the rose and unnecessarily disrupt the ecology of the soil. The main nutrient in wood ash that benefits roses (potassium) is water soluble, so flushing the ash with about two gallons of water should help get the potassium to the roots quickly. This is why it is important to apply wood ash to roses before or during flowering.
- Second, I think the best option is to add wood ash to your compost pile early in the year and spread the compost around the rose bushes as mulch.
It depends on keeping the compost pile indoors or at least avoiding too much rain as this can wash away useful potash from the compost pile as it is a water soluble mineral. As the bottom layer of cardboard rots, it adds valuable carbon to the pile, helping to balance nitrogen levels for more fertile compost.
But mainly cardboard is used after adding wood ash to keep the water balance and keep the potassium concentration to be able to fertilize the rose bushes. Mixing the ash with compost also provides potash and other minerals that roses love without changing the pH of the rose bed.
Compost consisting of grass clippings, leaves, and kitchen scraps will break down into a neutral or slightly acidic pH mulch. This is helpful because it has the best pH for roses and counteracts the alkalizing effects of wood ash.
It's worth reiterating that wood ash contains potassium, phosphorous and calcium, all of which are beneficial for rose growth, and minerals that are difficult to obtain from standard compost in organic gardening.
The benefit of adding rose ash to a compost pile and then spreading it around the base of the roses is that compost made from leaf mold, grass clippings and kitchen scraps help improve soil structure. Roses love organic material because it absorbs water and drains well. This allows the roots of the roses to absorb water when they need it without overloading the soil. This makes the plant more resistant in dry climates.
I hope that with this information you can learn more about the benefits of ashes for rose bushes.
