Introduction

After a loved one passes away, the inevitable question arises: what should be done with their remains? While traditional burials or scattering of the ashes at a special location are common options, cremation has become increasingly popular in recent years. But what happens to the ashes after the cremation? Surprisingly, cremated ashes can be used to benefit plants and their growth.

Ashes as a Fertilizer

Ashes from the cremation process are comprised of mostly calcium, phosphorus, and potassium, also known as macronutrients. These macronutrients are essential for plant growth and development. In fact, the use of ash as a fertilizer dates back to ancient Rome where it was used to enhance crop yield. In modern times, ashes have been used to benefit plants in a variety of ways, including:

Improving soil pH balance:

Ash can help balance the pH level of soil, making it more alkaline if it is too acidic. This is particularly beneficial for plants that prefer a high pH level such as lilacs and clematis.

Providing nutrients:

Ashes are an excellent source of calcium, potassium, and phosphorus, which are critical for plant growth. By adding ash to the soil, plants can absorb these nutrients, leading to healthier and faster growth.

Preventing fungal diseases:

Ashes can also help prevent fungal diseases in plants such as powdery mildew and rust. This is because ashes lower the pH level on the plant's surface and prevent the growth of fungi.

How to Use Ashes as Fertilizer

Using ashes as a fertilizer is relatively simple. The ashes can be transferred to the soil in one of two ways:

Direct application:

The ashes can be applied directly to the soil in the desired location. A general rule of thumb is to apply one pound of ash per 100 square feet of soil. However, the amount should vary according to plant species and soil type.

Composting:

The ashes can be mixed into compost which will then be applied to the soil. Composting ash will help balance the pH for planting and protect the earth from over-acidification, resulting in improved soil nutrition, soil structure, and water retention capacity.

Conclusion

As surprising as it may seem, cremated ashes can be an excellent source of nutrients for plants. Whether added directly to soil or compost, ashes can help balance pH levels, provide essential macronutrients, and prevent fungal diseases. Using ashes in this way not only benefits plant growth, but also serves as a way to honor the memories of those who have passed away.
