Sunflower Ash (K*Ash)

Sunflower ash is a natural fertilizer that can be used to improve soil quality and promote plant growth. It is rich in nutrients such as potassium, phosphorus, calcium and magnesium, which are essential for plant growth.

*Improves soil structure.

*Stimulates microbial populations.

*Tempers soil acidity & improves plant immunity.

*Great source of phospherus, potassium & calcium.

*(P) 6%, (K) 36%, (Ca) 8%, 1 cup (1/2 lb) per 100 sf.


What is it?

K*Ash enriches the soil, tempers acidity, and improves soil structure and microbial flora while providing potassium and other essential nutrients. Its high pH (~10) is beneficial for flowers and perennials when mixed with compost and other organic materials. Not recommended in alkaline soils (pH 7 and above) or for plants that prefer acidic soils.

K*Ash (sunflower hull ash (0-4-34)) is potassium from a renewable source (not mined) with 4% phosphorus. Coarse Grind: screened to 20 mesh.


Enhanced Nutrient Availability: Sunflower Hull Ash is packed with essential nutrients like potassium, phosphorus, and micronutrients such as magnesium, calcium, and sulfur. These elements play a crucial role in promoting plant growth, increasing flower and fruit production, and maintaining overall plant health.

Improved Soil Structure: Adding Sunflower Hull Ash to soil amendments helps to improve soil structure by increasing the soil’s water-holding capacity and promoting better root development. This leads to healthier plants that are more resilient to environmental stress.

Reduced Soil Acidity: Sunflower Hull Ash acts as a natural soil conditioner, helping to balance the pH levels in acidic soils. By neutralizing excess acidity, it fosters a more hospitable environment for plant growth and nutrient uptake.

Environmentally Friendly: Using Sunflower Hull Ash as an ingredient in soil amendments and plant health products is an environmentally conscious choice. By recycling a byproduct that would otherwise be discarded, it promotes a circular economy and reduces waste.

Cost-Effective: Sunflower Hull Ash offers a cost-effective alternative to synthetic fertilizers and other soil amendments. Its affordable price point makes it an attractive option for gardeners and farmers alike.

How to use it?

1 cup (1/2 lb) per 100 sq ft

Transplanting: 1-2 tbsp per 6" planting site

1 tbsp per gallon of water; apply as a soil drench

Tips and Tricks

Here are some ways you can use sunflower ash in planting:

Mix it with compost - Sunflower ash can be mixed with compost to make a nutrient-rich soil amendment. Simply mix equal parts sunflower ash and compost and apply it to your garden beds. This will provide your plants with a slow-release source of nutrients.

Use it as a top dressing - Sunflower ash can also be used as a top dressing for plants. Sprinkle a thin layer of ash around the base of your plants and gently work it into the soil. This will help to improve soil structure and promote healthy root growth.

Make a liquid fertilizer - You can also make a liquid fertilizer with sunflower ash. To do this, mix 1 tablespoon of ash with 1 gallon of water and let it sit for a few days. Then, strain the mixture and use it to water your plants. This will provide your plants with a quick boost of nutrients.

Overall, sunflower ash is a natural and effective way to improve soil quality and promote plant growth. It is easy to use and can be incorporated into your gardening routine in a variety of ways.
