*Organic


What is it used for?

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.

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.

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.


Benefits

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.



Application rate?

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



How to apply?

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.


What are the benefits?


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.
