Sunflowers are lovers of acidic soil and with coffee grounds, the level of the soil acidity is enhanced. Coffee grounds being highly acidic will help to increase the acidity of the soil making it more suitable for the growth of sunflowers.

With coffee grounds, the pH of the soil is brought down. To apply coffee grounds to your sunflowers, get a cup of grounds and a gallon of water. Mix together and water the sunflowers with it. This helps in distributing the grounds and acid and gets the nutrients to the roots.


Feeding your sunflowers with coffee grounds can help lower the pH of the soil, attract worms and help feed the soil which is absolutely great for sunflowers.

Coffee grounds happen to be a favorite of the worms and this will benefit the sunflowers as the worms effectively aerate compact soil thus, improving the soil structure and drainage.

After the worms feed on the coffee grounds, the worm casts concentrate the valuable nutrients and minerals, thus, increasing nutrient availability to the roots of the sunflower.

You can also add your coffee grounds to your compost heap as it decomposes faster and can add valuable fertile material to be used as mulch for your sunflowers during the growing season.
