Fertilizing garden plants is important, no matter what type you grow. While many people do not pay too much attention to the caring of their annual flowers, such as sunflowers, it is actually important to make sure these flowers get the care they need.
Watering and fertilizing your sunflowers is especially important, as it produces large, colorful flowers, strong stalks and deep green foliage. So, let’s get started and fertilize those sunflowers!
What type of fertilizer should you use on sunflowers?
With sunflowers, you should use organic fertilizers. Fish emulsion is one type of organic fertilizer that works particularly well on sunflowers, and can be found for sale at most garden centers.
How should I prepare the fertilizer that I am feeding to my sunflowers?
It is different for each fertilizer product. With fish emulsion fertilizers, you typically need to dilute the contents of the bottle by mixing a small amount (often a tablespoon) into a gallon or so of water.
How should I apply the fertilizer to my sunflowers?
Dig a mote circling around the base of the sunflower plant, about 18-inches from the stem. Pour the fertilizer into this mote, and allow it to penetrate the soil. Avoid pouring the fertilizer directly onto the sunflower plant, as it could cause the plant to rot.
How often should I fertilize my sunflower plants?
For young plants, you should apply a very diluted solution of fish emulsion (about half-strength) weekly. Mature sunflowers should be fed a normally diluted fish emulsion fertilizer, once weekly.
Remember to water your sunflowers frequently, too. For more information, check out my article, “How To Water Sunflowers.”
Now that you know how to fertilize you sunflowers, why not go out there now and feed your plants? They will reward you well!
