What are sunflowers and what does it need to grow best?
Sunflowers are annual plants that come from the family of Asteraceae. There are over 60 species of sunflowers, but the most popular one is Helianthus annuus. Sunflowers are usually grown for their seeds and petals. The flowers can grow up to 12 inches in diameter and reach a height of up to 15 feet.
Sunflowers are usually planted in the early spring and can grow in different soil types, but they prefer soils that are loamy, sandy, or gravelly. They also need full sun to grow best and should be watered regularly.
What are the advantages of fertilizing sunflowers?
Fertilizing Sunflowers can help them grow taller and produce more seeds. Fertilizing also helps the plants resist disease and pests. Proper fertilization will also improve the flavor of the sunflower seeds.
The most important time to fertilize sunflowers is when they are flowering. A balanced fertilizer with nitrogen, phosphorus, and potassium (NPK) will help the sunflowers produce seeds.
Which NPK ratio choose?
There are different NPK ratios to choose from when it comes to fertilizing sunflowers. The most common ratio is a 20-20-20, which contains equal parts of nitrogen (N), phosphorus (P), and potassium (K). However, you can also find 15-30-15 or 12-36-12 ratios. When in doubt, ask your local garden center for advice on the best NPK ratio for your sunflowers.
When and how to fertilize sunflowers?
Sunflowers are big plants and they need a lot of nutrients to grow big and healthy. You should fertilize your Sunflowers two or three times during the growing season. The first time you should fertilize them is when they have six leaves. You can use a balanced fertilizer for sunflowers like 20-20-20. The second time you should fertilize them is when the flowers start to form. Use a high phosphorus fertilizer like 0-46-0 to help the flowers grow big and strong. The third time you should fertilize them is right before they go into bloom. Use a nitrogen-rich fertilizer like 33-0-0 to make sure the blooms are nice and large.
The best time to fertilize Sunflowers is in the early morning or evening when the sun is not shining. This will help avoid leaf burning. Be sure to water them well after applying fertilizer so that the nutrients can be absorbed by the plants. Fertilizing sunflowers at the right time will help them grow big and strong.
Once you have applied the fertilizer, wait two weeks before applying again.
