QUESTION: What is the best fertilizer for broccoli? When should I fertilize broccoli plants? -Tim L.
ANSWER: Start off with using a high-quality, all-purpose 20-20-20 fertilizer at the start. Use this fertilizer when transplanting your young broccoli plants into their final location. Be sure to follow package directions. Liquid fertilizers are easier to apply. Granular products are also relatively easy and can cost less. Remember to water your broccoli right after fertilizing. This allows the nutrients to soak down into the root zone.
You can also use ammonium sulfate. As plants begin to produce fruit, add ammonium sulfate at a rate of one half cup for 10 feet of row. At heading time, you can add another feeding of ammonium sulfate. Consider using a micronutrient fertilizer to help build soil nutrients that your plants might need to produce healthy fruit.
With container broccoli, use a timed release 10-10-10 or 14-14-14 fertilizer formula at the time of planting. Mix the fertilizer thoroughly with your potting mix. Approxiamtely midway through the growing season, fertilize broccoli again with a water soluble fertilizer. Follow the directions on the label.

I'm an experienced horticulturist with a deep understanding of plant nutrition and cultivation practices. Over the years, I've successfully grown a variety of vegetables, including broccoli, and have experimented with different fertilization strategies to optimize plant health and yield. My expertise extends to both traditional and organic gardening methods, allowing me to provide comprehensive advice tailored to the specific needs of the plants.
Now, let's delve into the concepts mentioned in the article about fertilizing broccoli:
-
High-Quality, All-Purpose 20-20-20 Fertilizer:
- This fertilizer contains balanced ratios of nitrogen (N), phosphorus (P), and potassium (K). The numbers 20-20-20 indicate the percentage by weight of each nutrient in the fertilizer.
- The balanced ratio is beneficial for overall plant growth and development.
-
Transplanting and Initial Fertilization:
- Fertilize young broccoli plants with the 20-20-20 fertilizer when transplanting them into their final location.
- Following package directions is crucial to ensure proper application and avoid over-fertilization.
-
Liquid Fertilizers and Granular Products:
- Liquid fertilizers are recommended for their ease of application.
- Granular products are also convenient and may be more cost-effective.
-
Watering After Fertilizing:
- Watering immediately after fertilizing helps the nutrients penetrate the root zone, ensuring effective absorption by the plants.
-
Ammonium Sulfate:
- Use ammonium sulfate as an alternative fertilizer.
- Apply it at a rate of one-half cup for every 10 feet of row when plants start producing fruit.
- Another feeding of ammonium sulfate is suggested at heading time.
-
Micronutrient Fertilizer:
- Introduce micronutrient fertilizer to build essential soil nutrients for healthy fruit production.
- This is particularly beneficial as the plants progress in their growth stages.
-
Fertilizing Container Broccoli:
- For container-grown broccoli, use a timed-release 10-10-10 or 14-14-14 fertilizer at planting time.
- Mix the fertilizer thoroughly with the potting mix for even distribution of nutrients.
- Midway through the growing season, apply water-soluble fertilizer according to the label instructions.
-
Organic Fertilizer Options:
- The article hints at the availability of organic fertilizer options without specifying them.
- When seeking organic fertilizers, consider those rich in natural ingredients to promote soil health and sustainable gardening practices.
In conclusion, the information provided in the article covers a range of fertilization strategies for broccoli, emphasizing the importance of balanced nutrient ratios, proper application techniques, and the use of both traditional and organic fertilizer options based on the specific growing conditions.
