Tomatoes benefit greatly from foliar feeding, which can enhance their growth, fruit quality, and yield. Here are some of the best foliar fertilizers to use on tomatoes and how to apply them effectively.
1. Monopotassium Phosphate (KH2PO4)
Monopotassium phosphate is particularly effective during the fruit enlargement stage. It helps increase the sugar content and glossiness of the tomatoes and promotes fruit coloring.
Application: Mix 0.2% monopotassium phosphate with 0.5% urea and apply during the fruit enlargement stage.
2. Borax
Borax enhances the tomato plant's resistance to adverse conditions, increases fruit set rate, and promotes smooth fruit skin.
Application: Spray a 0.2% borax solution on the leaves during the initial flowering and peak flowering stages to increase fruit set rate by about 15%.
3. Calcium Chloride (CaCl2)
Calcium is essential for tomato fruit growth. Insufficient calcium can lead to blossom end rot. Calcium chloride is a commonly used calcium fertilizer.
Application: Spray a 0.3%-0.5% calcium chloride solution on the leaves every 7-10 days.
4. Triacontanol
Triacontanol enhances photosynthesis in tomato plants, promotes the synthesis and transportation of carbohydrates, accelerates maturity, and improves quality and yield.
Application: Spray a solution of 0.1-1 mg/L triacontanol on the leaves 1-2 times during the seedling and flowering-fruiting stages.
Important Considerations for Foliar Feeding Tomatoes
1. Focus on Spraying the Underside of Leaves
Tomato leaves have more stomata and water pores on the underside. Spraying the underside improves fertilizer absorption. Spraying only the top side is less effective.
2. Optimal Spraying Time
For best results, spray in the early morning or late afternoon to avoid leaf burn and seedling damage. If it rains after spraying, reapply the foliar fertilizer. The ideal interval for foliar feeding tomatoes is 5-7 days. Organic nutrients can be sprayed every 5 days.
3. Control the Amount
Adjust the foliar fertilizer amount based on the growth stage of the seedlings. Over-spraying can lead to excessive vegetative growth and even flower and fruit drop.
4. Combine with Disease Prevention
Foliar feeding during winter and spring can increase humidity in protected environments, leading to disease outbreaks. During prolonged cloudy weather, reduce the frequency of foliar feeding and add protective fungicides to lower disease incidence in tomato plants.
Conclusion
These guidelines provide a detailed overview of the best foliar fertilizers for tomatoes and their proper application methods. Following these steps will help you achieve healthy tomato plants with high-quality fruits and increased yields.

What Liquid Fertilizer Is Best for Tomatoes?
Choosing the right liquid fertilizer is crucial for promoting healthy growth and abundant harvests of tomatoes. This article explores some of the best liquid fertilizers recommended for tomatoes, along with their benefits and application guidelines.
Recommended Liquid Fertilizers for Tomatoes
There are several liquid fertilizers that are highly effective for tomatoes, providing essential nutrients for robust growth and fruit development. Here are some of the top choices:
| Fertilizer Brand | NPK Ratio | Benefits |
|---|---|---|
| 1. Miracle-Gro Water Soluble Tomato Plant Food | 18-18-21 |
|
| 2. Jobe's Organics Vegetable & Tomato Liquid Fertilizer | 2-5-3 |
|
| 3. Fox Farm Big Bloom Liquid Concentrate Fertilizer | 0.01-0.3-0.7 |
|
Each of these fertilizers provides specific benefits tailored to different needs and preferences, whether you prefer quick-release synthetic options or organic formulas that promote long-term soil health.
Application Tips
For optimal results, follow these general tips when applying liquid fertilizer to tomatoes:
-
Dilution: Follow the manufacturer's instructions for diluting the fertilizer in water.
-
Application Frequency: Apply liquid fertilizer every 2-3 weeks during the growing season, adjusting based on plant response and soil conditions.
-
Application Method: Apply directly to the soil around the base of the plants or use as a foliar spray for quick nutrient absorption.
-
Timing: Apply fertilizers early in the morning or late in the evening to minimize nutrient loss due to evaporation.
Conclusion
Choosing the best liquid fertilizer for tomatoes depends on your gardening goals, soil conditions, and preference for organic or synthetic products. By selecting a fertilizer with the appropriate nutrient balance and following proper application techniques, you can support healthy tomato plants and enjoy a bountiful harvest.
What Is the Best NPK Ratio for Tomatoes?
Choosing the right NPK (nitrogen, phosphorus, potassium) ratio is crucial for promoting healthy growth and maximizing yield in tomatoes. Different growth stages and soil conditions may require varying nutrient levels. This article explores the recommended NPK ratios for tomatoes and provides guidelines for optimal fertilization.
Recommended NPK Ratios for Tomatoes
The ideal NPK ratio for tomatoes depends on the growth stage and soil nutrient levels. Here are general guidelines:
| Growth Stage | Nitrogen (N) | Phosphorus (P) | Potassium (K) |
|---|---|---|---|
| Early Growth (Seedling to Vegetative) | High (N) | Medium (P) | Medium to High (K) |
| Flowering and Fruit Set | Medium (N) | High (P) | High (K) |
| Fruit Development | Low to Medium (N) | Medium to High (P) | High (K) |
Adjust the ratios based on soil test results and specific tomato varieties, as nutrient requirements can vary. Avoid excessive nitrogen during fruiting to prevent lush foliage at the expense of fruit production.
Fertilization Tips
Ensure effective fertilization by following these tips:
-
Soil Testing: Conduct regular soil tests to determine nutrient deficiencies and adjust fertilization accordingly.
-
Slow-Release Fertilizers: Use slow-release fertilizers to provide a steady supply of nutrients throughout the growing season.
-
Organic Options: Incorporate organic fertilizers such as compost or well-rotted manure to improve soil structure and nutrient retention.
-
Timing: Apply fertilizers before planting and throughout the growing season according to tomato growth stages.
Conclusion
Choosing the best NPK ratio for tomatoes is essential for achieving robust growth, healthy plants, and high yields. By understanding the nutrient needs of tomatoes at different stages and adjusting fertilization practices accordingly, you can promote optimal tomato production in your garden or farm.
