Summary

In this video, Yacov offers a comprehensive guide on tomato fertilization, covering all stages from seed sowing to harvest. He provides a detailed fertilizer schedule and dosage instructions for optimal tomato growth, while also addressing how the same methods can apply to peppers and eggplants. The guide includes advice on soil preparation before planting, the use of various fertilizers like calcium nitrate and potassium monophosphate, and anti-stress treatments for plants. Yacov emphasizes the importance of crop rotation, proper nutrition, and soil care to ensure healthy, high-yielding plants. Additionally, he offers a free, detailed checklist for tomato cultivation to support gardeners.

Takeaways

• 😀 Proper fertilization is key for successful tomato growth, starting from seed planting to harvest. The process includes multiple stages of feeding the plants with specific nutrients.
• 😀 Fertilizer dosage should be carefully followed, usually 10 grams per 10 liters of water for root feeding, with adjustments for specific deficiencies.
• 😀 Tomato care principles apply similarly to peppers and eggplants, as they are related plants within the Solanaceae family and share similar nutritional needs.
• 😀 It's important to follow manufacturer instructions when applying fertilizers to avoid over-fertilizing and causing plant harm.
• 😀 Pre-planting soil preparation is critical, including adding organic matter like compost or manure, and using mineral fertilizers like azofoska for better soil health.
• 😀 Crop rotation is essential for tomatoes to prevent soil depletion and disease accumulation. Avoid planting tomatoes or related crops (peppers, eggplants) in the same spot for two consecutive years.
• 😀 Earth rest periods (fallow years or 'black fallow') help regenerate soil fertility, promoting better yields when cultivation resumes.
• 😀 During the early stages of seedling growth, use stress-relieving treatments like anti-stress sprays to support the plant's recovery from transplanting and environmental changes.
• 😀 Calcium and magnesium are crucial for healthy tomato growth, particularly to avoid blossom end rot (calcium deficiency) and yellowing leaves (magnesium deficiency).
• 😀 As tomatoes start fruiting, specific feeding strategies are needed, including high-potassium and low-nitrogen fertilizers to support fruit size and quality.
• 😀 In the final stage of tomato growth, emphasize nutrient balance, using fertilizers with calcium, potassium, magnesium, and boron to promote larger, healthier fruit while preventing issues like cracking.

Q & A

What are the three main stages in the tomato growth cycle that require different fertilizing strategies?

The three main stages are: 1) From seed sowing to transplanting seedlings, 2) From transplanting to fruit setting, and 3) From fruit setting to harvest. Each stage has specific fertilization needs to support the plant's growth and fruit development.

Why is crop rotation important for growing tomatoes?

Crop rotation is important to avoid soil depletion, reduce the risk of diseases like phytophthora, and ensure the soil remains fertile by preventing the accumulation of pathogens that affect solanaceous crops like tomatoes, peppers, and eggplants.

How should the soil be prepared before planting tomatoes?

Before planting tomatoes, it's recommended to add well-decomposed manure or compost (about one bucket per square meter) and mix it into the soil. Additionally, wood ash and a mineral fertilizer such as azofoska (which contains nitrogen, phosphorus, and potassium) should be applied to improve soil nutrition.

What is the role of calcium in tomato growth?

Calcium is crucial for the development of strong cell walls in tomato plants and prevents blossom end rot, a common problem caused by calcium deficiency. It also helps to increase fruit quality and prevent cracking.

How can you help tomato plants recover from stress during transplanting?

To help tomato plants recover from the stress of transplanting, it is recommended to apply anti-stress treatments like MegaFon, Epin, or HB-101. These substances help reduce the impact of transplanting stress and support healthier growth.

What type of fertilizer should be used for seedling growth?

For seedlings, the primary fertilizer should be calcium nitrate, which promotes strong vegetative growth by providing nitrogen and calcium. This helps the seedlings develop into robust, healthy plants.

Why should magnesium and boron be included in the fertilization schedule?

Magnesium helps with chlorophyll production and gives leaves a healthy green color. Boron is essential for proper flower and fruit development. Without adequate magnesium or boron, tomatoes can develop issues like yellowing leaves or poor fruit set.

What should you do if a tomato plant shows signs of nutrient deficiencies?

If a tomato plant shows signs of nutrient deficiencies, you can adjust the fertilization by increasing the dosage of the missing nutrient or applying treatments more frequently. For example, if the plant shows yellowing leaves due to potassium or calcium deficiency, increase the dosage of potassium and calcium-containing fertilizers.

How often should you fertilize tomatoes during the growing season?

Tomatoes should be fertilized regularly, with the frequency depending on the growth stage. During the early stages, fertilizers should be applied more often, around once a week or every five days. As the plant matures, you can reduce the frequency but continue feeding it throughout the growing season.

What is the significance of using complex fertilizers for tomatoes?

Complex fertilizers, which include a balanced mix of nitrogen, phosphorus, potassium, and microelements, provide tomatoes with all the necessary nutrients in a form that is easy for them to absorb. This helps to prevent deficiencies that could stunt growth or reduce fruit quality.
