Cultivation of Tomatoes

Tomatoes are warm-season plants that thrive in sunny, well-drained soil. They are relatively easy to grow and can be cultivated in gardens, containers, or greenhouses.

Planting

• Season: Tomatoes are typically planted in the spring after the last frost, when the soil temperature is consistently above 60°F (15°C).
• Spacing: Plants should be spaced 24-36 inches apart in rows spaced 3-4 feet apart.
• Germination: Tomato seeds germinate in 5-10 days under optimal conditions.

Care

• Watering: Tomatoes require consistent moisture, especially during fruiting. Avoid overwatering to prevent root rot.
• Fertilization: A balanced fertilizer can be applied at planting and again when the plants begin to flower.
• Support: Use stakes, cages, or trellises to support the plants and keep the fruit off the ground.
• Pest Control: Common pests include aphids, whiteflies, and tomato hornworms. Organic pest control methods, such as neem oil or insecticidal soap, can be used.

Harvesting

Tomatoes are ready to harvest 60-85 days after planting, depending on the variety. They should be picked when fully colored and slightly soft to the touch.
