Irrigation Tips for Greenhouse Tomatoes

Tomatoes have a high water demand and strong drought tolerance, making proper watering essential for healthy growth in greenhouses. Based on practical experience, here are the recommended watering techniques for greenhouse-grown tomatoes: First, adjust watering according to the different growth stages. During the early planting phase, it's important to water after 3–5 days, then again once the seedlings have developed. Watering should continue until the first fruit appears, when it's about the size of an egg yolk. In the early stage, the plant has fewer fruits, lower transpiration, and limited leaf growth, so watering should be done every 7–10 days with small amounts. As the plants grow and more fruits develop, the need for water increases. At this point, watering should be done more frequently—every 5–7 days—to maintain soil moisture without overwatering. During the harvest period, keeping the soil consistently moist helps increase fruit weight and quality. Second, consider the specific conditions of the greenhouse. In winter greenhouses where tomatoes are cultivated, planting typically occurs at the end of October. At this time, watering is usually avoided until the first fruit sets. Once the fruit begins to develop, watering can resume, and the plastic film should be covered to retain moisture. If needed, small amounts of water can be applied under the film to prevent temperature drops. As the weather warms, especially in early spring, it's important to increase watering to meet the growing needs of the plants. Timely irrigation ensures that the plants receive enough moisture for optimal fruit development. Third, observe the plant’s condition to determine when to water. Healthy tomato plants will have dark green, shiny, and flat leaves. If the heart leaves are not curled, and the leaves appear dark green, it indicates proper hydration. However, if the leaves sag slightly during sunny days, it may be a sign of water deficiency, and watering should be done promptly. On the other hand, if the leaves are overly stretched, thin, or show excessive wilting, it could indicate overwatering. Fourth, choose the right time of day for watering. It's best to water on sunny days, allowing the greenhouse to ventilate afterward to reduce humidity. Avoid watering in the afternoon, evening, or on rainy days, as this can lead to high humidity and promote diseases like downy mildew. Watering at noon should also be avoided, as it can stress the roots due to high temperatures. In hot weather, greenhouses can stay open later to allow for better air circulation. Finally, water before harvesting to improve fruit quality and commercial value. Proper irrigation just before picking ensures the fruits are firm, juicy, and visually appealing, which enhances their marketability.
