1. Soaking and Pre-sprouting Seeds
There are various methods to increase germination rates, but for beef tomatoes, it is recommended to soak the seeds in warm water (40–45°C) for 2–3 hours, then drain and wrap them in a damp towel. Keep them at a temperature of 20–25°C until the seeds crack, which indicates they are ready for sowing.
2. Seedling Germination
Sow the seeds evenly into seedling trays or nursery bags. Sprinkle a thin layer of ash over the seeds, followed by a layer of straw. This helps protect the seeds from insects and retains moisture. Place the trays in a well-lit area and water lightly to keep the soil moist. On average, seeds will germinate in 7–14 days.
3. Transplanting the Seedlings
Once the seedlings are about one month old, they can be transplanted following these steps:
– Step 1: Prepare the soil by mixing it with rice husks, coconut fiber, and organic fertilizers. Fill the mixture into a styrofoam box or pot, and create planting holes.
– Step 2: Place the seedlings into the holes (maximum 2 plants per box), ensuring the plant is buried deep enough so that half of the stem is below soil level. You may plant them upright or slightly tilted to stimulate root development.
– Step 3: Lightly press the soil around the base of the plant to secure it, then water gently to provide moisture.
1. Watering
When the plants are 7–10 days old, water them daily, using approximately 500ml of warm water (25–30°C) per plant. The best time to water is early morning or late afternoon.
Note: Always water from the base of the plant, not over the leaves, to prevent diseases such as leaf blight.
During the flowering and fruiting stages, water demand increases significantly. Insufficient water can cause the plant to wilt and drop its young fruits. However, avoid overwatering to prevent root rot and plant death.
During the rainy season, tomato fruits may ripen slowly or crack. You can use rice-washed water to water the plants and ensure proper drainage.
2. Staking the Plants
Tomato plants have weak stems and are prone to bending or falling, especially under the weight of the fruit or during windy and rainy weather. When the plant reaches 1.5–2 months old, provide support using bamboo stakes. Insert the stake into the soil and gently tie the stem to it, ensuring the plant stands firm and upright.
3 Pruning and Pinching
Sucker Pruning: Regularly remove side shoots (suckers) when they are 1–1.5 cm long to help the plant focus nutrients on fruit production.Tip: Break off suckers by hand rather than using scissors or fingernails. If using tools, always sterilize them first to avoid disease transmission.
Leaf Pruning:Remove old and yellowing leaves, as they consume more energy than they produce. This helps improve plant health and disease resistance.
Fruit Cluster Pruning: Keep only 4–5 healthy fruit clusters per plant to ensure high fruit quality. Too many clusters will reduce fruit size and yield due to nutrient competition. Always retain the main growing tip.
Topping (Pinching the main tip): Toward the end of the harvest season, pinch off the top of the plant to help it redirect nutrients to the remaining fruits, promoting larger and more evenly ripened tomatoes.
