Accelerating Tomato Ripening in Plants: Tips and Tricks
In the summer heat, ensuring tomatoes ripen quickly and healthily can be a challenge. Here's a practical guide to help you achieve this:
## Accelerating Ripening in Hot Climate
1. **Water Management**: Maintaining a slight water stress can encourage tomatoes to ripen. Be mindful not to push the plant too far, as it could lead to disease. A touch of stress can signal the plant to focus on ripening existing fruits [1][2].
2. **Shading**: Direct sunlight can cause sunscald and delay ripening. Utilise shade cloth, sunflowers, or other plants to provide shade for your tomatoes [1].
3. **Ethylene Exposure**: Place tomatoes alongside other fruits such as apples or bananas in a bag. As these fruits ripen, they release ethylene gas, which expedites tomato ripening [1][3].
4. **Temperature Control**: Tomatoes thrive in warm conditions, so ensure they are placed in a warm spot to speed up the ripening process [3].
## Essential Nutrients for Tomato Growth
1. **Phosphorus**: Phosphorus plays a vital role during the flowering and fruit-setting stages. Use a fertilizer with a higher phosphorus content (e.g., 10-20-10 or 5-10-10 NPK) to aid fruit development. Apply it every 10-14 days during bloom formation [1][4].
2. **Potassium**: Potassium contributes to overall plant health and disease resistance. Use NPK ratios like 1-3-2 or 2-4-3 for enhanced fruit production [4].
3. **Nitrogen Regulation**: Reduce nitrogen once flower buds appear to prevent excessive leaf growth at the expense of fruit production. Lower nitrogen levels by 50-70% during flowering [4].
4. **Calcium**: Ensure sufficient calcium levels, particularly during the fruiting stage, to prevent "blossom-end rot" often caused by irregular watering [2].
By harmonising these environmental and nutritional factors, you can optimise your tomato plants for healthy growth and faster ripening in hot weather.
- Covering tomatoes with canopies made of garden film, polycarbonate, or plexiglass can protect them while conserving heat. - Insufficient sunlight and stresses (abiotic such as heat, drought, damage, or biotic like fungal diseases) can impact the speed of tomato ripening.
Additionally, using light-transmitting windbreak screens can safeguard tomatoes while allowing sufficient light. Infrared lamps can also help hasten ripening, and natural sources such as banana peel infusion, wood ash, and crushed eggshells can provide potassium, calcium, and other essential nutrients for tomato fertilization.
