How to Grow Tomatoes in a Greenhouse
Starting your own tomato plants in a greenhouse is rewarding and can extend your growing season. Here's a guide to help you succeed:
1. Choose the Right Variety: Select tomato varieties suitable for greenhouse cultivation, such as 'Sungold' or 'Moneymaker.'
2. Prepare the Soil: Fill raised beds or containers with a well-draining potting mix rich in organic matter. Test the pH and adjust to 6.0-6.5.
3. Sow Seeds or Start Young Plants: Sow seeds 6-8 weeks before the last frost. Alternatively, purchase 6-8-week-old seedlings.
4. Provide Adequate Light: Tomatoes need plenty of sunlight. Supplement with artificial lighting if necessary to ensure 12-14 hours of light per day.
5. Fertilize Regularly: Feed plants a balanced fertilizer every 2-3 weeks. Avoid over-fertilizing.
6. Water Consistently: Water plants deeply and evenly when the soil is dry to the touch. Avoid overwatering.
7. Control Temperature and Humidity: Maintain temperatures between 65-75°F (18-24°C) during the day and 55-65°F (13-18°C) at night. Humidity should be around 50-70%.
8. Trellis or Stake Plants: Support plants with a trellis or stakes to prevent them from sprawling and improve air circulation.
9. Pollinate: Tomatoes require pollination. Gently shake plants or use an electric toothbrush to simulate wind and transfer pollen.
10. Harvest Regularly: Once fruits begin to ripen, harvest them promptly to encourage further production.
