Tomato seedlings are delicate and require proper care in order to thrive. However, even the most experienced gardeners can make mistakes that can severely impact the health and growth of their seedlings. To help you avoid these common mistakes, we have compiled a list of 20 common errors that can ruin tomato seedlings.
One of the most common mistakes is overwatering. Tomato seedlings need to be kept moist, but not waterlogged. Overwatering can cause root rot, which will kill the seedlings. When you water the seedlings, be sure to allow the top inch of soil to dry out before watering again.
Conversely, underwatering can also be harmful to the seedlings. The soil should be moist but not dry. If the soil is too dry, the seedlings will wilt and may not recover. Be sure to check the soil regularly and water when necessary.
Not Enough Light
Tomato seedlings need at least 6 hours of sunlight per day. If they don’t receive enough light, they will become spindly and weak. If you’re growing seedlings indoors, be sure to provide them with bright, direct light. You can also use artificial grow lights if necessary.
Too Much Heat
Tomato seedlings don’t like extreme heat. If the temperature is too high, they will become stunted and may even die. If you’re growing seedlings indoors, be sure to keep the room temperature between 65 and 75°F.
Poor Soil Quality
Tomato seedlings need well-draining soil that’s rich in nutrients. If the soil is too heavy or has poor drainage, the seedlings will struggle to grow. Be sure to use a quality seed-starting mix and amend the soil with compost if necessary.
Pests and Diseases
Tomato seedlings are susceptible to pests and diseases, such as aphids, whiteflies, and damping off. To prevent these issues, be sure to monitor your seedlings regularly and take action if you notice any. You can try Pest Organic Disease Control
7. Sowing seeds too deeply:
When planting your seedlings, make sure to plant them at the same depth as they were in their seed tray. Planting them too deep can cause them to rot or not grow properly. Sow seeds no deeper than 1/4 inch to ensure that they have enough light to germinate.
