Introduction
Tomato seeds are small, hard-shelled seeds that contain the genetic code for a tomato plant. Starting tomato seeds indoors is one of the best ways to get a head start on the growing season, as it allows you to begin the process months before the soil outdoors is ready for planting. Whether you’re a beginner or an experienced gardener, this guide will walk you through the steps for starting tomato seeds indoors.
Gather Supplies
The first step in starting tomato seeds indoors is to gather the necessary supplies. You’ll need potting soil, seed starting trays, and tomato seeds. Make sure to choose a potting soil specifically designed for seed starting, as it will be free of weed seeds and pathogens that can damage your young plants. For the seed starting trays, you can purchase them from a garden center or make your own using shallow containers like yogurt cups or paper cups.
Prepare the Trays
Once you have your supplies, it’s time to prepare the trays. Fill the trays with potting soil and lightly tamp down the soil. Then, make shallow depressions about 1/4 inch deep in the soil. This is where you’ll place the tomato seeds.
Plant the Seeds
Place one or two tomato seeds in each depression and cover them with a thin layer of soil. As a general rule of thumb, larger varieties of tomatoes may require two seeds per depression, while smaller varieties can usually get away with just one. Make sure to label the trays with the variety of tomato so you can keep track of which ones you’ve planted.
Water the Seeds
Once the seeds are planted, mist the top of the soil with water. You want the soil to remain moist but not soggy, so avoid overwatering. To do this, use a spray bottle and mist the soil every day or two. Avoid pouring water directly onto the seeds, as this can cause them to rot.
Provide Light
Tomato seeds need light to germinate, so place the trays near a sunny window or under grow lights. If you’re using grow lights, position the lights about 6 inches above the trays and leave them on for 14 to 16 hours a day. This will give the tomato seeds the light they need to sprout.
Monitor Growth
Check the trays daily for signs of germination, which usually occurs within 7 to 10 days. Once the seeds have sprouted, move the trays to a sunny location and provide additional light if needed. Continue to water regularly and monitor the growth of the seedlings.
Transplant the Seedlings
Once the seedlings have grown to a few inches tall, it’s time to transplant them into individual pots. Gently remove the seedlings from the tray and place them in small pots filled with potting soil. Water the newly transplanted seedlings and place them in a sunny location.
Conclusion
Starting tomato seeds indoors is a great way to get an early start on the growing season. By gathering the necessary supplies, preparing the trays, planting the seeds, providing the right environment, and transplanting the seedlings, you can successfully grow healthy tomato plants from seed.
