How Early Should Tomato Seeds be Planted Inside?

The timing of planting tomato seeds inside can significantly impact the success of growing ripe and juicy tomatoes in your garden. Knowing when to start sowing seeds indoors can be a critical part of a healthy harvest. Tomato seedlings need enough time to grow indoor to become sturdy plants that can survive outside. Below are some things to keep in mind when planting tomato seeds inside:

Determining the Best Time to Plant

The best time to start tomato seeds inside depends primarily on two factors, including the length of your growing season and the tomato variety you plan to plant. Most tomato varieties take around 6 to 8 weeks to mature indoors before being transplanted outside, making it crucial to plant the seeds at the right time, with enough time to establish indoor and outdoor growth. Typically, planting tomato seeds indoors six to eight weeks before the last frost date in your area help establish the necessary growth and development.

Choosing the Best Tomato Variety

Not all tomato varieties are created equal, which is why having a deep understanding of the different types available can enable you to choose a variety that works best for you. A determinate, or bush, tomato variety typically requires less time to mature, and so you can plant this variety later than an indeterminate variety. Early producing tomato varieties, like Early Girl, are perfect for gardeners with short growing seasons because they don't require a lot of time to ripen.

Starting Seeds Indoors

The best time to start sowing tomato seeds is 6-8 weeks before the last frost date in your area. You'll need a few items, including planting soil, seed trays, tomato seeds, and grow lights. Plant the seeds directly in the soil, pushing them down ? -inch deep, spacing them 2 inches apart. After planting, cover the tray with a clear plastic dome or plastic wrap to help keep the soil warm and moist. Keep the seedlings in a warm and bright location, making sure that the soil stays moist. You can also use grow lights to supplement sunlight and ensure adequate lighting is available for the new seedlings. In 6-8 weeks when the plant has properly established it's time to move it outside for an even better harvest.

Final thoughts

Starting tomato seeds indoors can help you establish healthy and strong plants that produce abundant yields. Knowing when to start sowing tomato seeds, as well as choosing the best variety, can make all the difference in the success of your harvest. With the right timing and care, your indoor tomato seedlings will grow up to be sturdy plants that yield juicy and flavorful tomatoes in your summer garden!
