How Many Tomato Seeds Per Hole

When planting tomato seeds, it’s essential to know how many tomato seeds per hole will deliver optimal growth. Generally, it’s recommended to plant 2-3 tomato seeds per hole. This ensures that at least one healthy sprout can grow into a mature tomato plant.

To increase germination, tomato seeds should be sown at about 1 inch deep with good seed-to-soil contact. Planting in a soil mix with enough nutrients and drainage holes and watering with a spray bottle or gently from the bottom can help. The seeds should also be kept at a warm room temperature and in full sun exposure, indoors or outdoors.

Thinning out the seedlings once they sprout and become stronger is also essential. Planting tomato seeds is a rewarding way to grow your own food and enjoy delicious fresh fruits. You can successfully grow healthy and thriving tomato plants with proper care and attention.

In our guide, you can learn more about how many tomato seeds per hole and what to do with your plants once they sprout. By the end, you’ll better understand growing tomatoes for a healthy crop, besides knowing how many seeds per hole you’ll need. (Learn How Long Does Sod Take To Root)

Factors to Consider

When planting tomato seeds, there are several factors to consider. If you wonder how many plants, you can get from a handful of tomatoes and how many seeds does a tomato have? The only seed in the Solanaceae family that is pubescent is found in tomatoes, making them special. Often, there are 150 to 300 or more seeds per fruit, or even more.

Here are some other important things to keep in mind:

Young Tomato Plants

Young tomato plants are delicate and require special attention. To keep them healthy, it’s important to plant only one or two seeds in one hole so you don’t overcrowd the seedlings.

Soil and Temperature

Grow tomatoes from seeds in warm, room temperature, well-draining soil. The soil should be nutrient-rich, with a pH between 6.0 and 6.8.

Seed Germination Rate

Many tomato seeds follow a different seed germination rate among all seeds. So, it’s important to plant seeds with more than one seed per hole. However, planting too many seeds leads to overcrowding. The experts of the most commonly grown plants recommend planting two to three seeds per hole and removing weaker sprouts should both seeds germinate.

Indoor or Outdoor Growth

Depending on your preference and climate, the number of tomato seeds
failing can be reduced if you start the seeds indoors. Indoor growth allows more control over temperature and moisture levels, while outdoor growth provides maximum sun exposure.

When growing tomatoes outdoors from seed, it’s essential to wait until after the last frost and to choose a location with well-draining soil and plenty of sun. Note: If you grow plants indoors rather than outdoors, the answer to how many tomato seeds per hole are required stays the same. You’ll still have seeds grow, while others don’t germinate.

Seed to Soil Contact

Proper seed-to-soil contact is essential for seed germination. Ensure all the seeds are planted at the correct depth, usually around 1/4 to 1/2 inch deep, and the soil is pressed firmly around the seed. A seed-starting mix or potting soil designed for seedlings can help ensure proper seed-to-soil contact.

Choosing a Tomato Seed

Before planting tomato seeds, choosing the right type of tomato seed is essential. Many different varieties of tomato plants, each with unique characteristics and uses, are available from the garden center.

Here are a few sub-sections to consider when choosing a tomato seed:


If you plan to use your tomatoes to make sauces, you may want to consider a variety of meatier tomatoes, such as harvest tomatoes, such as Roma or San Marzano.


If you plan to slice your tomatoes for salads or sandwiches, you may want to consider a variety of juicier tomatoes, such as Beefsteak or Brandywine. Once you have chosen the correct type of tomato seed, it is important to plant them correctly to ensure the best possible growth. To help support the young plants, you can use a wooden stick alongside each plant to prevent them from falling over.

Planting two seeds per hole increases the seed germination

How Many Seeds To Plant In One Hole?

Seed Germination Rate

Each tomato seed has a maximum germination rate, the percentage of viable seeds that will sprout.

According to expert gardeners, each seed has a 25% chance of the seed failing. Planting two seeds per hole increases the seed germination rate to 93.75%, making it more likely that at least one seed will germinate and grow into a healthy tomato plant.

Why More Than One Seed Is Recommended Per Hole

Planting multiple seeds of different types allows for a more diverse crop, as not all seeds are guaranteed to grow into the same kind of tomato plant. Growing Cherry tomatoes or Beefsteak offers two varieties to cover all requirements. (Read When To Fertilize Tomato Seedlings)

How Deep Should Tomato Seed Be Sown?

According to experts, tomato seeds should be planted between 1/8-1/4″ deep, as they are not very large.

How Many Tomato Seeds Per Pot?

The number of tomato seeds per pot depends on the size of the pot and the desired plant density.

A general rule of thumb is to plant 2-3 seeds per hole to sow tomato seeds. This ensures that at least one seed will germinate and grow into a healthy plant. You can plant more seeds per hole for larger pots to increase the chances of successful growth.

Seeds should be planted in soil with good drainage and plenty of nutrients. Keep the soil moist and at a cool room temperature to maximize germination rates. Once the tomato seedlings have sprouted, move them to a location with maximum sun and water them regularly with a spray.

Watering Requirements For Tomato Seeds

Tomato seeds require consistent moisture to germinate and grow into healthy seedlings. Here are some tips on watering tomato seeds:

  • Water the soil before planting the seeds to ensure good seed-to-soil contact.
  • Water the seeds lightly after planting to avoid washing them away.
  • Keep the soil surface moist but not waterlogged. Too much water can cause the seeds to rot.
  • Use a spray bottle or a watering can with a fine nozzle to avoid disturbing the soil and the seeds.
  • Water the seeds regularly but avoid overwatering. A good rule of thumb is to keep the soil surface moist to the touch.

Keeping the soil warm and moist is vital to ensure the seeds germinate. To create a mini greenhouse effect, you can cover the seed tray with plastic wrap or a clear lid. Place the tray in a warm room with a temperature of around 70°F to encourage germination.

If you planted more than one seed per hole, you’d need to thin out the weaker seedlings once they have grown their first true leaves. Use scissors or a stick to gently remove the short or weak sprouts, leaving the stronger ones to grow.

Tomato seed packets usually have extra seed, and we recommend planting two per hole.

Where Can Tomato Seeds Be Grown?

Tomato seeds can be grown indoors and outdoors, depending on your preference and your area’s climate. Indoor growth is ideal for those who want to start their tomato plants early or live in areas with cooler temperatures.

Outdoor growth is ideal for those with ample space and sunlight for their tomato plants to thrive. If you decide to grow tomato seeds indoors, you can start by planting them in seed trays or egg cartons filled with potting soil or a potting mix.

Ensure to water them regularly and keep them at a warm room temperature until the seeds germinate. If you decide to grow tomato seeds outdoors, you can sow them directly into the soil surface once the weather warms up.

Choose a spot with lots of sun exposure and good soil nutrients. Tomato seed packets provide specific instructions on growing tomato plants. Following these instructions and providing your tomato plants with ample sunlight, water, and nutrients, you can grow your own and enjoy the taste of homegrown tomatoes.

When To Plant Tomato Seeds

Tomatoes are warm-season plants whose seeds need warm room temperature to germinate. The best time to plant tomato seeds is in early spring, about 6-8 weeks before the last frost date in your area.

When planting tomato seeds, keeping the soil surface moist and warm is essential to encourage germination. To ensure good seed-to-soil contact, sow the tomato seeds about 1/4 to 1/2 inch deep in a well-draining potting mix or garden soil. You can plant tomato seeds indoors or outdoors, depending on your preference and the weather conditions in your area.

If planting seeds indoors, use a seed potting mix and sow two seeds per pot to increase the chances of successful germination. Adding coconut fiber or perlite helps retain moisture in the soil while improving tomato drainage.

If planting seeds outdoors, choose a spot with max sun exposure. Plant tomatoes seeds by two’s per hole, and if both seeds germinate, simply pluck out the shorter or weaker sprout. Most tomato seeds have a high germination rate, but it’s always a good idea to plant a few extra seeds in case some fail to germinate.

Watching as You Grow Tomatoes

Planting the Seeds

Whether you’re planting tomato seeds correctly in the ground or plants indoors, it’s important to create a hole about 1/2 an inch deep and 2 inches apart.

This way, you can ensure each tomato seedling has enough space to grow.


Tomato seeds germinate within five to ten days, provided they are kept in a warm environment.

Thinning the Seedlings

Once the tomato seedlings have sprouted, it’s important to thin them out to ensure that growing tomatoes have enough space to grow properly.

Staking the Plants

As the tomato seedlings grow taller, it’s important to stake them to provide support and prevent them from falling over. You can use wooden stakes or metal cages, so your tomato plants grow up toward the light.

Pruning the Plants

To encourage healthy growth and fruit production, it’s important to prune the growing tomatoes regularly. This involves removing suckers or small branches between the main stem and the leaves. This will help the plant focus its energy on producing fruit.

Harvesting the Tomatoes

Once growing tomatoes have ripened, it’s time to harvest them. Twist the tomato off the vine or cut it off with garden scissors. Enjoy your homegrown tomatoes fresh or use them in your favorite recipes.
