  • Seed Germination Rate

Seed germination rates are the probabilities that a particular seed will emerge and grow into a plant. Different plant species have various germination rates. This implies that you should consider seed germination rate when you’re growing any seed.

Tomatoes for instance have a germination rate to be 75% which is fairly high. Therefore, if plant about 50 seeds, you should have about 37 of them germinate successfully. So, looking at this rate, it means that there is a one in four chance or 25% chance that the seed can fail to germinate.

Other growing factors such as the age of seed, temperature, and so on, can affect the rate at which the seeds germinate successfully.

Why More Than One Seed Is Recommended Per Hole

Because each tomato seed has about 25% chance of failing, adding an extra seed can reduce the chance of both failing. So, with two tomato seeds, you have about 6.25% chance of both failings. This means you’ve further increased the germination rate.

So, when you sow three tomato seeds per hole, you’ve drastically reduced the chances of the seed failing to 1.56%.

However, we advise you don’t overcrowd the hole if you’re planting bigger varieties of tomatoes. Then if you’re short of tomato seeds, then two seeds should be fine.

If after sowing two seeds and both germinate, just pluck out the weak or shorter one and leave the strong one.

Watering Requirements For Tomato Seeds

Moisture is a crucial factor for the growth of tomato seeds together with nutrients. However, you need to avoid over-watering the seeds. Over-watering can cause the water to drain down the soil’s nutrients. This can cause the germination rate to diminish.

The soil only needs to be moist for seed germination and you can make use of sprinkler to wet the soil. Water in the morning and before evening. But during the cold season, water only once then you can increase watering if the soil surface is dry.

Where Can Tomato Seeds Be Grown?

Tomato seeds need to be grown where they can get full or maximum sun exposure. Growing tomato seed in a container is a good idea depending on your climate. However, if your region is in the colder part, you should position the container with the tomato seeds on a windowsill for it to receive maximum sun exposure.

The container seed needs to be moist at all times and ensure the container has an adequate drainage hole to take out excess water. Also, ensure you provide the proper warm growing temperature for the seeds.

So, after the seeds have emerged into seedlings and the seedlings have attained at least 3 inches, they can be transplanted. You can transplant them into a bigger container or just transplant them outdoors in your backyard.

Once you’ve successfully transplanted the tomato seedlings in your backyard, it’s recommended to give them some support with a wooden stick alongside the plant. Alternatively, you can build iron or wooden mesh to support your plant. Doing this can further help prevent the end rot of tomatoes.

If you reside in a cold region, you need to protect your plant by covering them with polytunnel so that the growth of the tomato plan won’t be affected in an adverse way.
