5. How to make tomato seeds germinate faster?

The average period of germination of tomato seeds is 6-11 days. This process can be boosted faster in various ways. First, let’s have a look into the factors that tell about the tenure of seed germination. 

Soil: Soil is one of the important factors affecting seed germination. Tomato seeds can germinate when the soil temperature is between 65degree Fahrenheit to 85 degrees Fahrenheit.

When planting tomato seeds, we need to check whether the temperature of the soil lies between 65 to 85 degrees Fahrenheit or not, and also, the pH of the soil lies between 6-7 or not. The seeds germinate best at 50 degrees Fahrenheit air temperature. The negligible number of seeds germinate at temperatures below 50 degrees Fahrenheit.

This is a natural protective measure that doesn’t let the sprouts grow in such a temperate where they cannot survive. Also, if the temperature is higher than optimum, it limits the growth of sprouts.

A soil temperature higher than 95 degrees Fahrenheit doesn’t let sprouts grow effectively since such temperature condition leads to molding. If a very low temperature is noticed, a heating tray can be kept under the seed tray. 

Humidity: It is also an essential factor that controls seed germination, and this must be checked. If humidity is much below the optimum level, the air and soil around won’t contain much water vapor, leading the seeds to die due to dry conditions.

Moreover, excessive moisture content than required may lead the seeds to dampen, and the seeds become prone to several pathogenic attacks that can cause infection. 

If there is trouble keeping the air and soil condition humid, a humidity dome can be used. It traps the humidity from the surroundings and keeps the air around the seeds moisturized. A humidity dome is effective in causing a higher number of seeds to germinate.

Another method that can be used is surrounding the seeds with a plastic that keeps the seeds wet for a longer duration. We must take care that the plastic doesn’t touch the soil. 

Air circulation: Fresh air circulation is very important for the seeds to germinate. To know when to plant tomato seeds, you must choose a space with sufficient air around. Extremely wet soil with low air circulation leads to dampening and can kill the seeds.

We can take two preventive measures to protect them from such conditions. Firstly, we can apply a humidity dome by just moisturizing the soil to keep the air around at the required humidity level. We must take care not to wet the soil. Another way is to keep the soil loose to allow air and water to pass through it. These are essential elements for seed germination.

Keep the soil moist. Also, try to maintain the humidity of the air around. If needed, make use of a humidity dome or plastic covering to maintain optimum humidity. 

Dark areas are best for seed germination. Once the sprouting has occurred, supply the seeds with an adequate quantity of light. Before germination, keep the seeds in the dark, and they need overhead light post-germination. Otherwise, the seeds would get deformed in their shape.

To understand when to plant tomato seeds, you should know how deeper you place the seedlings into the soil. It is also a determining factor the duration of germination. A gap between two consecutive plantings must be sufficient.

Cover the bowl containing the cup with plastic. This creates optimum humidity around the seeds. Keep the cups in a place where it receives 70-90 Fahrenheit temperature for about two weeks.

After germination, remove the bowls and transfer the plants to a warm region of the house where it gets about six hours of regular sunlight. Supply water to the seedlings regularly.
