What is the hardest step you find in growing a plant? Germinating seeds, right? (at least for me it is) like choosing which seed, which type, how deep to dig, how much time to wait for it germinate, how much water to give, kind of a brain-rotting task if you ask, but exciting too, as it’s different from a tech or digital activity which we normally do, growing a plant from scratch might be interesting than it seems, come lets find out.

In this blog, we will learn how to germinate seeds by examining the factors that affect seed germination.

Let’s start by understanding seed germination.

Seed Germination – 

Seed germination is nothing but a seed sprouting into a plant, or on a small level, we can say into a seedling, like an embryo growing into a human baby. A seed, under the right conditions, in the right environment, with favourable temperature, and with a decent amount of moisture, starts its metabolic activities and grows into a healthy, germinated plant.

A good germination of the seed is very important, as it will turn into a plant tomorrow; it needs the right care. 

Now, let’s examine the factors that affect seed germination. 

Factors Affecting Seed Germination

So these factors affect seed germination just as our body is affected by a healthy diet; it won’t stay good without these important factors:

1. Oxygen – 

Oxygen is necessary for the respiration of germinating seeds, as it provides the energy needed for seed growth. The potting mix shouldn’t be too compact, allowing sufficient space for oxygen to pass through. 

2. Temperature – 

A suitable temperature for a particular seed is very important to know, as it would not germinate out of its optimal range. Sunflowers require low temperatures for germination, and on the other hand, pepper requires soil temperature from 70°F (21°C) up to 95°F (35 °C) for optimal sprouting. The best temperature, which normally suits almost all seeds, is between 20 and 30 °C. 

3. Water – 

We can say that germination starts with water, as it starts with imbibition, where the seed absorbs the water. But afterwards, when it is used for soil moisture, the right amount should be kept in mind, as if excess watering occurs, it will result in reduced oxygen, and the soil will become waterlogged, which will not be beneficial for germination, and if the amount of water is less than what is required, then it will hinder sprouting.

4. Light – 

Like temperature, different seeds have varying sensitivities to light; seeds that germinate beneath the soil surface require very little light compared to those that germinate at the soil surface. The growing of the plant phase requires light, but in seed germination, less light also works. The plants that grow in less light are normally tall and have short leaves. As they are always in need of light.

5. Soil – 

Soil is the medium in which the seed has to grow, so it’s important to check whether it’s compatible or not. Loamy soil is suitable for seed germination as it has the best texture for seeds to grow, neither excessively clay-rich nor overly sandy. Soil arrangement should be well-aggregated so the seeds can breathe beneath it; a compact arrangement restricts respiration, which is essential for growth.

 Soil pH is also an important aspect to keep track of, as it affects nutrient availability and enzyme action. Most seeds germinate well in (pH 6-7).

6. Seed Quality – 

When we want our seed germination to be successful, we should invest money wisely in seeds. If the seeds are cheaper or old, it may be a possibility that the seeds are not viable, which means that their embryo is not alive. It may look normal from the outside, but it won’t be helpful in your germination.  And personally, I advise going for a bigger-sized seed as they are well-filled, have more storage, which ensures better germination.

Vigorous seeds germinate quickly and have more strength than low-vigour seeds, like a passionate student who is eager to achieve their goal.

So now let’s learn germination step by step…

How To Germinate Seeds?

We have learnt factors affecting germination, and you should be aware of that before starting. Now comes the main process: 

1. Preparation of Seeds for Germination – 

Before purchasing a seed packet, carefully review the details on the back of the packet, so you don’t get any surprises later.

After choosing the seed, soak the seeds in water for 8-16 hours, it is done to soften the hard seed coat and allow the seed to absorb water quickly. After soaking, drain the excess water.

2. Growing Medium Arrangement – 

Now, after the seeds are ready, prepare the soil accordingly, as it has to provide every kind of support to the seed to grow; its moisture retention should be balanced, otherwise the seed may rot or dry out; it should be loamy.

The potting mix should not be too compact to restrict aeration. Keep these tips in mind while mixing soil with water.

And after preparing the soil, choose a container. Seedling trays work well, as they are very suitable, and it has compartments for seeds, but you can use a different one that has proper drainage for excess water; it should be of moderate depth and free of impurities.

3. Seed Sowing – 

Seed sowing arrangement differs according to the size of the seed; for example, if the seeds are tiny, like poppies or fireweed, they should not be sown very deep but should be sprinkled on the surface, as these seeds need more light and oxygen. And if the seeds are large, like coconut or mango, they can be sown deep as they can survive with less light. 

While spreading the seeds, it should be done evenly throughout the area, or else it would be overcrowded in a particular place and overcrowded seeds compete for resources, which would result in weak seedlings.

Research shows that the seed should be sown at a depth equal to twice or thrice the diameter of the seed.

4. Creating a Favourable Environment – 

 Establish an environment that is helpful for the growth of the seedling after the seed has been planted. While some seeds can grow in complete darkness, others require light, so arrange the container so that the windows face west.

Watering should be done evenly and as needed; too little or too much will negatively impact germination. It should be lightly covered with a cardboard or a plastic bag to keep it safe from any physical or natural activity.

5. Transplanting the Seedling –

 It is the final process of seed germination. After the seed grows into a strong root system or develops 2-4 true leaves, it is transferred from the potting medium to its final growing place.

But before transplanting our baby into this outside world, we have to make our young seedling is a rough-tough guy who can survive in this cold world(just kidding), we have to train our young seedling slowly and gradually by inviting them outside, like for day 1, keep them outside for one hour, then the next day for 2 hours, for exposing them to sunlight and wind. It is commonly called hardening of the seedlings.

Only transplant those seeds that appear healthy, disease-free, strong, and can withstand challenging conditions.

Helpful Reminders – 

• For the first step of soaking the seeds, DO NOT over-soak your seeds, or else they will rot, and your germination will end before starting.
• Always place multiple seeds in your potting mix to avoid the possibility of failure.
• After using seeds from the seed packet, store the remaining seeds in a dark and cold place so they won’t lose their germination capability.
• After setting the germination setup, check its activity regularly to track its growth and provide it with moisture as needed to avoid a drought.

Conclusion – 

Seed germination is a challenging but worthwhile process. I didn’t have any support when I first started, but thankfully, you guys do, so what are you waiting for? Run to the store, pick up a packet of seeds, and begin your germination journey.
