Germination is the first phase of a plant’s life cycle. To give your plants the best possible start in life, read on and find out exactly what happens to seedlings and what they need.
What do we mean by the germination phase?
During this phase a solid foundation is laid for what will, hopefully, grow into a beautiful and fruitful plant, which will give us a bountiful harvest. When the seeds germinate, the first tiny roots begin to develop. Most seeds germinate in the dark, in a reasonably warm place. However, some seeds germinate best in broad daylight, hence their name “light germinators”. Examples are lettuce, basil or dill, as stated in a RelationQue blog about light and dark germinators.
All seeds contain many nutrients that allow the seedlings to grow. However, even at this stage you can still help them as other important factors influence good growth.
What are the immediate needs of the plant?
As mentioned above, some seeds germinate in full daylight, while others prefer absolute darkness. This preference can vary considerably, so find out the requirements of your seeds, by reading the information on the packaging for example. Also, seeds need moisture and warmth (some more than others).
There are several ways to get seeds to germinate, such as by sowing directly in the garden or in a seedbed, or by using pots or seed trays. When sowing in pots or seed trays, it is best to use a substrate with a loose and airy structure where the roots will develop quick and strong. Atami offers Janeco-Light-Mix, which is a substrate enriched with perlite for extra aeration and is lightly fertilised. Sow your plants directly on it and they will develop healthy and strong roots right from the start.
Janeco-Light–Mix’s low EC is great for seeds and seedlings as they will have enough nutrients for the first couple of weeks, but without burning its tender roots. After that period, you can take over and feed the substrate with the fertiliser of your preference – it is recommended to start adding a root stimulator at this point.
How do I help the plant in this phase?
To ensure successful germination there are three essential conditions you should be aware of: water, oxygen, and temperature.
Firstly, the moisture level: too wet can mean fungus, too dry can mean the seed will dry out and will not germinate. So, make sure it is damp, not soggy!
Secondly, the temperature: Generally, seeds benefit from a stable, warm temperature to germinate. There are also seeds that need to go through a period of intense cold – which is known as stratification – in which case, they can be put in the fridge for as long as necessary to trigger further germination. As always, the best thing to do is to find out what each type of plant needs, so that you can achieve a high germination rate for your seeds.
When the seed germinates, the first thing that is formed is roots. Clearly, this part of its development is of utmost importance as the roots anchor the plant to the substrate and absorb the water and nutrients necessary for plants’ growth.
And in relation to oxygen, as mentioned above, we must provide the plants with a light, aerated substrate to encourage oxygenation of the roots.
To sum up, a strong root system provides the basis for a strong plant which means that it will bear more flowers and fruits. Atami offers different root stimulators that are specifically intended for well-developed and healthy roots.
Each range has its own root stimulator with its own characteristics. The root stimulators initiate the expansive growth of the root system and improve plants’ nutrients intake! We always say: great roots, better harvest!
How does the plant’s development continue?
We can distinguish several phases (or stages) in plant growth. If we are we can break these stages down even more specifically (such as pre-flowering, early flowering, late flowering…), but the essential stages of a plant’s development are these:
1. Germination and rooting phase.
2. Growth phase.
3. Flowering phase.
4. Ripening phase.
As you know, the germination and rooting phases are crucial, as without them there would be no plant to care for, but the other phases are just as important. In addition, each stage has its own characteristics, and as such, different needs and care. Atami offers you a wide range of products to help you give your plants what they need at every stage of their life so that they grow healthy and productive.

Frequently Asked Questions About Seed Start Guide for Healthy Plant Growth
What does the germination phase mean and why is it important?
The germination phase is the very first stage of a plant’s life cycle, when the seed begins to sprout roots and form its foundational structure. It matters because laying a solid root and growth base during germination increases the plant’s chances of becoming healthy, strong and able to produce a good harvest.
What are the key environmental requirements for seed germination?
For successful germination you need three essential conditions: moisture (soil damp but not soggy), temperature (steady and warm, unless the seed needs cold-trigger stratification), and oxygen (a light, airy substrate so roots get enough air).
How do I choose the right substrate for sowing seeds?
Use a substrate that is loose, airy and low in electrical conductivity (EC), so it supports fine root growth without ‘burning’ tender roots. A substrate enriched with perlite, for example, helps ensure good aeration and root development from the start.
Do all seeds require the same light conditions when germinating?
No, light requirements differ. Some seeds prefer darkness to germinate, while others (called “light germinators” like lettuce, basil, dill) need daylight to begin their process. Always check the seed packet for specific instructions.
What is stratification and when is it needed for seed germination?
Stratification refers to a required period of cold before certain seeds will germinate. If you’re dealing with such seeds, you may need to place them in a fridge for a time to trigger germination properly.
Why are strong roots so critical right from the seed stage?
Strong roots anchor the plant, absorb water and nutrients, and support the entire life cycle. If the roots develop well during germination, the resulting plant is more likely to be vigorous, bloom well and yield more.
How should I manage moisture during the germination phase?
Keep the substrate consistently damp, not soggy. Too much water can cause fungus; too little and the seed dries out and fails to germinate. Finding the correct moisture balance is key.
What should I do after the seedlings have developed initial roots?
Once your seedlings show healthy root growth, you can begin to add a root stimulator and gradually start feeding the substrate with nutrients and fertilisers. This supports their transition into the growth phase.
What are the major growth phases of a plant after germination?
According to the article, the plant’s life cycle can be divided into four main phases: (1) Germination & rooting, (2) Growth, (3) Flowering, and (4) Ripening. Each phase has distinct requirements that need to be addressed for optimal development.
How can good seed-start practices improve my overall plant yield?
By giving seeds the right start. Proper substrate, moisture, temperature, aeration, light and root stimulators. You establish a healthy plant foundation. That results in stronger plants, better nutrient uptake, more flowers and fruits, and ultimately a higher quality harvest.
