Importance of good germination
Germination is the first step in the development of any plant and, if done correctly, ensures healthy growth. A mistake at this stage can result in weak seedlings or even the complete loss of the seeds. Ensuring that you create the ideal conditions from the start is key to the success of your crop.
Common mistakes in seed germination and how to avoid them
1. Use of low-quality seeds
Using old seeds or seeds from dubious sources can drastically reduce germination rates. To avoid this problem, make sure you buy fresh seeds from reputable suppliers and store them in a cool, dry place.
2. Incorrect choice of substrate
The substrate must be light, airy and with good moisture retention capacity. Soil that is too compact or with poor drainage can prevent the seed from absorbing the oxygen needed to germinate.
3. Lack or excess of water
Excess water causes root asphyxia and fungal growth, while lack of moisture prevents the seed from awakening. The key is to keep the substrate slightly moist, without puddles.
4. Inadequate temperature
Most seeds require temperatures between 18°C and 25°C to germinate properly. If it is too cold or too hot, germination will slow down or even stop.
5. Poor lighting
Some seeds need light to germinate, while others prefer darkness. Learn about the light requirements of each type of seed and provide adequate light once the seedlings emerge.
6. Lack of oxygenation in the substrate
A very compact substrate prevents the roots from breathing. Make sure the medium is porous and contains elements such as perlite or coconut fiber to improve oxygenation.
7. Contamination by fungi or bacteria
Using contaminated substrates or dirty tools can encourage the appearance of pathogens. It is advisable to disinfect the substrate and use clean water to avoid problems.
8. Not respecting germination times
Each species has its own germination rate. Being impatient and handling the seeds too early can damage them. It is essential to know the approximate times for each type of seed.
9. Poor handling of seedlings
Seedlings are fragile and handling them incorrectly can damage them. When transplanting, use appropriate tools and handle the root and stem carefully.
10. Use of fertilizers at an early stage
Seeds contain the nutrients needed for their first few days of life. Applying fertilizers too early can cause overfeeding and root burn.
Tips to improve germination rate
Select quality seeds
Always purchase seeds from reputable distributors and check their expiration dates before using them.
Choose the right substrate
Use a light, well-drained and aerated substrate, rich in organic matter to promote growth.
Keep humidity at optimal levels
A useful trick is to use a spray bottle to maintain humidity without flooding the substrate.
Controls the temperature of the environment
If necessary, use heating mats or electric germinators to maintain a stable temperature.
Provides the necessary light
If you germinate indoors, use plant-specific LED lights and keep them at the proper distance.
Avoid contaminants in the germination area
Clean your tools and wear gloves when handling seeds and seedlings to prevent disease.
