How to sow grass flowers for germination
The editor introduces you to how to sow grass flowers for germination and some small experiences in plant cultivation related to the key techniques of grass flower seeding and seedling raising. Let's learn about it together below.
When we sow grass flower seeds at home, do we often encounter the following situations? For example, the seedlings tend to grow too tall, the seedlings don't sprout, or the new seedlings' leaves turn yellow. The germination period of plants is very vulnerable, and it is essential to take good care of them during this period.
Choose good seeds
When purchasing seeds, it's best to choose those from正规 channels. Buy seeds that look plump and have a coating on the seed coat. This is the prerequisite for ensuring the survival rate of the seeds.
Don't try to save money, as this can easily result in buying counterfeit goods. seeds from irregular sources often contain many shrunken seeds. These can lead to a low germination rate when planted in the ground.
Choose suitable soil for the seeds
Most seeds have a common characteristic when it comes to soil selection: they prefer loose and breathable soil. We can usually mix nutrient-rich soil and garden soil, and add sand, vermiculite, river sand, and perlite to increase the overall breathability of the soil.
Besides, we can also choose soil based on the pH preference of grass flowers. For example, Chrysanthemum, Astilbe, Allium, Jasmine, and Lupine prefer acidic soil, while Sweet Pea, Medal菊花, Hollyhock, and Baby's Breath prefer alkaline soil.
How to sow grass flowers for germination
Acidic soil is relatively fertile, rich in organic matter, which can effectively promote plant growth and development. It is suitable for the growth of most grass flowers. For example, leaf mold soil and pine needle soil.
Problems with sowing depth
Although plants rely on sunlight when growing above the ground, some seeds do not depend on sunlight when buried underground to germinate. Some can only germinate in the dark, away from light.
Therefore, when sowing, we need to cover the soil more thickly, with a thickness of about 2cm-3cm. For example: Chinese Red, Snapdragon, and Calycopea.
