Key points for seed germination
|
Ideal ambient temperature: around 25°C. |
Avoid water accumulation/flooding Although they need water, if the soil is too waterlogged (soaked), the seeds will rot due to lack of oxygen. |
|
Avoid soil drying The soil must be kept moist. If it is too dry, the seeds will not be able to absorb water and will fail to germinate. |
Until it sprouts, place it in a shady place for half a day. Avoid direct sunlight; place in a semi-shaded area (with diffused light). |
|
1. Spread the seeds evenly on the soil surface, avoiding overlapping. 2. Then gently cover with soil. |

Post-germination management
After germination and during the early stages of growth, water gently using a sprayer or similar tool to avoid washing away the seedlings. Water thoroughly only when the soil surface is dry.
 |
Thinning (shortening seedlings) Thin the seedlings to one plant per seedling. When planting in a No. 3.5 pot, once the seedlings begin to grow true leaves, keep only one strong seedling. |
 |
Lighting and ventilation management Manage it in a sunny and well-ventilated place. Sunlight is essential for plants. Ensure plants receive ample sunlight and maintain good ventilation to prevent disease. Regularly removing withered flowers (past blooms) will encourage plants to bloom for longer. |
Reasons for germination failure
Reason 1: Temperature
The germination temperature is around 25°C. Have you been able to maintain this temperature?
Reason 2: Soil moisture (dryness)
If the soil moisture dries out, the seeds that were originally moist will become dry , and the germination rate will decrease.
Reason 3: Excessive soil moisture
If the soil is too wet, the seeds will not be able to breathe and will rot.
Reason 4: Individual differences in seeds
If the seeds are too old, the germination rate will be poor.
Causes of plant wilting
Reason 1: Overwatering (root rot)
Reason 1: Overwatering (root rot)
Another reason is over-care and excessive daily watering.
If the soil is too wet, the roots cannot breathe and will rot and die. The roots will shrink and disappear, turn brown, and become thin and fragile.
Reason 2: Dryness
If you forget to water your plants, the soil will dry out and the plants will wither.
The leaves will become dry and brittle.
If there is still moisture in the leaves, water them thoroughly.
They might be able to recover.
Reason 3: Lack of sunlight (Extended)
If the seedlings do not receive enough sunlight after germination, the stems will grow too quickly and eventually break under the weight of the flower heads, causing the plant to wither. Make sure the plant receives ample sunlight and avoid overwatering.
Reason 4: The temperature is not suitable
Every plant has its optimal growth temperature.
Both excessively high and low temperatures can slow down plant growth and even cause plants to wither.
