When is the most suitable time to divide Clivia seedlings? A detailed explanation of the timing and steps for dividing seedlings

After Clivia propagates, the seedlings need to be divided once they grow out. Some flower growers think it is better to divide small seedlings, while others think dividing them after they grow a bit larger makes them easier to survive. What is the most suitable time to divide Clivia seedlings, and is there a difference in the seedling division time between seedlings from seed propagation and those from division propagation? For seedlings from seed propagation, divide when the seedlings grow to 2-3 cm; for division propagation, divide when the temperature is 15°C-22°C.

I. Timing of Clivia seedling division 1. Division after sowing

Clivia is generally sown quite densely, with small spacing between plants. The growth of the seedlings mainly depends on nutrients supplied from outside. If the nutrient supply is insufficient or the nutrients cannot be absorbed, the growth of the seedlings will be affected. However, if the seedlings are divided too early, the seedlings are fragile and have low resistance, and are not easy to survive if divided. The best time to divide the seedlings is when Clivia has just grown leaves and is 2-3 cm tall. When dividing, be careful not to damage the seedlings.

2. Division propagation and seedling division

Clivia propagation methods include division, and division means dividing the seedlings. If dividing Clivia by division, it can be done in all four seasons. In the area along the Yangtze River in the more southern regions, the weather warms up earlier, so it can be done when the temperature is 15°C-22°C; in autumn, it can be done when the fruit is ripe. In northern regions, seedling division in spring is later than in the south, and seedling division in autumn is earlier than in the south.

II. Preparation before dividing Clivia seedlings 1. Prepare flower pots and soil

The flower pot used for Clivia should have good air permeability. Generally, porcelain pots and ceramic pots are not used; clay pots can be used. The soil should first be sterilized by exposure to the sun. Humus soil or leaf mold plus coarse sand or perlite can be used. It must be sterilized in advance to prevent bacterial infection of the plant roots.

2. Charcoal powder and knives

When dividing seedlings, the plant roots will more or less be damaged, especially when dividing by division propagation. If a wound appears, charcoal powder can be applied to absorb moisture and prevent the roots from rotting; if it is seedling division after sowing, no knife is needed; if it is division propagation and the roots cannot be pulled apart, a knife must be used to cut them apart.

III. Steps for dividing Clivia seedlings

Now that we know the most suitable time to divide Clivia seedlings, and have prepared the materials and tools needed for dividing seedlings, the next step is to start dividing. Dividing seedlings from seed propagation is relatively simple; just transplant the seedlings directly with the soil. Here, the main focus is on the operation method for division propagation.

1. Gently pull the mother plant out of the pot as a whole, find the small plants to be divided, and slowly separate their roots from the root fibers of the mother plant. Each root of Clivia supports one leaf. If it can be pulled off directly, pull it off directly; if the root system is relatively large, a small knife can be used to cut it off.

2. Apply charcoal powder or soot to the separation wound to prevent the wound from becoming damp and rotting. Place it in a cool place and let it dry slightly to heal the wound.

3. When planting the plant, do not plant it too deep; the soil only needs to cover the plant roots. Cover the surface with a layer of sterilized fine sand, water to keep it moist. After about 2 weeks, the wound will heal completely and the plant will recover its vigor. Then cover with a thin layer of soil, and it can survive and grow new roots in 1-2 months.
