Cutting seedling with corm

Temperature and light

Sagittarius should generally choose asexual reproduction, because it prefers warmth, so it usually uses its top bud for reproduction. When the temperature is 15 ℃, it starts to take root and sprout. During planting and stem and leaf growth, it is best to keep the temperature at 25 ℃ during the day and 15 ℃ at night, and the temperature during bulb formation should be controlled at about 15 ℃. The temperature difference between day and night is relatively large, and the light is OK, which is conducive to the good development of bulbs. Generally, bulbs grow in about 30 days

Fertilization and medication

When planting, cut the mature and hypertrophic terminal bud of its bulb and insert it to cultivate seedlings. During the growth period, we should keep the size of leaves at about 1.4cm, and remember to add nitrogen fertilizer when growing new leaves. Wait until the bulb grows up and increase phosphorus and potassium fertilizer. Take off the old yellow leaves to maintain its water balance and help accumulate nutrients. If there are pests during the period, use corresponding pesticides to kill the insects and protect the normal growth of arrowhead seedlings. In this way, cutting seedling raising is completed

Breeding by sowing

Soil selection

Sagittarius can also sow seeds to reproduce. First of all, we should choose suitable soil. It's best to choose some fertile soil with better soil quality, preferably muddy soil, and then choose some better seeds to plant and sprinkle

Temperature

The temperature should be well controlled, not too high or too low. Give it suitable light and sufficient water

Watering

Because it prefers wet places, it should ensure sufficient water. It should be watered more frequently before germination. After germination, it begins to slowly reduce the amount of water. When the seedlings grow, it can apply fertilizer to ensure the nutritional needs of the roots. In this way, sowing and reproduction is completed. Generally, this method is less used, because seeds can only produce small bulbs in the same year
