In general, Sagittarius should choose asexual propagation, because it prefers warmth, so it usually propagates with its terminal bud. When the temperature is 15 ℃, it starts to take root and sprout. When transplanting and growing, it's best to keep the temperature at 25 ℃ in the daytime, 15 ℃ at night, and 15 ℃ at the time of bulb formation. The temperature difference between day and night is large, and the light is OK, which is helpful for the development of bulbs. Generally, bulbs grow in about 30 days.
At the time of planting, the mature and hypertrophied terminal buds of its corm were cut and the seedlings were planted. In the growth period, we should make the leaf size around 1.4cm, and remember to add nitrogen fertilizer when growing new leaves. Wait until the bulbs grow up before the increase of phosphorus, potassium fertilizer. Remove the old yellow leaves, maintain its water balance, help to accumulate nutrients, during the period if there are pests, use the corresponding pesticides to kill insects, protect the normal growth of Sagittaria seedlings, so that cutting seedling breeding is completed.
Arrowheads can also be seeded to reproduce. First of all, we should choose the right soil, the best choice is some more fertile, better soil, the best is mud, and then choose some better seeds to plant in
The temperature should be well controlled, not too high or too low, to give it suitable light, but also sufficient moisture.
Because it prefers wet places, it should be watered more frequently before germination. After germination, it starts to slowly reduce the amount of water. When the seedlings grow out, it can be fertilized to ensure the nutrition demand of the roots. This kind of sowing and propagation is completed. Generally, this kind of propagation method is less, because seed propagation is used. In those days, only small bulbs could be formed.
