People who grow flowers usually pay special attention to fertilizing or replenishing the flowers and want to try everything. It's right to replenish plants with nutrients, but don't add them blindly, otherwise it's easy to make plants lose their lives.

This is not, recently, Huahua saw someone strongly recommend watering flowers with urea, saying that watering flowers with urea can promote plant growth, increase leaves, plant growth, the better and so on have a lot of benefits! Huahua understands the eagerness of flower lovers and wants their own plants to grow vigorously and energetically, but with regard to urea watering flowers, Huahua has some suggestions to tell you. If you are going to water the flowers with urea, read on. Maybe this article will help you.

1. Urea is actually fertilizer, which is no different from phosphorus, nitrogen and potassium fertilizer. When you choose to water flowers with urea, you should choose urea with smaller particles to dilute it with water. The ratio is about 1 / 5, 000, otherwise the roots of plants will be burned easily if the concentration of urea is too high.

two。 After watering urea, you can't water it directly, otherwise the nutrients of urea will be lost before it is absorbed by plants. It can be watered 2 to 3 days after urea is watered in summer and autumn, and about a week after urea fertilizer is applied in winter and spring.

3. Urea fertilizer as seed fertilizer, urea can make seeds lose the ability to germinate, and even harm seedlings. Don't use urea on seedlings and seeds.

4. When using urea fertilizer, you should pay attention to it. It is best not to apply it on the surface of the basin soil. Urea is easy to volatilize. Only when applied in the depths of the soil can plants better absorb nutrients.

5. Urea cannot be used alone as a fertilizer, but should be used in conjunction with other organic fertilizers or compound fertilizers, so that plants can absorb more nutrients.

6. High concentration of urea can not be sprayed directly on the surface of the leaves, this operation can burn the leaves.

7. Do not use too much urea, urea contains nearly half of the nitrogen content, nitrogen nutrients are very high, if too much fertilization will cause waste or bring some adverse effects. 、

8. When using urea, it should be used about a week before other nitrogen fertilizers are used to avoid using other nitrogen fertilizers at the same time and the nitrogen content is too high.

9. Urea cannot be fertilized with alkaline fertilizer. It may result in increased volatilization of urea, so you have to stagger the time when using urea. The staggered time in spring and winter is about a week, and the staggered time in summer and autumn is about 3-4 days.

All right, these nine points are what Huahua wants to tell you to pay attention to before using urea to water flowers. I hope you will watch carefully and apply fertilizer according to the specific conditions of your own plants. I also wish your plants can grow vigorously.
