What is the appropriate dilution ratio of urea to water?

Urea is a high-concentration, fast-acting fertilizer. Therefore, it is recommended to use 1 gram of urea to mix with 200-500 grams of water when watering flowers. Too concentrated fertilizer will cause root burn and seedling injury; too light a proportion will not provide good fertilizer effect for flower pots.

For this, flower lovers need to carefully control the amount of fertilizer applied when growing flowers, apply small amounts of fertilizer frequently, and strive to achieve a "twice the result with half the effort" fertilization effect.

Precautions for applying urea to flowers at home

1. It is forbidden to mix or apply it simultaneously with alkaline fertilizers.

Alkaline fertilizers include lime, wood ash, calcium magnesium phosphate fertilizer, etc. If these alkaline fertilizers are mixed with urea or applied at the same time, the nitrogen element in the urea will be converted into ammonia and volatilized.

Therefore, when applying fertilizer in summer and autumn, the application of urea and alkaline fertilizer should be separated by 3 to 5 days, and when applying in winter and spring, the interval should be 7 to 9 days.

2. It is forbidden to apply urea to potted flowers and trees for a long time

   Urea should be applied in combination with organic fertilizers and phosphorus and potassium fertilizers to meet the needs of flowers and trees for various nutrients. Doing so can also speed up the transformation and decomposition of urea's nutrients and improve the utilization rate of urea.

In addition, urea should not be used as seed fertilizer, otherwise it will make the seeds lose their germination ability and endanger the germination and development of seedlings. If it must be used as seed fertilizer, the "close" contact between seeds and urea should be avoided and the amount used should be controlled.

3. Do not water immediately after applying urea.

   Generally, watering should be done 2-3 days after fertilization in summer and autumn, and 7-8 days after fertilization in winter and spring. Otherwise, fertilizer loss will cause waste.

When applying urea to flowers and trees grown in the courtyard, it cannot be done before heavy rain comes. It can only be used when there is no rain within 2 to 3 days, so that the soil can firmly absorb nutrients and the flowers and plants can fully absorb nutrients.

4. Avoid excessive or frequent use

   Urea has a very high nitrogen content and a single nutritional component. Be sure not to apply too much, so as to avoid fertilizer damage, root burn and seedling injury.

If it is used as a fertilizer liquid for foliar spraying, avoid using a concentration that is too high, and 0.5% to 1.5% is appropriate. Otherwise, a high concentration will burn the leaves and cause poisoning to the flowers and plants.
