It is not recommended to use expired Home Gardening Concentrate All-Purpose Nutrient Solution for watering flowers.

Although this nutrient solution can promote plant growth, it may have gone bad, especially if it has expired for a long time. The use of expired nutrient solutions may have a negative impact on plants or even cause them to die. In addition, even if the nutrient solution has not expired, care should be taken to use it correctly according to the recommendations on the instructions and avoid overuse or mixing of different types of fertilizers, which may cause over-fertilization or other adverse effects on the plant.

Don't throw away the beer at home after the expiration date, it can be used to make your own nutrient solution to water the flowers. Beer is rich in carbon dioxide, which is an essential nutrient for plant metabolism, and it contains sugar, protein, phosphate, amino acids, etc., which are easy to absorb nutrients for flowers.

Summary. OK. Dilute it with water first to avoid fertilizer damage due to high concentration, which may directly cause the death of flowers.

Rice water is very common in life, many people don't know that it has a great effect, using rice water to water flowers, can make the soil loose and breathable, and can supplement some of the nutrients needed by flowers.

Can flowers that bloom in all seasons be watered for a long time with universal nutrient solution and phosphorus and potassium polynutrient solution?

The nutrient solution is suitable for watering all kinds of flowers. However, when watering, we should pay attention to the method and control the proportion of water distribution. Generally, it is diluted 200 times to irrigate, and the watered plants can be better absorbed after dilution, and they can be watered thoroughly at one time.

In addition, you should also pay attention to the frequency of watering, not too often, otherwise the roots will be burned.

Don't be too diligent, or you will burn the roots.

Four seasons flowers with nutrient solution watering, how long the interval is appropriate, spring and summer is the peak season for plant growth, the amount of fertilizer is larger, generally 1-2 weeks of fertilization 1 time. In autumn, the amount of fertilizer should be gradually reduced, 1 2 months can be watered 1 time, low temperature in winter, the plant enters the dormant period, stop growing, no need to fertilize, if in a warm room, you can apply less.

1. When preparing the nutrient solution, avoid using metal containers, let alone use it to store the nutrient solution, and it is best to use glass, enamel, and ceramic utensils.

2. When preparing, it is best to melt all kinds of inorganic salts with a small amount of warm water of 50, and then pour it into the water containing 75% of the specified capacity in the order of the items listed in the formula, stir while pouring, and finally add the water to a sufficient amount.

3. If tap water is used in the preparation of nutrient solution, tap water should be treated, because most of the tap water contains chloride and sulfide, which are harmful to plants, and some bicarbonates will also hinder the absorption of iron by roots.

Therefore, when preparing a nutrient solution using tap water, a small amount of sodium EDTA2 or humate compounds should be added to treat chlorides and sulfides in the water. If peat is used as a substrate for soilless cultivation, the above disadvantages can be eliminated. If the quality of the groundwater is poor, it can be prepared with unpolluted river water or water from Lake Kezheng.
