How many days can a sunflower be hydroponically cultivated
Below is an introduction for netizens on how many days a sunflower can be hydroponically cultivated and some knowledge on how to extend the hydroponic cultivation time of sunflowers. Please refer to the detailed introduction below.
Sunflowers have bright and lively colors and can refresh one's mood when placed in a vase at home. However, such sunflowers do not last long. Without experience, it's easy to let them wither in a vase. This article will tell you how many days a sunflower can be hydroponically cultivated and how to extend its hydroponic cultivation time!
How many days can a sunflower be hydroponically cultivated
About seven days. Hydroponic cultivation of sunflowers requires great attention to methods. Incorrect care can cause them to wilt prematurely. Hydroponic cultivation of sunflowers has strict requirements for various factors, and proper control can extend the blooming period.
How to extend the hydroponic cultivation time of sunflowers
1. Add nutrient solution: Although the method of hydroponic cultivation of sunflowers is simple, it requires more effort to keep them healthy. To cultivate sunflowers well in water, you need to add some nutrient solution to the water they grow in. Plant nutrient solutions can provide sufficient moisture for sunflowers, and regular additions can extend the blooming period.
2. Tea water care: In addition to adding nutrient solutions, tea water can also be used to extend the blooming period. Use high-concentration tea water to replace clean water for plant care. Tea water can extend the blooming time of sunflowers, but the tea water needs to be changed every day to achieve this goal.
3. Regularly change water: Hydroponic cultivation of sunflowers has high requirements for water quality. Any impurities in the water can cause the flowers to wilt. Therefore, it's necessary to change the water frequently, approximately once a day. After changing the water, add nutrient solutions and other substances, and place them in a cool and well-ventilated area to extend the blooming time.
4. Stem treatment: Cut the bottom of the stem at a 45-degree angle and trim about 2-3 centimeters. Remove the leaves from the bottom of the stem, leaving only the top leaves. Before inserting the sunflower into the water, dip the stem into hot water to slightly block the freshly cut opening, preventing the loss of nutrients from the stem and promoting later hydroponic cultivation.

5. Cut end treatment: Of course, it's not enough to just make a diagonal cut and then place it directly in the hydroponic environment. Since there is a lot of sap in the stem, after cutting, it should be soaked in hot water for a while to prevent excessive sap loss and nutrient depletion. The soaking time should not be too long, 2-3 minutes is sufficient, otherwise the roots can become soft.
6. Rootstock treatment: When hydroponically cultivating fresh sunflowers, choose healthy, disease-free, and undamaged varieties. Thick stems have strong survival capabilities but lower water absorption, so cultivators can make diagonal cuts at the bottom of the plant to increase the water absorption of sunflowers.
7. Care management: To extend the hydroponic cultivation time of sunflowers, it's essential to strengthen care management. Regularly change the water to ensure sufficient oxygen content and avoid cloudy water due to long-term non-changing. To extend the hydroponic time, you can add nutrient solutions or preservatives to provide good nutrients and extend the hydroponic time.
