After placing lilies in a vase, in order to maintain their freshness and beauty for a long time, the following measures can be taken: 1. Pre treatment and pruning
1. Deep Water Awakening Flowers: Cut the roots of the flowers diagonally at a 45 ° angle. The leaves do not need to be picked yet, but the flower heads cannot be soaked in water. Keeping flowers awake in water for 3-5 hours, or even overnight, can help restore their vitality.
2. Remove excess leaves: After waking up, remove excess leaves and only keep 4-6 leaves on the flower head to reduce the risk of decay and maintain aesthetics.
3. Stamen treatment: To avoid pollen scattering, the stamens can be removed, which also helps to extend the flowering period. 2、 Water quality and water replacement
1. Water quality selection: It is best to use purified water to cultivate lilies and avoid using freshly connected tap water, as the chlorine gas in tap water may cause damage to the flowers.
2. Regularly changing water: Maintaining clean water quality is an important factor in extending the flowering period. It is recommended to change the water every 2-3 days in summer and clean the vase. The water change time can be extended appropriately in other seasons, but it should not be too long in winter. Every time you change the water, check and cut off the rotten roots to keep the suction surface fresh. 3、 Increase nutrients
1. Adding nutrients: Adding some plant growth promoting nutrients such as aspirin, vitamin C, vitamin B, or glucose to water can prolong the flowering period of lilies. These nutrients do not need to be purchased specifically, just regular medications at home are sufficient.
2. Use preservatives: If conditions permit, a small amount of fresh flower preservatives can be added to water to extend the shelf life of lilies. 4、 Control the environment
1. Temperature and humidity: Lily flowers prefer a cool and shaded environment, avoiding direct sunlight or placing them in air conditioning vents. Controlling the indoor temperature between 20 ℃ and 25 ℃ and keeping the humidity at an appropriate level can help prolong the flowering period.
2. Ventilation: Maintaining good indoor ventilation can reduce bacterial growth and help maintain the freshness of lilies. 5、 Other techniques
1. Hot water treatment: Soak the tail end of the lily stem in hot water for 10 seconds (be careful not to burn the stem for too long), and then put it in water. This method can also help prolong the flowering period.
2. Reduce touch: Try to minimize touch and movement on lilies to avoid damaging flowers and branches, and affecting flowering period.
By pre-treatment and pruning, maintaining water quality and regularly changing water, increasing nutrients, controlling the environment, and using other techniques, the shelf life of lilies after vase placement can be effectively extended.
