What can be added to water for浇灌 gardenias
Gardenias, as typical acid-loving plants, watering strategies directly affect the quality of their blooming. Mastering the correct nutrient solution mixing and watering methods can make gardenia leaves glossy and increase the number of flowers. This article systematically analyzes four homemade acidic nutrient solution formulas and scientific watering techniques.
Gardenia nutrient solution mixing plan
1. Beer fermentation nutrient solution
Beer containing maltose and amino acids needs to be diluted 50 times before use, and watering once a month can promote the germination of new buds. Special note: Beer that has been opened for more than three days needs to be boiled to remove alcohol before use to avoid burning the roots. Key points: 500ml of beer + 25L of water, combined with 0.1% ferrous sulfate for better results.
2. White vinegar pH adjuster
Add 2ml of edible white vinegar to each liter of water to maintain the soil pH value within the ideal range of 5.0-6.5. Precautions: Industrial vinegar containing sodium ions should be prohibited, and it is recommended to use pH test strips to check the soil acidity and alkalinity monthly.
3. Rice washing fermentation technique
Seal the first rinse of rice water and ferment for 15 days, then dilute it at a ratio of 1:3 for use. The fermentation process produces a large number of probiotics, which can decompose phosphorus and potassium elements. Advanced technique: Adding orange peel can accelerate fermentation and eliminate odors.
4. Fruit peel active extraction liquid
Chop apple or pineapple peels and soak them for 24 hours; the filtered liquid contains natural fruit acids. It can quickly improve soil compaction in emergency use but needs to be combined with organic fertilizers to supplement long-term nutrition.
Guidelines for implementing scientific watering
Three essential reasons for thorough watering
① Inducing roots to penetrate deeper to enhance drought resistance ② Preventing the accumulation of salt and alkali substances on the surface ③ Promoting the absorption efficiency of capillary roots. Operation standard: Slow watering three times interval method - water until the bottom of the pot渗水, then repeat after 5 minutes of standing still.
Method for checking thoroughness of watering
Bamboo stake insertion method: Insert a bamboo stake into the pot soil 2 hours after watering and observe the moisture of the bottom 2/3 section; Weight comparison method: Record the weight difference before and after watering reaching 15%-20% as qualified.
By scientifically proportioning nutrient solutions and standardizing the watering process, the success rate of gardenia care can be increased by 80% or more. It is recommended to rotate different nutrient solutions monthly, combine with loosening the soil to maintain soil aeration, allowing gardenias to continuously bloom with fragrant white flowers.
