Half-dead flowers
When a beloved potted plant shows yellow leaves and wilts, many gardening enthusiasts often choose to discard it. Little do they know that these seemingly half-dead plants can be revitalized through simple hydroponics! This article will take the examples of longevity flowers, money trees, and bamboo plants to reveal the core techniques of reviving濒死 plants with hydroponics.
Secrets to reviving longevity flowers through hydroponics
Golden rules for root treatment
As a succulent plant, longevity flowers need to thoroughly remove decayed tissue before hydroponics. Disinfect the cutting tools with 75% alcohol, ensuring the cuts are smooth to avoid secondary infections. Retaining the main roots 3-5 cm long is more beneficial for new root growth, and the drying time for the wounds should be controlled between 4-6 hours.
Three standards for choosing containers
The milk carton hydroponic method has three advantages: shading, antibacterial, and environmentally friendly. It is recommended to use Tetra Pak boxes, as their aluminum foil layer can effectively block ultraviolet rays. The height of the container should be 1.2 times the height of the plant, with the water level controlled at 2/3 of the container, ensuring the base 3 cm is submerged.
Key points for caring for money trees in hydroponics
Importance of the disinfection process
Soaking in a 0.1% potassium permanganate solution can thoroughly kill germs, and the solution should be prepared and used immediately. After disinfection, rinse the remaining chemicals with pure water. Wrapping the base of the stem with non-woven fabric can prevent waterlogging rot.
Scientific method for water level management
Use the shallow water root-inducing method initially, maintaining the water level at around 5 cm. After the roots sprout, implement gradient water addition, raising the water level by 1 cm per week until stable. Add charcoal slices in the summer to prevent water from spoiling.
Advanced techniques for bamboo plant hydroponics
Precise control of root pruning
Retain the fleshy roots with a diameter > 2 mm and cut off all fibrous fine roots. When filling the planting basket with ceramsite, leave a 2 cm expansion space. Using the siphon water-changing method can prevent root damage.
Golden ratio for nutrient supplementation
Use AB-type hydroponic nutrient solution, diluted at a ratio of 1:2000. It is recommended to use the "three water, one fertilizer" cycle method: add nutrient solution after three water changes. Regularly adding chelated iron can prevent yellow leaves.
Through scientific hydroponic methods, not only can endangered plants be revitalized, but they can also be enjoyed throughout the year. Mastering the three core techniques of disinfection, water level control, and nutrient supplementation, even gardening beginners can easily create a hydroponic garden. It is recommended to use an EC pen to test the water quality monthly, maintaining the solution's conductivity at 800-1200 μS/cm for optimal conditions.
