How to fertilize hydroponic flowers
Today's plant experience brings you a little knowledge about hydroponic flowers, how to fertilize hydroponic flowers. Let's introduce it to everyone by the editor.
1. Fertilizer selection
Hydroponic flowers require the application of special nutrient solutions, generally not suitable for self-preparation. Soilless cultivation nutrient solutions are formulated based on the nutrient ratio, concentration, and acidity required by flowers, containing not only the macroelements needed by plants but also other trace elements. When using nutrient solutions, strictly follow the instructions, control the fertilization concentration, and never apply blindly to avoid fertilizer damage. The purchased nutrient solutions should be stored in a dark and low-temperature place, and never use metal containers. Different flowers also have different requirements for fertilizer nutrient elements. Generally, foliage plants should mainly use nitrogen fertilizers, supplemented by phosphorus and potassium fertilizers; flowering plants, especially during their bud differentiation and bud development stages, should mainly use phosphorus and potassium fertilizers, supplemented by nitrogen fertilizers.
2. Fertilization time
Hydroponic flowers should be fertilized in the spring and autumn when they are growing vigorously, and it is generally not suitable to do so in winter and summer. If flowers show signs of malnutrition and affect growth in summer, you can spray 0.1% urea solution on the leaves.
3. Fertilization concentration
Strictly control the concentration of fertilization because all the applied nutrient elements dissolve in water. When the concentration reaches a certain level, it will cause fertilizer damage to the flowers, affecting their growth, and may even lead to the death of the entire plant.
① Different flowers require different fertilization concentrations. Flowers like Monstera deliciosa, Mini Monstera, and Ruby Philodendron are more tolerant to fertilizers and can be fertilized more densely; delicate-rooted flowers like Sisyrinchium, Oxalis, Begonia, and Coleus are less tolerant and should be fertilized lightly.
② The concentration of hydroponic flower fertilization should also be determined based on the plant's growth strength. Generally speaking, plants with strong growth are more tolerant to fertilizers and can be fertilized more densely, while the opposite should be fertilized lightly. When indoor hydroponic flowers are malnourished, fertilization should be stopped or the concentration reduced to avoid fertilizer damage.
4. Handling fertilizer damage
If the branches and leaves of the flowers show weakness and lack of vitality after fertilization, the leaves lose their luster, and the roots rot and emit a bad smell, these are signs of fertilizer damage. Once this happens, promptly cut off the rotten roots, change to clean water, and place the plant in a dark place for maintenance, changing the water once a day and checking the roots of the flowers, cutting off the rotten roots until new roots sprout, and then returning to normal maintenance.
The above sharing of how to fertilize hydroponic flowers is for reference by green plant enthusiasts, hoping to solve your problems in green plant and flower management.
