How to fertilize hydroponic flowers? Master these key points
Hydroponic flowers are relatively clean and hygienic, so many people like them. Today, the editor will share with everyone
1. Choosing fertilizer for hydroponic flowers
Hydroponic flowers need a dedicated nutrient solution, and it is generally not advisable to mix it yourself. Soilless cultivation nutrient solutions are formulated according to the proportions, concentrations, and acidity of the nutrients flowers need. In addition to the macronutrients plants require, they also contain other trace elements. When using the nutrient solution, you should strictly follow the instructions, control the fertilization concentration, and never apply it blindly, so as to avoid fertilizer burn. The purchased nutrient solution should be placed in a dark place at low temperature, and never stored in metal containers. Different flowers also have different requirements for fertilizer nutrients. Generally, foliage plants should be mainly given nitrogen fertilizer, supplemented with phosphorus and potassium fertilizer; flowering plants, especially during the stages of flower bud differentiation and flower bud development, should be mainly given phosphorus and potassium fertilizer, supplemented with nitrogen fertilizer.
2. Timing of fertilizing hydroponic flowers
Hydroponic flowers should be fertilized in spring and autumn, when growth is vigorous; generally, it is not advisable in winter and summer. If flowers show nutrient deficiency in summer and their growth is affected, a 0.1% urea solution can be sprayed on the leaves.
3. Fertilization concentration for hydroponic flowers
When fertilizing, strictly control the concentration of the fertilizer, because all the nutrient elements applied are dissolved in the water. When the concentration reaches a certain level, it will cause fertilizer burn to the flowers, thereby affecting their growth and even causing the entire plant to die. ① The fertilization concentration differs for different flowers. Flowers such as arrowhead plant, mini monstera, and red emerald philodendron are relatively tolerant of fertilizer, so fertilization can be stronger; flowers with fine roots, such as Sihai Bo, spiderwort species, begonia species, and coleus, have poorer fertilizer tolerance, so fertilization should be lighter. ② For hydroponic flowers, the concentration applied should also be determined according to the strength of the plant's growth vigor. Generally speaking, plants with strong growth vigor have greater fertilizer tolerance, so fertilization can be relatively stronger; conversely, it should be lighter. When indoor hydroponic flowers are nutrient deficient, fertilization should be stopped or the fertilization concentration reduced to avoid fertilizer burn.
4. Handling fertilizer burn in hydroponic flowers
If after fertilizing the flower's branches and leaves appear weak and listless, the leaf surface loses its luster, and the roots rot and smell bad, these are signs that fertilizer burn has occurred. Once the above situation appears, promptly cut off the rotten roots, replace with clean water, and place it in a dark place for care, changing the water once a day, and check the flower's roots and promptly cut off the rotten roots until new roots sprout again, then return to normal care.
That is all for sharing the key points of fertilizing hydroponic flowers. I hope this article is helpful to everyone, and I wish everyone good luck.
