Fertilizing Hydroponic Flowers: Pay Attention to Fertilizer Concentration
Many friends think that hydroponic plants do not need fertilizing, but this view is actually wrong. Hydroponic flowers also have special nutrient solutions, but when fertilizing different flowers, you should also pay attention to controlling the concentration of the nutrient solution, so that hydroponic flowers can grow healthily.
Monstera deliciosa (details)
When fertilizing, strictly control the concentration of the fertilizer, because all the nutrient elements applied are dissolved in 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 fertilizer concentration differs for different flowers. Flowers such as Syngonium podosum (details), mini Monstera deliciosa, and Philodendron erubescens 'Red Emerald' are relatively tolerant of fertilizer, so they can be fertilized more heavily; flowers with fine roots, such as Achimenes, Commelinaceae, Begoniaceae, and Coleus (details), have poorer fertilizer tolerance, so they should be fertilized more lightly.
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 they can be fertilized relatively heavily; conversely, they should be fertilized lightly. When indoor hydroponic flowers suffer from nutrient deficiency, fertilizing should be stopped or the fertilizer concentration should be reduced to avoid fertilizer burn.
Hydroponic Flowers: Key Points of Fertilization Techniques
1. Choice of fertilizer
Hydroponic flowers need a special nutrient solution, and it is generally not advisable to mix your own. Soilless cultivation nutrient solutions are formulated according to the proportions, concentration, and acidity of the nutrients required by the flowers. In addition to containing the major elements needed by plants, they also contain other trace elements. When using the nutrient solution, you should strictly follow the instructions and grasp the fertilization concentration. Do not apply blindly, so as to avoid fertilizer burn. Purchased nutrient solutions should be placed in a dark, low-temperature place, and never stored in metal containers. Different flowers also have different requirements for fertilizer nutrient elements. Generally, foliage plants should be mainly given nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers; flowering plants, especially during their flower bud differentiation and flower bud development stages, should be mainly given phosphorus and potassium fertilizers, supplemented by nitrogen fertilizer.
2. Fertilization time
Hydroponic flowers should be fertilized in spring and autumn, when growth is vigorous; it is generally not advisable in winter and summer. If flowers show nutrient deficiency in summer that affects growth, a 0.1% urea solution can be sprayed on the leaves.
3. Fertilization concentration
When fertilizing, strictly control the concentration of the fertilizer, because all the nutrient elements applied are dissolved in 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 fertilizer concentration differs for different flowers. Flowers such as Syngonium podosum, mini Monstera deliciosa, and Philodendron erubescens 'Red Emerald' are relatively tolerant of fertilizer, so they can be fertilized more heavily; flowers with fine roots, such as Achimenes, Commelinaceae, Begoniaceae, and Coleus, have poorer fertilizer tolerance, so they should be fertilized more lightly. 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 they can be fertilized relatively heavily; conversely, they should be fertilized lightly. When indoor hydroponic flowers suffer from nutrient deficiency, fertilizing should be stopped or the fertilizer concentration should be reduced to avoid fertilizer burn.
4. Dealing with fertilizer burn
If after fertilizing the flowers' branches and leaves appear weak and listless, the leaf surface loses its luster, and the root system rots and smells bad, these are signs that fertilizer burn has occurred. Once the above conditions appear, promptly cut off the rotten roots, replace with clean water, and place in a dark place for care, changing the water once a day, and check the flowers' roots, promptly cutting off rotten roots, until new roots sprout again, then return to normal care.
