How to fertilize hydroponic flowers? Fertilization techniques for hydroponic flowers

Hydroponic flowers are a cultivation method chosen by many friends, so how are hydroponic flowers fertilized? Below is an introduction to the fertilization techniques for hydroponic flowers.

1. Choice of fertilizer

Hydroponic flowers need a dedicated nutrient solution, and it is generally not advisable to mix your own. Soilless cultivation nutrient solutions are formulated according to the proportions, concentrations and acidity of the nutrients the flowers need; besides the major elements plants require, they also contain other trace elements. When using a nutrient solution, you should strictly follow the instructions, control the fertilization concentration, and never apply it blindly, so as to avoid fertilizer burn. Purchased nutrient solutions should be stored in a dark place at low temperature, and metal containers must never be used for storage. Different flowers have different requirements for fertilizer nutrient elements. Generally, foliage plants should be given mainly nitrogen fertilizer, supplemented with phosphorus and potassium fertilizer; flowering plants, especially during their flower bud differentiation and flower bud development stages, should be given mainly phosphorus and potassium fertilizer, supplemented with nitrogen fertilizer.

2. Fertilization time

Hydroponic flowers should be fertilized in the vigorous growing seasons of spring and autumn, and generally should not be fertilized in winter and summer. If flowers show nutrient deficiency in summer that affects their growth, a 0.1% urea solution can be sprayed on the leaves.

3. Fertilization concentration

Strictly control the fertilization concentration when fertilizing, 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 leading to the death of the entire plant. (1) Different flowers require different fertilization concentrations. Flowers such as arrowhead plant, mini monstera, and red emerald philodendron are relatively tolerant of fertilizer and can be fertilized more heavily; flowers with fine roots, such as Sihai Bo, spiderwort species, begonia species, and coleus, have poor fertilizer tolerance and should be fertilized more lightly. (2) For hydroponic flowers, the concentration applied should also be determined by the strength of the plant's growth vigor. Generally speaking, plants with strong growth vigor have greater fertilizer tolerance and can be fertilized relatively more heavily; conversely, they should be fertilized more lightly. When indoor hydroponic flowers are suffering from nutrient deficiency, fertilization should be stopped or the fertilization concentration reduced, so as 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 roots rot and smell foul, these are signs that fertilizer burn has occurred. Once the above situation appears, the rotten roots should be cut off in time, the water replaced with clean water, and the plant kept in a dark place for care, changing the water once a day and checking the flowers' roots, cutting off rotten roots promptly, until new roots sprout again, after which normal care can be resumed.
