Yes, when the leaves are too large, or when the leaves of plants are yellow and dry, they should be trimmed in time, because especially hydroponics will consume the nutrients contained in the plants themselves;

Therefore, timely pruning can prevent the waste of nutrients, which will not only make plants more ornamental, but also be more conducive to the health of plants. Disinfect the trimmed tools well. And the blades are wiped to remove dust.

Before pruning, you can tie the leaves together with rope or cloth, then trim them with sharp scissors, preferably flat, and then cut the edges as short as possible.

During the period of narcissus hydroponics, it is especially necessary to give enough light, and put it in a sunny place during the day and under the light at night. This can prevent the stems and leaves of narcissus from growing white, and make narcissus leaves short, wide and strong, with dark green leaves and fragrant flowers.

Hydroponic narcissus does not need fertilization. If conditions permit, a little quick-acting phosphate fertilizer can be applied at the flowering stage to make bloom better. In order to make narcissus grow strong, it should be taken to the balcony to bask in the sun during the day.

If you want to postpone the flowering period, you can take the method of lowering the water temperature, or take the method of pouring water in the basin at night and adding fresh water the next morning. In addition, if you can't see the full flower buds before the festival 10, you can use water heating to promote the flowers, and the water temperature should be close to the body temperature.
