How to promote seed setting of Asparagus

Generally speaking, a large asparagus that has grown for more than 3 years can bear seeds. If this kind of asparagus that could have borne seeds does not bear seeds at that time, the following points should be paid attention to in its management after flowering:

Use basin: if you want to make potted asparagus strong, you should use a large basin to expand the nutritional area, which is conducive to the healthy growth of asparagus. At the same time, set up a support to prevent asparagus from falling down

Fertilizer and water management: Asparagus should be fertilized timely in spring and prevented from heatstroke. After flowering, water and fertilizer should be properly controlled, and ventilation, rain and dust prevention should be strengthened to prevent falling flowers. Too much water and fertilizer in young fruit stage is also easy to drop fruit. After the fruit grows, strengthen fertilizer and water management. Watering should be moderate, not too much or too little, so as to prevent its root system from being damaged. Liquid fertilizer can be used for topdressing, but the concentration should not be too large and the interval should not be too long

Temperature and light: it is best to make asparagus accept scattered sunlight. If asparagus is exposed to the hot sun, it is very harmful to its seed setting. The temperature should be kept at about 20 ℃. If it does not meet the requirements, try to adjust it. In winter, if the room temperature is kept at 18 ℃ and more sunlight is given, more seeds can be received

Ventilation: there is always a breeze in the cultivation environment, which can strengthen the assimilation of asparagus, otherwise it is not conducive to the seed setting of asparagus. The air humidity should be increased, and water can be sprayed around the asparagus cultivation place as appropriate
