Overwatering: Overwatering can lead to waterlogging of the roots of green plants, resulting in yellow leaves. At this time, it is necessary to loosen the soil for it, and put it in a well-ventilated place for cleaning. Lack of light: lack of light for a long time of green leaves are also easy to yellow. At this time, it can be moved to a sunny place outdoors and maintained for a period of time. Fertilization is too little: If not fertilized for a long time, green plants can not get the required nutrition, but also prone to yellow leaves. At this time, it needs to be fertilized to provide nutrients.

1. Soil Requirements

It is tolerant of poor soil and does not require much soil.However, it is recommended to use loose, fertile and permeable soil for cultivation, so that the later growth will be better.The potted plant management may use the river sand, the garden soil and the peat soil mix preparation.For ground planting, turn the soil deeply first, and then sprinkle a small amount of fertilizer on it.

2. Seed and Seedling Selection

If you are sowing, you should choose seeds with full grains, so that the rate of emergence in the later period will be higher.If you plant seedlings, you should buy robust ones that are free from pests and diseases.The root system should be more complete, so that the seedlings can recover faster after planting, and the management is also very convenient.

3. Planting in the Soil

To sow, prepare the soil and sprinkle the seeds directly on it.Try to spread the seeds evenly.After sprinkling, we should water and moisten it, and control the temperature and moisture, so that it will sprout and grow seedlings in about 10 days.If planting seedlings, let its root system stretch out, fill the soil gently compacted, and then irrigate thoroughly.Don't be anxious to bask in the sun, keep ventilation first, and then manage normally after resuming growth.

4. Later Management

In the seedling growth stage, the amount of water is not much, and it is drought-resistant, so it is necessary to pay attention not to frequent water supply to avoid water accumulation.More ventilation, more sunshine, such an environment can be vigorous growth of seedlings.In addition, pay attention to the seedling stage without fertilization, avoid root burning.
