Key points of maintenance of potted evergreen
1. Summer
It grows vigorously in summer, so it needs to be placed in a cool place to avoid strong light, otherwise it will easily cause dry and sharp leaves and affect the ornamental effect. Evergreen is a fleshy root system, which is most afraid of waterlogging. So you can't water more, otherwise it will easily cause rotten roots.
Pot soil can be watered with appropriate amount of water at ordinary times. Dry soil is better than wet soil. In addition to keeping the soil moist in summer, watering should not be too frequent in spring and autumn. Sprinkle water on the ground around the flowerpot every morning and evening in summer to create a humid microclimate. Attention should also be paid to prevent heavy rain from pouring down.
In the growing period, the decomposed liquid fertilizer is applied once every 20 days or so; It grows vigorously in early summer, and liquid fertilizer can be applied once every 10 day, and a small amount of 0.5% ammonium sulfate can be added when topdressing, which can promote its growth and make its leaves dark green and bright. When flowers are in full bloom from June to July, 0.2% dihydrogen phosphate solution should be applied every 15 days to promote flower bud differentiation and facilitate better flowering and fruiting. Don't get wet in the rain during flowering, and put it in a dry, cool and ventilated place.
2. Winter
Evergreen should be moved indoors for the winter, and placed in a sunny and well-ventilated place, and the temperature should be kept at 6- 18 degrees. If the room temperature is too high, it is easy to cause the leaves to grow white and consume a lot of nutrients, resulting in weak growth in the second year and affecting normal flowering and fruiting.
In winter, if the evergreen leaves turn yellow or even the whole plant withers, it is mainly because the roots can't absorb water, which affects the growth. Therefore, in winter, the air should be kept moist, and the basin soil should be slightly moist. Generally, it is advisable to water it 1-2 times a week. In addition, it is necessary to spray and wash the leaves with warm water once a week to prevent the leaves from being polluted by smoke and dust, so that the stems and leaves remain light green all the year round.
