Although orchids are beautiful, they are not easy to raise.

There are many varieties of orchids, and it is said that there are more than 20,000 varieties! What's more, orchids bloom in a variety of colors and shapes, so orchids have been flourishing in the international flower market. Although the orchid is beautiful, it can be said to be very difficult to raise, and these key points of maintenance are not quickly written down!

1. Soil.

Orchid soil should be equipped with humus soil or rotten leaf soil, preferably slightly acidic, which is more conducive to plant growth. The root system of orchid requires high ventilation, so mixing vermiculite or perlite on the basis of humus soil increases the soil void, which is beneficial to drainage and ventilation. Humus soil: perlite: vermiculite = 7:2:1 can be used to mix soil.

two。 Water it.

Orchids like a moist conservation environment, so the soil moisture should be kept moderate, neither drought nor stagnant water. It is basically watered every 3 days in spring and autumn and almost once a day in summer. Orchids need less water in winter and can be watered every 5-7 days. Watering is not recommended to pour water on the leaves, if you want to cool it, you can sprinkle water around the flowerpot.

3. Rizhao.

Orchids are shade-loving plants and have no resistance to direct sunlight, so they should be avoided. When we say Xi Yin here, we really like Yin. Of course, in addition to summer is absolutely can not be exposed to the sun, even the spring, autumn and winter these three seasons of noon and afternoon sunshine should be avoided. It can be maintained in the corner of the table or bookcase in the study.

Of course, take it out occasionally to see the sun, but only in the soft sun in the morning or after sunset, put it on the balcony when the sun has gone down and enjoy half an hour of sunshine. A little bit of strong sunlight will burn it, especially in the flowering period, but also to avoid direct glare.

4. Fertilize.

Orchids need more nutrition to bloom well. The nutrients in humus soil can not meet the growth needs of orchids at all, so the way of base fertilizer and late topdressing can be used to supplement it. When compounding the soil, a layer of slow-release fertilizer containing more potassium can be put at the bottom, which is helpful to promote flowering.

After putting the base fertilizer, the usual concentration of topdressing must be light. During the growth period, 15% of the thin cake fertilizer water, 0.1% urea fertilizer water or 0.2% potassium dihydrogen phosphate fertilizer water can be applied, and the fertilization frequency is about once every 20 days. On this basis, the method of fertilizing leaves can also be used to supplement nutrients.

It is suitable to supplement foliar fertilizer during flowering stage and flowering period, and 0.2% potassium dihydrogen phosphate can be sprayed to the leaves for about 10 days, which is beneficial to the development of flower stems and flowers. Be careful not to spray on the buds when spraying.
