Cultivation methods and matters needing attention of Dendrobium

Growth habit of Dendrobium

Dendrobium is mainly distributed in tropical and subtropical Asia and likes warmth. Humid and semi-cloudy environment, not cold-resistant. The optimum growth temperature is between18 and 30℃. Dendrobium should not be dry and afraid of water accumulation, especially when new buds begin to sprout and new roots form.

But it is too humid, and it is easy to rot when it meets low temperature. I like the light, the sunshine is abundant, the flowers bloom well in autumn, and there are many flowers.

land

Potted Dendrobium is usually mixed with coarse sediment, coal, pine bark, charcoal blocks and so on. , so that the root system can be drained, breathable and moisturized to a certain extent, which is beneficial to root system development. Let Dendrobium grow better.

illuminate

Dendrobium is a kind of tropical rain forest vegetation, so it is suitable for humid environment because it should avoid direct sunlight. You need a little shading in spring and summer, and winter is a dormant period, so you don't need shading.

temperature

Dendrobium likes high temperature environment, and the most suitable growth temperature is about 15-30℃, preferably not more than 35℃ and not less than 5℃ at the lowest.

At night, the temperature is controlled at 10 degree, and the temperature difference is controlled within 10 degree. Dendrobium is not conducive to growth and flowering in low temperature environment.

water

Dendrobium is a plant that likes a lot of water, but it is not suitable for being too wet and prone to problems such as rotten roots. Dendrobium orchids can be watered less in winter, but attention should be paid to increasing the humidity in the air.

In summer, water is usually poured once every 2-3 days, and it is poured thoroughly every time; It needs to be watered every other week in spring and autumn, and it should be watered thoroughly every time.

Change the pot

If Dendrobium is cultivated for more than 2-3 years, its plants will rot roots and pots, so it should be replaced in time.

Both evergreen and deciduous Dendrobium change pots after flowering. When changing pots, you should hurt the roots less, otherwise the leaves will turn yellow and fall off at low temperature.

Fertilize soil or land

When applying fertilizer to Dendrobium, we should pay attention to applying thin fertilizer frequently and apply fertilizer once every ten days or so. We can adjust the ratio of nitrogen, phosphorus and potassium according to the growth period, and spray it on leaves or irrigate roots. Usually do it once a week until the pseudobulb matures and enters the winter dormancy period, and then completely stop fertilization.
