Can northern orchids spend the summer in the shade of trees?

When the temperature is high in summer, it is no problem to put orchids in the shade of big trees to spend the summer, and I think it is a good way to spend the summer, which is better than indoor shade and outdoor shading net. Once upon a time, I knew an orchid friend. There was a vine in the yard. In summer, orchids were placed under the grape shed and raised very well. However, if you put orchids in the shade in summer, you should pay attention to the following problems, otherwise there will still be difficulties in summer.

1. The tree should be big enough

Trees that shield orchids from the sun should be big enough, with luxuriant branches and leaves, and should be shady after 10: 00 a.m. to 6: 00 p.m., with a shading rate of more than 70% at noon. Instead of just covering up for a while at noon, the orchids still have the possibility of sunburn and sunburn. In particular, the ground hardened with brick or cement, the tree is relatively small, high-temperature weather orchids are not suitable to be placed in the shade of such trees.

2. it is necessary to do a good job in preventing rain.

Orchids grow in the shade in summer should pay attention to prevent continuous rain and torrential rain, easy to breed bacteria, rotten roots, yellow leaves, leaf spots and so on. If orchids are originally raised in dew, a short period of light rain can help to grow. If the orchid was originally raised indoors, now move to the outdoor, do not let direct rain in the short term, outdoor maintenance for more than 20 days, can be caught in the light rain. In case of a long period of rainy days or torrential rain, the orchids should be moved to places where there is no rain for maintenance. The same treatment is done when there is a strong wind to prevent the damage to the leaves of orchids.

3. Disease prevention should be done well.

For orchids maintained in the shade of outdoor trees, disease prevention should be done to avoid diseases in high temperature weather, because there are more kinds of outdoor bacteria, more active, and more likely to be infected. At ordinary times, we should pay attention to observe the growth and state of orchids, and find that they are not handled in time. For orchids that are not growing well, they should be treated with medicine in advance instead of waiting until they get sick.

4. Pay attention to watering

Although the light of the outdoor orchid maintained in the shade is not strong, it has the advantages of large water evaporation, good ventilation and low air humidity in high temperature weather, so we should pay attention to replenish water in time to keep the plant materials moist. And do not control the water too much, let the plant too dry, resulting in orchid lack of water and empty roots, yellow leaves, dry tips and so on. Some flower friends move orchids to outdoor maintenance, or according to the indoor watering frequency, this is wrong, outdoor maintenance and indoor maintenance plant drying speed is not the same, according to the changes of the maintenance environment to adjust the watering frequency. However, it should be noted that watering should still follow the principle of no dry and no watering. Too much watering in high temperature weather is more harmful than less watering. If the plant material is not very good, the root will rot in minutes.

5. it is better to put it in the shade of trees without hardening.

In summer, if the orchid can be placed in the shade of the ground without hardening, it will not only be easy to spend the summer, but also look healthy. Because the air humidity in the north is relatively low, the ground vapor transpiration is very weak after the ground hardening treatment, even if the orchid can spend the summer smoothly, the green and oily feeling of the leaves will be affected. If the ground is not hardened, the earth gas transpiration is strong, the orchid receives the earth atmosphere, and the air humidity of the microenvironment is improved, regardless of growth or color. Of course, this is an icing on the cake suggestion, if there is no ground without hardened shade, there is no need to force it.

Conclusion: when it is hot in summer, it is a good choice to put orchids in the shade, but pay attention to the amount of shade, shading intensity and shading area. Orchids maintained in the shade of outdoor trees should pay attention to rain protection, disease prevention, and proper watering to ensure that the roots will not be dried.
