After entering the summer, it can be moved to the shade or under the awning with 40% to 50% shade, and the growth is ideal. If the light is too strong, it is easy to cause the leaves to turn yellow and lose their ornamental value, especially for potted plants that have been placed indoors for a long time. They must be careful when they are moved outdoors for restorative maintenance in summer. They should be kept in 40% to 50% shading environment first, and they should not be rushed, otherwise it will easily cause blade burns. In addition, in the late spring and early summer, in case of sunny weather after a long rain in Chu Qing, we should also do a good job of shading in time, otherwise it will also cause burns to the leaves, and it will be difficult to restore their green and lush spirit in a short time. Pay attention to this by the way.
The basin soil should always be moist, but there should be no accumulated water, and the relative humidity of the environment should be kept above 80%. In hot summer or dry autumn air period, including indoor period in winter, we should often spray water on leaves and surrounding environment to create a relatively humid local space and small environment for them and promote their vigorous growth. Water should be controlled after autumn, and more water should be sprayed and less water should be watered in winter. If there is water in the basin soil, it will easily lead to yellowing of plants, and the lower leaves will fall off after yellowing, which will seriously lead to rot and death of plant roots.
It is advisable to use fertile acidic culture soil or humus soil with loose permeability, smooth drainage and rich organic matter. Potted soil hardening or pH value higher than 7.5 will also cause yellowing of plant leaves, serious poor growth, decreased germination ability, affecting bud regeneration and even shortening its cultivation life. Therefore, small plants should change pots once a year, big plants can change soil once every two years, and loosen soil once a month during the growing season. Especially after the heavy rain, it is necessary to check the flowerpots in time. When water is found in the pots, it should be dumped as soon as possible and the loose soil should be replaced. For potted plants, it is best to arrange the time to turn over the pots and change the soil every year after leaving the house in spring to before germination.
The amount of fertilizer needed for Christmas trees is also very large. Potted cinnamon in Lan Yu requires fertile soil, and pancake fat water or fat alum water can be applied once a month from mid-spring to early autumn. After autumn, phosphorus and potassium fertilizer should be applied twice continuously, such as 0.3% potassium dihydrogen phosphate solution, to increase the cold resistance of plants, promote the early lignification of shoots and overwinter safely. In winter, all forms of topdressing should be stopped, so as not to damage the roots and cause the leaves to yellow or wither, otherwise it is difficult to restore the original appearance of plants.
