Maintenance and management of Magnolia in midsummer

Shelter from the sun in summer, you should put the gentleman orchid in a well-ventilated environment with no strong light. Gentleman orchid is a medium-light flower, suitable for the soft light of spring and autumn, not suitable for hot sun exposure. In summer, it is best to put the potted plants under the shade shed, and the sun penetrates through the cracks in the shade shed, so that the plants can receive weaker light. It is ideal to place it in a place where direct sunlight can be shielded from direct sunlight at noon and can be seen sooner or later. Generally speaking, summer shading should reach more than 60% and 70%.

Cool and humidify the magnolia in a ventilated place in summer. If the ambient temperature is above 35 ℃, the water in the soil evaporates too fast, which will make the water and nutrients of Cymbidium fall short of demand. Therefore, it is best to put the Magnolia basin on the pool or basin (with a wooden board), and often spray water around the plant and on the leaves, so as to improve the warm and humid environment of the orchid, so that it can grow in a small environment with a humidity of less than 25 ℃ and a humidity of 60% Rue 70%, in order to safely spend the summer and promote the growth of the orchid in summer.

Properly watered magnolia is native to the primeval forest of South Africa, which makes it special in morphology and physiological function. Cymbidium has broad leaves and tender texture, which requires high soil water content and high air humidity. In the hot summer, the orchid grows slowly, the root system absorbs less water, but the foliar water evaporation is very large. Therefore, the gentleman orchid can not lack of water, otherwise the fleshy root shrinks, the leaf shape is thin and dull. When watering, we should adhere to the principle of watering half dry and watering thoroughly. But you can't water the topsoil as soon as it's dry. Otherwise, the potted soil is in a moist state for a long time, and it is easy to rot roots and yellow leaves. When watering, you must be careful not to let the water flow into the heart of the leaves, so as not to cause rotten heart disease and lead to "beheading".

The temperature of controlled fertilization is high in summer, and the orchid is in a semi-dormant or dormant state, so it is necessary to control fertilization with little or no application as far as possible. Because its root absorptive capacity is weak in this period, if fertilizing or fertilizing a little more, fertilizer accumulates around the root system for a long time, which is easy to cause rotting root and rotting stem. But during this period, if the temperature of the growing environment of Cymbidium is below 25 ℃, some dilute liquid fertilizer can be applied properly to promote its growth and shorten its dormancy period; if the temperature drops below 20 ℃ and the humidity meets the requirements, fertilizer can be applied as usual.
