The seasonal Management method of Magnolia

Attention should be paid to the cultivation of Cymbidium in winter

1. Fertilization. The vegetative growth rate of Magnolia in winter is the fastest and needs the most nutrients, so it is very important to apply winter fertilizer well. Before entering the room, flowerpots should be watered with bone powder, fried sesame, cooked soybeans or compound fertilizer every 15 to 20 days, and the roots can also be watered with soaking solution of animal and plant residues. It is necessary to ensure that the fertilizer is ripened and applied lightly to prevent the injury of thick fertilizer.

2. Watering. Gentleman orchid is a fleshy root, angry and afraid of water stains. In addition, the leaves of Cymbidium have waxy layer, the temperature is low in winter, and the transpiration and evaporation of water are less. Therefore, watering should not be too much, only combined with fertilization watering, to keep the basin soil moist. Must not be flooded with water, resulting in rotten roots and dead seedlings.

3. Keep warm. The most suitable temperature for the growth of Cymbidium was 15 ℃ to 25 ℃, 10 ℃ stopped growing and 0 ℃ was damaged by freezing. Therefore, it must be kept warm and frost-proof in winter. After the flower stem is extracted, it is suitable to keep it at about 18 ℃. If the temperature is too high, the leaf and flower moss are only long and thin, the flower quality is poor, and the florescence is short; the temperature is too low, the flower stem is short, it is easy to be born prematurely (flowering), which affects the quality and reduces the ornamental value.

4. Dimming. Gentleman orchid likes to scatter light and avoid direct strong light. Winter indoor maintenance, flowerpots should be placed in a place with plenty of light. Especially before flowering, there should be good light, which is beneficial to the development and firmness of flower buds. After flowering, proper cooling, avoiding strong light and keeping good ventilation are beneficial to prolong the flowering period.

5. Protecting leaves. The characteristics of healthy magnolia are as follows: the leaves are fat and strong, the leaves are colorful, the leaves are short, wide, thick, green, bright and strong, and they are the basis for promoting flowering and improving ornamental value. To maintain strong leaf quality, in addition to providing reasonable fertilizer and water, it is necessary to keep the leaf surface clean in order to improve photosynthetic efficiency.

The methods of leaf protection are as follows: one is to wash the leaves regularly and spray or wipe the dust on the leaves with the same water to keep the leaves clean; the other is to spray fungicides in time to prevent the occurrence of leaf spot, leaf blight and stem rot and ensure that the leaves are green and the flowers are beautiful.

Cymbidium is afraid of high temperature. in midsummer, the temperature is often above 30 ℃, which is extremely disadvantageous to the growth of Cymbidium. For this reason, it is commonly used to set up a shed to cool down. You can also bury the magnolia in the sand (bury the basin), and then sprinkle water on the sand every morning and evening. In this way, not only the basin soil can be kept moist, but more importantly, the heat absorption effect of water evaporation in the sand can be used to achieve the purpose of cooling. To make the magnolia safe through the hot summer.
