Management and Maintenance of Potted Magnolia denudata in Flowering Period

Magnolia is an evergreen tree, warm and humid, not resistant to drought and cold, white as jade flowers and fragrant flowers. How to make potted Magnolia have more flowers, large flowers, colorful flowers, fragrant flowers, and long flowering period, the key is to strengthen the flowering management of potted Magnolia magnolia.

First, to pick leaves and hearts: the time to leave the room is between the Spring Equinox and Qingming Festival every year, choose cloudy or cloudy weather to go out of the room, and use 2 to 3 days after leaving the room to let the potted flowers adapt to the outdoor environment before they begin to remove the old leaves of the plant, leaving only a few tender leaves on the shoots. let it promote new shoots. Then, after each batch of flowers, a small number of old leaves should be removed to promote the growth of new branches and flower bud formation. During the growth period of Magnolia Magnolia, it is also necessary to often pick the heart, control the apical dominance and promote multiple lateral branches.

Second, it is necessary to replenish nutrients, which is an important part of flowering management. Magnolia is a fat-loving flower because it has a long flowering period and blossoms more. To this end, timely and regular replenishment of nutrients, in order to blossom, large flowers, colorful flowers, flower fragrance. In addition to applying sufficient base fertilizer in the pot, organic liquid fertilizer dominated by phosphorus and potassium should be applied every 5 to 7 days from May to October, such as rotten cake fertilizer and water. The principle of fertilization is to apply thin fertilizer frequently, and you can also take the method of lightening it first and then thickening it. Do not apply raw fertilizer, otherwise it will burn roots. At the same time, extra-root fertilization was carried out every 7 to 10 days, and leaves were sprayed with 0.5% plant oxytocin and 0.3% potassium dihydrogen phosphate.

Third, it is necessary to water magnolia at the right time. Magnolia is fleshy root, which needs water and is afraid of stagnant water. Therefore, from early summer to late autumn, water should be watered once a day to keep the soil moist, but in hot dog days, water should be watered once in the morning and evening, and water should be sprayed on the leaves and flowerpots to increase air humidity. Using tap water to water magnolia flowers, we should pay attention to prevent soil alkalinization, such as yellow leaves should be applied ferrous sulfate or 0.7% to 0.8% acid vinegar water to water roots. Leaves can also be sprayed with 0.3% to 0.4% acid and vinegar, and the effect is also very good. Do not accumulate water in the flowerpot in the rainy spring season, otherwise the roots will rot.

Fourth, the light is suitable for Magnolia magnolia is a positive flower, it needs plenty of sunlight, and it should be maintained on the balcony or sunny ground during the growth period, especially during flowering. The light should not be less than 6 hours a day. If the Magnolia magnolia is preserved in a shaded place, it will only grow leaves but not blossom, or blossom very little, slender branches, light leaves, thin leaves, no luster, which is very disadvantageous to its growth. But in the hot dog days to moderate shade, generally 12:00 to 16:00 every day to avoid scorching sun exposure, but also to avoid brick walls or cement floor high-temperature radiation. At this time, it is not only necessary to spray water to the plant to cool down, but also to water or spray water to the ground to cool and dissipate heat, increase air humidity and artificially create a suitable environment.

Fifth, it is necessary to control diseases and pests. In the process of management, attention should be paid to the prevention and control of anthracnose as well as chlorosis and root rot. If the disease is found, the diseased leaves should be removed in time, and 50% carbendazim 500x to 800x aqueous solution should be sprayed to the leaves, or 70% topiramate 800x to 1000 times solution should be used for control. Magnolia magnolia is mainly damaged by aphids and shell insects. Aphids harm buds and buds, can be used to kill, can also use 500 times the solution of washing powder spray, you can also use cotton swabs with washing powder solution to remove pests, and then spray the branches and leaves with clean water. Scale insects can be sprayed with 0.3% to 0.4% vinegar, or they can be killed by hand.
