When to Plant Yulan Magnolia

The plots with sufficient light, soft and good drainage capacity shall be selected. We can dig a big hole first, then put organic fertilizer into it, then put it into the saplings with the soil mass, and then fill and compact it.

Yulan Magnolia Care in Detail

Yulan Magnolia Watering

How many days does yulan magnolia water in spring? Under normal circumstances, it only needs to be watered once in 2-3 days in spring. You can't water too much. You can see that the soil is completely wet, and you must not accumulate water.
High temperature and fast evaporation in summer are also the peak growing season of yulan magnolia. The watering frequency should be improved. How can to water Yulan Magnolia in summer? During the period from summer to late autumn, water it once a day, and keep the basin soil moist. When the temperature rises to more than 30 degrees, we often spray water on the leaf surface to cool down.
The temperature will slowly decrease in autumn, and the water required by the plant will also slowly decrease. How many days does yulan magnolia water in autumn? In autumn, it is generally enough to water once a week. However, autumn is relatively dry. If you see that the basin soil is too dry, pour a little more. Do not water too much to avoid ponding.
Although yulan magnolia is cold-resistant, it will grow slowly in winter. At this time, it does not need too much water, but it cannot be watered. So how to water Magnolia in winter? In winter, water the basin soil after it is completely dry. The watering time is not fixed, but it can be watered once in 20-30 days.

Yulan Magnolia Soil

Yulan magnolia is suitable for growing in slightly acidic soil, preferably deep soil. When we prepare soil for it, it is better to be rich in humus, which can be fully mixed with garden soil, rotten leaf soil, coarse sand and fully decomposed base fertilizer. Such soil has good drainage, and sufficient rotten leaf soil can supplement nutrients required for plant growth and make yulan magnolia grow better.

Yulan Magnolia Light

Yulan magnolia flower blooms for a long time and you can enjoy Yulan Magnolia bird-shaped flowers sometimes! Generally, it needs enough sunshine during the flowering period. With the help of sunshine, yulan magnolia can open more flowers. If yulan magnolia lacks light during the flowering period, its flowering period will end ahead of schedule, but we need to take sunscreen measures at high temperatures.

Yulan Magnolia Temperature

Yulan Magnolia has strong cold resistance. Generally, it has no problem in the environment of minus 5-6 ℃, and can endure the low temperature of minus 20 ℃ in the short term. Yulan Magnolia is a deciduous tree with a height of up to 25m. Its bark will be grayish-brown and its leaves are paper, mostly obovate.

Yulan Magnolia Humidity

Yulan magnolia wants to drill into the water to cool herself in hot summer. But it's not that we put yulan magnolia in the water, but that we should create a humid environment. What should we do? Diligent little friends can spray some water on the leaves of magnolia to maintain humidity. As for the watering of yulan magnolia, the principle of seeing dry and seeing wet will be adopted here. If the soil is too dry, it will harden and dry and inhibit the growth of roots. Too wet is easy to cause root rot, so this method is applicable not only to Yulan Magnolia, but also to most plants.

Yulan Magnolia Fertilizer

Before we propagate Yulan magnolia tree, in order to grow more vigorously after plant colonization, we'd better apply sufficient base fertilizer to the plant. At this time, we can select some livestock manure as base fertilizer or other organic fertilizer.
When the new buds of the plant develop, we'd better select some mature cake fertilizer for it, because the mature fertilizer is more vigorous for the growth of the plant, so as to maintain the plant more robust.
For the growth period of yulan magnolia, the demand for nutrients is very high. Therefore, during the growth period of Magnolia, we'd better apply some nitrogen, phosphorus and potassium fertilizer or common organic compound fertilizer every 15-20 days.

Yulan Magnolia Pruning

Yulan magnolia pruning is generally not used because it has few branches, but it is not reserved for ornamental purposes. We can cut off the flower stalk after the flower withers to avoid wasting nutrients in the body. In addition, when the tree is aging and flowering is rare, pruning can be used for rejuvenation. The specific method is to cut the poorly growing branches from the base when the leaves are just growing, and then open a circle of ditch on the ground at an equal distance from the periphery of the tree crown, so as to facilitate fertilization and watering and promote the development of new branches. If there are too many new branches, yulan magnolia pruning can be carried out for plastic pruning, and they can be kept preferentially for about 2 ~ 3 years before they can bloom normally. The wound healing ability of yulan magnolia branches is poor, and it is generally appropriate to trim less or not. However, in order to cultivate a reasonable tree shape, we should pay attention to the reasonable layout of trunk and main branches at the seedling stage. For large trees, sparse cutting of long branches, dry branches, disease and insect branches, inward branches and Cross branches can concentrate nutrients and promote more flowering and large flowers. Yulan magnolia pruning should cut off the remaining flowers after the flowers wither and before spreading the leaves. If there is no seed left, the remaining flowers should be cut off.

Yulan Magnolia Repotting

Yulan magnolia repotting should be carried out once every 1 ~ 2 years for small potted plants, and 3 ~ 4 years for large potted plants. Do not turn the pots and change the soil every time in cloudy and rainy days, but in the autumn sun, so that the roots of the plants can quickly adapt to the pot soil and make the white orchids grow better.
Every time yulan magnolia repotting, we first need to select mud tile pots, ceramic pots, etc. according to the plant size. As long as there are containers with drainage holes at the bottom, we also need to mix black soil, pastoral soil and river sand in the ratio of 2:2:1 as basin soil, and nitrogen phosphorus compound fertilizer can be used as base fertilizer.
Generally speaking, when talking about how to carry out yulan magnolia repotting, we can first stop watering and fertilizing the white orchids a week ago, or water a lot around the basin soil the day before yulan magnolia repotting, so that it is easier to take the plants out of the old basin and avoid accidental injury to the roots of the plants. We can treat the rotten roots and put them in the shade for three days.

Yulan Magnolia Pest & Disease Control

Anthrax: This yulan magnolia pest disease causes spots on the leaves of plants. In severe cases, it will lead to leaf abscission and even plant death. After the onset of the disease, we should first cut off the diseased leaves, and then spray it with mancozeb solution for treatment. Root rot: it will cause root rot of diseased plants. After the disease, the diseased plants shall be removed from the basin, trimmed and disinfected and replanted. Insect pests will also affect the growth of yulan magnolia, which will bite the plant and hinder its growth. After birth, the wormhole should be blocked with cotton dipped in dichlorvos liquid.
