How to water triangular plum (how often) how do the leaves of triangular plum turn yellow?

When it comes to triangular plum, I believe everyone is very familiar with it, because triangular plum belongs to a relatively common flower plant in our life, its flowers are colorful, the leaves are green, and it has high ornamental value. So do you know the watering skills of triangular plum? Let's learn about the maintenance skills of triangulated plum with the editor.

How to water triangular plum (how often)

Triangular plum has a lot of leaves, and the leaves are also very large, so the water of triangular plum is easy to consume and has a large amount of water evaporation, especially in summer. Therefore, appropriate watering measures should be taken.

First of all, the amount of water should be increased during the growth period in early summer, which can promote the growth of branches and leaves. After the growing period, the amount of water should be reduced at the end of summer, generally 3 or 4 times, which can accelerate its germination and growth.

Secondly, when the flower buds grow after the triangle plum sprouts, it is necessary to increase the amount of water again to promote flowering.

Finally, after October in early winter, because of the decrease in temperature, the amount of water should also be reduced, once every three days, with the continuous drop in temperature, if the soil is not dry, do not water. Or wait until the soil is dry before watering.

The water control of triangular plum lasts for about three weeks, which is carried out before flowering, and the water control must be completed, watering half less than usual, or only spraying. Do not water when it is rainy, increase the amount of water appropriately in hot weather, and do not apply fertilizer during the water control period.

What if the leaves of Prunus mume turn yellow?

1. Improper watering

The water demand of triangular plum is different from season to season, and it is easy to cause yellow leaves if it is not watered properly. Triangular plum is watered once a day in spring and autumn and once in the morning and evening in summer. The temperature is lower in winter and the first half of the plant is dormant, so watering should be reduced and the basin soil should be kept slightly wet.

2. Improper lighting

The seedlings that are fresh all the year round should be placed in the semi-shade first. Winter should be placed in front of the southward window, and the lighting time should not be less than 8 hours, otherwise a large number of fallen leaves are easy to appear.

3. Improper selection of soil (stagnant water)

Triangle plum is not strict on soil, but it is afraid of stagnant water and is not resistant to waterlogging. therefore, loose and well-drained culture soil must be selected. generally, 4 parts of humus soil, 4 parts of garden soil and 2 parts of sand can be selected. Sun-dried pond mud mixed with some coal cake residue can also be used as basin soil. In addition, when changing the basin every year, half of the old soil needs to be replaced and added to the new soil to ensure sufficient nutrients in the soil.

4. Improper fertilization

Triangular plum often causes yellow leaves due to improper fertilization. In hot summer or cold winter, triangular plum grows slowly or even dormant, so fertilizer should be stopped. Fertilization will cause fertilizer damage and cause rotten roots and leaves to turn yellow. Or the application of fertilizer or raw fertilizer will hurt the roots, lead to leaf shedding, and even plant death.

What if the leaves of Prunus mume turn black?

1. Soil knot

If the soil is not loose for a long time, it will clump, affecting the plant to absorb nutrients from the flower soil, resulting in no leaves at the bottom of the plant trunk and blackening of the leaves at the top.

Solution: you can prepare your own soil with humic substances. Crush the red soil without stones and sand, add some rotten leaves of vegetables, put them in a bag, and add some water to ferment. This kind of soil is much better than ordinary soil, because after fermentation, laterite becomes mature soil, which is not only nutritious, but also soft and breathable, making it more suitable for planting. In addition, it should be replaced with a larger basin and some fresh soil should be added without hurting the original soil ball.

2. Leaf spot

If its leaves are black, another possibility is to get sick. if you get leaf spot disease, at the beginning, the spot is brown, a halo of green and yellow will appear around it, and then it will expand into a round shape and become dark brown, and then it will become a black dot, so the leaves will turn black.

Method: if there are fewer spots, you can apply daconine cream on it and cut off the branches with more disease spots. Then use carbendazim once every 7-10 days, if it is more serious, after the first spray, spray again every four days, and then spray once a week, a total of three or four times, the effect will be very good.

How to prolong the flowering period of Prunus mume

1. Flower fertilizer: this aspect is undoubtedly very important. As we all know, flowering requires a lot of nutrients. If you want to prolong the flowering period, only the nutrients contained in the soil are not enough. At this time, we need to apply some flower fertilizer. We can choose to use some compound fertilizer, as well as calcium superphosphate. The effect of using them alternately is best. In addition, other liquid fertilizers are also available. For specific nutrient elements, more fertilizer containing P and K can be used to promote the differentiation of flower buds.

2. Light: this kind of plant likes light very much. Especially during the flowering period. Light allows the plant to accumulate some nutrients. Therefore, if we want to prolong its florescence, we must bask it in the sun more. It is best to guarantee ten to twelve hours a day. If it is not satisfied, then artificial replenishment of light can also be done. However, it should be noted that ventilation conditions must be ensured.

3. Temperature: only by adjusting this factor can we ensure that it blossoms for a long time, and we can control it at about 20 degrees. In addition, it is also related to the amount of flower fertilizer, if the temperature is high enough, so it does not matter to apply more flower fertilizer.

As mentioned above, many people like to raise gorgeous triangular plums at home to decorate the room or courtyard, but due to incorrect maintenance methods, leading to all kinds of problems, in fact, the problems are not terrible, as long as we find out the cause in time, and then prescribe the right medicine to the case, afraid of flower friends who ignore the problems.
