Maintenance and watering skills of bonsai flowers in summer

Summer is hot and rainy, which is not only the peak season for the growth of some flowers, but also the dormant period for some flowers. In order to make flowers go through this stage smoothly, the management should be strengthened in the aspects of watering, shading, prevention and control of diseases and insect pests.

First of all, the summer temperature is high, water evaporation is fast, should be more watering every day, such as watering once in the morning and evening. At the same time, in the high temperature season, in addition to jasmine, rose and other exuberant flowers, it is generally not suitable to apply fertilizer, especially the cuckoo that enters the semi-dormant period and the dormant bulbous flowers such as cyclamen and freesia.

Secondly, for some semi-overcast and negative flowers, avoid high temperature and direct sunlight in summer. Shading measures should be taken and water should be sprayed to cool down. Even drought-tolerant plants such as cacti are at risk of being burned when the temperature exceeds 38 ℃. In addition to daily watering, cuckoos should also spray water on the leaves and the ground to keep moisture and cool down. But there are often heavy rains in summer. After the basin soil is stagnant, nutrients are easy to be lost, so the basin should be tilted to drip out of Rain Water after rain.

Finally, the muggy summer is also the season with high incidence of diseases and insect pests. It is necessary to remove the diseased branches and leaves in time, supplemented by drugs for prevention and treatment. Such as monthly and summer prone to black spot disease and powdery mildew, the former with Bordeaux liquid, the latter with carbendazim, once a semimonthly spray. Orchids are prone to anthracnose in plum rain and high temperature seasons. in addition to improving ventilation and light transmission, topiramate can be sprayed every 10 days when the disease occurs.

The respiration of potted flowers is exuberant in summer, which requires good permeability of potted soil. Therefore, the basin soil should not be watered when it is not dry, so as not to affect the air permeability, but it should be watered immediately and must be thoroughly watered after drying. In summer, the basin soil is often cracked because it is too dry, so watering can not be completed at once, otherwise the water leaks straight through the cracks, and most of the basin soil is still very dry. Wait a moment after the first watering and water again after the soil cracks are closed.

If you forget to water for many days, resulting in plant drought and wilting, do not rush to water, first move the potted flowers to a cool and ventilated place, spray the leaves with a spray can for 2 or 3 times, wait for the leaves to slow down, then a small amount of water, and so on after the root system resumes water absorption function, and then thoroughly watered. Careful watering in midsummer and cold winter

Water temperature has a direct effect on the root physiological activity of flowers. If there is a great difference between water temperature and soil temperature (more than 5 ℃), watering will cause a sudden change in soil temperature and damage the roots, but affect the absorption of water by the roots, resulting in physiological drought. Therefore, watering is better when the water temperature is close to the soil temperature, especially in winter and summer. In winter, it is best to store the water indoors for a period of time, or slightly add warm water to raise the water temperature to 15: 20 ℃, and then irrigate. In summer, you should avoid watering in the hot sun and high temperatures at noon.

Watering method of tree stump bonsai in summer

In order to keep the stump bonsai plant short leaves small, energetic old, different from the general potted plant, it is necessary to control watering. Such as Pinus massoniana, Pinus massoniana and other new buds put leaves, if too much watering, will make the leaves grow thick and broad, new branches grow only, destroy the original tree type. Plum blossom, wisteria and begonia reduce the amount of water during flower bud differentiation, which can not only make the branches short and strong, but also increase the number of flower buds.

In terms of season, after leaving the house in spring, there is not much water needed before the leaves germinate. The branches and leaves need to be watered more after they are sent out.

Branches and leaves grow too much, in order to control, they can be watered when the branches and leaves begin to wilt, and the amount of water should not be too large. In summer, Ye Maozhi is strong, the temperature is high, the evaporation is large, and the watering times and water quantity should be increased appropriately.

Watering time, early in the morning, late in the afternoon, generally watering twice in the morning and evening. The weather turns cool in autumn, which is also a suitable period for growth. in order to prevent autumn shoots and increase cold resistance, the amount of water should be properly controlled to keep the basin soil moist, just like spring, watering once every morning.

Winter, especially into the room overwintering plants, enter the dormancy period, because the temperature is low, evaporation is small, avoid over-tide, watering time should be around noon.

Key points and matters needing attention in watering bonsai with tree stump in summer

On the specific grasp, we should pay attention not to make the basin soil too dry or too wet, and pour enough water after the basin is put on or changed, so that the water flows out from the bottom of the basin. Water should be watered once the next day after fertilization. During the growing period, the stumps of deep pots and large pots should be watered frequently because the soil is easy to dry.

Be sure to see the basin soil dry before watering.

In general, the amount of water in the germination and flowering period is higher than that in the dormant period, more in summer than in spring and autumn, and the amount of water should be larger when it is windy or dry. It should also be mastered according to the texture of the basin, the general mud basin is breathable, the basin soil is easy to dry, the leaves such as pines and cypresses are small, hard and thick, those with wax and hairy evaporation should be watered small, and those with wide leaves and much water loss should be watered more.

Bonsai stump planted in the basin, generally shallow soil is thin, water in the soil is not easy to maintain, plus high temperature in summer, water is easy to evaporate, stump water demand is large, if you do not water the stump in time, it will lead to water shortage, dry stump, basin soil dried up and died. How to correctly meet the watering requirements of tree stumps in summer, we must master the following points:

1. It is necessary to master the basin soil and water temperature. General watering, basin soil temperature and water temperature should be kept the same or similar, such as basin soil temperature and water temperature difference is too big, can not be poured. Water in summer should be watered when the water temperature is the same as or close to the soil temperature and air temperature.

2. Pay attention to the water quality of watering. It is better to water the bonsai stump with Rain Water, river and pond water. Especially for the acid-loving stumps in the south, it is best to be irrigated with Rain Water, or with river or pond water. But in the north, because the soil is partial to alkali, the river water and pond water also contain saline-alkali ingredients. Watering flowers with this kind of water is disadvantageous to the growth of sour flowers and trees. If there is no Rain Water pouring pile, you can dilute the pile with mature Amoy rice water. In addition, the waste water from tap water and goldfish tank can also be watered with neutral and alkaline stumps. If tap water is used, it is necessary to let the chlorine in the water run away for a few days before it can be watered. Laundry water containing soap, saline-alkali water and chemically contaminated water should never be used to pour piles.

Watering depends on the change of the weather. In addition to watering once every morning and evening, water spraying and watering should be added around noon. In addition to spraying leaf surface, basin surface and pile body, the basin pile ground should also be often sprayed to maintain the air humidity around the basin, so as to prevent the basin pile from watering yellow leaves, dry leaves and scorched leaves on overcast and rainy days, and water cannot be accumulated in the basin to prevent long-term stagnant water from rotting the roots and causing the pile to die.

4. It depends on the size, depth and quality of the bonsai basin. The stumps with small and shallow pots are watered more often. The basin is large and deep, the water content of the basin soil is more, and it is impervious to evaporation for a while, and the watering times are correspondingly less. Watering should be treated differently according to basin quality. Tile basin water permeability is good, basin soil is easy to evaporate, easy to dry, watering times should be more, the amount of water should also be larger. Pottery basin, stone basin, glaze basin and plastic basin, the basin wall is impervious, impervious, basin soil is not easy to dry, watering times should be less, the amount of water should also be less.
