Four Seasons Conservation of Flowers-Summer

Summer is hot and the rainfall increases, which is the vigorous period for most flowers to grow and develop, and it is also a good time to cut flowers and trees. But this season is also a period when a large number of diseases and insect pests occur, so we should take care of flowers more carefully.

1. Water frequently.

In summer, the temperature is high and the water evaporates quickly, so potted flowers should be watered in time.

However, different flower varieties have different characteristics and different requirements for water.

Like wet flowers, such as narcissus, bamboo, calla lily, etc., need enough water.

Like moist flowers, such as Milan, jasmine, oleander and hibiscus, they are usually watered once in the morning, once in the afternoon and once in the evening.

Don't water at noon. It is best to water it every morning and evening in summer.

At noon in midsummer, the temperature is high. At this time, the surface temperature of the mosaic can often be as high as 40, with strong transpiration and rapid evaporation of water. In order to replenish water to the leaves in time, the roots need to constantly absorb water.

If the flowers are watered with cold water at this time, the soil temperature will drop sharply, and the root hairs of the roots will shrink immediately due to the stimulation of low temperature, which will hinder the normal absorption of water.

At this time, there is no preparation in the flower body, the stomata on the leaf surface have not been closed, and the water continues to lose. This will lead to excessive water loss in leaves and imbalance between water supply and demand in plants, which will lead to "physiological drought", which will scorch leaves and even lead to plant death in severe cases.

This phenomenon is very obvious in herbaceous flowers, such as geranium and cuiju. In hot weather, I am most afraid of splashing cold water at noon.

Pay attention to moisturizing and cooling.

In summer, some grass can be covered on the basin soil, so that the sunlight is not directly directed to the basin soil, the temperature of the basin soil can be reduced, and the water in the basin soil can be prevented from evaporating too quickly.

You can also spray the leaves of Hua _ with a sprayer, and at the same time sprinkle water around to moisten, reduce the temperature and increase the humidity.

This is very beneficial to some flowers that like cold.

2. The brightness of flowers

The hot weather and strong sunshine in summer are not conducive to the growth of flowers, especially flowers exposed to the scorching sun for a long time, which are easily damaged or killed. Of course, some flowers are happy, and the illumination time can be extended appropriately.

So different flowers should be treated differently in summer.

Sunshine-loving flowers, such as poinsettia, chamomile, pomegranate, Milan, fig, rose, hibiscus, Prynne, etc., can be kept in sunny places, but when the sun is too strong, we should also pay attention to proper shade, such as Milan, Prynne, Hibiscus, Chrysanthemum, etc.

Orchidaceae, Hosta, Compositae and Camellia _ need to be maintained under well-ventilated weak light or astigmatism conditions.

At the same time, flowers should be shaded and cooled to prevent heatstroke.

3. Pay attention to ventilation

When the temperature exceeds 30C, indoor flowers should pay attention to ventilation, open the window and let fresh air flow into the room, so as to play the role of cooling and heatstroke prevention.

fertilize the soil or land

Smallpox grows rapidly in summer, so we should supply enough fertilizer to the flowers in time.

Fertilization also needs to be treated differently according to the variety of flowers. Ordinary flowers can be applied with decomposed dilute liquid fertilizer once every 7- 10 day. For flowers in acidic soil, alum fertilizer can be applied once every 10 day.

Be careful not to splash fertilizer water on the leaves when applying fertilizer, otherwise it will easily damage the leaves.

Fertilization in summer should be carried out in the evening.

Pay attention to loosening the soil before fertilization, which is beneficial to the root system to absorb fertilizer and water, to the reproduction and growth of microorganisms, to accelerate the decomposition of organic matter in the soil, and to provide more nutrients for the growth and development of potted flowers.

Pay attention to watering the next day after fertilization.

prune

The pruning of potted flowers in summer mainly includes core removal, bud smearing, leaf picking, flower thinning and fruit thinning.

For some spring-sown grass flowers, when they grow to a certain height, they should be picked in time to make them branch and bloom more.

For some woody flowers, such as kumquat, when the annual branches grow to 5-20 cm, the core should also be removed to concentrate nutrition and facilitate flowering and fruiting.

In summer, adventitious buds often appear on the stems or stems of some flowers, which disturb the plant shape and consume nutrients and should be removed in time.

For some ornamental flowers, such as chrysanthemum, camellia and rose, too many buds should be removed so that bloom can grow big and bright.

For pomegranate, kumquat, bergamot and other ornamental flowers, if it is necessary to pick off some young fruits in time, generally only one fruit is needed for the short fruit branch, so that the grown fruit will grow big and bright because of its rich nutrition.

In addition, the long branches of plants should be cut off and shaped in time.

breed

Summer is the best time to cut some evergreen flowers, such as Milan, Jasmine, Rhododendron, Fusang and other flowers are easy to survive during this period.

For plum blossom and peach blossom, summer is a good time for them to germinate, and for Prynne, it is a good time for them to dock.

Summer is also the best time to plant some potted flowers. For example, Ilex kudingchi, planted in July, can blossom around the National Day.

Chrysanthemum is sown in July and August, and it can also bloom in the severe winter and few flowers season.

Pittosporum macrophylla and carnation are sown in August-September, and can bloom in the summer of the following year.

Ornamental flowers in winter, such as primrose, Zhu Dinghong and geranium, should be planted in June and July.

Begonia, azalea, camellia, Milan, gardenia, honeysuckle and some tropical foliage flowers were pruned in June and July.

Calla lily, azalea and other flowers can breed in summer.

Flowers such as rose, kumquat, camellia and some cacti can be grafted in summer.

For plum blossom, azalea, osmanthus, jasmine and other flowers, layering can be carried out in June-July.

7. Pest control

After the summer, all kinds of pests and diseases do great harm to the growth of family potted flowers.

When the weather is too hot or too humid, bacteria will multiply faster.

Pest control, such as itchy peppers, house dust mites, red spiders, etc., mostly appear in rose, azalea, American ginseng, Podocarpus and other flower markets, and a small amount of trichlorfon and other drugs can be caught or sprayed.

The inchworm mainly harms pomegranate, boxwood and other flowers, and can be sprayed with trichlorfon or caught artificially.

Roses and impatiens are easy to be infected with powdery mildew, and there will be symptoms such as yellow leaves, dead leaves and bent shoots.

Pay attention to the ventilation and light transmission of flowers, and apply less nitrogen fertilizer and more phosphorus and potassium fertilizer. For newly infected plants, 15% triadimefon can be sprayed once, and 700- 1000 times water can be added.

8. Be careful to protect dormant flowers

For example, cyclamen persicum, upside-down golden bell, Erythrina macrophylla, calla lily, geranium and lotus are dormant or semi-dormant in high temperature season, when metabolism is slow and growth is stagnant.

According to the growth characteristics of these flowers, careful care should be taken to make them pass the dormancy period smoothly.

Put these flowers in a cool and ventilated place to avoid strong light and rain, otherwise the roots will easily rot or even die because of wet soil.

In addition, it is necessary to control watering, otherwise the pot soil is too wet and easy to rot; Of course, don't use too little water, otherwise the roots will shrink and keep the soil slightly moist.

For these dormant flowers, there is no need to fertilize, otherwise it will easily lead to root rot and even death of the whole plant.
