How to raise Anthurium andraeanum in summer? Guidelines for summer maintenance of Anthurium andraeanum

How to raise Anthurium andraeanum in summer? Anthurium andraeanum can also be called red goose palm, fire crane flower, andzu flower, candle, native to Costa Rica, Colombia and other tropical rain forest regions, the plant flowering period is long, the flower appearance is strange and beautiful, and it is often used for garden beautification or ornamental. But recently, some flower friends have some problems in the process of breeding Anthurium andraeanum, so the editor will talk about Anthurium andraeanum summer maintenance guide today, hoping to be helpful to everyone.

Guidelines for cultivation and maintenance of Anthurium andraeanum in summer

1. Astigmatism environment

Anthurium andraeanum needs a certain amount of light in the process of growth, so it is necessary to put astigmatism in indoor planting to meet the light needs of Anthurium andraeanum.

2. High humidity environment

Anthurium andraeanum has high requirements for air humidity in the growing environment, and the relative humidity in the air must be more than 50%. Therefore, in order to meet the humidity requirements of Anthurium andraeanum, you can put a pot of water next to the Anthurium andraeanum potted plant, or spray more water on the leaves to increase the humidity.

3. Ventilation environment

Anthurium likes to grow in a high humidity environment, but because it is fleshy, it is easy to rot when there is too much water in the soil and high humidity, so it is necessary to strengthen ventilation while ensuring humidity, and place Anthurium andraeanum potted plants by the window where there is no direct light.

Matters needing attention in summer culture of Anthurium andraeanum

1. Yellow leaves

A. Too much watering

Although hot water evaporates quickly in summer, if you water Anthurium andraeanum sooner or later, it will cause yellow leaves because of too much watering, so it is necessary to reduce the amount of water in a short time and put Anthurium andraeanum potted plants in a well-ventilated place to speed up water evaporation.

B, the light is too strong

If the Anthurium andraeanum is placed in a place with strong light, it will cause the leaves of the Anthurium andraeanum to scorch, so it is necessary to move the Anthurium andraeanum to the astigmatism environment for about seven days.

2. Blade cracking

A, the humidity is too low

The main reason for the cracking or blackening of Anthurium andraeanum leaves is caused by low humidity in the growth environment, so it is necessary to place Anthurium andraeanum in a relatively large space, and at the same time put a basin of water next to Anthurium andraeanum to increase humidity.

B. Direct illumination after spraying water.

Anthurium andraeanum saw direct light or strong light after spraying water, which will lead to leaf cracking, which requires more attention from all flower friends.

3. Rotten root

Too much watering causes long-term stagnant water during the growth of Anthurium andraeanum, resulting in rotten roots.

Third, measures to solve the problem of rotten roots.

1. Remove the rotten Anthurium andraeanum from the basin and remove the excess soil and rinse it with clean water.

2. If there are more Anthurium andraeanum, it is necessary to split the roots, cut off all the rotten roots with sterilized scissors, only disinfect them in potassium permanganate solution for half an hour, and then put them in a ventilated place to dry. About a week later, you can get normal maintenance in an astigmatic environment.

It should be noted that cold-resistant species can only be divided in the greenhouse.

Management of flowers planted in courtyard

1. Transplanting in areas where the weather is not too cold, the species of grass flowers that can be transplanted and planted in the courtyard are: carnation, kale, calendula, daisies, etc.; in the colder areas in the north, carnation, primroses, calendula, goldfish grass and pansy can be planted in the pot first, put in the greenhouse, and then transferred to the outside of the shed or planted in the courtyard after the return of air in spring. Due to the particularly cold weather this month, some evergreen trees, such as camphor, French holly, privet, du ying, Schima superba, magnolia, sweet-scented osmanthus, and so on, can continue to be transplanted according to conventional methods in the south of the Yangtze River, while in the north of the Yangtze River, measures such as intensity shearing, bringing soil balls, section sealing wax, trunk rope wrapping or binding plastic film moisturizing can ensure the normal survival of the trees. This month, most deciduous shrubs and green trees can be transplanted and planted in the courtyard. Such as hibiscus, pomegranate, bauhinia, begonia, ginkgo, maple, wax plum, plum blossom, white magnolia, purple magnolia, free from disease, Lingxiao, Linden, Liriodendron, green peach, tallow, red spiraea, incense, rose, rhododendron plum, dragon claw and so on. This month, we can also combine afforestation and land preparation in forestry to collect wild tree stumps, such as elm, sparrow plum, triangular maple, wisteria, wintersweet, Elaeagnus angustifolia, wolfbone holly, oak, Yingrihong, southern bamboo, etc., after giving strength shearing, carry out shallow burial and high cultivation, and cover grass curtain to prevent cold, which can be used to make tree stump bonsai after survival.

2. Pruning hedges, balls and flowering shrubs that have not been pruned in December should continue to be pruned. According to the different growth characteristics and tree shape requirements of flowering shrubs in the base area, different standards are adopted, which generally require cutting off disease and insect branches, thin and weak branches, dead branches, shrinking long branches and disordered branches, so as to make the flowers and trees tend to be beautiful in appearance and light in the inner chamber. Hedges, green walls, color blocks, etc., continue to be trimmed in accordance with the requirements of straight lines, flat faces and angular angles, while the pruning of balls and other geometric plants requires smooth curved surfaces and flat straight faces. The pruned branches and leaves should be concentrated and burned and can be used to make farm manure.

3. Watering for ornamental plants such as flowers and shrubs transplanted in late autumn and early winter last year, attention should be paid to watering management, which can be watered every 7 to 10 days. If there is more dust on the leaves, the canopy can be sprayed at noon in fine weather. It should be noted that the leaves had better be dried in the afternoon to prevent water droplets from remaining on the leaves, otherwise they would encounter a special low temperature in the early morning of the next day and frost or freeze on the leaves, which would cause a certain degree of damage to the leaves. In order to prevent water evaporation near the plant, rice straw can also be covered within a radius of 1 to 1.5 meters around the tree canopy after watering, which can not only keep moisture, but also protect the root system.

4. fertilizing the southern region, for the grass flowers transplanted in late autumn and early winter, such as carnation, cherry cherry, Fu Lukao, daisy, pansy, calendula, etc., as long as the temperature is not too low, we can continue to apply low concentration dilute liquid fertilizer to promote its normal vegetative growth. For the flowers and trees planted in the courtyard that have not yet completed winter fertilization, such as sweet-scented osmanthus, camellia, plum blossom, wax plum, rose, crape myrtle, bauhinia, pomegranate, begonia, Michelia, magnolia, Yingchun, golden bell, hypericum, broad-leaf ten meritorious fruits, Phyllostachys pubescens, pyracantha, etc., we should lose no time in digging ring grooves around their roots and burying appropriate amount of compound fertilizer or cake fertilizer. Generally, 1 to 2 jin of compound fertilizer or 1 jin of dry cake fertilizer can be applied per plant to meet the needs of sustained growth in that year.

5. For pest control, the litter of cut flowers and trees should be centrally burned; at the beginning of this month, for the species of south trees moving northward, the trunk should be bundled with grass rope as soon as possible to keep the bark from freezing; for thick flowers and trees that have not yet been whitened, it should also be completed at the beginning of the month; cleaning up the weeds and leaves in the courtyard and burying them centrally can significantly reduce the occurrence of diseases and insect pests in the coming year. Plant ash can be applied to remove the overwintering aphids on the plant, and the egg blocks and pupae found on the tree trunk should also be scraped off in time.

6. at the beginning of this month, the plots in the courtyard that are going to be used for cutting, sowing and planting this year should seize the time to dig, and at the same time, cake fertilizer, pond mud, barnyard manure and so on should be applied to reduce the harm of underground pests to sowing seedlings after freezing. The harm of underground pests to sowing seedlings can be reduced, and the free space under big trees should also be dug, so that the occurrence of diseases and insect pests can be reduced.

7. Prepare fertilizer to dry the litter, leaves and weeds cleared from the courtyard, accumulate with the garden soil, ignite and burn, and form a fire-irrigated soil that can be used for sowing and covering soil or preparing potted soil; put vegetable cake, bean cake, chicken droppings and pigeon dung into the tank, add water and seal fermentation, in preparation for watering potted flowers, bonsai and ground flowers. Pig manure, chicken urine and cake fertilizer are mixed with pond mud and garden soil, which can be used to prepare culture soil or to be used as topdressing for flowers and trees.

8. There are not many seeds that can be harvested this month, only those ornamental plant species whose fruits can store branches for a long time, such as Phyllostachys pubescens, Firethorn, holly, rich seeds, lobular privet, privet, red maple and so on. The seeds should be treated in time after harvest, and sand storage should be given to accelerate germination in preparation for sowing between March and April. The mature asparagus, magnolia and winter coral in the simple greenhouse are sown as they are picked.

9. Check the seeds stored in sand this month, including Magnolia, Michelia, Magnolia, heather, holly, etc., to see if the seeds are moldy. If mildew occurs, rinse in time and replace clean river sand storage; if the seeds are found to be dry, they should be given appropriate spray humidification; if some seeds are found to be white, sow in time and cover with plastic film to keep warm and moisturizing. Check the root of Dahlia and the underground stem of canna stored indoors to prevent mildew.

Management of potted flowers in courtyard

1. Watering pines and cypresses that are not afraid of cold and potted plants such as ginkgo, wax plum and plum blossoms placed in the courtyard should be watered around noon every half month to keep the basin soil moist without causing ice on the basin. For potted flowers and trees that have been moved to a simple greenhouse, such as plum blossom, camellia, tea plum, Ruixiang, Belgian rhododendron, etc., because their stems are in the expansion or early blooming stage, in addition to watering the potted soil, attention should also be paid to spraying water on branches and leaves to create a humid environment. For foliage plants shelved in the greenhouse, basin soil watering should also be controlled, the foliage can be sprayed once a week around noon, and the water temperature should be basically the same as that of the greenhouse to prevent damage to leaves and roots.
