How to cultivate begonia flowers purchased online?

After you just buy the begonia flowers, you don't have to be in a hurry to plant them first. Check the root system of the plant first, some plants have rotten and dry roots, if there is such a root system, it is necessary to cut it, and then it needs to be disinfected and dried. Prepare a pot of the right size, fill it with some soil, put the treated plants in it, and bury the roots with the soil, and the roots must not be exposed to the soil.

1.Illumination. Begonia flowers love sunlight and are suitable for growing in sunny places. If left to grow in a place with poor sunlight, the begonia flowers will not bloom due to poor growth.

2.Temperature. Begonia flowers have strong cold tolerance, and the suitable survival temperature is between 10 and 30. In winter, when the temperature is below 10, it is easy to get frostbite, so you need to take measures to keep warm.

Planting time. Begonias are generally planted in spring and autumn because the temperature and light conditions are suitable and the ventilation is good. The spring option takes place in the month, while the fall season takes place in the month.

Germination treatment. In order to improve the germination rate of begonia seeds, the seeds need to be germinated before planting. The specific steps are:

Soak the seeds first, select the floating bad seeds and empty seeds, then choose a cotton gauze with strong water absorption to cover the seeds, and put them in a room of about 15-25 degrees Celsius, during this process, you need to change the water and clean the seeds every day to avoid moldy seeds, until the seeds are exposed to the white part and then the seeds are sown. Sow the germinated seeds, cover the soil and water them, remember to sow each seed 30 cm apart, face the white part up, and the soil should not be too thick, about one centimeter or so.

Begonia, which likes sunlight, can also tolerate semi-shade, cold resistance, and is not strict with environmental requirements, and is suitable for growing in loose and fertile, deep soil layer and well-drained sandy soil. Begonia has strong adaptability, and the cultivation management is relatively extensive.

Watering should adhere to the principle of "not dry, not watering, watering is watering thoroughly".

Apply a little more phosphorus and potassium fertilizer during the pregnancy bud period.

Begonias are afraid of waterlogging, otherwise they are easy to rot their roots, so watering must be moderate, and they can be watered appropriately several times a year in the dry season, and they should be watered less or no before the spring of the following year from October to the following year. Fertilization can be carried out after flowering, with rotted human and animal fertilizer, manure 1-2 times, and the old branches and shoots are cut off to promote their germination of new shoots; Apply organic fertilizer again after autumn to increase the amount of flowering in the following year. When the temperature is lower than minus 20 in winter, outdoor plants need to pay attention to cold protection, and potted begonias can be moved indoors for wintering.

It is best not to apply during the flowering period, and if you want to apply, you can apply a little phosphorus and potassium fertilizer appropriately.

Four seasons begonia in summer to avoid direct sunlight and rain, it needs to be properly shaded and sheltered from the rain. The second point is that when watering potted begonias, you need to wait for the soil to dry before watering. The third point of fertilization is that during the growing period, we can be a general-purpose water-soluble fertilizer every ten days or so, and potassium dihydrogen phosphate can be applied before flowering to promote the formation of flower buds.

The propagation of begonia flowers includes grafting, striping, dividing and sowing.

Grafting should be cut before germination in early spring, and rootstocks can be selected from vitex or begonia seedlings that have grown for more than 2 years. The seeds are sown after harvesting or sown in spring after sand storage, and germinate in early summer, and the seedlings become flowers slowly, taking about 10 years to flower.

In addition, the seedlings will produce variation, can not maintain the original excellent characteristics, generally use the grafting method to propagate.

Cutting the roots and tillers should be carried out in the spring, and the flowers will bloom the following year.

Begonias need to be transplanted with soil, in winter or early spring, digging holes in the barren soil to add some organic fertilizer as well.

Begonia flowers (mains spectabilis) are also known as pear blossoms and begonias. Rosaceae, apple genus. It is one of the famous ornamental flowers and trees in our country, not only the flowers are gorgeous, but also the fruits are exquisite.

1) Morphological characteristics and varieties.

A small deciduous tree with a broadly ovate crown and leaves elliptic to oblong-elliptic with finely serrated leaves. Flowers 5 7 clusters, umbel-shaped racemes, red when not opened, gradually pink after opening, mostly semi-double, there are also single-petaled, pear fruit globular, yellow-green.

Begonia resources in China are relatively abundant, and the common ornamental cultivators in the same genus are: M Halliana, M Hapehensis, M mlcromalus, M Pranifolla, M Baccata, etc.

2) Ecological habits.

Begonias like sunlight, are not shade-tolerant, have strong adaptability to severe cold climates, and are also very resistant to drought. Most species are best grown in sunny areas with high dryness, and some species can tolerate some degree of saline-alkali land. It prefers to grow in deep, fertile, pH5 5 pH7 0 slightly acidic to neutral loam.

Begonia has strong tillering power. The phenological period varies with latitude, altitude and species.

c) Methods of reproduction.

It is commonly used for seeding, dividing and grafting.

Sowing can be sown in autumn or spring after sand storage. Seedlings grow slowly, take 5 to 6 years to flower, and often mutate, so they are only used for rootstock cultivation and cross-breeding. Horticultural varieties are mostly propagated by grafting, with vitex or begonia seedlings as rootstocks, branches and buds can be grafted, and branches can be cut and split, and buds are mostly grafted with a "D" shaped grafting method.

The branches are mostly in early spring before budding or after defoliation in autumn and winter.

4) Cultivation techniques.

Begonias are generally planted in many rows, and can also be used as potted plants. The planting time is suitable before budding in early spring or after falling leaves in early winter, and maintaining the integrity of the root system of seedlings is one of the keys to planting survival. After planting, it is necessary to strengthen support management, fertilization, and soil loosening.

Prune after leaf fall and before budding in early spring, and remove weak branches, diseased and insect branches to keep the canopy evacuated and ventilated and light-transmitting. In the event of a spring drought, irrigation should be carried out. And pay attention to the prevention and control of beetles, leaf rollers, aphids, bouch moths and red spiders and other pests, as well as rot disease, red star disease and other diseases.

Trim at the right time. Prune too dense and too thin branches, dead branches, diseased and insect branches before budding in early spring every year, which is conducive to ventilation and light transmission, promotes growth and flowering, and reduces the occurrence of pests and diseases; For the old plants to renew the old branches, in the grass spring, the large branches with few small branches are cut off with a sharp saw, after germinating new branches, select a few strong branches, cut off the weak branches, and cultivate for another 1 year to flower.

Fertilizer and water management. Plant in early spring before bud germination, and apply well-rotted organic fertilizer before planting. After the leaves fall in autumn every year, dig a trench in the rhizosphere and apply decomposed organic fertilizer, and water thoroughly after covering the soil.

Adult plants should not be watered too much, and more water is easy to produce yellow leaves. Generally, water 2 or 3 times in spring, 1 2 times in summer and autumn, and 1 time in winter.

Pick the fruit in time. The young fruits should be removed in time after the flowers are harvested to save nutrients and increase the number of flowers in the coming year.

Pest control. Xifu begonia is susceptible to aphids, red spiders, scale insects, longhorn beetles and other pests, and needs to be sprayed in time to prevent and control.

Pay attention to water retention, ventilation and maintain scattered light.

Sister, Begonia flowers generally bloom from April to May, and the fruit is ripe in September. Watering should be dry and wet. The potting soil dries quickly, that is, when the potting soil is dry for 2 3 years, water.

To pour it is to be poured thoroughly. You can't just water it when it's okay, and the water will rot the roots for a long time. It should not be too dry, if the leaves have wilted, it means that it is too late to water, and quickly water to remedy.

Also, my sister remembers to fertilize and gives you an easy way: just put the eggshells in the flowers and compost them. You can look for the rest, and find a gardener who can help you.
