What is the culture method of geranium (hydrangea)? Is it a begonia flower? What's going on with Ye Zihuang?

Geraniums, also known as hydrangea, stone red, mosquito repellent grass, foreign butterflies, etc., are shrubs and flowers of the Niu Niu Seedling family, with red, orange, pink and white flowers. If they are properly maintained, they can blossom all the year round. What is the breeding method of geraniums? Is it a begonia flower? What's going on with Ye Zihuang?

What is the breeding method of geraniums?

1. Soil and reproduction: geranium is suitable for survival in sandy soil, which can be prepared with humus, garden soil, river sand and organic fertilizer, or fine sandy soil, humus, perlite and organic fertilizer. Geranium can be sowed and propagated by cutting, sowing and reproduction can be carried out in spring and autumn, and the optimum temperature for germination is 20-25 ℃. After sowing, the soil should not be deep and germinate for about 2-5 days. Cuttings can be propagated except semi-dormant plants in summer. After cutting cuttings, the cuttings were cut and dried for several days and then planted in the substrate. After cutting, the cuttings were kept at room temperature for 13-18 ℃ and rooting for about 14-21 days.

2. Temperature, weather: the suitable temperature for the growth of geraniums is 10 Mur20 degrees Celsius. If the temperature is too high, it will enter a semi-dormant state, and if the temperature is too low, it will be susceptible to cold injury. There should be plenty of sunshine in spring and autumn, and it is too hot in summer to be exposed to direct sunlight. It can be placed in a cool place, and plants will be frostbitten if it is too cold in winter. Pay attention to keeping warm. To avoid strong wind and heavy rain weather, strong wind weather will blow broken geraniums, heavy rain weather will make geranium roots soaked by Rain Water and cause rotting roots.

3. Watering and fertilization: pelargonium can be watered once every three or two days in spring and autumn to keep the soil moist and without stagnant water, less watering in summer, no watering in cloudy and rainy days, less watering at low room temperature in winter and more watering at high room temperature. During the growing period, the geranium should apply liquid fertilizer every 10-15 days and every 7-10 days in the peak growing season. Nitrogen fertilizer should be applied before budding and phosphorus and potassium fertilizer should be applied after budding. Fertilization should be stopped if the room temperature is relatively high in winter and should be applied appropriately at high temperature in summer.

4. Pruning and shaping: in order to make the crown shape of the geranium plant plump and compact, pick the heart to promote new branches when the seedling is 10 cm high, pick the heart 1-2 times after the new branches grow, pick flowers and prune them in time after each flowering, promote new branches and blossom continuously, cut off the shedding flowers after flower shedding, and timely thinning and shaping.

Is the geranium a crabapple flower?

Geraniums are not crabapple flowers because:

1. Different species and genera, geranium is a perennial herb of the order Niuer Miaomiao, Pelargoniaceae and Pelargonium, with a height of 30-60 cm. It is very popular in Africa and Europe, and it is the national flower of Hungary. Begonia is a rose order, Rosaceae, apple tree, up to 8 meters high, known as "immortal in the flower", "flower imperial concubine", "flower noble", and has the artistic conception of "jade tang rich".

two。 Different habits, the suitable temperature for the growth of geranium is 15-20 ℃, if the temperature is too high, the plant will be in a semi-dormant state, and if the temperature is too low, it will suffer frost injury; the crabapple flower is extremely hardy and can grow well at minus 15 ℃.

3. Different stems and leaves, pelargonium stem erect, with obvious nodes, densely pubescent, petiole 3-10 cm long, pilose and glandular hairy, leaves round or reniform, margin rounded teeth, leaves transparent pubescent on both sides; begonia branchlets stout, pubescent when young, glabrous when old, petiole 1.5-3 cm long, pubescent, leaf blade elliptic to long elliptic, margin closely serrulate, old leaves glabrous.

4. Flowers are different, pelargonium flowers are axillary umbels, petals are broadly Obovate, flowers are red, orange, pink or white; crabapple flowers are nearly umbellate, petals ovate, flowers are white and pink.

Third, what is the yellow leaves of geraniums?

The reasons for the yellow leaves of pelargonium are improper watering, improper fertilization, temperature discomfort, diseases and insect pests, etc., too much watering and fertilization of geranium will lead to rotten roots and burn roots, so it is necessary to immediately control water and fertilizer, and change soil in serious cases; long-term lack of water and fertilizer will lead to yellow leaves and withered leaves, so they should be watered immediately and fertilized properly; excessive temperature and sun exposure will lead to leaves yellowing and dying, which can be moved to a cool and ventilated place. Too low temperature, lack of light will also lead to leaves yellowing, to maintain the right temperature and sufficient light; diseases and insect pests will lead to local necrosis, yellowing and shedding, spray control.

Is the geranium poisonous?

The whole plant of geranium is poisonous, as long as the skin does not touch its juice, otherwise it will cause redness, swelling and itching. Try to wear gloves when pruning branches, leaves and flowers. But its fragrance is non-toxic, and the flower scent is like mint, which can regulate hormones, stimulate lymphatic detoxification and balance skin oil secretion. it is still a good insect repellent, but it is not suitable for those with allergic skin and those with pregnant women and babies at home.
