robust nature, very few pests and diseases; its adaptability is also strong, the species could grow in soil, humus-rich sandy loam but the most benign growth; hi sunshine, a good warm, slightly drought, fear of water, endure summer's heat and the scorching sun exposure. Summer plants stop growing, leaf senescence, was half-sleep state, then you can go to the shade outdoors, stop applied fertilizer, watering, the rain brought down the basin to prevent water rot.

to September summer days cool off, this time can be Fanpen for soil, cut the branches first, leaving only the base of each branch is about ten centimeters, so that new branches re-grow new shoots replace. Geranium watering should be moderate, not too wet basin earth to pour half a day after the semi-shaped basin earth was appropriate.

geranium propagation by cuttings based, multi-line in spring and autumn, but the winter greenhouse equipment are also inserted. General spring inserted in the New Year and Spring Festival are available between the flowering; plug may fall flowering in late April. Cuttings with the new and old branches, but the growth of branches after inserting young shoots best. Cuttings of about ten centimeters election to retain the top two to three leaves, such as articles or not with the old blade will cut a little line dried, inserted in the clean sand. Should be kept slightly damp sand, do not flood. Half shade to keep the first set does not withered leaves, three to five days and then gradually exposed to sunlight. Generally about two weeks to take root, to root length three to four centimeters on the pots when you can.

M. buster Dick by the Dutch geneticist geraniums will be native to Africa with gene fusion technology Citronellal lemongrass in import, the role of culture as a mosquito repellent M. buster. Subsequently, the Dick Corporation in the United States set up a gene, a large-scale promotion of this technology, and later spread to Japan and Australia. Why be afraid of mosquitoes

M. buster it? The original is because the inside has a special The product of transgenic technology, will have the mosquito gene - gene structure Citronellal implantation Also implanted with fresh smell and the role of air purification plant DNA (gene) structure, the formation of Particularly hot summer, refreshing, refreshing. Truly realized without spraying, do not smoke, bio-natural insect repellent,UGG shoes, without any side effects. Pelargonium is no doubt that modern high-tech biological engineering and the natural world the perfect combination of the best insect repellent products in human. The advent of the product of modern daily life and work of human improvement and maintenance of learning environment has epoch-making significance. Not yet M. buster, evening primrose and other aromatic plants emit the aroma, the exact proof of harmful

geranium southern Africa country of origin. Hi warm, humid and sunny environments. Poor cold tolerance, fear of wet and heat. 3 September optimum growth temperature was 13 ~ 19 ℃, the winter temperature is 10 ~ 12 ℃. 6 to 7 months between a semi dormant state, water should be strictly controlled. Should be fertile, loose and well-drained sandy loam. Winter temperature not lower than 10 ℃, short-term capability at 5 ℃. Species to be ill with artificial pollination in order to improve seed set. Spent about 40 ~ 50 days after the seeds mature.

geranium likes the cool, winter day, to keep the indoor I0-15 ℃, the night temperature of 8 ℃ or more, that can properly blossom. But the optimum temperature is 15 to 20 ℃. Geranium hi evil wet dry, not too much water in winter, to see dry see wet. Wet soil is soft stem quality, adverse initiation and open flowers; long-term plants too wet can cause excessive growth, squid, part of the students move up, the leaves gradually yellow and fall off. Growing geraniums need full sun, so put it in the winter to sunny place. Illumination is insufficient, leggy stems and leaves, stalk valuables, inflorescence dysplasia; low light tend to flower bud under the poor, early blight. Geraniums do not like big fat, too much fertilizer will grow too strong negative flowering geraniums. To make flowers flourish, pouring every 1-2 weeks - second thin book fertilizer (composting bean water) poured every 7 10 days 800 times a potassium dihydrogen phosphate solution can promote normal flowering. Ruins after the cut flower stems in a timely manner, you can increase the strain between the light, to induce germination of new leaves, stems out of the new topping

pruning geraniums to encourage more branching and more flowering plants to be more of times topping, in order to promote its increased branching and bud. Xie timely cut flowers after stray too close and cut the thin branches, so as to avoid excessive consumption of nutrients, but the winter Tian Han, should not be re-cut.

height 30CM-60CM, the whole plant was fine and glandular hairs, with a smell. Stem succulent. Leaves alternate, round to kidney-shaped, usually within the leaf margin horseshoe pattern. Inflorescences umbellate, with a total length of stems, flowers white, pink, red meat, pink, red and other colors, there are ill with Double the points and leaf masks white, yellow, purple markings Coleus varieties. Flowering May -6 months, in addition to summer dormancy, such as the environment appropriate to continue to blossom. Likes the cold, but not cold. Avoid high temperature, hi sunny, happy well-drained fertile loam; intolerance moisture or humidity and easy leggy, slightly resistant to drought. Optimum growth temperature is around 15 ℃ during the day and night, no less than 5 ℃. Summer dormancy or semi-dormant, should be set to half shade, and control moisture.

geranium is a perennial herb. Base slightly woody, stem succulent. Heart-shaped leaves, green, often with a horseshoe-shaped ring pattern. Inflorescences umbellate, buds drooping, corolla red, white, pink, orange and other colors, as well as single lobe, semi-double petals, double petals and tetraploid varieties. Common varieties of love (TrueLove), took ill with red. Fantasia (Fantasia), large flowers, flower semi-double petals, red. Chewing gum (BubbleGum),cheap UGG boots, two-color species, flowers crimson, pink bother. Purple Ball 2 Pei Baer (Purpurball2Penbal), semi-double petals flower, purple. Tango Violet (TangoViolet), large flower seeds, flower of pure purple. U.S. Bilodeau (Meloda), large flower seeds, flower semi-double petals, bright red. Jana (Jana), large flowers, two-color species, flowers deep pink, magenta bother. Samu Ba (Samba), large flower seeds, flowers dark red. Arava (Arava), semi-double petals flower, pale orange-red. Grape designer (DesignerGrape), semi-double petals flower, purple, with white eyes. Lost White (MaverickWhite), pure white flowers.

1. trailing geranium Pelargonium peltatum (L.) Ait. also called the shield or vine leaves geraniums geraniums.

its varieties are Amethyst (Amethyst), flowers purple; Lan Bada 98 (Lambada98), pollen red; Hong Yan (Shany), semi-double petals flower, deep red; Peng-dimensional (Penve), Flowers semi-double petals, pink; tornado (Tomado), took ill with white. Another tetraploid Pelargonium freckles (Freckles), pollen red; four times the red (TetraScarlet), large flower seeds, flowers bright red.

spring planting, planting the South to the North should be potted indoor winter. The general pot. Planted should be selected not easy to place water, soil requirements loose, fertile, well drained, preferably sandy loam. CD selection of leaf mold pots, garden soil and sand potting mixture. Before planting into the tiles in the pelvic floor to facilitate drainage. First planted in Xiaopen in general, will not cut into the basic fertilizer, conservation for some time before the pot into a larger, when applied in the pot into the maturity of the amount of manure as basal fertilizer, top soil into the culture, not with the basal root direct contact,

hi sunshine, in addition to the hot summer sun is very strong, need to put to shade or indoors, avoid direct sunlight, the other at all times should receive adequate sunlight, at least 4 hours a day The sun shone, so as to maintain a year-round flowering. If the illumination is insufficient, long-term growth areas in the shade, easy to leggy plants to reduce the flower buds. Optimum growth temperature 16-24 ℃, the spring and autumn, cool climate growth is most vigorous. Should be into the greenhouse in winter, the temperature should remain around 15 ℃ during the day and night of not less than 8 ℃, and to ensure adequate light, can continue to grow and blossom.

growing season to strengthen the water and fertilizer management. Thin liquid fertilizer applied 2-3 times per month, in the flower bud, it should increase the facilities into the phosphorus and potassium. Keep the soil moist to dry, and can not dry drought, or yellow leaves fall off, affecting growth and decorative value; but not too much watering, soil too wet, otherwise it would be leggy plants, affecting differentiation, small flowering and even the death of root rot. Should have quit without pouring water, and poured to Jiaotou principle. High summer temperatures, plants enter dormancy, watering system should be Zhu, stop fertilizing.

crown to make full compact plants, from seedlings to start pruning. When the general height of 10 cm topping, priming new branch. New shoots grow to be 1-2 times even after topping until the formation of a satisfactory individual plant. Flowers on the top branches, each time picking flowers pruning after flowering should, continue to trigger new branch, flowering without a break, usually in early spring, prune in early rehabilitation and autumn 3.

common planting and cutting propagation.

spring and autumn can be carried out in spring sowing pots indoors as well. Germination temperature for 20 ~ 25 ℃. Geranium seeds small, not deep casing after sowing, about 14 ~ 21 days to germinate. Autumn, summer will bloom the second year. The seed propagation of seedlings can be bred in the middle of excellent varieties.

than 6 to 7 months in a semi-dormant plants, but can be cutting. In spring and autumn as well. High summer temperatures, easy to black rot cuttings. Cuttings 10 cm long used to the top of the Ministry of the best growth potential Wong, rooting quickly. Scissor cuttings, let dry and cut the number of days to form a film and then inserted in the sand bed or a mixture of perlite and peat matrix, pay attention not to hurt the skin stem cuttings, or wound perishable. Inserted after the release of half shade, keep at room temperature 13 ~ 18 ℃, 14 ~ 21, including the natural root, root length can be 3 to 4 cm pot. 0.01% cutting process using acid soaked cuttings indole D base for 2 seconds, can improve the survival rate and rooting rate of cuttings. General cuttings flower cultivation for 6 months, ie January cuttings, June flowering; October cuttings, flowering the following year 2 to 3 months.

geranium adaptable, bright colors, long flowering period, suitable for indoor display, flower arrangement and so on. Following their greenhouse breeding technology are described below.

geranium tissue culture propagation can also be used. To MS medium with added 0.001% indole acetic acid and kinetin to promote explants produced callus and adventitious buds, with 0.01% IAA for rooting. Tissue culture method for the geraniums and breeding new varieties Diego education offers a new way.

Location: Geranium preferences have enough daylight to the east or south window, autumn and winter in the day, place half of the growth of good sunshine, but also suitable as a bedding plant. There must be those on the interior scattered light, or falling, leaves quickly.

soil: commercial culture soil or loose sandy loam rich in organic matter better.

Moisture: 1-2 days in autumn and winter time water can be poured, but sunny days the best watering once a day, especially the lush plant growth, the leaves and evaporates more quickly, care must be supplemented enough water.

sunshine: geranium like plenty of light, autumn and winter in full sun or half sun grow well at the flowering stage can appreciate the bright room, but if the brightness will not be easy and lower leaves yellow leaves, Petals of the phenomenon.

temperature: optimum growth temperature at 15-25 ℃, not high temperature, not suitable for summer growth.

fertilizer: soil should be mixed in the entire basal culture, about 1-2 weeks into flowering application of liquid is too fat.

care: home gardening are mostly purchased from the flower market, you can buy three kinds of flowers in a large box, and then on the window sill, or directly in the window flowers,UGG boots cheap, as long as you do not forget to irrigation, a few weeks later, your home will be a window where the most people.

geranium 12 to 15 cm height when topping, that may produce collateral. Summer temperatures, strict control of water, or semi-dormant geraniums, such as Pentu too wet, yellow leaves often fall off. Stem and leaf growth stage, each a half fertilizer 1, but not applying too much nitrogen. Reproductive shoots too, need to stop fertilization, and proper pluck some leaves, is conducive to flowering. Flower bud formation, applied every 2 weeks plus 1 phosphate. Or To control the height of cut lines, to spend large Seyan purpose, in addition to select other than the dwarf geranium varieties, growth regulators application is very important. When the geraniums planted in pots of 12 cm or 15 cm after 2 weeks, can be 0.15% CCC or foliar spray than for a long time, 1 time per week, spray 2 times, 14 to 18 hours light per day, which can effectively control the geranium height, to provide quality merchandise flower.

pluck flowers immediately after flowering Xie, so as not to consume nutrients, is conducive to the development of new flowers and flowering. Usually 3 to 4 old potted plants need to be updated. Winter and spring flowering, should be put sunny place, or drooping leaves turn yellow and easy. Yu Xuetian increase in artificial lighting, flowering even better.

geranium thermophilic fear cold, cold winter, special attention should be good antifreeze. Growing support in the northern region of geraniums, the advent of frost should be moved to indoor pot plant, on the sunny window, to fully accept the light. If the illumination is insufficient, the plant and leggy, the formation of flower buds, and even the formation of flower buds has also withered due to insufficient light. If in the south, also in the beginning of winter after the plants will be moved to sheltered basin warm sunny place, both for flower more than the sun, and easy to escape the cold. Temperature should be kept at room temperature 15 ℃ to 20 ℃, the night of not less than 10 ℃. Low temperature weak plant growth environment is not conducive to flower bud differentiation, flowering little or no flowering, but the temperature is higher than 25 ℃ environment for their growth, flowering is also negative. Geranium xerophilous fear of wet, so daily watering should be moderate, not every day more water in winter, even in dry weather, usually have five to seven days once the water poured, hold basin slightly wet to dry. Watering too much can cause yellow leaves fall off, thus affecting the flowering, and even cause rot and death. However, foliar spray with water often to keep leaves clean and conducive to the conduct of photosynthesis. To make continuous flowering geraniums, you need to supply adequate nutrients, usually every 10 days should be thin top dressing fertilizer once, can cake, shoe, Anabaena water mix preparation, adding water to be used after fermentation can also use the shop selling compound fertilizer, each only 3-5. Geranium branching more to promote its multi-flowering, plants were to be repeated on the topping, and promote its multi-branched, multi-bud. Xie cut flowers in a timely manner after stray too close or cut the thin branches, so as not to consume nutrients. However, the depth of winter, should not be re-cut.

geranium family commonly planted flowers, leaves and flower tours also arranged flower beds, flower diameter of good material. Because of its rapid growth, annual pruning shaping. Pruning on the plants usually at least 3 times. The first time in March, mainly thinning; the second time in May, to cut off the flowers and have been grateful too dense branches; the third time after the beginning of autumn pruning, mainly plastic.

generally dog days later, the cooler weather, the gradual resumption of geraniums growing, dormant buds of plants has grown. At this point it is late August to early September, the plants should be combined with a comprehensive Huanpen of pruning. According to plant growth, the general election to stay close to the base of the location of the growth of robust, well-balanced distribution of the main branch 3-5, other than dense, delicate leggy branches, cut off from the base together. And then the main branch and lateral branch stubs, leaving only the growth of each collateral robust cents bud, so evenly distributed throughout the plant branches, compact, stocky individual plant fullness.

year to cultivate the plants, you can stub in place. After a clip plastic plants to recover over time to be growing. After two weeks until the general shrinkage of notches, you can start the normal top dressing fertilizer in order to keep pumping raw sprouts, flowering after another. In order to avoid over-excessive growth, topping can be prompted multiple collateral more flowers.

(1) watering too much or exposed to rain, the long-term basin water, causing rot, yellow leaf edges or leggy plants are affected flowering.

(2) excess fertilization, especially nitrogen excess, can lead to leggy branches and leaves, not flowers or sparse flowering, flower quality poor. However, lack of fertilizer or no fertilizer, will also affect the normal growth and flowering plants. Thus, in early spring or early fall, more facilities should be more appropriate scale potash fertilizer.

(3) temperature is too high or too low, the winter temperature above 20 ℃, coupled with poor ventilation, easy to leggy branches and leaves, flowering of the following year, but winter temperatures below 0 ℃, are vulnerable to damage, yellow leaf margin weak. Geranium is also more sensitive to the temperature changes, such as rapid changes will cause the flowers fall off.

(4) is too light, exposed to direct sunlight in summer, margin vulnerable to sunburn, poor growth or flowers, leaves fall off.

(5) topping trim heavy, long-term leaves very little will also slow growth period, the flowers, blooming small number. In addition, winter and spring indoor conservation, if the long-term low-light, easy to cause excessive growth rather than flowering plants, and even the formation of flower buds has also shrunk due to lack of light dry. Therefore, the winter should give more attention to adequate lighting.
