What season are roses suitable for planting?
Spring and autumn are fine,
In spring, plants are full of vitality and easy to survive.
It is best to plant in autumn and bloom in spring after winter.
It can't be planted in winter, and it is dormant, so it is easy to die if you move.
You can barely plant in summer, but you should pay attention to shading and watering, and you can grow well with careful maintenance.
When is the best time to plant roses?
Spring is the best, in fact, the key is survival. It is certainly good to survive if you plant in autumn, but the chances of survival in summer and winter are much lower.
What season are roses suitable for?
Cultivation method: (1) adopts branching method, which can be carried out in spring or autumn. Choose rose plants that grow vigorously, dig them up one by one, and plant them from the roots according to the growth trend of the roots. It usually breeds once every 3-4 years. (2) Cutting method can be used in spring and summer. Generally, before the plants germinate in February and March, 2-year-old robust branches are selected and cut into 6540 pieces. Stick it in the bed. Cuttings are usually carried out in July and August, and annual shoots are selected as cuttings to be inserted into the seedbed. Generally, cuttings can take root in about a month, and then transplant and maintain them in time. Cutting can also be carried out when pruning plants in winter from June to February in 5438. Temperature: the suitable growth temperature is 15 ~ 20℃. Strong cold resistance. It won't be frostbitten if it drops to MINUS 20 degrees in winter. Therefore, roses can safely overwinter on the land in northern China. Soil: Suitable for sandy loam with deep soil layer, fertile soil and good drainage performance. Moisture-proof: resistant to drought and afraid of excessive humidity. If planted in low-lying, high groundwater level and poor drainage, it will easily lead to rotten roots, fallen leaves and even death. Sunshine: sunny and semi-cloudy.
The best season to plant roses
Generally, planting roses starts from small seedlings or medium seedlings. In a year, except summer, it is not suitable, and other seasons have to be planted or changed. Choose loose, well ventilated and well drained culture soil for planting. Before planting, apply oil meal, bone meal and multifunctional active organic fertilizer to the culture soil. After planting, it is necessary to apply accelerator to improve vitality.
When is the best time to plant roses?
1 1- 12 years after defoliation, or when buds just germinate in early March and April, each cluster should be equipped with 2-3 branches, and the fibrous roots should be dipped in mud to share the load, and cut off from 25-35 cm above the soil surface to promote the emergence of new branches. You can also press the branches near the ground into the soil in May-June, and cut the buried parts, which can take root after 2-3 months, and can be loaded separately from the mother plant. Before loading, decomposed organic fertilizer should be used as base fertilizer, and after loading, water should be poured. Roses are fond of fertilizer, and they are applied four times a year (accelerating germination in early spring, accelerating flowers in May, supplementing fertilizer at flowering stage and entering winter). Roses are afraid of waterlogging, so don't water them too much. Regular pruning can make plants grow vigorously and flowers flourish. Pay attention to disease prevention.
It is better to cut in autumn, but it is certainly better to plant it directly in spring.
When is the best time to plant roses?
If you grow your own ingots, you can use them in spring, summer, autumn and winter. Pay attention to temperature, humidity and light. It is best to choose late spring, early summer and early autumn.
Cutting is simple and easy.
When should roses be planted?
Generally, it is better to plant in spring, and the seeds harvested in autumn need to be stored in sand for two or three months in wet seeds at about 5℃ to mature, otherwise they will not germinate. Soaking seeds before sowing can promote seed germination.
Planting roses with seeds is not recommended. The variability of seed planting is very large. More than 99% of them will return to their ancestors and become single-petaled flowers, and only about one in ten thousand will present excellent varieties. Only by cultivating new varieties will seed propagation be adopted, and only large plantations will spend a lot of energy and material resources to do this. Family farming is still recommended to propagate by cutting, grafting or layering.
When are the roses planted?
Roses like sunshine, are cold-resistant, drought-resistant and waterlogging-resistant. The soil requirement is not strict, but it grows well in fertile neutral or slightly acidic sandy loam with good drainage. Roses flourish and are easy to manage. In spring, dilute human and animal urine is poured around the roots, in summer, attention is paid to watering and drainage, and some fertilizers are applied around the roots in autumn. Propagation is mainly carried out by dividing plants, which can be carried out before germination in March or after defoliation in autumn. The rootstock of layering method or grafting method can be Chinese rose or Chinese rose. The survival rate of cutting is not high, and it is only used occasionally. Single rose can also be planted and propagated in spring or autumn. in addition
Winter and spring alternate stages (during the Chinese New Year), because the weather is no longer so cold; Suitable for crop growth, moist air, and seeds are easy to germinate and survive. Roses are generally planted by cutting and grafting. Although you can sow seeds, I'm afraid your skills are not good. Roses can be planted all year round, but April and May and September 65438+ October are the keys to control temperature and humidity and prevent diseases and pests.
Selection method of good seedlings: among Chinese rose seedlings, there are "big seedlings" listed in winter and "new seedlings" only available in spring. For beginners, it will not fail to plant from big seedlings, so "big seedlings" are recommended to beginners. Make sure the following points when buying big seedlings: 1, 2-3 branches thicker than pencils. 2. The color of the branches should be slightly brown and shiny. 3, try to touch the branches, to feel strong. 4. Branches and roots are not infected with diseases. Avoid the following flower seedlings: all young twigs, flowers with dull green branches, flowers with loose and soft feelings in the middle. In addition, flower roots can be infected with diseases. It is also important to carefully confirm whether there is tumor in the root, complete the label and clearly indicate the variety name. Cultivation place: Roses like a cool and sunny environment, and they need at least 6 hours of sunshine every day to produce good quality flowers. Its suitable growth temperature is 15-25℃, which is too high for the growth of roses. Besides, good ventilation is also important. The hot, humid and poorly ventilated environment is easy to make rose plants suffer from various diseases, such as black spot and powdery mildew. At present, there are generally two kinds of cultivation places: gardens and balconies. Gardens are generally planted in sunny places, with at least 2-5 hours of sunshine throughout the morning; Choose a place with good drainage and ventilation; Mix thoroughly with humus or compost before transplanting. Balcony generally takes effective drying measures; Lay curtains, don't put the flowerpot directly on the concrete; In order to prevent the drainage ditch from blocking or leaking, we should also consider living nearby; Leave it in a sunny place for 2-5 hours in the morning. Soil: The soil suitable for the growth of roses must have three main points: looseness, good ventilation and good drainage. Potted soil can be made of sandy loam, snake sawdust and vermiculite, while roses cultivated in the open field must be planted where there is no water, and the soil should be turned loose before planting. For garden planting, in order to improve the state of garden soil during transplanting, pits are dug in some transplanted places to remove bad soil, and ruby, humus soil, dried cow dung and other substances with granular structure are mixed in the dug places. In places where roses have been planted before, transplanting new roses may worsen the growth and development of roses. In this case, new soil should be replaced. The flowerpot should be planted with red soil mixed with humus and dried cow dung. The proportion of mixed soil is as follows: red loam 60%, humus 20% and dry cow dung 20%. It is easy to use commercially available rose culture soil. You can also use it directly. In order to further improve courage and drainage, if water conservation is mixed with 20-30% ruby soil, the soil can be used to achieve the best state. Seedling transplantation: it can be divided into garden transplantation and planting box (flowerpot) transplantation. The key point of garden transplanting is that the flower roots spread evenly around. In addition, when transplanting, never fertilize the soil. After transplanting, the plants should be fully watered, and before the roots are firmly rooted, columns should be erected to support the plants. Preparation supplies include buckets, plastic gloves, leather gloves, pruning shears, posts, strings, name tags, small shovels, humus (or compost), shovels, etc. The main steps are as follows: 1. Remove the film covering the roots. The flower roots are protected by protective materials, such as sphagnum or peat. 2. Carefully remove the protective materials and soil, and perform the operation under the condition of carefully confirming that there is no tumor at the root. Trim about 1/3 of the roots. 3. Put the flower roots into a bucket filled with water, and let the roots fully absorb water for 30 minutes-1 hour, but be careful not to let go. ......
When is the best time to plant roses?
Rose originated in northern China and has a long history of cultivation. Many countries and nations in the world regard it as a symbol of good things. Europeans and Americans use it to express their love. Bulgaria regards it as the national flower, which symbolizes hard work, wisdom and courage. Roses like sunshine, and they will grow strong when they are suitable for soil and climate. It can be planted in barren hills and slopes and scattered miscellaneous land, and the requirements are not strict. They can resist cold and drought, but they can also resist waterlogging. Under the conditions of mild climate, moist soil and abundant rainfall, it grows luxuriantly. Generally, old branches germinate in early March, spread their leaves in early April, germinate in mid-April, and bloom in May-June, with a flowering period of about 20 days. Leaves die after light snow, and the growth cycle is 9 months.
Roses are widely planted in our country, forming many centers rich in roses. There are thousands of acres of rose gardens on Miaofeng Mountain in Mentougou, Beijing. Kushuichuan in Lanzhou, Gansu Province is the hometown of red roses on the Loess Plateau in western China. Roses produced in Pingyin County, Shandong Province, with large color, thick petals and strong fragrance, have always been among the best in the world. Roses have many uses. Plants not only have high ornamental value, but also can be used for water and soil conservation on hedgerows or hillsides. Flowers are widely used, such as rose cake, rose dew, rose wine, rose sauce and rose tea, which are widely welcomed by the market. Rose oil is expensive and is an important raw material for perfume industry and pharmaceutical industry. 1 kg is equivalent to 1.52 kg of gold, so roses are also called "golden flowers". As early as the ninth century, India knew how to use roses; Bulgaria began to extract rose oil from rectification tower in16th century, and now it has become the largest producer of rose oil in the world, with an annual output of 2000 kg. The fragrance of rose oil is very strong, and two drops can be made into a fine perfume of 1 liter. The oil yield of roses is about four ten thousandths. To extract 1 kg rose oil, 2-3 tons of rose petals are needed, equivalent to 20,000 or 30,000 roses, and the planting area is 1.5 hectares (that is, more than 22 mu of land). Roses are edible ingredients of candied fruit, cakes and other foods. The simple processing method is to spread the flowers on the table to dissipate heat, rub off the calyx, stamen and stalk, discard them with a dustpan, put the pure petals in the laundry basket, rub them with sugar, add 1 kg sugar to each catty of flowers, knead them into balls, and put them in the basket and seal them with paper as a seasoning for making cakes. It can be used to smoke tea and make wine, or it can be mashed with frosted flowers and dark plums to make rose sauce. After exposure, you can put it in a magnetic bottle and use it at will. Can also be wrapped in textiles as fan pendants, sachets and so on. The effect is better than other flowers.
Because it is easy to grow red roses, a young farmer planted 6000 plants with only five acres of barren hills. In eight months, he collected 600 Jin of flowers and 800 Jin of seeds, and his net income was more than 1 100 yuan. If we can expand the planting area or process rose products ourselves, its economic benefits will be high.
Red roses can be planted singly or interplanted, suitable for barren hills and slopes and scattered fields. If there is no special land, they can be interplanted with orchards or cash crops with short growth period. After loosening the whole field, only one field should be dug. The size of the cave is 8 inches square, and the cave surface is off the ground 1 inch. Row spacing per plant 1 m is enough. Agree to plant 120 plants per mu. Generally in late April (between Grain Rain and Changchun), seeds with full seeds and no pests should be directly sown. Before sowing, put half a handful of calcium superphosphate and appropriate amount of soil in each hole. Finally, there were/kloc-0 seedlings per hole, and the seedlings propagated well. Some people say that the cuttings of roses are lifeless, but in fact they can survive, so cuttings can also be used to breed roses. "Reading Mirror" noticed that every time a new rose was painted, its roots would wither easily, so it was necessary to transplant the twigs near the roots quickly, and then its roots would remain the same, so it was commonly called "leaving the mother grass". In most places, the method of dividing plants is used for propagation, generally during the dormant period (from defoliation to germination), both in spring and autumn. The method is to dig out the whole plant first, mix the plants scattered in the soil together, then cut off a branch, remove the old roots and plant it alone, or keep the mother plant still, cut off the new plant and plant it alone, which is very simple.
Red roses should be fertilized immediately after thinning. I applied water fertilizer, plant ash and other miscellaneous soil fertilizers, and dug ditches to cover them when fertilizing in sunny days. If it is better to apply chemical fertilizer in rainy days, you can spray 5 kg of ammonium bicarbonate and water per mu. At the same time, intertillage weeding must be completed before the heat, and then weeds should be pulled out. Before budding, flowers should be sprayed with 10 kg urea or compound fertilizer per mu in time after rain. Roses are naturally fat, and if they are not fat enough, they won't bloom much. Overwintering fertilizer and petal fertilizer are essential, and the principle of light application should be implemented on weekdays to maintain vigorous growth.
Red roses have strong disease resistance and few diseases and insect pests occur. Once it happens, each mu can be sprayed with 1 dichlorvos or thiophanate-methyl mixed with water. For example, pests can spray a proper amount of music, and diseases can spray a proper amount of amobam or new mold. ......
How to plant roses! When is the best time to plant?
(1) selecting complete disease-free branches:
Cutting with healthy and robust branches, "a good beginning is half the battle", select the mother plant with strong growth and no pests and diseases, cut off the top inflorescence to promote its tissue enrichment, and cut after one week.
(2) pest control:
Diseases such as black mold and branch blight should be avoided in cutting substrate, pot soil or cutting environment, so it is very necessary to use fungicides correctly.
(3) Cutting and water management:
Home cutting can be heated and humidified in a cutting bed covered with plastic film. When it germinates, the plastic film cover is removed, and seedlings can be transplanted and planted after 4-5 days.
The cutting survival rate is the highest in the mixed substrate of peat and perlite (5: 1). First, spray 800 times of thiophanate methyl solution to disinfect the substrate, then put the substrate into a flat seedling tray (about 5 cm deep), smooth it, gently compact it, spray clean water, and soak the substrate about 2/3 deep for later use. Cut the cuttings to a length of about 5-7 cm, and cut the upper end horizontally, and the cutting mouth is about 1 cm from the terminal bud. The lower end is obliquely cut into horse ears, leaving only 2-3 compound leaves on the upper part for wound healing and rooting. Soak the cut cuttings in 0.3% potassium permanganate solution for 5 seconds, and then soak the lower end in ABT2 rooting powder solution for 20 minutes. Insert the cuttings into the prepared substrate, with leaves exposed, and the spacing between plants is 5-7 cm. Compacting the matrix around the chips so that the chips are in close contact with the matrix.
(4) Planting
Generally,/kloc-0 is planted twice a year, 1 time is before germination in spring, and the second time is planting with green cuttings in August. Organic fertilizer and phosphate fertilizer are used as base fertilizer before planting. Water it twice in time to ensure survival.
(5) Other precautions:
1 The middle section of cut flowers is more suitable for cutting.
The cutting substrate can be mixed with peat soil and pearl clay. (available at the flower market)
In order to promote axillary bud germination of cuttings, nutrients containing BA can be added or refrigerated to break the dormancy of axillary buds.
It takes about one month to raise seedlings in summer and 50-60 days to raise seedlings in winter.
Cuttings in spring tend to grow axillary buds before rooting, which affects their survival rate.
6. The hotbed treatment can promote the rooting of cuttings in winter and improve the propagation speed.
Spray a little water after insertion and put it into the small arch shed in time. Callus can be produced in 10- 15 days, and the rooting rate is over 90%. At this time, we should pay attention to the temperature and humidity changes in the shed, keep the temperature at 15-25℃, and spray water every 5-7 days, preferably in the early morning. After sprouting and growing leaves, combine with deciduous leaves for disinfection. Small arch sheds should be kept fresh in time, and air circulation should be maintained, and the specific situation should be flexibly grasped. After rooting, gradually uncover the film and harden the seedlings. When the seedlings adapt to the external environment, remove the small arch shed. When the seedlings grow to 5-7 cm, they can be transplanted into a small nutrition pot of 99 mm, and then gradually changed into a large pot with the growth of the seedlings.
The best season for cutting roses at home is summer and winter. Summer lasts more than 65,438+0 months, and winter takes a long time. The best method of home cutting is to soak the branches of roses in water and let them sprout. If possible, you can get a pool at home, fill it with sand, and insert the branches of roses in the sand, but when choosing branches, you should grasp the bud eyes and don't cut them off.
