brief introduction
Rose (scientific name: Rose) is native to China. It belongs to a deciduous shrub of Rosaceae, with many needles on its branches, odd pinnate compound leaves, 5-9 leaflets, oval shape and lateral thorns. Petals obovate, double to semi-double, purplish red and white. The fruit period is from August to September, and it is oblate. [1] The origin of roses is China. When roses are used as crops, their flowers are mainly used for eating and refining rose oil, which is used in cosmetics, food, fine chemicals and other industries.
In daily life, people refer to a series of cultivated varieties of Rosa as roses.
Growth habit
Roses like sunny, cold-resistant and drought-tolerant, and loose and fertile loam or light loam with good drainage. They don't grow well in clay loam, and they don't bloom well. It should be planted in a well-ventilated place away from the wall to prevent sunlight from reflecting, burning the bud and affecting flowering.
Can the newly transplanted potted rose seedlings bask in the sun? Newly transplanted potted rose seedlings can be exposed to the sun for 2-3 hours.
Rose is a temperate tree species, which is cold-resistant and drought-tolerant, and has no strict requirements on soil. It can grow in weak alkaline soil. It grows and blooms best in neutral or slightly acidic light loam rich in humus and well drained. It likes the light best, grows poorly under the shade, has few flowers, is intolerant of stagnant water, and leaves in the lower part will turn yellow when waterlogged, with strong germination and fast growth.
Rose is native to China and has a long history of cultivation. In plant taxonomy, rose is a shrub of Rosaceae. In daily life, it is a general term for a series of rose cultivars with large flowers, which can also be called roses or roses. Rose fruit is edible, sugar-free, and rich in vitamin C. It is often used in vanilla tea, jam, jelly, fruit juice and bread, as well as Nyponsoppa and Rhodomel. Roses have long symbolized beauty and love.
Where can I find potted rose seedlings in Shanghai? You're amazing.

I find it difficult to find real rose seedlings. .
Usually roses.
How to plant rose seedlings in flowerpots? First, the planting method of potted roses
1, with basin soil.
① Garbage soil 70%, river sand 30%.
② 60% dry river mud and 40% honeycomb cinder are mixed.
③ 70% of vegetable garden soil, 20% of honeycomb cinder and 0/0% of river sand/kloc.
2. Time of the basin. It should be done after defoliation in early winter or before germination in early spring.
3. Fertilize and water. Potted roses are controlled by limited pot soil, so the requirements for fertilizer and water are strict. ① A convenient and hygienic compound fertilizer is generally preferred, because compound fertilizer has many elements, and nitrogen, phosphorus and potassium are better combined. Apply about 20 grams per plant (the amount should not be too much), deepen the soil around the basin with iron about 10 cm, then apply fertilizer and cover the soil. (2) Watering is one of the basic tasks of flower cultivation, but it is often the reason why plants die easily. Water depends on the soil in the basin. Be sure to water it once when it is dry. Too wet can easily lead to rotten roots. Change the soil in the basin every other year, and cut off the roots around the basin bottom when changing the basin, so as to produce more flowers, bigger flowers and more colorful flowers.
4, plastic pruning
As usual, there is no need to prune, just prune the old plants with dense branches, withered branches and pests. Roses are in bloom. If they fail, pick them and bloom again, otherwise they will only bloom 1 time.
5, flowering control
As usual, natural flowering is better.
Leveling the land, choosing the land with deep soil layer, loose layout and good drainage to build the rose garden, with the pit spacing of 50 cm, the row spacing of 150-200 cm and the depth of 50 cm, and applying field manure or bio-organic fertilizer 10 kg to each pit.
Choose robust rose seedlings with 2-3 branches; Grafted seedlings require well-developed roots, 3-4 mm thick stems and 30 cm high plants. They should be planted with the seeds, and the seedlings transported to other places should be dipped in pulp and packaged.
Fair and close planting requires about 700 rose seedlings per mu. Because there were few seedlings in that year, in order to save land, we can plant 1500-2000 plants per mu. In the second year, seedlings can be transplanted or sold, and spring seeds can be planted in the early spring before the roses germinate. Autumn planting is from June 10 to February 12, and summer planting is carried out in rainy days.
Scientifically deal with intertillage weeding, because the seedlings are small and weeds are easy to grow, it is necessary to weed in real time, so as not to hurt the seedlings and have no grass. The connected soil is loose. Fertilization is mainly based on organic fertilizer, and topdressing is carried out four times a year as usual. Pouring livestock manure water for the first time before and after Hanukkah Festival is called accelerating germination fertilizer, and watering is carried out in real time. In late April, apply human and animal manure for the second time before the flower bud is pregnant or before picking flowers to promote more and fuller flower buds; Apply bio-organic fertilizer in May, and apply overwintering fertilizer in late autumn and early winter to ensure the safe overwintering of seedlings. Flowering in June, after dormancy in winter, cut off rotten branches, diseased branches and twigs and grow new branches. Careful pest control should be carried out at all stages of field management.
6, pest control
The main pests of potted roses are green worms and scale insects. Green insects are easy to control, but once the scale insects attack, it is difficult to control, which will cause the whole plant to be infected by insects and lead to diseases. Therefore, the control of scale insects is the focus of domestic roses. To control scale insects, we should put roses in a well-ventilated and well-lit place, cut off many branches of roses, and keep a few main branches to ventilate the interior. Keep the soil moist, but don't accumulate water. When white spots are found on rose branches, they should be scraped off with bamboo pieces in time. If it is serious, cut off the whole branch or even all branches directly, combined with spraying scale killing drugs. Roses are not afraid of pruning. Here's how to prune roses. Pruning is very important for the growth and flowering of roses. Generally, when overwintering, all branches should be cut off at a height of about 10 cm to ensure a smooth overwintering. After beginning of spring, new buds germinate, select 2-3 new buds, and break off the rest by hand. When the new bud grows to about 10- 15 cm, pick the top by hand. After a few days, 2-3 new buds will grow on each branch, so that the whole rose plant is complete and compact, and water and fertilizer can be supplied to several branches in a centralized way. After flowering, you can cut off the flowering branches and grow new ones soon. If you want to spend a lot, leave fewer branches and remove more buds. If you want to spend more money, give it a few more times. Roses consume a lot of nutrients when they bloom, so they should be fertilized in time before and after pregnancy.
2. Maintenance of roses
1. Wrap with plastic film. After selecting satisfactory flowers, be sure to wrap them in bundles with plastic film to avoid losing water. Cut it as soon as possible after returning to China and insert it in water to extend the viewing period.
2. Glass vase, filled with about two thirds of water, with a little salt, cut off the lower part of each flower stem by about one centimeter. It is best to cut in a horseshoe shape, that is, diagonally, so that it can last for about a week.
3. Soak the flower roots in hot water 15 seconds, and then subtract the soaked part. A vase can last for a week.
4. Add 5% sugar and 50PPM silver nitrate to every liter of water in the bottle to make a bottle plug-in.
5. Packaged rose bunches usually contain water, just pour a bowl of water every day.
Can roses be fertilized during the flowering of bone? Answer: During the expansion of flower buds (flower bones), base fertilizer can be applied once, but the base fertilizer should be fully decomposed (or liquid fertilizer). In addition, the weather is hot now, the evaporation of water is large, and the amount of potted plants should be more, especially in the next night.
The most suitable planting time of potted rose seedlings is spring and autumn.
There is no strict restriction on the planting time of roses, which can be planted all year round, and the best time is spring and autumn.
Are rose seedlings afraid of freezing? Generally, it should not be lower than minus 18 degrees Celsius, and basically stop growing below 7 or 8 degrees Celsius, and some varieties are resistant to minus 3 or 40 degrees Celsius.
Potting technology of roses? Raising roses in family flowerpots mainly pays attention to preventing scale insects and overwintering pruning, and other aspects are the same as other flowers. The main pests of potted roses are green worms and scale insects. Green insects are easy to control, but once the scale insects attack, it is difficult to control, which will cause the whole plant to be infected by insects and lead to diseases.
