The rose is a widely known flower. It is not only beautiful but also carries good meaning, making it one of the favorite subjects of flower lovers. In daily life, many people want to grow a pot of roses at home, but they don't know how, so how do you grow roses? Soil is essential, and there are strict requirements for light, watering and so on.

1. How to grow roses: watering is key

No matter what kind of flower you grow at home, since the conditions are not as good as outdoors, creating a favorable growing environment is crucial if you want the flowers to grow well. So for how to grow roses, flower lovers need to start with soil, light, watering and fertilizing, meeting each requirement one by one in order to grow roses well. For the specific requirements, let's continue reading in the rose planting methods.

2. Planting methods for potted roses

1. Soil: loose and fertile

In the rose planting methods, soil is very important, though roses are not demanding about soil. Flower lovers only need to choose a good growing medium containing a certain amount of humus aggregate structure. Of course, if you want the roses to grow fast, it is best to choose loam that drains well and is loose and fertile.

2. Watering: don't water until dry

No matter what flower you grow, watering is essential, and for how to grow roses, watering is very key. It is understood that roses are xerophytes, so they are very afraid of waterlogging, but not watering them is also not an option, so flower lovers must strictly follow the principle: do not water until dry, and when you water, water thoroughly.

Note: In daily life, many flower lovers are not skilled at care but are very diligent with watering. However, watering roses frequently is not only not good but can also cause serious damage to their roots, and even death. So when watering roses, you must follow the principle mentioned above.

3. Light: must be sufficient

For how to grow roses, light is indispensable; after all, they need to carry out photosynthesis, and without light that is impossible. Moreover, roses are light-loving plants, so if they are potted at home, flower lovers need to regularly move them outdoors to supplement light.

Note: If light is lacking, rose growth will slow down, and over time yellow leaves, rotted leaves and rotted roots will appear, until death. Not only that, during the growing period, if light is less than 8 hours, roses may also grow leggy and fail to bloom.

4. Fertilizing: use a light fertilizer

If you want plants to grow well and fast, proper fertilizing is key. In the rose planting methods, fertilizing also has its particularities. Flower lovers need to apply 20-40 granules of compound fertilizer evenly about 1 cun of soil below the pot edge every 1-1.5 months, or water once or twice a month with fully fermented rice-washing water or other light liquid fertilizer.

Note: Although roses like fertilizer, too much fertilizer should not be applied, otherwise it will cause partial root rot and death. In addition, as long as the leaves are green, the flowers are bright and the growth state is good, flower lovers do not need to fertilize again.

5. Temperature and humidity

Besides the above points, for how to grow roses, temperature and humidity are also very important. On temperature: the most suitable temperature for roses is 20-30°C. It is worth mentioning that roses are cold-resistant and can survive at low temperatures of -25°C to -30°C. On humidity: there is usually no requirement, but during the flowering season, the air needs a certain level of humidity.

3. Notes on potted roses

In the rose planting methods above, the editor has already introduced several points that need attention, but besides those, there are two more points flower lovers need to note: 1 is pruning, 2 is pest and disease control. The notes on potted roses are as follows:

1. Proper pruning

If you want roses to grow fast and look good, proper pruning is very important. From late April to early May each year, flower lovers should cut off dead old branches or diseased branches and remove them from the pot. After young seedlings are planted in spring, the first and second batches of flower buds should all be removed to save nutrients and promote branch and stem growth. For large plants, cut off the spent flowers.

2. Pest and disease control

Besides pruning, pest and disease control is also something flower lovers need to pay attention to. In the process of growing roses, potted at home, they cannot escape the invasion of pests and diseases, so flower lovers should prepare in advance. As for the specific pest and disease control for roses, it was introduced earlier, so we won't say more here.

Teaching you how to grow roses: planting methods for potted roses

Roses are flowers that girls very much like to receive. They not only symbolize passionate love, but can also be very "practical": dried roses can be used to make tea and can also be used to make snacks. Below, the editor will introduce how to grow potted roses and the planting methods for potted roses.

1. Planting methods for potted roses

1. Preparation of potting soil. ① Mix 70% garbage soil and 30% river sand. ② Mix 60% dried river mud and 40% honeycomb coal cinders. ③ Mix 70% vegetable garden soil, 20% honeycomb coal cinders and 10% river sand.

2. Potting time. It is suitable to carry out after leaf fall in early winter or before bud break in early spring.

3. Fertilizing and watering. Because potted roses are controlled by limited potting soil, they have relatively strict requirements for fertilizer and water. ① Generally, the first choice is convenient and hygienic compound fertilizer, because compound fertilizer contains various elements with a good ratio of nitrogen, phosphorus and potassium. Apply about 20 grams per plant each time (the amount must not be too much). Use an iron tool to loosen the soil around the pot edge to a depth of about 10 cm, then apply the fertilizer and cover it with soil. ② Watering is one of the basic tasks of growing flowers, but it is often also the cause of easy plant death. Watering depends on the potting soil: water thoroughly once as soon as it is dry; if too wet, it easily causes root rot. The potting soil should be changed once every other year, and when changing the pot, cut off the encircling roots at the bottom of the pot, which can make the flowers more numerous, larger and more colorful.

4. Shaping and pruning

Generally no pruning is needed; for old plants, just trim away overly dense branches, faded branches and pest- or disease-damaged branches. When roses bloom, pick them as soon as they fade; they will bloom again after picking, otherwise they will bloom only once.

5. Flowering period control

Generally, the natural flowering period is best.

Level the land and choose a plot with deep soil, loose structure and good drainage to create a rose garden. Dig holes at a plant spacing of 50 cm and a row spacing of 150-200 cm, with a hole depth of 50 cm, and apply 10 kg of farmyard manure or biological organic fertilizer per hole.

Choose good seedlings. Select sturdy rose seedlings. Seedlings grown from sprouts should have 2-3 branches; grafted seedlings require well-developed rootstock roots, a stem thickness of 3-4 mm and a plant height of 30 cm. They should be planted as soon as they are dug up. Seedlings transported to other places should be coated with mud slurry and packaged.

Reasonable dense planting. According to requirements, about 700 rose seedlings are needed per mu. Because there are fewer seedlings that year, to save land, 1,500-2,000 can be densely planted per mu. In the second year, the seedlings can be transplanted or sold. Spring planting is carried out in early spring before roses sprout; autumn planting is carried out from October to December; summer planting is carried out during continuous rainy and cloudy days in the rainy season.

Scientific management. For intertillage and weeding, because the seedlings are small, weeds grow very easily, so weeding work must be done in a timely manner, ensuring that seedlings are not damaged and no weeds remain. Keep the soil loose. Fertilizing is mainly with organic fertilizer; generally topdress four times a year. Around Qingming Festival, apply human and livestock manure water for the first time, called bud-break fertilizer, and water in time; in late April, before budding or flower picking, apply human and livestock manure water for the second time to promote more and fuller flower buds; in May, topdress with biological organic fertilizer; in late autumn and early winter, apply wintering fertilizer to ensure the seedlings overwinter safely. After flowering in June and during the winter dormant period, cut off aged branches, pest- and disease-damaged branches and weak branches to encourage new branches. At every stage of field management, pay close attention to pest and disease control.

6. Pest and disease control

For potted roses, the main pests are caterpillars and scale insects. Caterpillars are easy to treat. Once scale insects break out, they are harder to control, will cause the whole plant to be infested and lead to disease, so controlling scale insects is the key point in home rose growing. To control scale insects, place the roses in a well-ventilated, sunny place, and cut away the numerous rose branches, keeping a few main branches so the interior is ventilated. Keep the potting soil moist, but do not let water accumulate. When white spots are found on rose branches, scrape them off promptly with a bamboo piece. If it is more serious, directly cut off the entire branch or even all branches, and combine this with spraying scale insecticide. Roses are not afraid of pruning; the pruning of roses will also be introduced below. For roses to grow well and bloom abundantly, pruning is very important. Generally when overwintering, cut off all branches about 10 cm above the ground so they overwinter smoothly. After spring begins, new buds sprout; choose and keep 2-3 new buds and pinch off the rest by hand. When the new buds grow to about 10-15 cm, pinch off the top by hand. After a few days, each branch will grow 2-3 new buds again. In this way, the overall rose plant shape becomes complete and compact, water and fertilizer can be concentrated to supply a few branches, the flowers bloom large, and the quantity can also follow your wishes. After blooming, you can cut off the flowered branches, and before long new flowering branches will grow again. If you want large flowers, keep fewer flowering branches and remove some extra flower buds; if you want more flowers, pinch the tops more times. Rose flowering consumes relatively more nutrients, so before budding and after flowering, roses must be fertilized in time.

2. Preservation of roses

1. Wrap with plastic film. After choosing satisfactory flower material, be sure to wrap it into bunches with plastic film to avoid water loss. After returning home, trim as soon as possible and place in water to extend the viewing period.

2. In a glass vase, put about two-thirds clean water, add a little salt, and cut off about one cm from the lower part of each flower stem. The cut is best made in a horseshoe shape, that is, an angled cut. This can keep them for about a week.

3. First soak the flower roots in hot water for 15 seconds, then cut off the soaked part. Place in a vase and they can be preserved for a week.

4. Add 5% white sugar and 50PPM silver nitrate per liter of water in the vase to make a vase solution.

5. For roses already packaged in bunches, the package generally contains moisture, so just keep sprinkling a bowl of clean water on them every day.

How to grow potted roses: cultivation methods for potted roses

Cultivation methods for potted roses in summer

Once the peak flowering period of potted roses has passed, they enter the hot and humid summer, and are mostly in a dormant or semi-dormant state. Strengthening summer management of potted roses and carrying out rejuvenation care can break the dormant period and keep them blooming continuously throughout the summer. The main management measures are:

1. Shade and ventilation. Potted roses have limited soil, and in high-temperature weather the soil easily heats up and dries out, so roses must be shaded and cooled. It is best to place the potted flowers from 8 a.m. to 4 p.m. in a ventilated spot under courtyard trees or a trellis, so the potted flowers receive scattered light and roses are given suitable environmental conditions for growth and flowering.

2. More fertilizer and water. Roses bloom many times and need sufficient nutrients and water to ensure vigorous growth. Entering summer, their evaporation and consumption are both high, and growth is rapid. During the flowering period, apply a thin fertilizer once every 10 days. You can also soak bean cake and poultry manure in water, and after sealed fermentation mix with water as a topdressing, so the plants have abundant flowers and leaves and the summer dormant state of roses is broken. For watering, it is best to use water that has been left in the sun to reduce the temperature difference between the potting soil and the water. If too cold water is used, it will stimulate the root system and affect the normal development of the plant.

3. Spray more water. Roses enter a semi-dormant state above 33°C, and are most favorable for growth at an average temperature of 20-25°C. Therefore, in summer, besides appropriate shading, more water should be sprayed, preferably once in the morning and once in the afternoon, creating a humid environment and promoting the growth of flowers and leaves.

4. Thinning branches and pruning. After roses bloom, they should be cut below the third compound leaf under the flower to promote strong new branches and early budding and flowering. Weak short branches should be cut first and cut high; vigorous branches should be cut later and cut short, so as to promote the weak and suppress the strong, and promote uniform flowering. The pruning length of long branches should not exceed one half, to avoid delayed axillary bud sprouting. In addition, too many flowers should not be kept per flush; for potted roses, 3-5 flowers are appropriate. If too many flowers are kept, nutrients are too dispersed, the flowers are small and the next flush of flowers is affected.

5. Loosen soil and weed. Along with clearing weeds on the pot surface, you can use a fine wire rake to gently break the surface layer around the flower pot, enhancing the looseness and aeration of the potting soil and promoting normal root growth.

6. Prevent and control pests and diseases. The place where flower pots are placed should often be sprayed with 15% quicklime water or carbendazim or potassium permanganate aqueous solution for sterilization. In the rainy season of July-August, high temperature is a high-incidence period for leaf spot and powdery mildew. Spray with 0.3-0.5 degree Baume lime sulfur mixture once a week, for a total of 2-3 sprays. From June to July, if longhorn beetle larvae are found causing damage, the branch tips should be cut off immediately. If other leaf-eating pests are found, immediately spray 800-times monocrotophos for control, which can kill eggs and larvae.

How to grow potted roses

For potted roses in northern China in winter, overwinter indoors, or dig a trench and bury the pot to overwinter. Planting can be done from after leaf fall in autumn to before bud break in spring. Choose a place with higher terrain, facing the sun and without water accumulation. The planting depth should be 15 cm from the roots to the ground. For potting, use a growing medium mixed with leaf mold, garden soil and river sand, and add an appropriate amount of decomposed barnyard manure or cake fertilizer and compound fertilizer. After planting, water thoroughly once, place in a shaded place for several days to let the seedlings recover, then move to sunlight for cultivation.

Light and temperature: sufficient sunlight promotes good growth. Whether planted in the ground or in pots, roses should be placed in a sunny place and receive more than 4 hours of direct sunlight every day. They cannot be placed for a long time indoors in a place with insufficient light. In winter, bring them indoors and place them in a sunny spot. The suitable growth temperature is 12-28°C, and they can tolerate a low temperature of -20°C. In the Zhengzhou area, they can overwinter safely in the open field.

Watering and fertilizing: Before planting roses, apply an appropriate amount of organic fertilizer in the tree hole, and water thoroughly after planting. Ground-planted roses are not strict about water and fertilizer; generally 3 fertilizations are enough. The first is pre-flowering fertilizer, applied in furrows before spring buds sprout, preferably decomposed barnyard manure plus leaf mold. The second is post-flowering fertilizer; after the flowers fade, apply decomposed cake fertilizer residue to supplement the nutrients consumed by flowering. The third is winter fertilizer; after leaf fall, apply barnyard manure to ensure roses overwinter safely. Potted roses can be given dilute fertilizer water during the growing period, once every 10-15 days. Roses are drought-tolerant. Generally, ground-planted ones are not watered at ordinary times; in hot summer or spring drought, water once every 20-30 days. Potted ones are watered once every 2 days, and once a day in hot summer or spring drought. Spray with Xinguo lipid film to retain fertilizer and moisture.

Shaping and pruning: Generally no pruning is needed; for old plants, just trim away overly dense branches, dried branches and pest- or disease-damaged branches. When roses bloom, pick them as soon as they fade; they will bloom again after picking, otherwise they will bloom only once.

Flowering period control: Generally, the natural flowering period is best. Spray flower-strengthening agent at the bud stage for vivid color and a long flowering period.

How to grow potted roses and the cultivation methods for potted roses have been introduced here. We hope it is helpful to everyone. When roses are used as an agricultural crop, their flowers are mainly used for food and for extracting rose essential oil. Rose oil is used in cosmetics, food, fine chemicals and other industries.
