Spring is the most suitable time for planting roses. Roses generally bloom from May to June, so it is best to plant them in March.

Rose likes light and sunshine, and is resistant to severe cold and drought. In the northern winter, it does not require special protection and anti-freeze. As long as there is no severe drought, it can grow without watering (referring to ground planting). The soil requirements are not strict. Generally, fertile soil can achieve vigorous growth, luxuriant leaves, and good flowering if managed properly.

Rose should be planted in fertile loam soil in fields and fields with good ventilation, sunshine, watering and good drainage. Before planting, apply an appropriate amount of organic fertilizer into the tree hole and water it thoroughly after planting. Ground-grown roses do not have strict requirements for water and fertilizer. Water and fertilize reasonably according to the needs of the plants, and spray new high-fat film to maintain fertilizer and moisture.

Fertilizer should be applied frequently in summer, once every 15 to 20 days. Water should be watered in time after fertilization to prevent seedlings from burning. Spraying Flower Stabilizer during the flower bud stage can promote strong flower buds, enlarged petals, bright colors, rich floral fragrance, and prolonged flowering period. Prune in autumn to prevent excessive growth and affect flowering and plant shape. Roses are prone to aphids, so be careful to control them. During the hibernation period, you can apply base fertilizer and fill with overwintering water to lay the foundation for stable and high yield of flower buds in the coming year.

Planting roses

Mainly on the ground, there are also a small number of potted plants. In the Yellow River Basin and areas south of it, it can be grown on the ground and overwintered in the open. In cold northern areas, it should be potted and overwintered indoors, or trenches should be dug and buried in pots to overwinter. It can be planted after the leaves fall in autumn and before budding in spring. It should be planted in a higher, sunny place without water accumulation. The appropriate depth should be 15 centimeters from the root to the ground. When potting, use a culture soil mixed with leaf mold soil, garden soil, and river sand, and add an appropriate amount of decomposed manure, cake fertilizer, and compound fertilizer. After planting, water the seedlings once thoroughly, place them in a shaded place to slow down the seedlings for a few days, and then move them to the sun for cultivation.

Light and temperature

Sufficient sunlight promotes good growth. Whether ground plants or potted plants, they should be placed in a sunny place and receive more than 4 hours of direct sunlight every day. It cannot be placed indoors in a place with insufficient light for a long time. Enter the house in winter and place it in a sunny place. The suitable growth temperature is 12-28℃, and it can withstand low temperatures of -20℃. It is safe to overwinter in the open field in Zhengzhou area.

Watering and fertilizing

Apply an appropriate amount of organic fertilizer into the tree hole before planting, and water it thoroughly after planting. Ground-planted roses do not have strict requirements for water and fertilizer. Generally, three times of fertilizer is sufficient. The first is pre-flowering fertilizer, which should be applied in the ditch before the spring buds emerge. It is better to use decomposed manure and leaf mold soil. The second is post-flowering fertilizer. Apply decomposed cake fertilizer residue after the flowers fade to supplement the nutrients consumed by flowering. The third is to apply fertilizer in winter and apply manure after the leaves fall to ensure that the roses survive the winter safely. Potted roses can be fertilized with thin fertilizer and water for a long time, once every 10-15 days after harvest. Roses are drought-tolerant. Generally, those grown on the ground do not need to be watered. During hot summer or spring drought, they need to be watered once every 20-30 days. Water potted plants once every two days, and once a day during hot summer or spring drought. Spray the new high-fat film to maintain fertilizer and moisture.

Pruning

Generally no pruning is required. Old plants can be pruned to remove dense branches, dry branches, and diseased and insect-infested branches. Roses bloom, pick them as they bloom and fall, and bloom again after picking, otherwise they will only bloom once.

Flowering period control

Generally, the natural flowering period is better. Spray the flowers during the bud stage to strengthen the stems, bright color and long flowering period.

To plant roses, you only need to do the following:

A) Sunlight: Roses like the sun and fear the shade. If they are planted in a place with weak light for a long time, they will grow Poor or rotten roots will die (no photosynthesis to produce growth nutrients, no evaporation leading to no physiological cycle, resulting in wilted buds, fallen leaves or rotten roots), so it should be planted on a sunny balcony or windowsill.

When flowers bloom, bring them indoors to appreciate them. After the flowers fade, they should be brought to a sunny place for cultivation.

B) Watering: Roses are most afraid of watering every day. Overwatering is like heavy rain every day for a long time in nature (like pickles), which causes root rot. When the roots of the plant are rotten, they will lose the ability to absorb nutrients and The function of water will cause buds to drop, leaves to fall or die.

When watering, we must grasp the basic principles of "don't water if it's dry, water thoroughly" and "don't water on rainy days".

When flowers bloom, bring them indoors to enjoy the flowers. The soil in the pots should be moist. Do not water them indoors.

C) Fertilization: Some friends who are new to planting think that the more fertilizer they apply, the better they will grow. They even bury large amounts of nitrogenous fertilizers and compound fertilizers at the main roots of the plants (or mix them with very concentrated chemical fertilizer water or Directly using urine for watering) will cause burned roots and dead plants (inorganic salt reverse osmosis), because plants only like light and thin fertilizers. Applying fertilizer too thickly and too frequently will cause local root damage, resulting in curled and uneven leaves, yellow leaves, fallen leaves and Root rot dies. As long as the flowers are bright and the leaves are green, there is no need to fertilize frequently.

It is recommended to pour the rice water, noodle soup, and dumpling soup into the mixing oil barrel. After it is fully fermented, it will become excellent light fertilizer water (it has a small smell and will not burn the roots, suitable for household potted plants as top dressing). It is best to apply compound fertilizer 3-4 times during the growth period, and apply 20-40 grains each time evenly under an inch of soil around the pot soil (chemical fertilizers take 20-30 days to decompose before they can be absorbed by the plants).

D) For potted xerophytic woody flowers such as roses, jasmine, gardenia, peony, peony and rose, unglazed clay pots of suitable size and water permeability should be used. The culture soil should be rich in humus pellets. Well structured soil.
