How to overwinter roses in pots
Potted roses can be grown in northern areas during the winter and overwinter indoors, or dig trenches and bury them 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 cm 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. Regardless of whether they are planted on the ground or in pots, 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℃.
Watering and fertilizing:
Apply an appropriate amount of organic fertilizer into the tree hole before planting the roses, and water them thoroughly after planting. Ground-grown 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 fertilize 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 to 15 days after harvest. Roses are drought-tolerant. Generally, they are not watered if they are planted on the ground. They are watered once every 20 to 30 days during hot summer or spring drought. 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.
Plastic trimming:
Generally, no pruning is required. Old plants can be pruned away from 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 their stems, bright color and long flowering period.
The management of roses in winter depends on the region. If it is in the north, the temperature in winter will be several degrees below zero or even more than ten degrees below zero, and the roses or roses will lose their leaves and go dormant. However, in the south, roses can still grow vigorously in winter and bloom very well. In the group of flower friends, there are often flower friends from the south who post photos of rose blooms in winter, but in the north it is freezing and snowy.
Winter maintenance of roses is mainly for flower lovers in the north. If you don’t have a greenhouse or sunroom, it is recommended to overwinter outdoors in winter and let it sleep normally. For areas in Henan and Shandong, roses or roses can overwinter normally in the open air, but in winter It is best to plant in a south-facing, sunny, and leeward location, otherwise the cold wind will dry out the rose or rose branches.
Some florists put roses or roses indoors in winter on an east-facing or south-facing balcony, which will get good light, but the roses will not grow well because if roses want to grow vigorously, the minimum temperature must be above 10 degrees Celsius, and It requires sufficient sunlight, at least 4-6 hours of light. This condition is difficult to achieve indoors, unless it is in a greenhouse. The main problem indoors is insufficient light and dry air, which will breed red spider mites. If you have raised roses indoors in winter, You will know that red spider mites are a real headache. Therefore, if you have a greenhouse or sunroom that can ensure better lighting and nighttime insulation conditions in winter, you can maintain them and bloom normally in winter. If you only place them on the balcony indoors , I still recommend letting it sleep normally outdoors, and it will bloom better the next spring.
The hottest, humid, and sultry period of the year is the dormant period for roses, so now roses are growing branches. Pruning can make them bloom more, because nutrients are supplied to the branches.
Today’s rose is from the balcony. The sunshine is very good. It can get sunshine every day. The temperature is not high. Except for rain, it is sprayed with water basically every day.
When planting roses, you must choose the right flowerpot. Gallon pots are the most suitable for growing roses. Do not use pots that are too deep, otherwise the roots will easily rot. The soil must be fertile and well-ventilated. My roses are grown in nutrient soil.
The variety of roses is also very important. My balcony party raises many varieties, and they are all easy to grow. However, red Lonza gems and orange Lonza gems are difficult to grow, and they are prone to black stems and yellow leaves.
If you have a terrace or yard at home, you can plant climbing roses, such as European roses. Most of my roses are grown on the ground. Roses grown on the ground grow better and bloom more.
Roses should be cut off in time after they bloom, otherwise they will consume nutrients. You can also apply fertilizer after they bloom, and spray some potassium dihydrogen phosphate to make them bloom more and more vividly.
