Characteristics of roses
A rose is a woody, branched plant. A rose’s stem and branches have many rickles.
Roses have many different colors and sizes. A rose flower has many wings. The rose petals are curled, arranged in a number of circles around a pointed cone shaped like a round tear in the middle, squeezed or loosely depending on the type.
Roses are hermaphrodite. The male and female stamens are present on a flower, the stamens stick together and surround the ovary. When pollen matures, it falls onto the pistil and can pollinate on its own.
Roses have a slight fragrance, the petals are soft, easily crushed. Each rose may have one flower color, but sometimes there may be two colors on the same rose.
Roses planting technique
– Choose a pot
You should choose pots that match the age and size of the rose. If it is a mature rose, with large stalk, which needs a lot of water, then growing the rose in a large pot will help retain moisture. If you only want to plant new cuttings, which are weak, you should choose a small pot, to keep the pot dry. Large pots will make the roots of new cuttings rot.
At the same time, when choosing pots, pay attention to the drainage hole because the rose cannot stand waterlogged. Choose a pot with 2 holes or 1 large hole.
Roses can grow on many different types of soil. However, if you want the flowers to bloom, you should be able to grow sumptuous branches, so choose loose soil and put the pot where there is lots of sunshine.
To get this kind of soil, you can buy available soil at a shop or mix soil with decomposed cow dung, chicken manure, vermin manure, coconut fiber, peat, rice husks, organic humus, etc. Don’t forget to get rid of pathogens in the soil by applying lime, 7-10 days in advance.
– Detailed planting method
If you want to plant bare-rooted plants, soak them in a bucket of water for a few hours before planting.
When planting, put a layer of charcoal and a layer of coir at the bottom of the pot to help create ventilation, faster drainage, while the coir layer helps to keep some of the water in the pot in case of hot days.
Mix the soil with fertilizer (1/4 compared to the soil).
Press tightly the first layer of soil in the pot, then fill the pot with soil. Make a wide and deep hole, plant the rose and then continue to cover the roots with soil. The soil is about 4-5 cm from the top of the pot.
After planting, you can apply additional root stimulant. Water the soil and then wait a few weeks for the soil to dry before watering it again, because if the soil is too wet, the roots won’t be able to grow.
How to take care of roses
If the roses you grow is in the garden, it should be watered once a day; Water 2 times in the early morning and late afternoon if you plant roses in pots.
Water the roses thoroughly when it is dry. If lack of water, spiders will appear and harm your roses. Avoid watering your rose in the evening, because if the leaves stay wet at night, it will make the leaves more susceptible to fungus.

After about 3-5 months of planting, most roses will have pale yellow leaves, withered leaves. This is a sign that the soil has run out of nutrients. At this time, you need to replace the new soil.
When changing the soil, the rose will grow larger, so it is possible to also replace the pot to give the plant some space to grow. When replacing, it is advisable to combine pruning, remove yellowing leaves. After changing the soil and pot, the plants are weak, so it is often necessary to spray insecticide.
