How to cultivate roses and precautions
You may not be familiar with the cultivation methods and precautions for roses and the correct watering methods for green plants and flower planting. Let's learn about them together below.
Known as the "Queen of Flowers," roses are loved by many for their noble and dignified temperament, fragrant blooms, and graceful posture. In recent years, with the emergence of improved rose trees, planting rose trees in the courtyard has become a vibrant and elegant addition, showcasing the owner's grandeur and romance; the beautiful and unique small potted roses are used to decorate living rooms, studies, bedrooms, and living spaces, highlighting their charming and elegant beauty.
Roses have a blooming period of over 180 days, also known as "monthly red." Roses have the effect of activating blood and regulating menstruation, soothing the liver and resolving depression. Keeping a pot of roses at home not only allows you to enjoy the fragrance for over 180 days a year but also beautifies the living environment and purifies the air, making it a flower variety that combines practicality and ornamental value. So, how exactly do you care for potted roses? What issues should be considered during the maintenance process? Today, we share five rose cultivation methods.
1. Requirements for temperature and sunlight. The most suitable temperature for rose growth is between 15 to 28 degrees Celsius. If the temperature exceeds 30 degrees Celsius in summer, roses will bloom less, the flowers will become smaller and of lower quality, and many pom-pom type flowers will turn into large flat shapes. If the temperature drops below 5 degrees Celsius in winter, roses will enter a dormant state. Roses prefer a warm and sunny growing environment, so they need at least 6 hours of sunlight daily. The more sunlight they get, the more vigorous the growth and the more vibrant the flower colors, with a stronger fragrance that can be smelled from afar. However, excessive exposure in summer can scorch the petals, causing the edges to wither and turn brown, so proper shading should be done around noon in summer.
2. Selection of soil and pots. Roses prefer rich organic, loose, breathable, and well-drained slightly acidic soil. They dislike alkaline and heavy clay soil, which can lead to severe compaction and directly hinder the rose's absorption of water, causing dryness and wilt. For planting roses, it is best to choose a clay pot with good breathability and water permeability, or a wooden barrel can also be used. Before use, clean and disinfect to prevent infections and parasites from invading the plant. Large potted roses can use pots with a diameter of 30 to 50 centimeters; mini potted roses can use pots with a diameter of 15 to 20 centimeters.
3. How to water and fertilize. Roses prefer moist soil and are somewhat drought-tolerant. During the growing period, water when the soil is dry and water thoroughly. Water in the morning in spring; in summer, water in the morning and evening; and in autumn and winter, water in the morning. newly planted roses should be watered thoroughly, and after a week, water can be given again. During the growing season, fertilize every 15 days or so, combining it with watering, usually using a matured compound liquid fertilizer of nitrogen, phosphorus, and potassium at a ratio of 1:800 to ensure plant growth and leaf color. Increase the application of phosphorus and potassium fertilizers before flowering, using a spray bottle to apply foliar fertilizer or pour it at the roots.
4. What to do after flowering. After the rose has finished blooming, cut off the section from the flower to the third leaf with scissors to promote the growth of new branches and reblooming. Each time the rose blooms, control the number of flowers. For single-head potted roses, keep 3 to 5 flowers per pot; for multi-head potted roses, keep about 3 flowers per head. Too many flowers can cause the nutrients to be scattered, resulting in smaller flowers, dull color, and affecting the next blooming.

5. How to prevent and control pest and disease infestations. Common rose problems include black spot, powdery mildew, red spider mites, and aphids. Roses are prone to diseases and should be sprayed regularly for prevention during growth and flowering. Before spring blooming, spray roses with carbendazim or benomyl to prevent powdery mildew; after summer rain, spray to prevent black spot; in winter, after defoliation, spray lime sulfur to kill pests, reducing the occurrence of diseases and pests the following year.
6. How to choose roses. When roses are in full bloom, many rose enthusiasts go to the flower and bird market or nurseries to choose a rose they like, but they may not know how to choose. Let me tell you the specific requirements and selection criteria for choosing roses: first, choose sturdy stems, preferably 2 to 3 branches; second, the leaves should not be wilted and the flowers should be bright in color; third, the petals should be thick and the flower heart should not be exposed; fourth, the outer petals should be curled, fragrant, and free from diseases and pests.
Rose propagation methods: The main method of rose propagation is cutting, typically done in May to June and October to November. Select healthy branches from the current year, cut them into sections 5 to 7 centimeters long, retaining the top 1 to 2 leaves, dip the roots in rooting hormone for 2 minutes, then remove and dry before inserting into moist medium. The medium for cutting can be river sand, vermiculite, or wood shavings, which should be watered through in advance. Spray the cutting medium with water once in the morning every day to keep it moist, and after about 20 to 30 days, the roots will form. When the seedlings grow to 5 to 7 centimeters, they can be transplanted into your preferred pots.
