Roses need sunlight, preferably direct sunlight. The best time is 6-8 hours, some types need less sunlight, around 3-5 hours. If there is not enough sunlight, roses will grow slowly, have many diseases, have small flowers, and fewer flowers.
Roses like well-ventilated places, the plants should be placed far apart so that the wind can blow through each plant, limiting diseases and making it easier for plants to absorb nutrients, and medicines to work faster.
The general principle when mixing soil is: loose, airy, and nutrient-rich.
Some ingredients that help the soil to be airy and light: coconut coir, perlite, pumice stone, etc.
Some ingredients that supplement and retain nutrients: clean soil, peat moss, various organic fertilizers, etc. The mixing ratio depends on the planting conditions: for example, if you plant in a small, poorly ventilated balcony with limited sunlight, you need to add more ingredients to make the soil more airy and light, such as coconut coir, perlite, pumice stone, peat moss, etc. If you plant in a place with heavy rain, you should limit the use of coconut coir because it absorbs water and retains it for a long time. If you plant on a terrace, you should limit the use of clean soil to make it easier to move. When planting in a general environment, the soil mixture usually consists of coconut coir, coconut fiber, perlite, pumice stone, peat moss, etc.
- Roses like moisture but cannot tolerate waterlogging, so the plant pot must have many holes to ensure drainage for the plant.
- Plastic pot. In addition to being lightweight and sturdy, plastic pots can also meet the requirements of ventilation for rose roots and are suitable for the development of rose seedlings. Although the sun will increase the temperature of the plant pot, affecting the roots of the plant to some extent, plastic pots are still the best choice for planting on balconies and terraces.
- Ceramic/pottery pot. This is the best type of pot for planting roses because it has the function of absorbing water and retaining moisture, keeping the roots of the plant protected and cool (even when the outside temperature is high). The disadvantage is that it is heavy, has limited designs, and is quite expensive.
- Porcelain/enamel pot, Cement pot. Although they look beautiful, they have poor ventilation and are easy to break, so they are not recommended for use.
- Watering principle Water when the surface of the soil is dry. Water gently until water drains out of the bottom of the pot, then stop.
- Timing Water in the morning and early evening, and water the leaves to wash them clean, avoid diseases, and help the leaves of the plant photosynthesize better. Do not water the plant at night because the plant is prone to fungal diseases at this time.
- Note Each stage of development and each type of rose will have different water needs. You need to monitor to provide the most appropriate amount of water for the plant.
1. Where do rose plants get their food from?
- Through the roots: Thanks to the tiny hair on the root, from a single root, the root system branches out into many levels, so the total area of nutrient uptake from the soil is very large. The roots absorb water in the soil and some elements dissolved in the soil solution such as nitrogen, phosphorus, potassium, sulfur, magnesium, calcium, and other trace elements. The root system is the main organ that takes food for the plant.
- Through the leaves: Leaves and other parts on the ground, including the bark, can directly absorb nutrients. There are many small holes (stomata) on the leaves. Stomata are the place where nutrients are absorbed through the pathway of spraying through the leaves.
2. What nutrients do rose plants need?
- Macro-nutrients: Nitrogen, phosphorus (P), potassium (K)
- Secondary nutrients: Calcium (Ca), sulfur (S), magnesium (Mg)…
- Trace elements: Iron (Fe), zinc (Zn), manganese (Mn), boron, copper (Cu), molybdenum (Mo), chlorine (Cl)…
- All of the above elements are essential for the plant, a good fertilizer regime must be complete and balance all the factors above.
3. Fertilizing according to stages
- Before pruning dead flowers (about 3-4 days). At this stage, the development of the root system is important, so we need to supplement the plant with fertilizers containing Phosphorus. Phosphate fertilizers contain a lot of phosphorus, which is found in many types of fertilizers: cow, buffalo, goat…
- After pruning dead flowers. Leaves are very important in the development of the plant. The stage after pruning dead flowers is the time when the plant is weakest due to the removal of branches taking away the nutrients that the plant stores in the branches. Along with fertilizing to develop the root system, we also need to protect the leaves. After pruning dead flowers, spray leaf nutrients for the plant, the type of Mầm garden is often used as seaweed leaf fertilizer.
- When the plant has young shoots and buds. At this time, the leaves are responsible for photosynthesis and supplementing nutrients for the plant. At this stage, the plant needs more nitrogen than other types of nutrients. Therefore, fertilize with nitrogen-rich types such as chicken manure, earthworm castings, soybeans, eggs,… In addition, still fertilize with phosphate-containing fertilizers such as stage 1 to stabilize the root system.
- When the plant has buds. At this stage, it is necessary to supplement the plant with potassium, which is abundant in bananas… If the plant is healthy and full of nutrients, the flowers will be healthy, while the color and form depend on many climatic factors.
- Throughout the fertilization process, it is necessary to monitor the changes of the plant to adjust accordingly.
- Fertilize with the right amount and regularly instead of fertilizing a lot but occasionally. Thank you for following and supporting Pemdas Garden. We wish you a healthy and beautiful rose garden! Opening hours: every day of the week (including holidays).
