What is the best time to fertilize roses
Rose is a very common flower species. As a potted plant, it has a very high ornamental value. The delicate petals are very beautiful against the backdrop of green leaves. Next, we will discuss how to fertilize roses to make them grow better.
When to fertilize
First, let’s talk about the light requirements of roses. When we plant roses indoors, we should avoid placing them in a living room without light for a long time. We should often place roses in a well-lit place for appropriate light exposure. This will enable them to transform nutrients normally and produce the nutrients they need for their own growth. If there is no light, the leaves of roses will turn yellow and the roots will rot. At this time, some fertilizers need to be added to supplement the nutrients needed by the plants.
The four best stages for fertilization: 1. When changing pots, 2. Rose flowering period. 3. After the flowering period. 4. Winter dormancy period.
How to fertilize
When fertilizing roses, a small amount of fertilizer is needed. Using too much fertilizer will cause root rot and it is easy to burn the roses. We can add a small amount every month according to a certain ratio based on the growth of the flowerpot and the rose. If the roses grow well, you can use the water for washing rice to irrigate them. No other fertilizers are needed.
Precautions
1. Pay attention to the impact of diseases and insects on roses. Roses are usually harmed by aphids. We can spray some insecticides to prevent the intrusion of diseases and insects.
2. When choosing soil, ensure the moisture and air permeability of the soil. Choose garden soil containing humus, which can make the roses grow stronger. Every spring, change the soil for roses and always maintain a good growth environment. In the rainy season, roses will cause white mold due to the high humidity in the air. At this time, they need to be treated with drugs as soon as possible.
Red roses are particularly good and are a symbol of love. To be honest, roses are not suitable for potted plants. If your friends live in the courtyard, they are very suitable for planting in the courtyard. Because roses have a well-developed root system, lush branches and leaves, and consume more nutrients during the flowering period, potted plants are not recommended. If you like potted plants, I will talk about my own suggestions below. I hope it will be helpful to you. Please forgive me for any shortcomings.
Time and frequency of rose repotting
Rose has a well-developed root system, so I basically repot it once a year. Since roses are deciduous shrubs, the best time is after the leaves fall in late autumn or before the roses sprout in early spring.
Requirements for roses in pots
In the actual potting process, potted roses often grow poorly, with yellow leaves, fallen leaves, smaller flowers, lighter colors, and loss of flavor. Why? It is because the potting soil is easy to compact and lacks nutrition. In fact, it is the result of too little potting soil and insufficient nutrition. Therefore, it is recommended to use large and deep pots for rose potting to grow small flowers.
Requirements for soil
Rose does not have strict requirements on the pH of the soil, and can grow normally in slightly acidic soil to slightly alkaline soil. Therefore, in the process of repotting and changing soil, adhere to a principle of choosing: loose, breathable, permeable, fertile, sandy soil is appropriate. This way, there are more options to choose from. Suggestions:
Ordinary soil
4 parts of garden soil or soil under trees + 2 parts of leaf humus or peat soil or pond mud + 2 parts of river sand or coal slag + 2 parts of decomposed pine needles or sawdust or leaves + a little bone meal or superphosphate. These soils can be changed according to local conditions. It is cheap and simple. Growing flowers is a “fun” word. I always think that it is not good to waste too much money.
More luxurious soil
For the sake of ordinary people, I have been dealing with organisms for many years, so it is not recommended to use these expensive things. In fact, there is not much difference. Suggestion: Use 5 parts of red jade soil + 2 parts of leaf humus + 2 parts of dry sheep dung balls or cow dung soil + 1 part of plant ash or bone meal.
The simplest and most feasible method
Is To go to a flower shop or market to buy special soil for growing roses. However, if you do this, hehe, does it mean that you have lost the fun of growing flowers?
Fourth, special reminders
Root pruning for repotting
Be careful when removing the pot. Cut off the old roots and diseased roots after the roots are exposed, and cut less fibrous roots, otherwise there will be slow seedlings and slow growth in the future. If you prune too much, you must pay attention to disinfection and sterilization, such as applying wood ash or soaking the roots with 50% carbendazim.
During the potting process, pay attention to drainage.
For example, it is okay to put a layer of broken rubble, coarse sand or ceramsite at the bottom of the pot. A layer of humus at the bottom of the pot, it is recommended to use a well-rotted sheep dung ball. Also, during the planting process, you must pay attention to the soil half pot soil to lift the roots, so that the soil and the rose roots are in close contact to prevent hollowing, and then add soil. It is best to water the roots in time after planting, so that the roots are in close contact with the soil, and take advantage of the rose’s slow seedlings and later growth.
Fertilization reminder
Rose is a plant that likes fertilizer very much. Generally, during the planting and growing period, it is usually applied with decomposed cake fertilizer water once every 2 weeks. At the same time, phosphorus fertilizer and potassium fertilizer can be added once every 2 weeks in spring, which is conducive to flower bud differentiation and bud growth. It is recommended to use 0.2% potassium dihydrogen phosphate directly.
Loosen the soil in time
During the fertilization process, some friends like to use compound fertilizer or nitrogen fertilizer, which is easy to cause soil compaction. Pay attention to loosening the soil every time you fertilize or loosen the soil in time after watering.
