This article introduces the related information about choosing the right fertilizer for winter fertilization of Chinese roses. Please refer to the detailed introduction below.
The temperature has dropped significantly these days, so please remember to add more clothes to keep warm and take care of yourself in order to better care for your beloved flowers. After this round of cooling, we are one step closer to the severe winter, and it's almost time to prune and repot the Chinese roses and apply winter fertilizer. Are you ready to get to work?
So here's the question: What type of fertilizer should be used for winter fertilization of Chinese roses? How to choose between fermented organic fertilizer and slow-release fertilizer? Is bone meal useful? Today, let's answer these questions for you.
1. Difference between fermented organic fertilizer and slow-release fertilizer
Many flower enthusiasts are confused about the difference between fermented organic fertilizer and slow-release fertilizer. Which one is better? Both types of fertilizers are thoroughly described in the book "How to Grow Chinese Roses from Scratch." There's no standard answer to which one is better, as each has its own advantages. Let's first look at the characteristics of fermented organic fertilizer.
Organic fertilizers come from animal excrement or the remains of animals and plants, which, after fermentation, become fermented organic fertilizers. Fermented organic fertilizers contain very complex nutrients, including not only major elements like nitrogen, phosphorus, and potassium but also a large amount of organic matter, as well as many trace elements.
Adequate organic matter is a necessary condition for the survival and reproduction of microorganisms, and microorganisms are important indicators of soil fertility and health. The number of bacteria in the soil is vast; they can decompose various substances in the soil, even the residue of chemical fertilizers and pesticides. Actinomycetes can also convert organic matter into antibiotics, which inhibit other harmful bacteria.
The fermented organic fertilizer contains a lot of organic matter, which, when applied to the soil, can promote the growth and reproduction of a large number of beneficial bacteria, maintain soil fertility, and keep the soil structure good, which is the real significance of using fermented organic fertilizer.
The characteristic of slow-release fertilizer is that it is highly concentrated, requires a small amount to use, but relatively has a single nutrient. Most slow-release fertilizers only contain the three major nutrients: nitrogen, phosphorus, and potassium. Even if trace elements are added, they are minimal. The nutrients in slow-release fertilizers rely entirely on artificial addition, so in terms of overall nutrition, they are certainly not as good as organic fertilizers.
The advantage of slow-release fertilizers over fermented organic fertilizers lies in their high concentration, less usage, and cleanliness. Although current fermented organic fertilizers like sheep manure and chicken manure are odorless, many indoor flower growers are still worried about odors, making slow-release fertilizers the preferred choice.
The suggestion is to use fermented organic fertilizers for potting and soil mixing, while slow-release fertilizers can be used for topdressing during the growing period, simply sprinkled around the pot, which is more convenient.
2. Is bone meal really useful?
Bone meal is a natural phosphorus and potassium fertilizer with long-lasting effects. It is a good organic phosphorus and potassium fertilizer that can be used for flowering plants and fruit trees, with good effects on promoting flowering and preserving fruits.
But some people find that bone meal doesn't work for promoting flowering, which might be because they didn't use it at the right time. Bone meal is a long-acting phosphorus and potassium fertilizer and is not fermented, so it should be used in advance, not just when flowering.
Generally, it should be used 15-30 days before the plant begins to form flower buds. In this way, the bone meal will slowly ferment and be absorbed by the plant, achieving better results.
3. What type of fertilizer should be used for winter fertilization of Chinese roses?
After all this discussion, do you have an answer to what type of fertilizer should be used for winter fertilization of Chinese roses?
If the Chinese roses are planted in the ground, a large amount of raw fertilizer can be buried in the winter. Fish intestines are recommended because, after fermentation, they contain a lot of phosphorus and potassium fertilizers, which are great for flowering Chinese roses. (When burying raw fertilizers, pesticides such as phoxim or earthworm丹 should be used simultaneously)
If fish intestines can be buried for ground Chinese roses, what about potted ones? For potted Chinese roses, don't think about burying fish intestines, as there may be many unexpected situations. It is recommended to use fermented organic fertilizers, such as sheep manure or chicken manure, combined with bone meal. Mix sheep manure and bone meal in a 5:1 ratio, then it can be mixed with soil or placed at the bottom of the pot mixed with a small amount of soil as a base fertilizer, which works just as well as burying fish intestines.
The detailed introduction to the question of what type of fertilizer should be chosen for winter fertilization of Chinese roses, as described above, do you understand now?
