Rose cultivation, nutritional balance is key.
For netizens to detail the introduction of roses, rose cultivation, nutritional balance is key, next, the editor will answer in detail for you.
Many balcony roses are cultivated with soil-free media such as peat, perlite, and vermiculite. Using slow-release fertilizer as the base fertilizer and water-soluble fertilizer for topdressing is very clean; however, it disrupts the plant's balanced need for nutrients, often causing plants to lack trace elements, and the lack of trace elements can also lead to excessive absorption of macroelements, resulting in nitrogen, phosphorus, and potassium poisoning.
In fact, the simplest explanation is, can people live on trace elements alone? If the elements needed by people can be maintained by direct intake through medication, why does humanity still need to eat even with today's advancements in technology? The reason is simple, food is not only for people to absorb enough elements but also to keep various systems functioning normally, so that people can be healthy. The same is true for plants; chemical fertilizers can also provide various nutrients needed by plants, but chemical fertilizers are like medication, and plants cannot be healthy with just enough nutrients; they also need to keep their various systems functioning normally.
Plants' absorption of organic fertilizers and soil nutrients is equivalent to the operation of the human digestive system. If you want plants to be healthy, not only should the absorption system function but also the digestive system. Many friends are worried about the strong smell of organic fertilizers and are reluctant to use them because they might burn the seedlings. However, well-fermented organic fertilizers basically have no smell, slightly resembling the scent of a forest after rain, and they will not burn the seedlings. The application method is also simple, just mix it directly with the medium or sprinkle it on the soil surface.
As for pests and diseases, the process of fermenting sheep manure will produce high temperatures of 60-70 degrees, killing pests and diseases long ago. However, it must be completely fermented because unf fermented manure can indeed breed pests like small black flies, which can be very troublesome, and the fermentation process can produce harmful gases.
Roses are flowers of the north, and because they need to be cold-resistant, they inherently require a large amount of fertilizer to resist severe cold.
The above is the introduction to the method of rose cultivation nutritional balance as a reference suggestion for everyone.
