The Latest Rose Growing Methods and Precautions Explained in Detail
The rose, also known as Yueyuehong and Changchun flower, originated in our country and has a cultivation history of more than two thousand years. It was introduced to Europe in the 18th century, where it was repeatedly crossbred with European roses through targeted breeding and artificial selection, resulting in the development of many excellent varieties. So how should roses be grown? Let's take a look together.
1. Pot and Soil Selection
For the flower pot used for cultivation, it is best to choose one with good permeability, with an ordinary clay pot being preferable. New clay pots should be soaked in water before use. In addition, as the plant gradually grows, it should be gradually moved into a larger pot. Roses like fertile soil and are afraid of drought and waterlogging, so a sandy loam soil that is loose in texture, rich in organic matter, well-drained and well-aerated must be chosen. It can be planted within a pH range of 5.6-7.2, but slightly acidic to slightly alkaline soil with a pH of 6.8-7.2 is better. It can also be prepared with garden soil, garbage soil and rice husk ash in a ratio of 5:3:2, plus an appropriate amount of rapeseed cake.
2. Temperature and Light
The most suitable temperature for roses is 18-20 degrees, so in winter attention should be paid to keeping them warm, and in summer attention should be paid to cooling them down. In April-May and September-October, the flowers are larger, have more petals and are more brightly colored. When the temperature rises above 25 degrees, growth will accelerate, but the flowers will not last long. Under high temperatures above 30 degrees and humid climate, not only will the flowers be small, have few petals, be pale in color and faint in fragrance, but various pests and diseases are also very likely to occur, so attention should be paid to temperature regulation. Roses are sun-loving plants and like sufficient sunlight. Daily light exposure must not be less than 5-6 hours, otherwise it will lead to weak branches and leaves, excessive vegetative growth, poor flowering and other conditions. Generally, it is suitable to place them in a place with sufficient light, and at noon in summer they should be properly shaded to protect them from the sun.
3. Fertilizer and Water Management
When watering roses, grasp the principle of “do not water if not dry, and water thoroughly when watering.” Watering should be moderate, neither too dry nor too wet. Generally, in spring water once every two days. As the temperature rises and evaporation increases, the watering frequency should gradually increase. In summer, generally water once in the morning and once in the evening, and also spray water frequently to lower the temperature. For fertilizing, grasp the principle of “apply thin fertilizer frequently,” and avoid applying raw fertilizer or concentrated fertilizer. In winter, applying a small amount of organic fertilizer can enhance cold resistance for overwintering. When buds sprout, a relatively high concentration of decomposed organic fertilizer can be applied. When the flower buds are about to open, apply an additional dilute liquid fertilizer once. After the flowers fade, apply a medium-concentration liquid fertilizer once more to promote abundant flowering in autumn.
4. Precautions
Roses have strong cold resistance and can withstand low temperatures of minus 10 degrees. Generally speaking, in the south there is no need to move them indoors for overwintering. After flowering in October, do not prune, so as not to cause sprouting. Stop applying nitrogen fertilizer and increase the application of phosphorus and potassium fertilizer. This makes the branches strong and enhances cold resistance. At low temperatures, do not let them lose water, to prevent death from dry freezing. Generally, when new shoots grow to 15-20 cm, cut off about 3 cm from the top to promote the sprouting of side buds. When the side branches grow to a certain length, continue pinching them back until the desired branches are achieved.
