How to cultivate the "Big Red Hat" rose
This article provides an overview of how to cultivate "Big Red Hat" roses and related topics on rose care and flower cultivation. Let's explore these together.
Roses are known as the "Queen of Flowers," with a natural blooming period from April to September. They have a rich variety of colors and bloom throughout the year, making them very popular. Below are the cultivation methods and precautions for roses, ensuring they get enough sun to grow in abundance. Let's take a look!
Methods for cultivating roses
Light. Roses are tolerant to sunlight and require appropriate shading during the high temperatures of summer. In other seasons, they can be exposed to full sunlight, ensuring at least 5 hours of sunlight exposure per day. However, this also depends on the variety, as some flowers are not tolerant to direct sunlight and require shading to extend their blooming period.
Watering. The principle of watering roses is "do not water when not dry, water thoroughly when dry." When the top 2 cm of soil is completely dry, it indicates a lack of water. It is best to water in the morning; watering at night can leave residual moisture that does not evaporate in time, leading to diseases and pests.
The frequency of watering roses should be adjusted according to the season. In spring and autumn, water every 5 to 7 days. In summer, water twice a day, in the morning and evening. In winter, as roses grow slowly, water every 10 to 15 days.
Fertilizing. In addition to the base fertilizer in the soil, roses also need to be fertilized during growth to supplement nutrients. At the beginning of spring when they start to sprout, use a compound fertilizer with a high nitrogen content. As roses have a long blooming period and high nutrient requirements, usually fertilize with decomposed soybean cake every 10 days before blooming, and also spray a dilute solution of potassium dihydrogen phosphate on the leaves. Stop fertilizing when the flower buds show color.

Soil. The soil should be loose with good internal structure and a pH value between 5.6 and 7.2, which is very beneficial for root growth. A mixture of 2 parts of decomposed leaf soil, 2 parts of perlite, and 1 part of fine sand can be used, with a small amount of base fertilizer added to increase soil fertility.
Temperature. The suitable growth temperature is around 22-25°C. When the temperature exceeds 35°C, methods such as sprinkling water and ventilation can be used to lower the temperature. In winter, the temperature should not be below 5°C to prevent frostbite.
Precautions for rose cultivation
1. Regular pruning of roses is required. When the new shoots grow to 15-20 cm, cut off the top 3 cm. Side branches that have reached a certain length need to continue pinching. After blooming, promptly remove the残花 to promote the growth of new branches.
2. Ensure that the fertilizer is fully absorbed and do not use uncomposted manure, as it can burn the roots and leaves, causing harm to the growth of the roses.
