How to cultivate spring roses to make them bloom vigorously
Let me tell you about how to cultivate spring roses to make them bloom vigorously and some related introductions about green plants and flower care techniques during the spring season. If there are any mistakes, please feel free to correct them!
It's now March, and the weather is getting warmer day by day. The branches of the roses in the garden are sprouting red buds, and after a few spring rains, sturdy suckers will grow from the bottom. As long as we take good care of the flowers, these new buds will grow into flowering branches and bloom beautiful flowers in the spring. Spring roses are most likely to "starve," and if we do four things right to supplement their nutrients, they will have lush foliage and continuous blooming!
1. Re-potting potted roses in time
Roses can be divided into two types based on the planting method: potted and in-ground. In-ground roses are planted in the soil, and we just need to make the soil fertile enough through fertilization; potted roses are planted in flowerpots, and the space available for soil in the pots is limited. After more than a year, due to reasons like root congestion and the absorption of fertilizers, the soil in the pots will gradually become hard, compacted, insufficient in fertility, and alkalized, severely hindering the growth and blooming of the plants. To meet the growth needs of potted roses, it is usually necessary to repot and change the soil once a year.
2. Adding base fertilizer to roses
Roses prefer well-drained, breathable, and fertile soil. If the soil is hard, heavy, or lacks fertility, it will lead to weak growth and reduced flowers in the later stage. When repotting roses in spring, we should use loose and fertile soil. Beginner gardeners can directly purchase bagged nutrient-rich soil, while experienced gardeners may consider mixing their own soil.
There are many methods to mix soil for roses, and here is a relatively simple recipe: 7 parts coconut coir, 2 parts coarse coconut chunks, 1 part perlite, mix all materials evenly and use them for planting. When mixing soil, remember to add some fertilizer as a base fertilizer. Base fertilizer is the foundation of the entire soil nutrition, which is very important. For potted roses, it is recommended to use milder organic fertilizers as a base fertilizer, such as well-rotted cow dung, sheep dung, worm castings, and sesame cake fertilizers. A small amount mixed into the soil is sufficient, as excess can cause fertilizer damage.

Applying base fertilizer to in-ground roses is much simpler. The base fertilizer for in-ground roses can be the solid organic fertilizers recommended above or chemical fertilizers like compound fertilizers or slow-release fertilizers. If using solid organic fertilizers, you need to dig some small holes near the rose roots (not too close to the roots), and then bury a little fertilizer in the holes. The fertilizer will gradually seep into the soil to provide nutrients. If using chemical fertilizers, usually, they do not need to be buried in the soil. Just sprinkle a little fertilizer evenly on the soil surface around the roses.
3. Supplementing liquid fertilizer
As long as the weather is warm enough in spring, the new suckers of roses will quickly grow into branches and bloom wave after wave of flowers. We need to regularly add liquid fertilizer to supplement nutrients for the flower buds. In spring, fertilizing roses is mainly divided into two stages: the growth stage and the flower bud formation stage, and the fertilizing methods for these two stages are also different.
Growth stage
The young shoots of roses will not form flower buds at first; they need to grow into branches, and only after the branches reach a certain length will they start to form flower buds. The process of young shoots growing into branches is the growth stage. During this stage, roses mainly grow leaves and branches, and we mainly use liquid fertilizers high in nitrogen, such as Huaduo 1, Huaduo 10, and foliage plant nutrient solutions. According to the instructions, mix the fertilizer into clear water to make a fertilizer solution. Pour the fertilizer solution at the base of the rose plants, using it once every 7-10 days.
