What Fertilizer is Good for Rose Top Dressing
Rose Top Dressing Time
The best time to fertilize roses is from April to June in spring, when the branches and buds start to sprout. It's advisable to apply some diluted organic fertilizer or cake fertilizer monthly to provide ample nutrients.
What Fertilizer to Use for Rose Top Dressing
Firstly, fertilize during the roses' vigorous growth period, and then during the bud differentiation and bud formation stage. It can also be applied when changing soil. During the growth period, use cake fertilizer water, and during the flowering period, use potassium dihydrogen phosphate solution. For base fertilizer, using wood ash or bone meal is acceptable.
Note that cake fertilizer water needs to be diluted with water before application, and potassium dihydrogen phosphate should also be diluted, with a concentration of 0.2%. Base fertilizer should be mixed directly into the substrate, and top dressing during the growth period is generally once a week.
Should You Use Urea or Compound Fertilizer for Rose Top Dressing
Roses can be fertilized with chemical fertilizers, which include nitrogen, phosphorus, potassium, and compound fertilizers. Inorganic fertilizers have a high content of effective ingredients, dissolve easily in water, and are easily absorbed by plant roots, also known as fast-acting fertilizers.
Rose Top Dressing Method
After the roses bloom, top dressing is needed to promote the next flowering. In autumn, apply more phosphorus and potassium fertilizers and less nitrogen fertilizer. Also, fertilize after each pruning. When applying foliar top dressing, the spray should be even and thorough. Do not spray on rainy or cloudy days. It's better to fertilize a few days after watering, spreading the fertilizer evenly around the plant, 20-25 centimeters away from the stem.
Principles of Rose Top Dressing
If the nutrient supply is insufficient at the beginning of spring, the growth of the bud points will be poor, such as blind buds and blind branches, which will affect the later flower yield of the roses. Since most of us grow potted roses, the nutrients in the potting soil are limited, so fertilizing is an important step in the early spring care of roses.
Amount of Rose Top Dressing
Apply solid fertilizer before the roses bloom, such as Meleke bar-shaped slow-release fertilizer, which is convenient. At other times, except for the winter dormancy period, spray liquid fertilizer once every two months. Fertilization should focus on applying thin fertilizers frequently. Chemical fertilizers should be applied according to the dosage instructions on the packaging, and an appropriate amount of organic base fertilizer should be added to the potting soil.
Precautions for Rose Top Dressing
1. When fertilizing roses, avoid using high-concentration fertilizers, and do not apply excessive amounts of fertilizer to prevent fertilizer damage.
2. Do not over-fertilize when the plant's growth is poor. In summer when temperatures are high and in winter when temperatures are low, the plant will enter dormancy. During this time, fertilizing should be avoided to let the plant rest properly. If the fertilizer concentration is not properly controlled, it may burn the plant.
