How should potted roses be fertilized so they grow well?

Roses come in diverse flower colors and beautiful flower shapes. They can be planted as ornamental flowers in courtyards, parks and other places, and can also be grown in pots indoors. So how should potted roses be fertilized, and what else should be noted during care?

How should potted roses be fertilized?

Potted roses do not need much fertilizer; generally, 20-40 granules of compound fertilizer every 1-1.5 months is enough. However, during their vigorous growth period, nutrition must still be ensured: apply more potassium fertilizer before flowering, do not fertilize during flowering, and apply a fruit-setting fertilizer after flowering. Fertilize little and often, and do not apply fertilizer directly at the base of the plant; instead, apply it from the edge of the flower pot.

What else should be noted during the care of potted roses?

1. Watering

Although potted roses do not need to be watered excessively, the plant's water supply must still be ensured during growth and development. Water again once the soil is dry, especially in winter. In winter, the plant's various functions decline, and evaporation also decreases, so watering should be reduced in winter; otherwise, too much water can easily cause waterlogging at the roots and kill the plant.

2. Light

Usually it can be placed on a sunny balcony to get sunlight, and ideally in a humid, high-temperature spot. In winter, placing it in a sunny spot is enough. But in high temperatures and strong sunlight, remember to move it promptly to a shady place to avoid sunburn.

3. Pruning

Potted roses should have crowded branches pruned, or after the plant blooms, aged and withered branches should be pruned; branches and leaves attacked by pests and diseases should also be pruned promptly. In addition, it is best to cut off all branches about 10 cm above the ground so the plant can overwinter smoothly.

4. Pest and disease control

Roses are mainly susceptible to damage from caterpillars and scale insects. Generally, the plant can be placed in a well-ventilated, sunny environment, and excess crowded branches can be cut off, keeping just a few main branches; this can effectively reduce pest damage. When necessary, pesticide can also be sprayed for treatment and prevention. If white spots are found on rose branches, they can be scraped off promptly with bamboo. If the infestation is severe, cut off the entire branch directly and spray pesticide to kill the scale insects.

In addition, when fertilizing potted roses, it is best to do so together with watering; this not only enhances the plant's absorption of fertilizer but also helps avoid fertilizer burn.
