How to Grow a Tree Rose? A Detailed Guide to Cultivation Methods

SummaryA tree rose needs to be grown in a flower pot with a relatively large volume, and the bottom must have drainage holes. It is suitable for growing on a balcony or in a courtyard. In spring and autumn, water it once every 7 days; in summer, water it once every 1-3 days; in winter, when the soil is relatively dry, you can water it around noon. Tree roses need more fertilizer than ordinary roses. During the growing period, organic fertilizer can be applied. After sprouting, an appropriate amount of nitrogen fertilizer can be applied weekly together with watering. During the flowering period, an appropriate amount of phosphorus fertilizer, potassium fertilizer, and boron fertilizer can be applied.

I. Choosing a Flower Pot

1. The flower pot chosen should not be too small. Because tree roses are tall in plant form and have well-developed root systems, if the flower pot volume is too small, the roots will be unable to spread normally, thereby affecting the robust growth of the root system.

2. Therefore, it is necessary to choose a flower pot with a relatively large volume for growing it, and the bottom of the flower pot must have drainage holes to prevent water accumulation in the pot. You can choose a flower pot made of hard, relatively thick, durable material that is easy to move.

II. Sufficient Light

1. Tree roses are light-loving plants, so sufficient light must be provided during cultivation, which is beneficial for vigorous plant growth, dark green leaves, abundant flower buds, large flowers, a long flowering period, and bright colors.

2. If the light provided is insufficient, it will lead to dull yellow leaves, sparse and small flower buds, smaller flower shapes, dull flower colors, and premature flower withering. Therefore, tree roses can be grown on a sunny balcony or in a courtyard with sufficient light and good ventilation.

III. Proper Watering

1. In spring and autumn, when the temperature is relatively warm, the evaporation from the soil and leaves of tree roses is not very large, so the water requirement is relatively small. During this period, water once every 7 days. When watering, the soil should be thoroughly moistened, but water accumulation should not occur.

2. In summer, the weather is relatively hot, causing the soil to lose moisture quickly, and leaf water evaporation is also relatively large. During this period, water once every 1-3 days, but each time it must be watered thoroughly, and water accumulation must not occur in the pot.

3. After the surface water in the soil dries, you can loosen the soil appropriately, which is beneficial for maintaining soil permeability. In winter, the temperature is relatively low, and tree roses begin to enter dormancy. At this time, the water requirement is relatively small, so watering may be omitted. If the soil is relatively dry, you can choose to water around noon to preserve soil moisture.

IV. Reasonable Fertilization

1. Because tree roses have a relatively large tree body, their fertilizer requirement is greater than that of ordinary roses. During this period, an appropriate amount of organic fertilizer can be applied. It contains rich humus, has a relatively long fertilizer effect, and is also rich in nutrients. In early spring, when changing the soil, an appropriate amount of organic fertilizer and humus soil can be added, which is beneficial for a long-lasting fertilizer effect.

2. After tree roses sprout, an appropriate amount of nitrogen fertilizer can be applied weekly together with watering to supplement the nutrients needed during the young bud and seedling stage. During the flowering period, an appropriate amount of phosphorus fertilizer, potassium fertilizer, and boron fertilizer can be applied, which is beneficial for promoting more flowering, larger flowers, and bright colors.
