A Detailed Guide to Rose Planting Methods: Master the Key Cultivation Points in One Article

SummaryPotted planting methods: The suitable growing temperature for roses is around 15-25°C. They like light but should not be exposed to direct strong sunlight. Potting is generally done during the dormant period, and repotting is needed once a year or every other year. In spring, summer and autumn, they should be kept in a ventilated place with plenty of sunlight, watered and fertilized at the right time and in the right amount, and pruned in a timely manner. Open-field planting: Choose a site with relatively high terrain, sufficient sunlight, good ventilation and slightly acidic soil. Pay attention to reasonable close planting and do a good job of fertilizer management.

I. Potted Planting Methods for Roses

1. Light

The rose is a light-loving plant. If there is not enough light, the branches will be relatively slender, but it also should not be exposed to direct strong sunlight, which is not good for flower bud development.

2. Temperature

It takes about 45 days for a rose to go from budding to blooming. The suitable growing temperature is around 15-25°C. At this temperature, the flowers produced are larger and more beautiful. When the temperature rises to 30°C, growth becomes relatively slow, and above 30°C, the flower color fades and the flowers become smaller.

3. Pot soil

For 2-3 year old seedlings, it is best to trim the roots before potting. Properly shortening the old roots helps promote new root growth. When planting, the plant should be upright, the root system must be fully spread out, and the pot soil should not be filled too full.

4. Repotting

Roses are generally potted during the dormant period. Roses grow relatively fast and have a high demand for fertilizer, so repotting is done once a year or every other year. Repotting should also be done during the dormant period. After repotting, water thoroughly twice. Except in winter, they should be kept in the other three seasons in a place with good ventilation, sufficient sunlight and no water accumulation.

5. Pruning

Roses can be pruned appropriately after Qingming. Cut off weak branches, crossing branches, sideways-growing branches and overly dense branches, leaving only robust branches. To prevent nutrient loss, you can select 3-5 buds from the base of the branches you keep and cut off all the branches above them, which is more conducive to the retained branches absorbing enough nutrients and promoting their growth.

(1) Be sure to prune after the buds have sprouted. Pruning too late will affect the first flowering. For even growth, each plant can keep 3-5 main branches, with no more than 7 at most.

(2) Roses also need pruning in the middle stage of growth, mainly to cut off the sprouting branches from the rootstock of grafted seedlings, as well as the residual flowers with leaves and excess flower buds after flowering.

(3) Roses also need one more pruning before winter. The main and secondary branches must be even. Large-flowered varieties can keep 4-6 strong branches, and each branch should keep one strong lateral bud at 30-40cm, with the rest cut off. For trailing and climbing varieties, cultivate the main trunk and simply cut off old branches, weak branches and diseased or pest-infested branches.

6. Watering

Potted roses should be watered thoroughly. Do not water if the soil is not dry. In summer, the temperature is higher and water evaporates faster, so the amount of watering should be appropriately increased. In particular, water thoroughly once in the evening.

7. Fertilizing

Generally, no fertilizing is needed in summer. For robustly growing plants, the method of applying thin fertilizer frequently can be used, about 1-2 times a week. Before 11 a.m., appropriate shading can be provided, and after 4 p.m., let them receive light. Try to avoid direct strong sunlight, which is beneficial for photosynthesis and accumulates nutrients for the next round of flowering.

Roses need to be fertilized after pruning. You can apply 50% human feces and urine mixed with 2% superphosphate. In mid-February, you can apply 3% human feces and urine or 1% urea. Note that when new shoots turn red, fertilizing must not be done, as it will damage the young roots, thereby affecting plant growth or even causing death.

II. Open-Field Planting Methods for Roses

1. The rose root system is relatively well developed, the plant is robust, the growth rate is relatively fast, the flowers are relatively large, and the ornamental value is relatively high. They can be planted reasonably according to the habits of different varieties. When planting roses in the open field, choose a site with relatively high terrain, good ventilation, sufficient sunlight and slightly acidic soil.

2. After choosing the planting site, prepare the land and apply fertilizer. Base fertilizer should mainly be organic fertilizer. Upright varieties can be planted at a row spacing and plant spacing of about 75cm. Vertical-growing varieties can be planted at a plant spacing and row spacing of 40cm. Spreading varieties can be planted at a plant spacing and row spacing of about 100cm. Climbing varieties can be planted at a plant spacing and row spacing of 200cm.
