1. Cutting time

Rose cuttings are generally carried out in spring and autumn. If you use bud cuttings, April-May or September-October is appropriate. If you use branch cuttings, it is better in early spring and late autumn.

2. Cutting method

1. Select branches: Good branches are the first step to successful cutting. Generally, lignified hard branches are used, with a length between 10-15 cm and at least 3-4 buds. Remove the leaves at the base of the hard branches and cut the lower part into an inclined plane to increase the contact area with the soil and help rooting.

2. Pot soil preparation: Rose is not suitable for growing in an alkaline environment, so acidic soil containing humus should be used. River sand can be added appropriately to increase its drainage. The soil used for cuttings generally does not add base fertilizer, which is not good for plant rooting.

3. Make cuttings: Use chopsticks to poke a 5 cm deep hole in the pot soil and insert the branch into the hole. After compacting the soil, water it thoroughly. If the temperature is very low, you can use wooden strips to build a small shelf, wrap it with plastic film, and place it in a sunny place.

4. Follow-up maintenance: Whether the branches can survive mainly depends on three factors: ventilation, temperature and moisture. Open the film regularly every day to ventilate the branches to ensure air circulation. The temperature should be controlled at around 23-27℃, which is suitable for branches to take root. Watering should not be too much, just a moderate spray of water.

3. Pruning time

1. Pruning of the bottom branches and leaves

The branches and leaves at the bottom of the rose will no longer bloom. If you continue to keep them, In addition to consuming nutrients in vain, it will also affect the ventilation and light transmission of the plants, and even cause water accumulation to induce diseases and insect pests. Therefore, do not hesitate to cut off all the branches and leaves at the bottom of the rose.

2. Pruning of withered flowers

If the remaining flowers are not cleaned up in time after the rose flowers bloom, it will not only waste unnecessary nutrients and affect the growth of the next flower buds, but also And it is easy to rot and induce fungi, so the remaining flowers after blooming must be cleaned up in time.

3. Pruning the branches after they grow into shrubs

When the roses have grown into small shrubs, they also need to be pruned regularly and appropriately. Generally, pruning is done every spring, when the frost period is almost over and the rose season is about to enter the growth period. The extent of pruning is to cut off 1cm above the branches.

4. Pruning of rose flowers in the seedling stage

When roses are still seedlings, they often produce flower buds. Seedlings need to consume a lot of nutrients to produce flower buds, which affects their growth. It's extremely detrimental, so don't be reluctant and be sure to cut it off ruthlessly.

Notes on rose flowers:

1. Antifreeze. Rose flowers are very cold-tolerant and can withstand low temperatures of -10°C. Generally speaking, potted roses in the south can be placed directly under the south-facing eaves for the winter. Potted roses in the north should be moved indoors to a ventilated place before the temperature drops to 10°C. It should be noted that after the flowers wither in October, do not prune and apply decomposed phosphate fertilizer once to promote strong and substantial branches and enhance cold resistance.

2. Pruning. When the new rose branches grow to 15 to 20 cm, you need to cut off about 3 cm from the top to promote the formation of branches. When the side branches grow to a certain extent, you can also top them off. Repeat this time until the rose plant shape is plump and the flowers bloom more. many.

3. Upper basin. Potted roses at home involve the issue of repotting and repotting. Repotting is usually carried out in early spring before germination. Replace with part of the new soil, water it thoroughly, place it in a cool place, and move it to a sunny place for maintenance after a week.

4. Prevention and control of pests and diseases. When the environment is poorly ventilated and the light is insufficient, rose flowers are easily disturbed by pests and diseases, such as aphids, powdery mildew, black spot, etc. When pests and diseases occur, spray pesticides in time to avoid affecting flowering.
