How to reproduce roses with a high survival rate (three common methods of reproducing roses)

There are four commonly used methods of rose propagation: cuttings, grafting, high pressure and seeds , among which cuttings are the most commonly used.

Rose cutting propagation steps

1. Choose one-year-old healthy and disease-free branches as cuttings.

2. Cut the branches short to a length of about 10-15 cm, retain 2-3 buds on each cutting, and cut a 45-degree slope at the bottom.

3. Soak the cuttings in fungicide for 20 minutes for disinfection.

4. Prepare the cutting medium. The medium must be clean and free of bacteria. Commonly used materials are perlite, vermiculite, peat, and river sand.

5. Insert the cuttings into the substrate at a depth of about half.

6. After cuttings, keep the soil moist. In dry areas, cover with film to keep it moist. It will take about 15-30 days for the cuttings to take root.

Rose grafting method

There are two types of rose grafting: root grafting and stem grafting.

Rose root grafting

Root grafting often uses wild roses as rootstocks and grafting is done by bark grafting. The steps are as follows:

1. Prepare the rose seedlings as rootstocks and cut them directly from the roots.

2. Prepare rose branches as cuttings. There should be a full bud on the cuttings, and a smooth slope should be cut at the bottom of the cuttings.

3. Cut the outer skin of the rose rootstock, insert the cuttings into it, and wrap it tightly with plastic film.

4. After grafting, plant the rose roots in a flowerpot.

Rose stem grafting

Stem grafting is mainly used to make lollipop roses or twig roses. The rootstock is still the rose stem, and the bud grafting method is usually used for grafting. Specific steps:

1. Choose rose stem as the rootstock and make a T-shaped joint on the rootstock.

2. Select a scion and use a knife to cut off a bud of the rose from small to large. The depth should just touch the wood.

3. Pick open the bark of the rootstock, put the scion in it, and then wrap it tightly with plastic film.

4. Use rose stems for cuttings.

High pressure breeding

High-pressure propagation is not commonly used, so I will briefly explain it. The specific method is to choose a rose branch, peel off the outer skin, and then wrap it with soil. After a period of time, it will take root.

The success rate of this method is quite high, but it is more troublesome and not as convenient as cuttings, so it is rarely used now.

Seed propagation

Seed propagation is used by breeding companies when cultivating rose varieties, and the other is to sow rose seedlings for grafting.

Let’s focus on the second use, the sowing of roses.

Rose seeds usually mature after September or October. At this time, you can collect some seeds, dry them, take out the seeds inside and collect them. When the weather gets warmer next year and the temperature reaches 15 degrees, you can sow them. After a year of growth, you can graft roses in autumn.
