The simplest and cheapest way to reproduce rose bushes is through cuttings. This technique is often widely used by amateur gardeners, since it allows obtaining varieties that are difficult to find in the market, and by nurseries to reproduce wild roses, which will be used to graft more delicate varieties.
In this article we talk about planting rose cuttings, their preparation and how to do it with different methods.
Which stems to use to make rose cuttings and when to make them
Cuttings are stems or branches cut directly from the rose bush, which are planted to generate roots and produce new plants. To make cuttings of a rose, any branch that is too old is not useful, the ideal ones are semi-mature branches with a thickness between 6 mm and 10 mm. The ideal size of the branches is between 15 cm and 20 cm in length and that they have some buds.
The two best times to cuttings are spring and fall . If we choose to make the cuttings in spring, it is advisable to choose branches that have been during the previous year that will have a year of life, since they will be more vigorous. If, on the other hand, we make the cuttings in autumn, we will choose branches from that same year and make them look mature.
Advantages of reproducing a rose bush by cuttings
- It is a very inexpensive way to get new roses.
- It is the best way to obtain varieties of roses that are difficult to obtain in other ways.
- The plant generated from a cutting is genetically identical to the original one, that is to say, it is a clone, so by producing them in this way we will be able to know the characteristics that they will have.
Disadvantages of reproducing roses by cuttings
- The rose bushes produced in this way bloom less profusely.
- They have less resistance to drought and excess water.
- They have less resistance to cold.
- Be more vulnerable to fungi.
- Have less half life.
Rose cuttings: how to prepare them
Once you have selected the most suitable branch or stem for your plant, follow these simple steps to prepare rose cuttings :
- Cut the tip of the branch or top in a bevel, an oblique or diagonal cut, just above a bud or shoot.
- Cut the lower part of the branch horizontally.
- Eliminate the leaves, which will prevent perspiration from the branches and so they dry out.
- You will also need to clean the branches, although the technique can be changed here. You can remove a part of the lower bark of the branch, to improve the development of the roots, or you can make a cut on the branch to facilitate its capillarity and thus prevent it from drying out. Another option is not to modify the branch at all.
- But one technique that should always be used is the use of growth hormones, since these increase the chances of success of the cuttings. So, finally, prepare your cuttings, along with the materials to plant them according to the method you choose, among which we will see below, and also the growth hormones.
How to plant rose cuttings: methods and steps
There are several methods to reproduce rose bushes by cuttings . The traditional method is to use a pot with substrate, but there are other alternatives such as growing in hydroponics, using potatoes or using plastic bags. All these methods have in common that the cuttings must have a temperature between 18ºC and 21ºC, not receive direct sunlight and have high humidity.
Rose cuttings on potatoes
This method consists of preparing the cuttings in the usual way, but instead of putting them on stakes on the substrate, they are driven into a potato. Although this system does not mean that we do not have to plant the cuttings in the substrate, it ensures constant humidity in the cutting and that it can take advantage of the nutrients of the potato. As soon as roots grow, it can be transplanted to the substrate or soil.
Rose bush cuttings in hydroponics
In this method, the cuttings or cuttings of the rose bushes are placed in water and, by cutting at the bottom, capillarity is facilitated. In addition, we will need special tubes, and a preparation of peat, vermiculite and perlite, so that they can easily absorb moisture. We must also use rooting hormones and maintain the appropriate conditions, such as maintaining humidity, something that is not difficult with this method.
Rose bush cuttings in substrate
This is the traditional method of multiplying the rose bush by cuttings . It consists of preparing a pot with a substrate rich in peat and placing the cuttings. You can use a specific substrate for cuttings . The correct thing to do is to wet the substrate a little and use rooting agent before placing the cuttings. If it is too hot, you can cover the pot, to avoid excessive perspiration, and water regularly. The cuttings can also be planted directly in the garden, but in a shady place.
Cuttings in substrate and with plastic bags
This is a variant of the traditional method, where instead of using pots, we use plastic bags, so that we create a kind of mini-greenhouse.
Once the cuttings have rooted and have the first leaves, we can transfer them to a larger pot or the garden. This multiplication technique offers good results, since it avoids excessive perspiration.
