When is the best time to propagate rose cuttings (how to propagate potted rose cuttings to achieve a high survival rate)

Which month is best for rose cuttings?

There are generally two ways to propagate roses, one is cuttings and the other is grafting. Cuttings are the fastest way to propagate on a large scale. Many rose nursery bases use cuttings to grow seedlings. So in response to the question, which month is the best for rose cuttings and has the highest survival rate?

Theoretically, rose cuttings can be taken all year round, but it is generally chosen in spring from April to May and autumn from September to October. Because the climate is mild at this time, the survival rate and rooting rate of cuttings are also the highest.

How to take rose cuttings

Roses prefer a warm and sunny environment, and the most suitable temperature is between 18 and 26 degrees Celsius. Therefore, spring and autumn are the most suitable seasons for cuttings.

1. Selection and pruning of cuttings

Try to choose semi-lignified branches after flowering, about the same thickness as chopsticks, because the branches are more active at this time and have more nutrients in themselves.

Cut two buds from the cuttings, about 10 cm in length, and leave two leaves at the top bud. This is to facilitate photosynthesis and help the callus tissue to quickly form roots.

2. Sterilization of branches

Soak the cut cuttings in the prepared sterilization solution in advance. For large-scale propagation in general bases, potassium permanganate can be used to prepare an aqueous solution. Drain and dry the cuttings before cutting.

3. Use and sterilization of cutting medium

The medium for rose cuttings is very important. It must be loose and breathable. You can use a mixture of fine coconut bran and perlite. If conditions permit, you can also add rice husk carbon to help sterilize it. Before cutting, apply a sterilizing liquid to the pot to sterilize the medium to reduce bacterial infection and black stems.

4. Prepare cuttings

Prepare the rooting liquid, dip the bottom of the dried branches in the rooting liquid, and then insert them into the medium of the plug tray. The cutting step is completed, and the next step is the critical maintenance period.

How to care for roses after cuttings

1. After the cuttings are completed, the branches are very fragile. Do not move them back and forth or touch them. This action will affect the formation of rose callus tissue and thus affect rooting.

2. Provide shade

As the temperature rises, the temperature in the greenhouse may rise to above 30℃ at noon. At this time, shade is needed. You can cover the roof with a shade net to lower the temperature in the greenhouse and reduce the occurrence of black poles caused by bacterial infection due to excessive temperature.

3. Curing temperature

Maintain the humidity of the rose cutting environment. An important indicator for the survival of rose cuttings is air humidity. For cuttings in the greenhouse, the leaves can be sprayed with moisturizing spray regularly. For cuttings at home, a plastic bag can be put over a small area to keep it moist. The branches of the pillow rose cuttings will not dehydrate.

4. Transplanting

When more than 20 days or a month have passed since the cutting, we can try to gently lift the branches to see if they have taken root. If the roots are good, we can transplant them into pots.

The above is the experience sharing of rose cuttings. I hope it is useful to you. At the same time, I also hope that you can become a green-fingered person, have a high survival rate of cuttings, and grow roses well.
