When is the best time to prune a rose tree?

The best time to prune roses is in autumn or winter, and pruning the branches is an important step. Aging branches should be removed, and dead branches, diseased branches, weak branches, and unhealthy branches should be removed. For shoots that have previously bloomed more, cut them short in the middle.

There is no requirement for the number of flowers, but the larger ones that need to bloom can be appropriately re-cut, so that the nutrients can be concentrated, and some want to make the number of flowers more, you can leave more buds, try to cut lightly, leaving at least half of the buds, to ensure the number of flowers.

In addition to pruning the branches, it is also necessary to take into account the shoots, choose the buds that grow better next to them, and cut them down about 6-7 mm above, keeping them parallel to the direction of the buds. Be careful to leave the buds that extend outward, as they will affect ventilation when they grow into branches on the inside.

1) Pruning during the growing season. After flowering, prune the residual flowers and thin the diseased branches and delicate branches in time to reduce nutrient consumption and promote the growth of new branches.

2) Dormant pruning. Before germination in early spring, leave 4 5 branches per plant, stub 40 cm to 50 cm from the ground, leave 1 2 side branches on each branch, and leave two bud stubs on each side branch. A rose plant can live for more than 20 years, and the 3-year-old plant blooms at its peak, and begins to decline after 4-5 years, and the yield and quality of the flowers decrease, so it needs to be renewed and rejuvenated.

The method is: for the rose garden that has been planted for 4 to 5 years, the old roots are turned out in winter, the diseased and insect branches and senescent branches are removed, and the overly dense and overly vigorous bushes are divided, or the senescent rose plants are cut off from the ground in autumn and winter, and then the soil between the rose rows is ploughed, and the cake fertilizer is applied and the water is irrigated. In this way, although the next year does not produce many flowers, the next 2 to 3 years will be greatly improved.

Dormant pruning, pre-germination in early spring is best.

Rose pruning is most important after flowering and winter pruning.

During the flowering period of roses, branches with a diameter of more than half a centimeter at the bottom should be pruned, and branches below half a centimeter should be pruned appropriately. After the rose flowering period, it is necessary to cut off the residual flowers, diseased branches and weak branches in time. When pruning, keep a certain distance between the branches.

In its seedling stage, the shoots are pressed down when they grow to more than 20 cm.

During the flowering period of roses, branches with a diameter of more than half a centimeter at the bottom should be pruned, and branches below half a centimeter should be pruned appropriately. When pruning, you can cut off half of the senescent branches of the flower bush, use the remaining branches to produce flowers, and wait until the roses have bloomed to renew the remaining branches.

After the rose flowering period, it is necessary to cut off the residual flowers, diseased branches and weak branches in time to reduce nutrient consumption and promote the growth of new branches. The time is generally carried out after the rose leaves are before germination, leaving 4 to 5 branches per plant, stubbing 40 to 50 cm from the ground, and leaving 1 to 2 side branches per branch.

When pruning roses, the principle is to plant them in a bead-shaped way, with 12 to 20 thick branches per bush and the rest cut off. In the case of off-the-form planting, it is necessary to keep a certain distance between the branches. Cross branches, dense branches, overlapping branches, and slender branches can be cut off, so that nutrients can be concentrated on the flower branches, so that the flower seedlings can grow better.

When the rose is in its seedling stage, when the branch is more than 20 cm, the branch should be pressed down and the branch should not be broken. The newly germinated thick branches are used as cut flower branches, the excessively thin branches are pressed into vegetative branches, and the thin branches on the vegetative branches should continue to be pressed. Stripping should be carried out in the afternoon on a sunny day, and the thin branches within 10 cm of the roots should be removed at the same time.

Rose pruning method:

The pruning period is divided into winter pruning, spring pruning, and post-flowering pruning. Winter and spring pruning, after the roses have fallen their leaves and before budding. It is necessary to make the growing branches properly pruned to ensure the yield of flowers.

Rose branches or lots with poor fertilizer and water conditions, weak growth and many old branches should be appropriately re-pruned to achieve the purpose of concentrated nutrition, promote germination of new branches and restore growth; Pruning after flowering, after the flowers have been harvested. It is mainly used for vigorous growth, dense branches and dense branches are thinned out of honey branches and cross branches, but they should be properly pruned, otherwise it will cause imbalance between underground and aboveground, causing adverse consequences.

Rose pruning technique.

Cultivation of plants.

Newly planted plants, although they still bloom, have slender and short branches, small flowers and few petals, and are not suitable for cut flowers. During this period, in addition to pruning dead branches and diseased branches at any time, buds should also be picked at any time to avoid wasting nutrients on plants. Until the thick branches develop from the base of the plant, after topping to grow into the main branch, and then gradually cut off the slender branches.

Update the trim. Roses belong to shrubs, and the growth potential of the main branches gradually weakens over time after cutting the flowers, so it is necessary to dig out the old main branches at regular intervals and cultivate new main branches at the same time to maintain the growth potential and maintain the plant yield. When pruning, first cut off the old branches that are weak, keep 3 5 of the youngest main branches per plant, and then cut the remaining main branches to 120 cm high. to promote the growth of new main branches at the base of the plant.

Intrapartum regulation. The length of the cut rosette and the number of days from pruning to flowering are closely related to the pruning node. The flowering shoots developed in the axillary buds at the lower node position have a large number of nodes, long branches, and higher grades, but the number of days from pruning to flowering is longer. On the contrary, the higher the pruning node, the fewer flowering nodes and shorter branches developed by axillary buds, but the shorter the number of meshes required to prune to flower.

Roses include cut flowers, edible roses, and industrial roses.

Cut flowers (roses sold in the general market for bottle cuttings, such as: Chinese red, Corolla, Maria and other varieties, flowers are produced all year round in the south): generally pruned after harvest, can be pruned all year round.

Edible roses (roses used to make rose fillings and rose juice, black red flowering period: March to December in the south, Shandong Four Seasons roses, Fenghua roses: flowering period: April to October): After harvesting flowers, prune according to the condition of the plant to achieve the purpose of high yield.

Industrial roses (roses used to extract essential oils and rose hydrosols, such as: Damascus, French thousand leaves and other varieties, flowering period: April to May in the south); Pruning is carried out after harvesting flowers to achieve a good harvest in the coming year.

I don't know if your home is a rose or a moon, at present there are many merchants who sell the moon season as a rose, although it also blooms, and the moon season blooms even better than roses, that is, the fragrance is worse, but the pruning is not the same, the rose pruning time is after flowering, it is best to press it down, but it should be determined according to the buds and the tree potential, the tree is weak and cut from the strong buds to promote the strong branches, and the tree is more vigorous and cut from the weak buds to make the tree balanced, as for the messy branches to be cleaned up after the flower. When the tree is balanced, the flowering will be even. In addition, new roses often emerge from the ground near the old plant, so it is best to cut them off and plant them again in the second year, which is beneficial to both plants.

Pruning Rose pruning can be divided into winter and spring pruning and post-flowering pruning. Winter and spring pruning, after the rose leaves to germination, pruning thinning is the main, each bush selects 15-plus branches to leave stout branches, and the space is large enough to be appropriately short pruning to promote branching, so as to ensure the yield of flowers. For the growth potential, the rose bushes with many old branches should be appropriately re-pruned to achieve the purpose of concentrating nutrition, promoting the germination of new branches and restoring growth.

Pruning after flowering, after the harvest of flowers, is mainly used for vigorous growth, dense branches of dense branches to thin dense branches, cross branches, overlapping branches, but to appropriate light pruning, otherwise it will cause the balance of the ground and underground is out of balance, causing adverse consequences. Pest controlThe main pests and diseases of roses are inducing, black spot, powdery mildew, beetle, longhorn beetle, red spider, etc. Generally, 5 stone sulfur mixture is sprayed before germination to eliminate overwintering pests and diseases; In early April, 0 5 phosphine was sprayed to control beetles and weevils; 5-6 spray 0 5 mites and dicofol to control spider mites; From June to August, spray 2-3 times 0 125 -0 167 antibacterial or 0 5 Bordeaux liquid.

At the same time, in the spring or growth period in time to prune the branches harmed by rust, artificial capture of beetles, weevils, longhorn larvae, etc.

Roses grow vigorously and need to be pruned correctly and at the right time. Rose pruning is usually done in spring and winter, where spring pruners promote the growth of new branches and leaves, and winter pruning ensures that the branches and leaves are sufficiently nutrient.

1. Rose tree pruning time.

Roses are usually pruned in early spring or late winter every year, and early spring pruning can meet the vigorous growth of plants, avoid affecting the overall plant sparse density, and promote the germination and growth of new branches and leaves. Late winter is the dormant period of roses, and pruning can ensure that the nutrients are concentrated for the plants to absorb.

Second, the pruning method.

1.Dormant pruning.

Before the roses go to sleep, remove all the remaining flowers, dead branches and leaves from the plant. Prune the branches and leaves that affect the density in time, and prune the weak branches and leaves, which can promote the healthy growth of the plant and increase its ornamentality.

2.Pruning during the growing season.

Spring is the growth period of roses, prune the branches and leaves that grow too fast in time, and clean up all the long branches and leaves, sick old branches and leaves, and dry branches and leaves. The vigorous branches and leaves are lightly pruned to promote the germination of new branches and leaves. Speed up flowering, increase flowering yield, and improve flowering quality.

3.Prune after flowering.

After the rose blooms, it is necessary to prune the remaining flowers in time to promote later growth and flowering. Pruning the overlapping branches and leaves allows the light to be evenly distributed and avoid disease.

4.Prune after illness.

After roses are infested by pests and diseases, it is necessary to prune the diseased branches and leaves in time and treat them intensively to avoid expanding the infected area.

3. Pruning technology.

Rose pruning needs to be careful to avoid summer, which is hot and dry, which is not conducive to its recovery after pruning. Observe the growth of roses in each period, prune the dead branches and leaves in time, and promote the growth of new branches and leaves.
