This article introduces you to the experience of flower planting in the ultra-practical annual rose maintenance guide. The specific contents are as follows: Ultra-practical annual rose maintenance guide This article summarizes the purchase, cultivation, daily maintenance, precautions, pruning, etc. of rose maintenance. Introduce the experience of rose cultivation in several aspects, and welcome leave a message to supplement the shortcomings!
1. Purchase of rose
Rose selection can select varieties and quantities according to your own time, space and preferences. You can purchase a small amount of strong adult plants for the first time, which has low risks and quick results. At the same time, flower friends first buy a strong adult tree and plant it, cultivate it well, explore it clearly, and then collect branches for cuttage.
2. Rose cultivation and transplantation
1. Special attention should be paid to transplanting roses-minimizing root damage.
2. The best time to transplant roses is just before they sprout in early spring or after the leaves fall dormant in late autumn. Choose cool and humid weather in spring and autumn. If you have to transplant in summer, choose morning and evening or cloudy days.
3. Pour thoroughly water on the rose before transplanting to protect the roots to facilitate excavation and soil conservation. Excavated roots should be avoided exposed to the air as much as possible, and bare-rooted seedlings should be strictly moisturized to avoid air drying. In fact, only dormant plants can be so exposed during colder seasons and cloudy days, and roots should be soaked with water as soon as possible.
4. Each plant retains no more than four strong branches, and the rest are cut off from the base. The remaining branches also need to be cut to about 20 centimeters. Large plants or very strong branches should not exceed 30 centimeters. 1/2 of the leaves on the branches should also be thinned out. Pay attention to smooth cutting and ensure that plants transplanted in summer must not retain flower buds. Because the rose is in a slow-growing state at this time, flowering will consume a lot of nutrients, which is not conducive to plant growth. Transplanted in autumn can retain one branch and one bud, provided that the plant is very strong. If transplanted in spring, the roses should be pruned in early winter in advance, mainly removing weak branches, pest and insect branches, and shortening the long branches and main branches to focus on shaping. For transplants in autumn, they can be pruned a few days before transplantation or moved with the cutting.
5. Pay attention to straighten the plants after entering the pit or basin, and press it slightly when filling about half of the soil. The original soil mass must be lower than the ground or the edge of the basin. Fill up the soil and step on it firmly or compactly.
6. Pour through water after filling, and pour through water again in the evening of the next day. On the fifth day, water was poured. If there is rain during this period, reduce watering appropriately. If transplanting in summer, the plants should also be sprayed and moisturized in the morning and evening. Also pay attention to proper shade and do not expose it to the sun. 7--10 After the seedlings are successfully slowed down in about a day, the sunshine will be gradually increased.
7. After planting, you can also spray 50% carbendazim wettable powder with 800 times solution to the plants to control powdery mildew and black spot.
8. The roots of newly transplanted roses need to be restored. Do not apply any fertilizer at this time. Only after the new branches and leaves grow can you add fertilizer little by little, and pay attention to "applying fertilizer thinly and frequently."
3. Daily maintenance of rose
This part coordinates Beijing, and all parts of the country should be analyzed based on their own geographical location.
Supplement base fertilizer in January and February every year and dig pits near the roots. If conditions permit, it is best to dig circular grooves. Add organic fertilizer/hemp residue/cake fertilizer and the like, and pig, cow, horse and sheep dung is better. At the same time, mix some sulfur powder and lime, mix them into liquid and spray them on the roots of the plants to prevent insects.
After it completely warms up in early April, nitrogen fertilizer is applied and watered thoroughly to make it grow vigorously and encourage buds. The most powerful nitrogen fertilizer is urea fertilizer. Give it once in spring. If you give it too much, it will cause it to grow wildly and not bloom.
Aphids are most likely to appear on buds in mid-April. Observe carefully. If there are few aphids, they will be pinched to death, and if there are many, they will have to be sprayed. I used "chrysanthemum killing" and the effect was very good. Be careful to eliminate the aphids when the first buds appear from mid-April to early May. It will be difficult to apply medicine once the flowers bloom. After spraying it once and then spraying it every three days, you can basically eliminate it completely. However, the concentration must be strictly followed in accordance with the instructions. It can only be less but not more. If the concentration is high, the buds will be burned.
When the first batch of flowers bloom in mid-May, phosphorus and potassium fertilizers will be replenished every half month. It can be irrigated with roots or sprayed leaves. Properly controlling the amount of water during the flowering period can prolong the flowering period. When the water is too big, the flowers will wither quickly.
From May to June, you can enjoy the fruits of your labor and take photos or something.
Starting from the end of June, plants in completely unsheltered areas can be appropriately shaded.
July enters the rainy season, and it doesn't matter if it comes once in a while. Long-term rainy weather will cause various mycosis early. In July, it is necessary to regularly spray preventive molds such as carbendazim/chlorothalonil. In addition, drugs to prevent and control various small meat insects must be sprayed.
In August and September, the new non-flowering side branches and some wild branches that affect the plant type should be cut off. First, it is to save nutrients, and secondly, the branches and leaves are too dense and unventilated to cause pests and diseases. At the same time, a slow-release fertilizer should be added to prepare for a full bloom in autumn.
Transplanting or changing pots can be carried out from late October to November. If you have been planted for more than two years or if you have been planted in pots that are too large, you can remove 5 to 8 centimeters of topsoil and replace it with new mixed nutrient soil.
The whole plant can be pruned from December to February, and the suitable branches cut can be cut for cuttage.
4. Matters needing attention
1. Daily watering should be dry and wet. I like roses very much, but my roots are afraid of waterlogging. Don't soak them all the time. Pour more on hot days and less on cold days. Never water under the scorching sun. Pour them in the morning and evening in hot weather. When watering, try to root irrigation, otherwise if there are bacteria on the upper leaves, they will follow the water flow to the lower leaves, and the whole plant will become infected.
2. Rose likes large fertilizer, but you must apply it thinly and frequently------
3. Rose likes the sun but is afraid of being exposed to the sun. More than half of the varieties will be scorched and curled in the scorching sun. Use the thinnest sunscreen to properly cover the shade. Potted plants can be moved to the shade of the tree to avoid the heat when the sun is strongest.
Generally, daily pruning of roses is to remove the residual flowers after flowering, and the position is one or two leaves under the flower. The main reason is to see the thickness of the branches. One leaf for the thick branches can be used, and two leaves for the thin ones can be used. The incision should be tilted to prevent water storage and illness.
Observe more often and clean up the infected branches when they appear. One type of insect branches is a small hole with a diameter of 1 to 2 mm in the cross section of the wooden stem. There must be insects inside. Cut it off little by little until the insects are found. The other is that a small black hole as large as half a millimeter appears on the flower bud and flows out of black juice. Such buds need to be cut off directly, and there are small meat worms inside.
7-9 Clean up small side branches that do not bloom in time in the month, generally no longer than one long, and there are no flower buds on the top. The branches themselves are dark green and look very old, and the attached branches are completely cut off. Another method is to always clean off the flower buds after blooming in late spring and early summer, so that in early autumn, there will be the same batch of blooming flowers as in spring. The advantage of this method is that it saves nutrition and will not let the plant It is very tired and is conducive to the growth of the plant.
The autumn pruning should be later and wait until the rose leaves are completely dormant. If the pruning is early and new buds grow, it will be frozen when the temperature is low, which will affect the growth of the following year. I plan to cut it before spring. In my personal summary, there are the following points to pay attention to: 1. Don't cut locally grown roses, especially those with relatively close plant spacing, otherwise the branches will be short and strong, which is not conducive to ventilation. Of course, this must also be consistent with personal preference----Cut less if you like tall tree-like plants, and cut more if you like short and flaky plants.
2. Cut more of the plants with slender branches to promote the plants to be strong, and cut less of the thick ones to pull them up and support the scene.
3. For the overall plant type, you must be willing to use scissors. The overgrown branches occupy an area and affect the overall appearance. It is best to cut them off.
4. Old branches will reduce the number of flowering with age, so they can be cut off and replaced year by year, rather than remove them all at once.
