Wisteria Winter Pruning Time and Method
For most women, the pruning time and method of wisteria in winter and the sharing of the most cold-resistant potted trees are related contents. Let's learn about them together next.
We all know that shrub roses and climbing roses should be pruned strongly in winter, cutting the entire plant to about 25 centimeters, so that they can grow stronger, branch more, and bloom more in the following year. However, many experienced gardeners and experts do not recommend strong pruning for climbing roses. Why is that? If not pruned, how should wisteria be maintained in winter? Today, Mumu will tell you about it.
One: Why Not Strong Prune Climbing Roses
As we all know, climbing roses have large plants, short ones are one or two meters, long ones are five or six meters, and the width is also larger than shrubs and micro roses. The reason why climbing roses have such a large number of flowers is due to their huge plants. If we prune strongly every winter, although the branches that grow out the next year will be thicker, the length of the branches and the size of the plants will not grow too large, and they will be far inferior to the size of the plants that have grown over the years. This will greatly affect the number of flowers in the second year after strong pruning.
Climbing roses need to be planted and supported for a long time, growing out enough length, width, and a large enough plant size to rely on so many branches to bloom a large number of flowers. If pruned like灌木 and micro roses every year, the number of flowers will be the same as theirs.
Two: Actually, This Type of Climbing Rose Also Needs Strong Pruning
However, there are exceptions for climbing roses that need to be pruned strongly in winter, which are seedlings. In the first and second years after planting, it is generally recommended to prune them like灌木 and micro roses.
Because the branches are still relatively weak at this time, whether you are guiding or horizontal pulling, the lateral branches that grow out will also be relatively weak. Therefore, in order to make the seedlings grow fast and stronger, it is recommended to cut the plant to about 25 centimeters in the first and second winters. Although this may affect the number of flowers in the first two years, it will be very beneficial for later growth and branching.
PS: Specific Method
There are actually no overly complicated tricks. In the coldest time of the year, if the temperature is below 10°, cut the entire plant to about 25 centimeters, so that the nutrients will flow back, and the plant will become stronger and older, and the lateral branches that grow out the next year will also be more, and the plant will be stronger. Depending on the actual situation, in the second winter, you can prune strongly again, which will affect the number of flowers in the second year but will quickly make the seedlings stronger and form a flower wall or arch earlier.
Three:剪 Climbing Roses in Winter According to This Method
Adult climbing roses generally do not adopt the method of strong pruning in winter. When it's time to prune strongly during the dormant period, just clean up the dead,rotten, and diseased branches, and then prune some very weak branches.
If there are branches smaller than the size of a chopstick tip on the adult climbing rose plant in winter, they can also be cut off in winter because these branches will only consume the nutrients of the plant and will not bloom.
Wisteria Winter Pruning Time and Method
PS: Mumu's Suggestion
In winter, we should first examine our own climbing roses, cut off some visible diseased leaves and branches, and then look at the whole plant to see if there are any particularly weak branches. Cut them off, and if the disease is severe during the year, remove the leaves as well, and have a clean and hygienic New Year. The plants will bloom honestly in the following year.
Four: Fertilizing Wisteria in Winter
After roses enter the dormant period, they basically do not need to be fertilized or can reduce fertilization. However, for gardeners who have very large plants and roots and like to use organic fertilizers, winter is a great opportunity to apply organic fertilizers.
However, we first need to understand the purpose of using organic fertilizers. At this time, roses have entered the dormant period. Honestly, what's the use of fertilizing? They can't absorb much, and too much absorption without growth can even cause fertilizer damage or waste. The main purpose of applying organic fertilizers at this time is to improve the soil quality. After a year of applying compound fertilizers and other chemical fertilizers, the deposited impurities will adhere to the roots, affecting the soil quality and reducing the organic matter in the soil, which is extremely unfavorable for the subsequent growth of roses. This may also be one of the reasons why roses become less vigorous and grow worse after several years of planting.
Recently, some gardeners asked me about the lifespan of roses, and I started to think deeply about this. Is the decline in vitality of roses after several years of planting due to their lifespan or the environment we provide for them? I think that too much impurity in the soil may lead to the decline in the vitality and the possibility of continued growth of the roots, which may also be a reason for the reduced lifespan of roses.
PS: Mumu's Suggestion
When roses enter winter dormancy or semi-dormancy, especially for ground-planted roses, it is time to start applying some organic fertilizers. At this time, both raw and cooked fertilizers can be used. Cooked fertilizers are those already decomposed chicken manure, sheep manure, etc., available online, while raw fertilizers are things like fish intestines or other animal innards or carcasses that people often mention.
However, I must remind everyone that whether it is raw or cooked fertilizer, do not overdo it. The purpose is only to improve the soil quality. It is indeed true that some people say that after burying fish intestines and other things in winter, the plants bloom well the next year. However, the time that organic fertilizers can provide nutrients is very limited. To have good and abundant blooms, the most direct method is still the daily chemical fertilizers. If organic fertilizers are applied too much, after fermentation, they will be released at once, and too much can even increase the probability of fertilizer damage.
As for the specific usage and dosage, it varies depending on the type of fertilizer and the condition of the plant. Everyone can consult experienced gardeners. I once applied about half a basin of fish intestines to an adult plant of Grandiflora and did not cause any fertilizer damage.
