English Walnut Care in Detail
English Walnut Watering
English walnut watering must be carried out. After propagation, root fixing water needs to be poured once. After each fertilization and topdressing, water should also be added to promote the absorption of fertilizer nutrition by tree roots. English walnut is a water loving crop. To ensure the water required for walnut growth, we should replenish water to English walnut in time in case of continuous dry weather, so as to prevent water shortage of walnut and adverse impact on growth and development.
English Walnut Soil
For English walnut soil, we can choose sandy loam or calcareous soil with pH of 6.5-7.5. It can be propagated in places with deep, loose and fertile soil and good drainage.
The soil is too sticky and wet, and the soil with poor drainage is not suitable for propagation. Walnut is a light loving fruit tree, which requires sufficient light. When building a garden in mountainous areas, we should choose the south slope as the best.English walnut
soil finishing is an important link to improve the survival rate and growth and development of walnut cultivation. Land preparation is generally carried out half a year before afforestation. We can choose suitable soil according to the site conditions of walnut garden.
English Walnut Light
English walnut is a light loving tree species. We should pay attention to propagate density and proper shaping and pruning to solve the problem of light in English walnut propagation.
English Walnut Temperature
English walnut is wet and waterlogging resistant, but not cold resistant. It is also necessary to keep warm in winter after harvest to prevent freezing damage. We can paint the lower part of the tree white and dry it before English walnut enters winter to play a role in heat preservation. In case of heavy snow, remove the snow around the tree in time. We can also cover plastic film to increase the ground temperature and prevent English walnut from freezing damage.
English Walnut Humidity
English walnut likes dry air, so we should note that the humidity of English walnut should not be too high. English walnut has large water demand and strong drought resistance during the growth period, but it is sensitive to the requirements of soil water status. Excessive drought or humidity of soil is not conducive to growth and fruit. When propagation in mountainous areas, we should do a good job in water replenishment and water conservation of English walnut in winter and spring and dry seasons. When propagation on flat land and in rainy seasons, we should solve the problem of drainage.
English Walnut Fertilizer
If we want English walnut to grow well, suitable soil is essential. The fertility of soil will directly affect the growth rate and fruit rate of English walnut. By properly cultivating the soil, we can also increase the water content in the soil, enhance the permeability of the soil, improve the fertility of the soil, promote the growth of English walnut, and improve the yield and quality.
The growth of English walnut requires a lot of nutrition. We can apply base fertilizer during soil cultivation, fully mix and stir the base fertilizer with the soil, and enhance the fertility of the soil. In the later stage of English walnut fertilizer, we can make appropriate topdressing according to the tree growth, weather changes and the degree of nutrition in the soil. Fertilizer cannot be directly poured into the pit. We should pay attention to mixing evenly with the soil, which may burn the roots.
English Walnut Pruning
English walnut pruning is crucial. When we propagate English walnut,
we'd better choose two to four-year-old walnut varieties. The survival rate of English walnut is higher. Before propagation, we'd better properly trim English walnut. We trim some diseased branches and dead branches, and keep some healthy branches. If the walnut tree has flower buds at this time, We'd better remove part of the male flower buds and keep more female flower buds.
In addition, we'd better trim the roots properly, and cut off some useless old roots and diseased roots. The length of the rhizome should be determined according to the size of the crown. Generally, the larger the crown, the longer the rhizome should be retained. After English walnut pruning, we'd better apply appropriate disinfectants and live preservatives on the wound at the root.
Reasonable English walnut pruning is the key factor to make walnut trees high yield. If pruned after falling leaves or in the germination period, it is not conducive to wound healing, resulting in tree diseases and insect pests. We should try to put English walnut pruning after harvest. Pruning the tree at this time can effectively adjust the structure of the tree. Although it will have a certain impact on the accumulation of nutrients, it is not a big problem.
English Walnut Repotting
First, we need to open a small hole in English walnut and soak it in water. Remember to change the water once a day, but the water doesn't need too much. We just need to keep the bottom of English walnut wet. A few days later, put English walnut in a sealed plastic bag. Soon, white and tender roots will grow, and tender buds will appear in about seven days.
English walnut can be propagated in the flower pot after germination. We don't have to pay much attention to the pot soil. We just need to dig some soil on the roadside and put it in the flower pot. We don't need to bury the base fertilizer. We can bury the walnuts directly. Once English walnut begins to grow, a large walnut tree will grow, so we need English walnut repotting at this time. Moreover, the soil of English walnut repotting should also be replaced with fertile and deep nutrient soil. Although the tree shape of potted walnut trees is much smaller than that of ground grown walnut trees, they are larger than ordinary potted trees. Generally, they can grow as big as fortune trees. In English walnut repotting, we just need to bury the root system deeper. Don't forget to water it often, so that it can grow normally.English walnut
has strong adaptability and low requirements for soil, so it can survive in low-altitude plains or high mountains, high temperature of 40 degrees Celsius or low temperature of minus 30 degrees Celsius.
English walnut needs constant pruning in the growth process, especially the potted walnut tree, which needs pruning modeling to maintain the perfect propagation shape. However, do not trim it during its dormancy period, otherwise it may cause bleeding, so it is best to do it in autumn in order to heal the incision as soon as possible. When pruning, avoid the period of results, otherwise it may affect the quality of results. Small walnut seedlings cannot bear fruit, so they can be pruned in advance in summer; English walnut can bear fruit when it is grown, so it can only be pruned after fruit picking and before the leaves turn yellow.
English Walnut Pest & Disease Control
English walnut has strong disease resistance and does not have as many diseases and pests as other crops, but English walnut sometimes causes diseases and pests due to improper management. Failing to deal with diseases and pests in time, resulting in growth and development obstruction or death. We should regularly spray chemicals on English walnut for prevention, patrol the orchard, determine the disease according to the incidence, then treat the symptoms, and do a good job in orchard disinfection and cleaning after harvest.
English Walnut Propagation
English Walnut Grafting Propagation
English walnut grading promotion is conducted from late March to early April. First, we need to collect English walnut scions. In mid March, when the buds are about to sprout, we will collect 1-year-old branches with strong growth and no diseases and pests as scions. After harvest, we will store them in wet sand by varieties. In early April, we will start grafting when the buds of walnut rootstocks sprout. The rootstock shall be about 1.5cm thick and grafted 10cm away from the ground.
There is bleeding during English Walnut Grafting Propagation, which is not easy to survive. Within 12 hours before grafting, the rhizosphere must be engraved until the xylem is "drained", and then split or skin grafting shall be carried out. After that, the wound shall be tied with plastic strip, and the upper end of the scion shall be coated with paint to prevent moisture evaporation. After survival, the sprouting should be removed and untied in time. The unting time should be when the new growth is more than 20cm. When English walnut
grafted seedlings grow to about 40cm, we fix them with small bamboo poles or wooden sticks to prevent wind folding.
English Walnut Sowing Propagation
English walnut seeds can be kept or purchased. If you keep your own seeds, pick the walnuts in time when they are mature every autumn, then remove the green skin of walnuts, dry them after cleaning, and store them in a ventilated and dry storage environment. If we are buying seeds, we must pay attention to selecting relatively new seeds with better quality. Generally, it is best to have about 20 to 30 seeds per kilogram. English walnut seeds will increase the propagation cost.
English walnut sowing propagation is generally carried out from March to April every spring. Seeds need to be germinated before sowing. Because the seed skin of walnut is very thick, the germination time of English walnut sowing propagation is relatively longer, but germination can save the time of seedling raising. English walnut can use sand to promote germination or water directly. First, let's learn about the germination method of sandy soil. First, soak walnut seeds in water for about three days. At this time, English walnut seeds have fully absorbed water. Then we can stack English walnut seeds mixed with wet sand, and the stacking height is about 35cm. Generally, the walnut seeds in the sand begin to show their white heads in about ten days. At this time, English walnut can be propagated.
The method of soaking in clean water to promote germination is relatively simple. We can directly put English walnut seeds in clean water. In order to avoid poor water absorption effect of walnuts floating up, we can press them in water with a wooden board. Walnuts will sprout after soaking for about ten days. The soaking process needs to pay attention to changing the water every day to avoid deterioration of walnuts.
Before English walnut sleeping propagation, we need to prepare the land. Generally, the row spacing of the field is about 60 cm and the depth of the ditch is about 15 cm. When propagation, the plant spacing of walnut is kept at about 20 cm. After sowing, cover about 6 cm of soil and water it. Generally, walnut seeds will emerge one after another in about 25 days.
