Raspberry Bush is usually born in mountain and semi mountain streams, hillside shrubs, forest edges and random stone piles. It grows luxuriantly on barren slopes or under tung tree and Camellia oleifera forests after burning mountains. It likes warm and humid nature and requires good scattered light. Raspberry Bush has no strict requirements for soil and strong adaptability, but it is characterized by fertile soil Slightly acidic soil with strong water and fertility and good drainage to neutral sandy loam, red soil and purple soil.

Raspberry Bush Care in Detail
Raspberry Bush WateringRaspberry Bush needs water during its growth.
It will consume water during the growth period and fruiting period, so it needs to be supplemented. It should be watered regularly during the growth period. We should ensure to meet the growth needs. Raspberry Bush
should not be watered directly to the root. It is best to sprinkle it around and supplement water through soil infiltration. If you just bought or just changed the basin, such raspberry bush
needs to be watered immediately, which can also promote later growth.
Raspberry Bush Soil
Before raspberry Bush is planted, in order to make the soil more fertile, we need to mix some farm manure and the soil on the ground evenly, so that all the sundries and weeds in the soil can be removed. After some deep ploughing procedures, select some low-lying soil, and then dig drainage ditches, In this case, the purpose of digging drainage ditches is to make it more convenient for future management. The plant spacing of raspberry Bush
should be about 1.5m. About 1110 seedlings are needed per mu. Only raspberry Bush needs to be planted in each pit, and it is best to apply some farm fertilizer to cultivate base fertilizer in each pit. The reason for this is not only to prepare the soil, but also to make raspberry Bush more drought and flood resistant in terms of convenient management in the later stage, so as to achieve the effect of increasing production.
Raspberry Bush Light
Raspberry Bush is a light loving tree species, and the light in the early stage plays an important role in yield formation. In the later stage, raspberry Bush has low requirements for light, and likes cool but is afraid of hot. Wild raspberry Bush mostly grows on the edge of forest or ditch slope. Cultivated varieties can grow well only in places with good light. Therefore, when cultivating raspberry bush, we should choose a place with protection and no shade.
Raspberry Bush Temperature
The cold resistance of the cultivated species of raspberry Bush is not as good as that of the wild species. Most raspberry Bush varieties should be buried to prevent cold. However, some raspberry Bush have strong cold resistance. In winter, there is no need to bury soil to prevent cold, and they can overwinter in the open. Raspberry Bush is not resistant to high temperature. They grow poorly in areas with high temperature.
Raspberry Bush Humidity
Raspberry plant has strict requirements on air humidity. The air is dry, the transpiration is easy to burn and wilt in the raspberry plant, and the reproduction of fruit branches is more obvious. The relative air humidity should be about 60% from flowering to fruit expansion; The relative humidity from fruit expansion to harvest should be 70% ~ 80%, so as to avoid burning of raspberry plant.
Raspberry Bush FertilizerRaspberry Bush
should be a large basin with a diameter of 30 cm or more, with enough base fertilizer. There is a plant in each basin, which will be replaced every spring or autumn. In order to ensure yield, raspberry bush with a diameter of 40 - 50 cm planted for more than 3 years should be replaced. The roots of raspberry Bush should be filled with enough base fertilizer, and the rotten soil mixed fertilizer should be the best.
For fertilizer and water management of raspberry bush, base fertilizer should be applied in early autumn. When the root raspberry Bush line begins to reach the growth peak, fertilization can improve soil nutrient status, promote root growth and lay a foundation for high yield in the coming year.
When we apply fertilizer to raspberry bush, we apply fertilizer on the side 40 - 60cm away from the plant, and apply about 0.7kg to each plant cluster. In order to mix the base fertilizer with the soil, we will change the base fertilizer to the other side of the plant next year. Topdressing is divided into two times, mainly based on the needs of raspberry Bush phenology.
The first raspberry Bush fertilizer was mainly nitrogen fertilizer from flowering to young fruit formation, which mainly promoted basal branch growth and fruit expansion. The second topdressing is in the late stage of fruit harvest. The main purpose of this topdressing is to promote the growth and enrichment of basal branches and lay a foundation for high yield in the coming year. On average, we can apply 50 grams of fertilizer to each plant cluster at a time and apply fertilizer on the side 50 cm away from raspberry bushto cover a thin layer of soil.
In areas with drought and lack of rain, it is not suitable for topdressing soil. The fertilizer of raspberry bush can be sprayed on branches or leaves for topdressing outside the root. Water is an important part of the growth of any plant. For raspberry bush, if there is drought in spring bud and flowering and fruiting period, special attention should be paid and watered in time to ensure yield. Raspberry Bush is a shallow rooted plant with a soaking depth of about 40 cm. At the same time, in rainy season and waterlogged depression, pay attention to timely drainage. Frozen water can be irrigated once in cold areas to increase the water storage capacity of the soil in the next spring. In arid areas, raspberry bush can be covered with some organic matter, such as straw, weeds and leaves, which can not only reduce water evaporation, but also increase soil fertility.
Raspberry Bush Pruning
The first raspberry Bush pruning
was planted and pruned in early spring, pruning over dense thin and weak branches and damaged branches. When the new buds grow to 40 - 60 cm in that year, we can choose plants with lower density to promote the germination of new buds and increase the number of new buds. The second raspberry Bush pruning is to prune the basal branches, that is, the new buds in the year. The production practice shows that it is appropriate to cut the base branch in the range of 1.3 - 1.5m. This length not only promoted the growth of fruiting raspberry Bush and increased the yield, but also promoted the complete differentiation of flower buds in the second year. Every year, each plant can retain 6 - 8 vigorous basal branches, and the rest can be cut off. This is a reasonable density of reserved branches. The third raspberry Bush pruning
is after harvest. The mother branches of raspberry Bush should be evenly and sparsely removed.Loganberry

Raspberry Bush Pest & Disease Control
1. Stem rotSymptoms:
This raspberry Bush disease usually occurs in new shoots, mainly endangering the basic branches of raspberry. The pathogen is Minger spore, which is a semi parasitic bacterium. The pathogen of stem rot begins to erode from the sunny side of the new shoot and the place close to the ground, and a gray brown disease spot will appear, and then quickly spread around. With the continuous spread of disease spots, it will lead to the withering of leaves, petioles and other places until the whole plant withers and dies. Usually, the highest incidence rate is in the high temperature and rainy season.Prevention and control measures:
In autumn, we should cut off the diseased branches, then clean the orchard and destroy the diseased branches and some garbage; In the early stage of stem rot, i.e. from May to July, spray 500 times of methyltobuzin or 500 times of thiram; In addition, attention should be paid to the selection of planting varieties. Relatively speaking, black raspberry plant is more disease resistant than red raspberry plant, but it is different in different regions.
2. Root rotSymptoms:
This raspberry Bush disease is an infectious disease caused by poor soil drainage, high groundwater level and many bacteria in the soil. This disease is the main reason for the reduction of raspberry production. The roots of normal raspberries are milky white, while the roots of raspberries with root rot are brick red. The main symptoms were that the new branches were dry and yellow, and the branches died early.Prevention and control measures:
We can choose sandy land with high terrain and smooth drainage for planting, and before planting, we must sterilize and disinfect the soil to prevent the infection of this raspberry Bush disease caused by bacteria in the soil. (Find more healthy fruit
3. Fruit rotSymptoms:
This raspberry Bush disease mostly occurs in the south where there is more rain. In the north, there is less rain and most of it is concentrated in summer, so the incidence probability is lower than that in the south. Fruit rot is a bacterial disease that can grow hyphae in the pulp. Raspberries infected with fruit rot can't be eaten.Control measures:
The control of this raspberry Bush disease requires not only spraying fungicides every day, but also cutting off withered branches as soon as possible to control the excessive growth of annual branches.
4. Leaf spot and stem spotSymptoms:
Leaf spot and stem spot usually form some spots with white heart and brown edge on the branches and leaves of raspberry, which are caused by bacterial invasion. This raspberry Bush disease will affect the normal growth of raspberry and cause the branches of raspberry plant to wither in advance.Prevention and control measures:
We can use 500 times of methyltobuzin solution, 500 times of 40% aluminum ethylphosphate solution and 500 times of Fu Shuangmei solution in spring and autumn; Cut off the bearing branches in time and properly trim the new branches.
5. Short branch necrosis
This raspberry Bush disease
will make the branches appear circular bands, make the branches brittle, and form purple spots with white hearts on the new branches. Short branch necrosis is that the buds on the branches are infected, some brown or purple spots appear, and cause the branches and buds to wither. This raspberry Bush disease will result in no short branches within 45 cm from the ground. Spraying insecticides and keeping the ground clean can prevent and control these two diseases. This raspberry Bush disease is a bacterial disease that can crack branches and rhizomes. This raspberry Bush disease is also very common. For example, healthy raspberries will get sick if they are not trimmed properly. At present, only the whole raspberry bush plant is excavated to effectively prevent the spread of the disease.
Raspberry Bush Propagation
Raspberry Bush Cutting PropagationRaspberry Bush cutting propagation
is generally in autumn. In autumn, the branches with a growth length of 40 cm a year are cut off for storage. In early spring, the branches are taken out, and the one meter wide border is dug. The stored branches are inserted from both ends. The spacing between each raspberry is about 20 cm. The two lines form a border and are arched. The branches are cut off when sprouting buds, In this way, two raspberry plant seedlings can be obtained.
Raspberry Bush Division Propagation
The root system of red raspberry has the characteristics of adventitious buds and is very prone to a large number of root tillers. Therefore, raspberry Bush division propagation is the most common. A large number of root tillers occur around the plant clusters every summer from May to June. In order to cultivate high-quality seedlings, we should timely sparse weak and dense root tillers during the operation of raspberry Bush division propagation
, improve ventilation conditions, keep the plant spacing at 10 ~ 15cm, strengthen the soil and fertilizer management of mother plants, apply quick acting organic fertilizer, combine nitrogen fertilizer, timely irrigate and plough in order to keep the soil moist, loose and nutritious, Promote the vigorous growth of root tillers and seedlings. In production, there are usually two periods to excavate roots and tillers for ramet reproduction. In addition, regardless of summer and autumn festivals, as long as the root tillers have a certain height on rainy days in the growing season, the root tillers can be deeply excavated and planted with the excavation, which can also achieve a high survival rate. However, we should pay attention to the period of digging and planting seedlings should not be too late. We can directly dig out the original younger clumps, cut them into several parts and plant them separately, each with roots and basal branches. Raspberry Bush division distribution can restore the coverage of orchards in a short time, so as to restore the output of the reconstructed orchards as soon as possible.
Raspberry Bush Sowing Propagation
The time of raspberry Bush sowing propagation
is spring and autumn. When selecting seeds, it depends on whether there is a withered site. Selecting good seeds is the prerequisite for the success of raspberry Bush planting. If the seeds are not selected properly, all efforts will be wasted. When sowing raspberry plant seeds, we only need to sprinkle the seeds evenly on the sandy soil, slightly cover the fine soil, and do not cover too much soil. Raspberry Bush seeds cannot be sprinkled too closely, otherwise it will affect the growth of the plant.
Raspberry Bush Benefits
1. Treatment of gynecological diseases
Estrogen in raspberry plant can promote women's growth and development, alleviate women's palace cold and treat infertility. Palace cold, as its name implies, is "uterine cold". The main factor causing palace cold is cold. The main symptoms are increased leucorrhea, backache and backache. Severe palace cold patients will lead to infertility symptoms, so women in menstrual period should pay attention to cold prevention and warmth.
2. Improve vision
Raspberry plant contains a lot of strong antioxidants. Long term consumption can improve vision, especially for teenagers and the elderly. It can improve the symptoms of blurred vision and blurred vision. Friends with visual impairment can buy raspberry in appropriate amount, and the effect is also very good.
Raspberry plant contains rain multivitamin, which has anti-aging effect and can delay human aging. In addition, raspberry plant can also promote skin blood circulation and achieve the effect of beauty. Women who love beauty can take it in an appropriate amount. It not only tastes sweet, but also has a very powerful effect.
4. Cancer prevention and anticancerRaspberry plant
contains anticancer substances. According to professional data, the anticancer substances in raspberry plant fruits have exceeded blueberries. Raspberry has remarkable anticancer effect and is known as "Ruby". We can eat raspberry in an appropriate amount in our daily life. Of course, if we want to achieve good preventive effect, we should also take cancer prevention measures and eat more light food in our daily life.
5. Strengthening brain and intelligence
The antioxidants in raspberry can repair the brain damage caused by free radicals, which is especially suitable for people with excessive brain use. In addition to people who use their brains too much, preschool children can also take it in an appropriate amount. Raspberry can enhance learning, memory and active thinking.
Raspberry Bush Care FAQs
When to pick Harvesting Fresh Raspberries?
Raspberries are planted in two seasons. Harvesting fresh raspberries
are also harvested in two seasons, including summer fruit type and autumn fruit type, i.e. single season raspberries and double season raspberries. Summer fruit raspberries have less fruit in the second year and reach stable yield in the third year. Autumn fruit raspberries can reach stable yield in the second year. Harvesting fresh raspberries takes a short time, Generally, the picking in early June to mid July is basically over, and the fruit picking period is only about one month.
How to Harvest Raspberries?
Raspberry Bush generally grows in a wide area. Sometimes, it will grow well in muddy swamps. There are few people in such areas. Generally speaking, there are more in the jungle. Once it grows, it will be a large area of branches and leaves. If it grows in a place with more people, because it has more thorns and will not produce beautiful flowers, ignorant people will remove them as weeds.
Harvest raspberries is generally the best time around May. During this period, its fruit seeds will not eat more than those in the later stage. Relatively speaking, it has more gravy, smaller seeds and a better sense of direct import. In the later stage, in June, the sun is sufficient. After exposure to the sun, the fruit juice evaporates rapidly, and the mature fruit will dry and shrivel in two or three days, leaving only seeds. In May, we should seize the opportunity to harvest.
When we harvest raspberries, the main difficulty is that there are too many thorns around the branches and leaves. If we are careless, we will be cut and see blood. Therefore, even if the weather is hot, you should wear tight without exposure. At the same time, we should wear deep gloves, preferably rubber, which is close to our hands and does not absorb water. Cotton gloves will absorb water, but you can also wear cotton gloves and put plastic bags on the surface to keep the cotton cloth from contacting the fruit. Otherwise, it is very easy to stain the gloves with juice after breaking the peel, and the cotton thread will absorb part of the juice.
Generally, the mature raspberry Bush is a large clump of branches, and the scope of harvest raspberries is limited. If you manage the time directly, ignoring these branches will lose those unripe fruits growing on the branches, and even break the branches. The branches with fruit are generally more than three years old, and it is not easy to grow again. So try to be careful.Read Next:Best Fruits -19 Fruits That Can Improve Your Health
