Santa Rosa Plum Care in Detail

Santa Rosa Plum Care & Propagation Guide

Santa Rosa Plum Watering

This shows that the water requirements of Santa Rosa plum are also different at each growth stage. Watering is required at the germination stage and young fruit stage of Santa Rosa plum. And it also needs to be watered and frozen before winter. However, Santa Rosa plum saplings are very afraid of fishing, so when repairing the land, we must improve the drainage system to avoid ponding, so as to improve the yield and quality. However, it should be noted that plum seedlings should not be short of water. If Santa Rosa plum seedlings are short of water, their growth will be affected. If there is serious water shortage for a long time, the seedlings of Santa Rosa plum will dry up and die, so the early care and planting will be in vain. But we can't water too much. We must control the appropriate amount.

Santa Rosa Plum Soil

The adaptability of Santa Rosa plumm to temperature is very strong, and the requirements of Santa Rosa plumm for soil are also very low. As long as the soil layer is deep and there is a certain amount of fertilizer, Santa Rosa plumm can be planted on any kind of soil, but Santa Rosa plumm has higher requirements for air and soil humidity, At the same time, Santa Rosa plum is also very resistant to ponding, so it is required that the orchard has a good drainage effect. If the drainage effect is not very good, it will lead to rotten roots, affect the growth and some diseases. However, when we plant Santa Rosa plum, we'd better choose loose soil, and the soil has good air permeability and good drainage system.
The process of Santa Rosa plum is also very troublesome, so people should pay special attention to it. Sometimes, people also need to have high requirements for soil in the process of planting Santa Rosa plum. If there is no particularly good soil, the yield of Santa Rosa plum will be very low. There have also been cases of small fruit results and poor varieties, and sometimes even worse cases.

Santa Rosa Plum Light

Santa Rosa plum has good ventilation and light transmission, good fruit coloring, high sugar content, thick branches and full flower bud cells_ However, Santa Rosa plum can grow well in places with good water conditions, deep soil layer and less strong light. Where the light is poor on the shady slope and in the tree bore, the fruit ripens late, the quality is poor, the branches are thin and the leaves are thin. Therefore, Santa Rosa plum should be planted in a place with good light and trimmed into a reasonable tree shape, which is very beneficial to the high yield and high quality of plum trees.

Santa Rosa Plum Temperature

Santa Rosa plum is a deciduous tree, and the best sowing time is after falling leaves and before germination. During this period, Santa Rosa plum seedlings were in dormancy and had a high survival rate. We'd better plant Santa Rosa plum in autumn. Autumn is the peak of root growth of Santa Rosa Plum Seedlings, which can grow new roots. The next year, Santa Rosa plum can plant trees directly, and the seedlings will grow more vigorously. In the north, it must be planted after spring. The winter temperature in the north is too low. If plum seedlings are planted in winter, freezing injury may occur, and the survival rate of Santa Rosa plum is low.

Santa Rosa Plum Humidity

It should be noted that during the flowering period of Santa Rosa plum, the environment of "appropriate temperature and low humidity" should be maintained, that is, the temperature is 18 ~ 22 ℃ during the day, 10 ~ 12 ℃ at night, and the air humidity is about 45%. In this period, the occurrence of night freezing injury and excessive temperature difference between day and night (the temperature difference between day and night shall not exceed 15 ℃) shall be prevented. During the fruit swelling and coloring period, the environment of "suitable temperature and humidity" is required, that is, the temperature in white weather is 25 ~ 28 ℃ and at night is 13 ~ 14 ℃; The air humidity should be 60% ~ 70%. During this period, we should prevent high temperature from damaging Santa Rosa plum. The daytime temperature should not exceed 30 ℃, and it is appropriate to increase the temperature difference between day and night to improve fruit quality. Requirements for temperature and humidity in other growth periods: in fruit setting period, the temperature is 22 ~ 24 ℃ during the day, more than 10 ℃ at night, and the air humidity is 50% ~ 60%; During the hard core period, the temperature is 23 ~ 25 ℃ during the day, 10 ~ 13 ℃ at night, and the air humidity is 60% ~ 70%; During the fruit ripening period of Santa Rosa plum, we can maintain the temperature of 26 ~ 30 ℃ during the day, above 14 ℃ at night, and the air humidity of 60% ~ 70%.

Santa Rosa Plum Fertilizer

When repairing the land, we usually eat enough base fertilizer, because this can provide higher nutrients for the seedlings of Santa Rosa Plum. The base fertilizer of Santa Rosa Plum is generally mainly some farm fertilizer, which is generally applied in autumn. This time is the best. Generally, the integral required for each subject is 50 to 100 kg. During the growth of Santa Rosa plum saplings, we need to be fattened in the early flowering stage. Fertilization is generally started ten days before the front teeth of such seedlings, that is, in early April. Then topdressing after flowering. At this time, we can fertilize Santa Rosa plum from the end of May to the middle of June. Fertilization at this time can reduce the occurrence of fruit drop.

Santa Rosa Plum Pruning

When we are in Santa Rosa plum pruning, we should keep the tree shape of this kind of sapling heart-shaped and grow it with great ambition. This shape can provide good light transmission and ventilation, so that some branches and leaves in the branches can have a higher rate of results. Moreover, its service life is also very long, and its later management is very convenient. Generally, this shape needs three organizations. The distance between each layer is about 80 cm, and the second layer needs two. After planting, Santa Rosa plum pruning can be carried out when the saplings are about 40 to 60 cm from the ground.
In summer, Santa Rosa plum pruning is to prune the branches and leaves that grow too long. Generally, Santa Rosa plum pruning is carried out from mid June to early July. When pruning, first of all, the growth points on the branches need to be removed, and each variety and planting method are different, so the removal method is also different. At the same time, it is also necessary to sprain the apex of the newly grown branches and leaves, but they cannot be broken. Be careful not to damage the newly grown branches and buds, because in the later stage, the new branches and buds of Santa Rosa plum are very useful for the results. (Find more healthy fruit here.)
Santa Rosa plum pruning must seize the opportunity to prune during the dormancy period after defoliation, not when there are leaves. This will damage the vitality of plums. Causing a waste of nutrition. Weaken the trees. Santa Rosa plum pruning starts from the time of colonization. Step by step, when pruning, pull first and then cut, so that you can see more clearly which are the back branches, cross overlapping branches and which are too dense. You need to sparse branches to avoid wrong pruning. Santa Rosa plum pruning follows the principle from top to bottom and from inside to outside. The purpose of Santa Rosa plum pruning is to remove excess branches. Let the whole tree ventilated and transparent. Only with good light can flower bud differentiation be carried out well, which is conducive to the result. Moreover, after removing the redundant branches, the burden of the whole tree is reduced, and the fruit making rate and fruit quality can be improved, because with sufficient nutrition, it is easier to produce good fruit.

Santa Rosa Plum Repotting

The flowerpot of Santa Rosa plum repotting shall be made of tile pots, wooden barrels or wooden boxes with good ventilation, water absorption, small holes at the bottom, which are conducive to root growth, high quality and low price, and the shape is mainly circular. Among all kinds of containers, plain fired tile pots are the most suitable for planting fruit trees. The size of the flowerpot can be determined according to needs. Generally, the flowerpot with an inner diameter of 25-45cm and a height of about 20-35cm can be selected for indoor or balcony placement.
The basin soil suitable for the growth of fruit trees is generally neutral and rich in humus sandy loam or sandy soil. Its preparation methods are diverse and local materials can be obtained. Several kinds are introduced: 6 parts of fertile cooked soil, 2 parts of river sand, 1 part of rotten sheep dung, 1 part of rotten leaves and horseshoe fermentation fertilizer, which are mixed evenly and screened according to the proportion. 5 parts of composted soil, 2.5 parts of garden soil and 2.5 parts of sandy soil, and then add 0.5-1kg of 25% nitrogen, phosphorus and potassium compound fertilizer per cubic meter to mix well. 4 parts of garden soil, 3 parts of humus soil, 2 parts of spinning soil and 1 part of plant ash shall be fully mixed and finely screened.
In Santa Rosa plot replanting, we should select seedlings with strong plants, full bud eyes and no diseases and pests, and plant them in pots before budding in spring. Before planting, the roots shall be trimmed, the necrotic roots shall be cut off, and the injured lateral roots shall be trimmed. The long lateral roots shall be cut short to promote the growth of fibrous roots, and the useful fibrous roots shall be kept as far as possible. The long fibrous roots shall be cut for about 20cm, and the roots shall be soaked with 5 degree stone sulfur mixture for disinfection.
In Santa Rosa plot repotting, we should keep the basin soil at a certain humidity and water it in time after it is dry, but it should not be too wet. Water every morning and evening in summer and every other day in autumn. During the dormancy period, watering should be strictly controlled to ensure that the basin soil is not dry. Because the nutrients in the basin soil are washed out in frequent watering, the nutrients in the basin soil have been seriously deficient after 2-3 years. At this time, it is necessary to pour the basin in time. When we carry out Santa Rosa plum repotting, we can first turn the bamboo around the inner wall of the basin, invert the basin and pour it out, then use a sharp knife to cut off the 2-3cm thick old soil and roots around the soil mass, and then put the prepared nutrient soil into a new basin, put the fruit trees with soil in it, add enough nutrient soil, compact and pour enough water.

Santa Rosa Plum Pest & Disease Control

There will be some diseases and insect pests in Santa Rosa plum, so we must prevent this situation in time. When Santa Rosa plum blooms, some chemicals can be sprayed to prevent this. However, when this tree has gum disease, it also needs to be watered more at this time, and the amount of organic fertilizer needs to be increased, so as to improve the resistance of Santa Rosa plum. Be sure to prevent and do not let the seedlings have such diseases. If there are diseases, it will affect the results. Only when Santa Rosa plum grows healthily and healthily can it bear rich fruits and have a better harvest. When planting Plum Seedlings, Santa Rosa plum disease prevention is a particularly important step, and we must be careful.
Santa Rosa plum is one of the tree species prone to root tillering seedlings. Under the action of appropriate soil temperature, good aeration, or too deep cultivation, upper root injury, excessive stimulation during pruning, a large number of root tillers will be produced at the foundation of Santa Rosa plum. Root tiller seedlings can be used to reproduce Plum Seedlings, but excessive quantities will consume the nutrition of the tree, which will affect the growth and fruit of Santa Rosa plum. Therefore, root tiller seedlings that are not used for reproduction should be cut off in time.

Santa Rosa Plum Propagation

Santa Rosa Plum Care & Propagation Guide

Santa Rosa Plum Cutting Propagation

Santa Rosa plum cutting propagation is generally in spring, with cutting survival rate of 90% and transplantation survival rate of more than 86%. The whole process of seedling raising takes only about 40 days, which greatly shortens the seedling raising time.
We set up a plastic shed (bamboo, wood and straw curtain materials) in the shade to clean the site in the shed, and make a cutting bed with fine river sand. With 0.5% potassium permanganate solution or 50% carbendazim or 70% tobuzin or 58% mancozeb 500 times solution, we can strictly sterilize the cutting bed, and the spraying amount is based on wetting the surface of the sand bed. The temperature in the shed shall be kept between 20 ℃ and 28 ℃, and the relative humidity shall not be less than 70%. As it is Santa Rosa plum cutting propagation, we must let the natural scattered light shine in the shed to facilitate the photosynthesis of cuttings. The size of the shed depends on the number of seedlings. Generally, about 250 seedlings can be raised per square meter.
We should collect and cut the young leaves with leaves of the healthy mother tree in full fruit period from the disease-free area (cutting in early spring can collect the non sprouting branches of the previous year, and the thickness should be about 0.7 cm) as cuttings, with a length of 10 cm to 20 cm, and retain 2 to 3 leaves or 3 to 5 half leaves in the upper part. The varieties of cuttings cut shall not be mixed, and labels shall be tied in time. In Santa Rosa plum cutting propagation, we should pay attention to that the ear strips should be semi lignified and free of diseases and pests. Every 50 to 100 cuttings were bundled into a bundle, and the part about 2 cm long at the base was immersed in ABT Rooting Powder No. 1 solution or 0.025% naphthylacetic acid solution with a concentration of 0.005% to 0.01% for half an hour to one hour.
When we are in Santa Rosa plum cutting propagation, we can sharpen the base of cuttings with a knife. Before cutting, use a small stick to punch a hole in the cutting bed, and then insert the cuttings into the hole. The cutting depth is 5 to 8 cm and the plant spacing is 6 to 8 cm. Water immediately after cutting and keep the shed moist in time.
After completing Santa Rosa plum cutting propagation, we should pay attention to the temperature in the shed, bed humidity, ventilation and light transmission. If it is high at noon, we should spray more cold water. Under the condition of ensuring the temperature and humidity required for cutting, the water content of cutting bed should be reduced as far as possible to prevent over wet rotten seedlings. 7 days after transplanting, callus began to produce. After 15 days, cuttings began to root. When the number of roots reached more than 10 and the average length of roots reached more than 5 cm, they could be transplanted.
The principle of "thin fertilizer and frequent application" shall be mastered for young tree fertilization. Nitrogen fertilizer shall be given priority and phosphorus and potassium fertilizer shall be properly mixed. From April to November, 0.05 kg of urea, 0.1 kg of calcium superphosphate and 0.05 kg of potassium dihydrogen phosphate were applied to each plant every month, 8 times a year.
In early spring, sufficient water is the key to ensure the normal growth and yield increase of plum trees. It has a great influence on new bud germination and flower bud differentiation of plum. If drought occurs during germination, we should water in time to end the root dormancy period and improve the soil water content and soil thermal insulation capacity. It can promote root respiration, enhance disease resistance, properly spray rooting agent, promote root growth and improve flowering and fruiting rate.

Santa Rosa Plum Pressing Propagation

Santa Rosa plum can be propagated by layering. We can select the branches of annual plants close to the ground, peel off the middle part of the bark and press it into the soil, control the ambient temperature between 15-20 ° C to ensure that the soil is loose, fertile and acidic. After a period of time, its roots can be cut off and transplanted elsewhere.
Plum trees can be propagated by layering. Santa Rosa plum also has the ability to use part of the vegetative organs of the plant. After a period of human intervention and cultivation, it can be cultured into a complete plant, that is, the ability of asexual reproduction. Such Santa Rosa plum can completely reproduce the properties of the mother plant without change.
Before budding in spring, we can bend the branches of annual plants close to the ground to the ground as much as possible, find the branches closest to the ground, peel off the bark at the near ground end of the middle part, and then bury the peeled part in the soil to expose both ends of the ground, maintain it for a period of time and wait for it to take root.
When we treat Santa Rosa plum pressing propagation, we should prepare loose, fertile and acidic soil as the growth matrix for the part of pressing into the ground, so that the pressing will take root faster, stabilize the surrounding ambient temperature between 15-20 ℃, and water and fertilize appropriately, so that the success probability of pressing will be higher.
Generally speaking, Santa Rosa plum pressing propagation before budding in spring will successfully take root and firm in the late autumn and early winter of that year. At this time, its root system has grown to the extent that it can independently supply nutrition. The connection between it and the mother plant can be cut off, and then it can be excavated together with the root soil for transplanting.

Santa Rosa Plum Benefits

Santa Rosa Plum is a plant with high economic value and outstanding greening effect. Santa Rosa Plum can be used as garden and ornamental.
Santa Rosa plum contains substances such as fruit acid, which can promote the secretion of gastric acid and digestive enzymes, promote gastrointestinal peristalsis, digestion and absorption, and help people with loss of appetite, fullness after meals, constipation and dryness.
Because Santa Rosa plum contains a variety of amygdalin, it can benefit water and reduce blood pressure. At the same time, it is rich in vitamins, which can maintain the throat, dispel phlegm and relieve cough. Teachers, trainers and other people who use their voice excessively can use it.
Santa Rosa plum contains a variety of amino acids, such as glycine, glutamine, etc. it is suitable for people with sallow comPlumion and emaciation. It has a certain therapeutic effect on freckles and black spots. Long term consumption can see the effect, and the skin can be moist and full.

Santa Rosa Plum Tree Care Tips

About why Santa Rosa plum tree is full of flowers but few fruits.
Because Santa Rosa plum tree itself is a tree species that is easy to flower. Although it is full of flowers every year, it has heavy flower and fruit drop and low fruit setting rate. There are many reasons.
One is the degeneration of flower organs in Santa Rosa plum tree. For example, incomplete flowers are often produced due to malnutrition, freezing of flowering period and genetic factors, which are mainly manifested in thin, short, deformed or degraded flowers.
Second, some Santa Rosa plum tree varieties have low self flowering and fruiting rate or can not self flowering and fruiting, so a certain number of pollinating trees need to be configured.
Third, Santa Rosa plum tree blooms early, and its flowering period is easy to be affected by disastrous weather such as cold wave, low temperature, frost and strong wind, resulting in freezing or poor pollination of flowers and young fruits, resulting in heavy flower and fruit drop.
In short, although Santa Rosa plum tree is easy to plant, you should understand its growth and Fruiting Habits, know the other, and then make reasonable pruning, scientific fertilization and watering and other management measures according to its own characteristics, so as to obtain high-yield, high-quality and stable plum fruit.
