It is important to water, feed and prune the tree in a timely manner. Protection from diseases and pests is also of great importance. To do this, it is worth using fungicides and insecticides.
Description and growth area
Negishi is a white pine that is naturally found in the Kuril Islands and Japan.This tree has a cone-shaped crown and can reach a height of 20 meters. The needles have a dark green color. At the same time, it has a silver tint underneath.
The flowering of the crop begins in May. As a result, cones up to 12 centimeters long are formed on the small-flowered plant. They stay on the tree for up to 7 years, and mature only after 2-3 years. With proper care, a tree can grow for 200 years. At the same time, it is resistant to extreme factors.
Pine can withstand temperatures down to -34 degrees. In addition, it is resistant to air pollution. Today, several types of such pines are known:
- Blue angel - reaches a height of 50 centimeters. The culture is distinguished by a height of up to 50 centimeters and is characterized by a lush blue crown.
- Glauka - trees are medium or small in size. Their distinctive feature is the blue curved needles.
- Negishi is a dwarf shrub that bears fruit abundantly.
- Tempelkhov - within 10 years the tree can increase by 2 meters in height. It is characterized by blue needles with a tint.
There are also single-stem and multi-stem types of crops. Young pine has a relatively smooth bark, but over time it acquires a scaly structure.
Landing rules
Pine Parviflora Negishi is considered not too demanding on the soil. However, before planting, it is recommended to water the soil. This will speed up the adaptation of young plants. Planting can be done from April to September. For this purpose, seedlings aged 3-5 years are most suitable. When choosing plants for planting, you should pay attention to their appearance.Seedlings should have strong branches and dark green needles. At the same time, there should be no areas affected by rot on the roots.
To plant a crop you need to do the following:
- Select and prepare a site. The tree needs a well-lit place that is protected from drafts and strong winds. The depth of the planting hole should be 50-60 centimeters, and the diameter should be 70 centimeters. At the bottom it is worth placing a layer of soil 10-15 centimeters thick. When planting several crops, the interval between plants should be 1-1.5 meters.
- Prepare organic substrate. To do this, you need to combine sand with turf in a 1:2 ratio. When planting a crop in poor soil, a complex fertilizer should be poured into the bottom of the depression. An organic mixture must be placed on top. It should fill the hole 60%.
- Plant a plant. It must be carefully placed in the central part of the recess without damaging the roots. After this, it is necessary to pour in the soil composition and compact it a little. It is important to ensure that the root collar is not covered.
- Water and mulch the tree trunk circle. Immediately after planting, you need to pour 5-6 liters of water under the plant. After which the ground should be mulched. To do this, it is recommended to cover the tree trunk circle with peat or wood chips.
Rules of care
This genus of small-flowered pines is frost-resistant. In addition, Glauka Negishi develops well both in the sun and in the shade. However, plants that live in the garden need to be insulated with protective material, spruce branches or agrofibre, since the shoots can get burned.
Watering
It is necessary to water the Japanese Negishi pine very carefully, since the tree does not tolerate waterlogging. After planting, it is recommended to water the crop with 2-3 liters of water. In dry weather, the amount of moisture is increased by several liters. However, it is important to remember a sense of proportion. This pine is considered drought resistant.
If spring and early summer are dry, you can sprinkle the crown. This procedure is carried out several times a month. It is especially useful for recently planted crops.
Loosening
White Negishi pine requires loosening in the spring. After the soil has completely warmed up, it is recommended to loosen it to a depth of 10 centimeters. This process also needs to be carried out in the summer after rains - several times during the season. This manipulation improves air nutrition of the root system. In autumn, the area around the trunk should be mulched to protect it from frost. It is recommended to do this using bark or wood chips.
Trimming
Negishi pine needs formative and sanitary pruning. In the first case, the plant is given the correct shape. To do this, the buds of the pine tree are pinched. Sanitary manipulation is carried out in the spring - before the buds open.
Top dressing
Mature pine trees almost do not need fertilizing. It is carried out provided that the tree grows for several years. In this case, it is recommended to apply a combined mineral fertilizer.For 1 square meter it is worth using 30-40 grams of the substance. If pine is grown in poor soil, it can be fertilized with organic matter - for example, wood ash. To do this, you need to prepare a solution and pour it under the root.
Preparing for cold weather
With the onset of cold weather, seedlings need to be insulated. Such events protect the culture from the negative effects of cold. In this case, the seedling should be covered with spruce branches. It can only be removed in mid-spring. In the absence of spruce branches, burlap or special covers are used. At the same time, gardeners do not recommend using film. It does not allow air to pass through, so young pines rot.
Application
Negishi is a popular crop that is often used in landscape design. The plant can be used to create compositions with cereals and heather crops. The culture also looks great in rocky flowerbeds. It is not recommended to plant this pine near large trees, as it will get lost against their background.
Experienced designers advise combining Negishi with thujas and acacias. Excellent compositions are also obtained with the participation of barberry or rowan. You should not combine small-flowered pine with birch, bird cherry or lilac.
Pine of the Negishi variety is considered an undemanding crop that perfectly complements any composition on the site. This plant fits perfectly into various ensembles and can be used as a tapeworm. In order for a culture to develop normally, it needs to be properly cared for.
