Osaka pine is also known as gold leaf five-needle pine, one of the cultivated varieties of Japanese five-needle pine, is a more valuable kind of five-needle pine, generally used as bonsai material selection, planting is relatively rare. How much is a Japanese Osaka pine? How to maintain it? How to make and trim bonsai? What if the leaves turn yellow? It is learned from Jiujiang seedling base that Osaka pine is widely used for grafting and propagation, and the price ranges from more than ten yuan to hundreds of yuan.

How to maintain Osaka Matsu in Japan?

1. Lighting requirements

The five-needle pine likes the sun, bears the cold, fears the inflammation and heat, and avoids shade. In hot summer, high temperature is disadvantageous to its growth. It is appropriate to give shade and cool down to facilitate growth. Osaka pine is less sun-resistant than ordinary five-needle pine, and more attention should be paid to proper shading in summer.

2. Control watering

The five-needle pine is resistant to drought and avoid water dampness. proper buckling of water can shorten the needles, especially in the period before and after budding to release the needle. If you water too much, the needles will become longer, and the stagnant water will easily cause rotten roots to die. The basin soil should be slightly dry. Of course, watering should be different in different seasons and different periods.

3. Controlled fertilization

Five-needle pine is resistant to barren and should not be fertilized more. More fertilization or concentrated fertilizer is easy to damage the root system, high temperature season is not suitable for fertilization, serious cases can cause the death of trees. The needles can be shortened by controlled fertilization, and the needles will be longer, usually in spring, once or twice each. Fertilization was even less in the year when it was planted in pots.

4. the basin is too small and shallow.

The five-needle loose selection basin should be slightly small and shallow, and avoid being too big and too deep. Small pots are good for short leaves, while too large and deep pots are easy to rot. The cliff type can use a deep basin, and the bottom of the basin needs more broken tiles for drainage and ventilation.

5. New plant planting

To buy Osaka pine without pots, we must pay attention to the selection of soil balls to keep the purchase intact, only in this way can we ensure survival after planting. Acid sandy soil with good permeability should be selected when planting. After being watered once after planting, it is maintained in an environment without direct sunlight and ventilation. Must wait until the soil is fully dry before the second watering, usually use spray pot to spray water to the leaf surface and around moisturizing. Normal maintenance can be restored after half a month.

How to make and trim the Osaka pine bonsai in Japan?

Production:

1. Bundle branch

The trunk and main branches of Osaka pine are wound tightly with skinned aluminum wire (with skin to protect branches). The winding direction is 45 °with the cross section of the trunk, and the suitable thickness of aluminum wire can be selected according to the thickness of the branch. the thickness of aluminum wire is suitable for bending branches and fixed shape, too thick and easy to hurt bark, too thin, weak force is easy to rebound, can not meet the modeling requirements. Bend the main branch according to the modeling design scheme to make it roughly in line with the modeling orientation, waiting for the final meticulous adjustment.

2. Coil bundle branch

After the Osaka pine branch winding is completed, the winding tube is wound into a winding with thin wire in the same way. we must choose an aluminum wire coil of corresponding thickness and tie it to each branch of the tree. Only one can be carefully adjusted and have fun.

3. Change the basin

Osaka pine is taken out of the original basin, and the root of the original root is removed to stretch freely. The old territory is waiting for the basin to be changed. Choose purple sand basin, use plastic mesh cushion at the bottom to prevent basin soil erosion, fill a small amount of new nutrient soil in the basin, in order to change the basin. Will cut off the root length, retain as many capillaries as possible, and then put into the pot on the left side of the Osaka pine on the 1go 3 position (because of its overall growth trend to the right, so the correct position leaves a large space in the basin to meet other requirements, fill in) in the compacted perennial nutrient soil. In the basin tile moss at the same time, pour water in the semi-shade, which is half of the daily maintenance and management.

Trim:

Osaka pine pruning can be carried out during the dormant period from late November to late February of the following year. As the five-needle pine only sprouts terminal buds, not adventitious buds, so it should not be forced to repair. If the pruning is too heavy, pine resin is easy to flow out of the wound, and the flow of resin will affect the growth and development of Pinus elliottii. The pruning period should be from early winter to early spring before the sap begins to flow. The cut after pruning had better be sealed with wax, sticky wood, adhesive tape and so on, so as to avoid the outflow of pine resin.

What about the yellowing of pine leaves in Osaka, Japan?

The reasons and treatments for the yellow leaves of Pinus elliottii are as follows:

1. Too much watering, or too much Rain Water, makes the soil too wet for a long time, causing lack of oxygen in the soil, causing rotten roots and yellowing needles. The suitable soil moisture should be between 15% and 30%, less than 10%, poor plant growth, easy to wither; more than 35%, rotting roots and death.

2. In the hot summer, the hot sun is exposed to the sun, the strong light is direct, and the water evaporates quickly, causing the leaf tip to burn and turn yellow, especially after the rainstorm, the sky turns sunny and suffers direct sunlight, water supply and demand is out of balance, physiological drought occurs, resulting in wilting.

3. Violation of life habits. Put the five-needle pine indoors for a long time, lack of light, lack of ventilation, against the habit of growing outdoors, or suddenly moved to the outside to be exposed, the needles will be withered and yellow. In order to avoid the withering and yellowing of five-needle pine needles, corresponding prevention and rescue measures should be taken in view of the above reasons.
