Himalayan black Alder (Alnus nitida)bloom during the fall season. The male inflorescences are daisy, reaching a length of about 14 cm, while the female inflorescences are lateral racemic, with a length of about 10 cm.

Single-sex flowers turn into wooden cones, which are ovoid in shape, about 4 cm long.

Himalayan black Alder (Alnus nitida) propagation

Himalayan black Alder (Alnus nitida)are propagated by planting seeds, during the fall season, where the seeds are planted in agricultural beds containing a good agricultural environment, consisting of compost + peat moss + well-washed sand in a ratio of 2: 1: 1 and taken care of. Until the true leaves appear.

After the appearance of the real leaves, the seedlings are spread out in pots or planting bags, until they reach the appropriate length, where they are rotated in pots or larger planting bags until they are planted in the permanent land.

Himalayan black Alder (Alnus nitida) are also propagated by planting crabs that grow under the trees. Trees are also propagated by planting cuttings.

Where the cuttings are cultivated in agricultural boxes that contain an agricultural environment consisting of compost + peat moss + well-washed sand, and when a good root system is formed, the seedlings are separated into pots or planting bags and taken care of until they are planted in sustainable land.

Himalayan black Alder (Alnus nitida) watering

Himalayan black cedar (Alnus nitida) are among the trees that grow well in wet soils. Therefore, attention must be paid to the irrigation process during the seasons of the year, as it is one of the trees that cannot bear thirst.

Attention must also be paid to the process of watering trees on a continuous basis, and that the watering be at very close intervals, especially when planting them in home gardens or public gardens and parks, so that the trees grow well.

Himalayan black cedar (Alnus nitida) propagation

Fertilizing Himalayan black cedar ornamental trees using mineral (chemical) fertilizer neutral NPK 10: 10: 10 of the major fertilizer elements nitrogen – phosphorus – potassium at a rate of 400 g / tree of 3-5 years of age.

Provided that the mineral (chemical) fertilizer is added in two equal batches, the first batch during the month of March, and the second batch during the month of August.

Attention should also be paid to fertilizing trees with well-decomposed organic fertilizer at a rate of 3-5 kg + mono-superphosphate fertilizer / tree of 5-7 years of age during the winter service in December.

Provided that the soil is stirred after adding fertilizers, then the irrigation process takes place without drowning.

bio-environmentally friendly fertilization for ornamental trees Himalayan black cedar (Alnus nitida)

Himalayan black Alder (Alnus nitida) are fertilized using environmentally friendly bio-fertilizers, instead of using mineral (chemical) fertilizers that are harmful to the environment.
Among the most important biofertilizers used to fertilize ornamental trees Himalayan black cedar (Alnus nitida)are the following

biofertilizers:

1- Using the water soaked in compost, known as compost tea.

2- Using active dry beer yeast during the spring season at a rate of 20 gm / tree at all ages.

3- Using bacteria that fix atmospheric nitrogen, such as Azotobacter and Azospirillium.

4- Use Trichoderma fungus, which helps trees absorb rock phosphate in the soil.

5- The use of humic acid, which helps the soil to retain irrigation water instead of losing it through leaching, especially in light and shooting soils.

humic acid helps trees to absorb the microelements present in the soil, such as magnesium, calcium, iron, zinc and manganese, as well as the rest of the microelements in the soil (used according to the recommended rates).

Himalayan black Alder (Alnus nitida) soil

It is very important to plant Himalayan black cedar (Alnus nitida) in light, well-drained, fertile soil, also free of harmful mineral salts, as the trees are very sensitive to salinity, whether the salinity of the irrigation water or the salinity of the soil.

Himalayan black cedar (Alnus nitida) must also be planted in neutral acidic and alkaline soil, where the soil PH should be between approximately 5.5-6.5, in order for the trees to grow well, achieving the purpose of planting them as ornamental trees.

Himalayan black cedar (Alnus nitida) light requirements

Himalayan black Alder (Alnus nitida) must be planted in sunny, well-lit places, so that the trees can grow well.
As the light is important for the process of photosynthesis, in which the plant absorbs the energy it derives from the light reaching the mechanism in the representation of carbon dioxide + water in the building of carbohydrates, from which the rest of the other nutrients necessary for the continuity of plant life, as well as growth and flowering are created well.

Preparing process and sterilization of the hole of soil for planting seedlings of Himalayan black Alder (Alnus nitida)in garden

When planting seedlings of Himalayan black Alder ornamental trees in sustainable land, the following steps should be followed:

1- Determine the place to plant the seedlings, so that they are in sunny places with good lighting and the soil is fertile, light and well drained, as well as free from harmful mineral salts, and the soil is neutral in acidity and alkalinity.

2- The area of the hole is determined, provided that it is 100 cm long and 100 cm wide, then the jar is dug and stirred well, with weeds, impurities, and disturbances removed.

3- After mixing the hole soil well, the following ingredients are added to the joura soil, which are kilts.

* Adding a suitable fungicide to combat soil rot (according to the recommended recommendations) + Adding well-decomposing organic fertilizer at a rate of 1-2 kg + 200 gm of monosuperphosphate fertilizer 15%.

* After adding the previous ingredients, the soil is stirred, in order to mix the previous ingredients well in the soil, and then the process of irrigating Al-Hoora is done without drowning.

4- To sterilize planting hole is covered with a high-density black plastic sheet, provided that the covering process is well completed, then we install the high-density black plastic sheet from all directions, and this is done by placing dry soil on the edges of the sheet with pressure on it to fix it well.

5- After covering the jar well, the covered jar is left for a period of 2-3 months exposed to the sun, until the sterilization process is well completed.

6- After a period of 2-3 months has passed, the high-density black plastic sheet is removed, then the process of flipping the jar is done well.

7- left for 48 hours until it is ventilated alone.

8- The seedlings to be planted are brought, provided that the roots of the seedlings are dipped in the following.

* A suitable fungicide to combat root rot + a root stimulating hormone solution such as indole butyric acid (according to recommended rates).

9- After the seedlings are treated, they are planted in the center of Al-Joura, provided that the place for planting the seedlings is excavated to suit the size and age of the seedlings, and the soil around the seedlings is also gently pressed.

10- After planting the seedlings, the process of irrigating the planted seedlings is done without drowning.

11- The seedlings are monitored after being planted in the permanent land, by conducting the process of irrigation and fertilization regularly, so that the seedlings settle in the soil and give new growths with good characteristics.

Himalayan black elder (Alnus nitida) pruning

It is important to pay attention to the process of pruning and refining Himalayan black Alder trees, where broken, dry and deformed branches are removed, as well as branches affected by fungal diseases and insect pests.

He also likes to remove the tangled branches inside the heart of the trees, in order to allow light to reach the heart of the trees, so that the vital operations of the trees are well done.

Attention should also be paid to spraying trees after pruning and trimming, using a suitable fungicide (according to the recommended recommendations), as well as painting the place of broken and removed branches using a paste of a flower.
