Cinnamon is a plant variety that brings high value to farmers. However, to get high-quality cinnamon, you need to pay attention to techniques for growing and harvesting cinnamon in Vietnam.
How to grow cinnamon
You can choose one of the methods of sowing seeds or cuttings. However, many reports show that growing cinnamon by cuttings often gives a very high yield of cinnamon.
The best seeds are from perennial plants that are 10-15 years old. Those seeds can grow very well. Besides, they are less susceptible to pests and diseases, and give high annual yields. The seeds of these seedlings have high germination capacity, bringing many advantages from genetic characteristics from the mother plant.
In addition, you can choose to go to reputable seedling stores and distributors to find good seeds.
Note: Do not choose flat seeds, scratched seeds, too dry seeds with low germination rate, or moldy seeds when planting. They will be very weak, slow-growing for poor cinnamon bark yield.
Making seed nursery
After choosing a good seed, you need to take advantage of the preparation of the soil. Choose light, sandy soils for growing cinnamon.
Note: To avoid planting cinnamon on alluvial soil, arid soil lacking vitality or near polluted areas.
The area where cinnamon is grown should not be released from livestock or pets. It is necessary to avoid them biting and contaminating the soil. Planting on a large area needs to be plowed and harrowed carefully, in beds 10m long, 1m wide, 20cm height
Dig planting holes about 60x60x60 cm and lined with powdered lime and farmyard manure 3-4kg/m2 and spread evenly on the beds. Let dry for about one month before planting.
Seed treatment
While waiting for lime and manure to clean the soil, you proceed with the steps of germinating seeds in trays and pots.
- Soak the seeds in clean water for about 3-5 hours. Then putting the soil in the hole in the nursery tray.
- In each hole in or nursery, you put 1-2 seeds in, cover with kitchen ash or coir on the surface.
- Watering with mist once a day in the early morning. Then placing the planting tray in a location with gentle sunlight.
After about one month, the plant has developed about 5-7 true leaves. After that, you move the tree to the planting ground to take care of and fertilize.
You dig a hole in the lined, then move the young cinnamon tree into the hole and fill the root. Design more stakes around to make the tree more stable, to avoid falling during storms. When the tree is about 20-30cm tall, you can remove the supporting stakes.
Combine tilling for weeding, to limit insect bites and weeds that encroach on the growth space of plants.
After 2 months from the start of the planting, the first phase of fertilization is carried out: each tree fertilizes about 0.5kg of NPK fertilizer mixed with water and fertilizes about 20cm from the root.
Phase 2 fertilizes phase 1 after two months, apply 1 kg of NPK fertilizer mixed with water and water 20cm from the root.
Phase 3 fertilizes phase 2 after two months, apply 1 kg of NPK fertilizer mixed with water and water 20cm from the root.If the tree is stunted, it is necessary to apply more nitrogen fertilizer with a concentration of about 0.3% of the dose of 1 liter/m2.
Pruning dry branches
Although all branches and leaves of the cinnamon tree are useful, you should remove dead branches and leaves that are infected with pests to avoid spreading to the whole plant. For the tree to focus on developing the canopy, the level 1 branches (the main pillar branches of the tree) will produce a higher yield and quality cinnamon bark harvest.
Pruning is done on warm sunny days. After pruning, people need to treat the cut with lime or other solutions. This helps keep ants and insects away from new cuts.
Pest control for cinnamon trees
Root rot disease: ensure the good drainage of the soil, do not let the plant be waterlogged for many days, especially in the rainy season.
Yellow disease, leaf burn: Use Borax solution with appropriate dosage when detecting yellow spots on leaves to avoid spreading.
Cinnamon Worm: This is a very common worm that appears when growing cinnamon trees, they suck the sap to live.
To prevent this, you can use lim
e to brush on the insect-infested part or use a solution made from water with sage powder + neutral soap and then spray water in the early morning on the plants.
Bed bugs, hair clippers, bugs: using a diluted 666 6% solution and then spraying with an appropriate dose will help eliminate these insects.
In addition, during periods of fertilizing and pruning, it is necessary to combine cleaning of the garden, the field of the cinnamon growing area in combination with clearing weeds around the root.
Weeds are home to many pests that can damage cinnamon.
Harvesting Cinnamon Bark
Usually, after about 3-4 years, it is possible to harvesting cinnamon bark in the first crop.
Each sample can give about 500kg of fresh bark, cinnamon trees have a lifespan of up to 80 years, so you can continue to take care of them to harvest for the next years.
There are many ways to harvest cinnamon bark, for example, you can use a sharp knife to cut a circle across the stem first and then cut a lower ring about 40 – 50cm from the top ring.
You just create 2 such rings and then peel off the cinnamon bark on the stem from left to right until completely harvesting cinnamon bark on the trunk.
Or some well-managed places, they peel off half of the bark on the trunk and apply a caring fertilizer that will allow the harvest in a shorter time.
Methods of preservation after harvesting cinnamon
Each locality after harvesting cinnamon bark has different preservation methods. Usually, there are two ways: preserving and laying the cinnamon bark flat or rolling it into a tube. Cinnamon is a very flammable plant with dry skin dry. So it is important to pay attention to transportation.
In addition, the cinnamon essential oil can corrode the iron barrel, so transporting essential oils extracted from cinnamon should use enameled containers. The cinnamon essential oil can also be burned, so each barrel should only be stored up to about 20kg and must be tightly closed to avoid evaporation.
