Araucaria is an economical and practical evergreen tree species, commonly used for landscaping and shelter belts. To meet market demand, propagating Araucaria is an important step. However, many people are not familiar with the propagation methods and precautions of Araucaria, leading to failed propagation or low survival rates. This article will introduce you to the propagation methods and precautions of Araucaria, helping you easily master propagation techniques and make it easier to succeed in growing healthy Araucaria.
Seed Collection and Storage
Between October and November, Araucaria flowers and bears fruit, forming hard cones. After the cones turn brown, use pliers or manually twist them off. After collecting the cones, place them in a ventilated and dry environment, and let them dry for 1-2 months before opening the cones to remove the seeds inside, clean them, and dry them again. The best storage environment is in a cool, ventilated place, placed in a sealed bag, keeping them dry.
Preparing Seedling Pots
Select 4-inch seedling pots with drainage holes at the bottom to prevent water accumulation from causing seed rot. Add breathable sand or gravel at the bottom of the pot, then add fertile soil to meet the initial growth needs of Araucaria.
Sowing
The seeds of Araucaria are very small, and there are usually hundreds of seeds in each cone. When sowing, evenly scatter the seeds on the seedling pot without covering them with soil. Then compact the soil to ensure the seeds are in contact with the soil.
Irrigation
After sowing, gently spray water with a sprayer to moisten the soil. Do not overwater to avoid washing away the seeds. Spray water once in the morning and evening daily.
Light and Temperature
Araucaria requires plenty of sunlight and a warm environment to grow. In the first few weeks after sowing, place the seedling pot in a location where it can receive sunlight outdoors or indoors. After sowing is complete, place the seedling pot in an environment around 25 degrees Celsius to allow the seeds to germinate as soon as possible.
Fertilizer
In the early stages of growth, Araucaria needs sufficient nutrients. Apply a fertilizer solution at 1/4 concentration once a month to promote the growth of the seeds.
Transplanting
When the seedlings reach about 4 inches in height and have 2-3 true leaves, they can be transplanted. Move the seedlings to a larger pot to allow better development of the roots.
Care
Araucaria needs to maintain appropriate humidity and temperature. In the early stage of growth, spray water once in the morning and evening daily to keep the soil moist. The temperature should be kept between 20-25 degrees Celsius. At the same time, pay attention to avoiding natural disasters such as strong winds and sudden rains that may damage the seedlings.
Garden Transplantation
Araucaria can be transplanted when the seedlings grow to more than 40cm. First, dig out soil to a fixed depth of 3-4 inches, then dig out the entire Araucaria plant. Transplant the Araucaria to new land, bury its roots deep in the soil, then compact the soil and water to ensure the roots are in contact with the soil.
Survival Rate
The survival rate of Araucaria is affected by many factors, including humidity, temperature, fertilizer, and transplantation. The way to improve the survival rate is to maintain a suitable environment and pay attention to cultivation details.
Pest and Disease Control
Araucaria is susceptible to infections by fungi such as thousand-layer cake moss. Fungicides and insecticides should be used to control the plants. At the same time, regularly inspect the plants and promptly address any issues found.
Avoid Excessive Pruning
Pruning of Araucaria should not be excessive because they grow slowly, and excessive pruning will affect their growth rate and shape. Only regularly prune dead leaves or dry branches.
Regular Fertilization
Regular fertilization helps the healthy growth of Araucaria. In spring and autumn each year, apply high-nitrogen and high-phosphorus fertilizers respectively to enhance the immunity and disease resistance of Araucaria.
Note the Growing Environment of Araucaria
Araucaria prefers to be in an environment with ample sunlight and good ventilation. When planting, choose soil suitable for Araucaria growth and manage fertilization and moisture according to actual needs.
These are the methods and precautions for propagating Araucaria. As long as you follow the steps above, from cone collection to the growth process, and adhere to the details, you can successfully propagate healthy Araucaria. We hope this article is helpful to you and wish you success in propagation!
