When is the best time to plant Fraxinus trees for high survival rates?
This article introduces the best time to plant Fraxinus trees for high survival rates and the precautions for cultivating them. Let's take a look together!
Fraxinus trees, also known as green ash or white thorn trees, are a type of tree widely planted in China. This means that the environment in various regions of our country basically meets the growth conditions of Fraxinus trees, and the planting technology is also mature. So today, I will briefly introduce the planting process and cultivation methods of Fraxinus trees.
1. Cultivation Environment
Fraxinus trees prefer warm temperatures, sunlight, salt and alkali resistance, moisture, and fertile soil, with no specific requirements for soil. However, they grow better in neutral, fertile, sandy loam. After selecting the planting site, deeply turn the soil, clean up impurities, pests, tree roots, and weeds, crush soil clumps, level the ground, and then proceed with planting. Of course, for better management, it is also necessary to dig water ditches.
2. Seedling Cultivation
Fraxinus trees are generally sown from the end of March to the beginning of April. Before sowing, we need to conduct germination treatment on the seeds, which includes low-temperature and high-temperature germination methods. After the seeds have germinated, create furrows with a spacing of 10 to 20 centimeters, evenly sprinkle the seeds in the furrows, and then cover them with soil. During the seed germination period, keep the soil moist, usually watering every two to three days and cleaning the field of weeds.
3. Water and Fertilizer Management
After planting Fraxinus trees, ensure thorough watering, then water again after four or five days, and continue watering based on the growth of the trees and rainfall. To help the trees recover quickly, keep the soil moist and water again in the spring of the following year. To promote growth, apply fertilizer scientifically; in the early growth stage, use nitrogen, phosphorus, and potassium fertilizers, and in the later stage, combine with farmyard manure or organic fertilizers. It is important to water after applying chemical fertilizers to prevent fertilizer damage.
4. Pruning and Shaping
Pruning and shaping are important steps in the seedling planting process. Before planting, we need to trim the seedlings, removing weak roots and excess branches. After the trees have taken root, we will prune them to promote the growth of the main trunk and gradually train secondary branches. Once the secondary branches are established, continue training lower branches until the complete tree shape is formed. Even after the tree shape is complete, pruning is necessary to maintain the tree's vigor and promote growth.
5. Pest and Disease Control
The main pests affecting Fraxinus trees are the white ash buprestid, aphids, and longicorn beetles, which can cause significant damage to the trees. To prevent pests, spray lime sulfur solution, and in case of infestation, use methyl thiophanate or carbendazim mixed with insecticides. The most common diseases are brown spot and sooty mold, which can be controlled with Bordeaux mixture and insecticides.
The content I want to share with you today ends here. I believe that after reading the above, you have a general understanding of planting Fraxinus trees, and I hope it can help friends who plant them.
