Tree Rose Knowledge popularization
This article guide:蔷薇月季 tree rose brief knowledge, tree rose knowledge popularization, the following is a comprehensive introduction.
【1】What is the rootstock of tree roses? Generally, the wild native species of roses are used as the rootstock for roses. However, there are more than 200 native species of roses in the world, but there are not many varieties suitable for tree rose rootstock because the conditions required for tree rose rootstock are relatively strict:
A. Long lifespan, not aging, usually able to survive for more than 100 years.
B. Deep and wide root system, and the root system is strong, several times that of ordinary roses.
C. Good disease resistance, can resist nematodes, crown gall disease, etc.
D. Strong growth.
E. Cold-resistant, heat-resistant, water-logged, drought-resistant, and thin-soil tolerant.
F. Good for grafting, rapid healing.
【2】What is a tree rose? Tree rose (TREE ROSE) is also known as standard tree rose (STANDARD ROSE). It consists of two parts:
A. Scion. (The beautiful roses that bloom). Usually the latest popular varieties in the world or the varieties that have been loved for hundreds of years without being eliminated are chosen. There are also super-mini varieties that look like peonies, lotus flowers, or stars, or beautiful varieties as large as faces, or varieties famous for their fragrance, or ever-blooming ones, or uniquely beautiful single-petal varieties.
B. Rootstock. Choose the suitable rootstock variety according to the climate of each region.
Because it presents a standard tree shape, it is called a tree rose.
【3】Will tree roses grow as large as trees? What is the classification of tree roses? Tree roses do not refer to roses that can grow into large trees, but to their tree shape. The trunk height is fixed and will not grow taller, only becoming thicker. Generally, the following classifications are used abroad:
A. Standard Type (Standard Tree Roses) 24", 36", 48" (inches) are commonly used standard heights (referring to the trunk height) abroad. It usually refers to the plant's ornamental height, which is parallel to or slightly lower than the line of sight.
B. Miniature Type (Mini tree roses) Tree roses between 18" and 24" (inches) are called miniatures. Usually grafted with mini roses. Domestically, medium-petaled, multi-flowered varieties are more widely accepted, so we also use medium-petaled varieties to make miniature tree roses.
C. Weeping Type (Weeping Tree Roses) Over 48", because the weeping variety has soft, thin branches with many flowers, it is generally made higher to facilitate growth and viewing! When the whole plant matures, the flowers are as beautiful as a waterfall.
【4】What are the benefits of tree roses? Due to the combination of the advantages of rootstock and scion, tree roses have the following benefits:
A. Easier to plant than ordinary roses.
B. Beautiful tree shape.
C. Easy to manage, organize, prune, weeding, etc.
D. Long lifespan, not prone to aging, strong growth, and more disease-resistant.
E. Easy to configure in gardens, suitable for foreground, middle ground, and background varieties, and can also be used as a standard tree in the garden!
F. Continuous blooming throughout the year with proper management, flower output up to double.
G. Value increases with the years of planting, becoming more beautiful and valuable.
【5】What is the method and timing of making tree roses? To make tree roses, the rootstock must first be cultivated in the field for about a year. After the rootstock becomes thick, the main stem of the living tree rose is obtained by high-pressure or cutting methods. Grafting is carried out from the Winter Solstice to early spring. After about one and a half months, the scion survives. The root suckers of the rootstock are cut off, and the tree rose is placed in the field for management (fertilizing, weeding, pruning, spraying, etc.). It can be sold after about one and a half to two years.
Due to the long production time and labor-intensive process, such beautiful and extraordinary tree roses can be produced.
【6】What are the uses of tree roses?
A. Player collection: Each tree rose is unique and has high collection value.
B. Garden landscape: Tree roses bloom continuously throughout the year and are rare and beautiful, making them the best material for garden landscapes.
C. Engineering design: Planting tree roses of the same variety neatly is widely used in public projects abroad. (T-W) has no severe cold, so the maintenance of tree roses is even easier and worth promoting.
【7】Can a tree rose bloom with different colors? In principle, many different varieties and colors can be grafted onto the same tree rose. However, due to the competition for nutrients, the varieties on the same tree rose must have balanced growth!
【8】Can all rose varieties be used to make tree roses? Of course! However, since tree roses have long ornamental value, we always choose the best varieties for grafting when making them.
【9】Can ordinary roses pruned to have a main stem be called tree roses? Keeping the main bud of ordinary roses and cutting off other branches indeed has the appearance of a tree rose, but it does not have the characteristics of a tree rose. The reason is:
A. Roses are shrubs that continuously renew their branches, so ordinary varieties will age quickly.
B. Roses will keep sprouting buds to prevent aging, which is impossible to remove.
C. When she does not sprout, it means she is aging and will gradually weaken, significantly reducing the number of flowers and having no long-term planting value.
【10】What are the excellent rootstocks suitable for making tree roses?
A. Fortuniana: It is a natural hybrid of Rosa banksiae (Sweetbrier) and Rosa laevigata (Cherry Rosa). It is said to be the most heat-resistant variety. High summer temperatures do not affect it, and it still grows vigorously. Many studies in the world highly recommend this variety. Therefore, our garden will also produce more of this rootstock.
B. Wild Rose Rosa minutifolia: It is a very useful rootstock, with fast rooting, good healing tissue, dense fine roots, and fast growth. Moreover, it has no thorns. I currently like this variety very much. It is still widely used worldwide and is said to have the longest-lived scion of all varieties.
C. Odorata: Odorata is very adaptable to the hot climate of (T-W) and grows very vigorously, with a very high yield. According to the official paper published by (T-W), it can double the flowering amount as a rootstock!
D. Small Cherry Rosa taiwanensis: It is the commonly used small cherry in traditional Chinese medicine! It has超强 growth and is the only native species distributed at low altitudes in (T-W). The old trunk has a bark-like appearance and is quite beautiful and ancient! Among all the rootstock varieties, this one grows the fastest!
E. Dr. Huey: This is the most commonly used rootstock variety in the United States. The two largest rootstock nursery operators in California use Dr. Huey as the rootstock. It is easy to propagate by cutting, has good adaptability to general soil and climate, and maintains a good state during storage and transportation. It is a heat-resistant rose that prefers slightly alkaline soil and is widely used in California and the southern United States (except Florida). Dr. Huey is a modern climbing rose that blooms in spring and has a strong root system. On American websites, people often ask about the red climbing roses seen in the wild or abandoned farms, which are usually Dr. Huey, because the original rose dies, and the rootstock continues to grow with its strong vitality. Dr. Huey is very suitable for the soil and climate of California, has a longer grafting time than other rootstocks, and the largest rootstock nursery operator is in California, making Dr. Huey the most commonly used rootstock in the United States.
F.红花野蔷薇 Rosa minutifolia K2: This is a very easy-to-thicken rootstock and is said to be very resistant to rose "root gall disease" (a tumor-like cancer cell). It grows very fast! The branches are thick and long and very useful! The survival rate of high-pressure or cutting is very high! It is a highly praised strain in Japan! It is cold and heat-resistant and blooms red flowers in spring!
Above is the specific introduction to the popularization of tree rose knowledge, hoping to bring some floral knowledge to flower enthusiasts.
