Ligustrum lucidum is a semi-evergreen shrub of Ligustrum in Oleaceae, and it is a hybrid of Ligustrum lucidum and Ligustrum lucidum in Phnom Penh. As a hybrid seedling, Ligustrum lucidum with golden leaves not only has excellent ornamental effect, but also has bright colors, and is usually used for landscaping. Ligustrum lucidum not only has ornamental function, but also has certain medicinal value, so it has a wide market value and is also welcomed by many seedling growers. So how high can Ligustrum lucidum grow? How to plant and maintain Ligustrum lucidum with golden leaves? Let's get to know each other.
How high can Ligustrum lucidum grow?
Ligustrum lucidum is a small tree, so this plant won't grow very tall. Usually it can grow to 1 meter to 2 meters and is 2 meters tall.
How to plant and maintain Ligustrum lucidum with golden leaves?
At present, many gardeners skillfully use Ligustrum lucidum as rootstock to make Ligustrum lucidum have higher ornamental value, and then cultivate it by grafting. The key points of planting and maintenance are as follows:
1, rhizome
It is best to use Ligustrum lucidum with a DBH of more than 3 cm as rootstock. Rootstocks with large specifications have more nutrient accumulation, high grafting survival rate and fast growth of grafted seedlings, which is more conducive to rapid prototyping.
2. scion
It is necessary to choose the scion with strong branches around the crown, small and uniform branches and no pests and diseases. It is better to pick and choose, which is more conducive to survival. If you can't use it to pick scions, store them in a place with low temperature and relatively high humidity, cut off the leaves and leave only the petiole.
3. Time and method of grafting
Spring and autumn are the most suitable seasons for grafting.
Grafting in spring: When the juice begins to flow from March to April, the time from grafting to survival is the shortest and the survival rate is high. Splitting, cutting, abdominal and subcutaneous transplantation can be used. Subcutaneous transplantation is a common transplantation method in nursery in recent years because of its fast speed and high survival rate.
Autumn grafting: Generally, bud grafting is adopted. T-bud grafting is carried out in June-August, and bud grafting is carried out in August-September in late summer and early autumn. T-bud grafting is the most commonly used method because of its simple operation and high survival rate.
4. Maintenance after grafting
(1) rootstock cutting: After the bud grafting survives, the rootstock branches above the bud grafting are cut off, which is called rootstock cutting. When budding in summer and autumn, the anvil should be cut before budding in the following spring. For bud grafting in early spring and summer, the rootstock can be cut off immediately during grafting or after the bud grafting survives. The incision of the anvil is 0.3 ~ 0.5 cm above the bud, slightly inclined to the back of the bud.
(2) Erection support: The grafted scion is very delicate, and it is often easy to break when encountering strong wind, resulting in losses. Branchlets can be erected on both sides of the scion for protection.
(3) sprouting: in order to concentrate the healing of nutrient supply interface and promote the healthy growth of grafted shoots, sprouting strips and sprouting strips on the rootstock should be cut off at any time.
(4) Daily management: After the scion survives, it should be stocked in the first year: let it grow naturally without pruning. Make it grow vigorously and accumulate nutrients. In the following year, MengMeng began to trim his head and make a normal trimming style. In this way, the diameter of the spherical crown can reach more than 1 m after autumn.
Generally speaking, the grafting of Ligustrum lucidum has improved the trunk height and disease resistance, and the ornamental effect is more prominent when it is used for greening and landscaping. Therefore, it is suggested that growers should master the grafting and management methods of Ligustrum lucidum and do a good job in daily planting and maintenance in order to plant better Ligustrum lucidum.
