Elm and osmanthus can't be grafted. Elm belongs to elm of elm family and osmanthus belongs to rhinoceroseae family. They belong to different families and have a long genetic relationship. They are difficult to be grafted, even if they are grafted, they are difficult to survive. If there are good elm stumps at home, they can be grafted to similar families, such as elm, peach, apple and apricot, which are relatively easy to survive and relatively high healing. If osmanthus wants to be grafted, it's best to choose the seedlings seeded with seeds. The effect is the best. You can also choose Ligustrum lucidum, tassel, Ligustrum lucidum, white wax, water wax and small wax, which have their own advantages and disadvantages.
1. Ligustrum lucidum: using Ligustrum lucidum as rootstock, the disadvantage is that the interface is easy to be not firm, and easy to break. The corresponding grafting method is to reduce the interface, and the interface should be long..
2. Tassel tree: it often has the defects of thin top and thick bottom, so it is necessary to strengthen the management of fertilizer and water, so as to speed up the growth speed, and cut off the over dense branches and Cross branches.
3. Water wax: use water wax grafting, will appear under the fine situation, need to carry on the reasonable fertilization, pay attention to the frequency of changing basin not too frequently.
