Efficient Cultivation Techniques and Daily Care Management Methods for Lilac
Today the Huinong Network editor will take a look with everyone at the cultivation techniques of lilac, to see how this flower with outstanding courtyard ornamental value is planted and cultivated as well as its application in landscaping.

1 Lilac Cultivation Techniques
1.1 Propagation Techniques
1.1.1 Seed propagation. For seed propagation, it is necessary to select seed-bearing lilac plants with a tree age of 5 to 6 years, and to harvest and sow the seeds promptly when the fruit turns purplish-red. If it is not possible to sow in time, the seeds can be stored in fine sand or moist rice bran for about 3 months, then the fruit pulp removed and the seed kernels sown directly.
1.1.2 Cutting propagation. Cutting propagation is generally carried out about 1 month after flowering, selecting flower branches more than a month past flowering as cuttings. The cuttings are required to generally have no fewer than 3 pairs of new buds, and a flower branch length of 15cm is optimal.
1.1.3 Grafting propagation. Branch grafting and bud grafting are the two methods of grafting propagation. In practical application, the most suitable season for branch grafting is autumn and winter; branch grafting requires collecting and burying the scion wood first, and when spring comes, after the branch grafting wood has grown to 80cm, the
grafting work is carried out. To ensure good growth of the scion throughout the grafting process, it is also necessary to first cut off the part 40cm above the ground before grafting, and then proceed with grafting; July is the most suitable period for bud grafting, mostly selecting bud scales about 7m above the ground for grafting, and after grafting is completed, the operation site must be protected, and excess shoots must be removed promptly, so that all nutrients can be concentrated to supply the rapid growth of the scion, in order to ensure the survival rate of grafting.
1.2 Cultivation Techniques
1.2.1 Plot selection. Lilac prefers sunlight, is cold-tolerant and drought-tolerant, and dislikes waterlogging. Therefore, when selecting a planting plot, well-drained and fertile sandy loam soil is needed, but low-lying, damp and shaded areas must be avoided. Facts have proven that when lilac grows in a shaded environment, the branches become slender and fragile, and the flowers produced are few, short and loose; if the planting soil is too barren, growth is slow and flowering is reduced. Therefore, when selecting a planting plot, fertile, sunny conditions with deep soil layers are suitable.
1.2.2 Fertilizer and water management. Lilac does not have excessive fertilizer requirements during its growth process, so frequent and excessive fertilization is strictly prohibited during cultivation, otherwise excessive vegetative growth will affect flower bud formation; therefore, during the growth period, generally no fertilizer or only a very small amount of fertilizer is applied. It should be noted that some potassium fertilizer, nitrogen fertilizer and phosphorus fertilizer need to be applied after flowering; the total amount of potassium fertilizer and phosphorus fertilizer should not exceed 75g, and the nitrogen fertilizer application amount is 25g, to ensure the normal growth and development of lilac. When watering and fertilizing lilac, neither too little nor too much is appropriate, and after watering, the soil should be loosened in good time to avoid fertilizer damage, so that the plant can ensure rapid growth of new buds under conditions of suitable soil temperature.
1.2.3 Pest and disease control. For planting lilac, choose soil with strong drainage, so that the growing environment of lilac is loose and moist. Take effective measures to prevent root rot and the occurrence of pests and diseases. Lilac pests include slug moths, caterpillars, leaf miners, scale insects and giant hornets, which should be controlled promptly and effectively during the growth process.
2 Application of Lilac in Landscaping
In-depth research on lilac cultivation techniques and applications can give full play to lilac's own advantages and increase its scope and intensity of application. Lilac is suitable for growing in environments with sufficient sunlight or half shade; in addition, a relatively moist environment can accelerate the growth of lilac, and it should not remain in waterlogged conditions for a long time. Lilac has the characteristics of drought tolerance, barren tolerance and high-cold tolerance, with extremely strong adaptability and relatively mild pest and disease occurrence. During planting, choose sunny slopes, lawns or roadsides, and it can also be appropriately combined with various other flowers and trees in planting, which not only benefits the growth and propagation of lilac but also improves ornamental value.
Lilac itself carries a rich and fragrant aroma, and in front of windows and outside courtyards it is an excellent planting location; moreover, during planting, various varieties of lilac can be mixed and cultivated to build a lilac viewing garden, or lilac can be cultivated in pots, both of which are good application choices.
Lilac itself has good performance in resisting and absorbing toxic gases; therefore, it can be planted in factory areas, which can effectively improve the ecological environment and overall air quality of the factory area and play a protective role for the natural environment.

Lilac Bonsai Care and Management Knowledge
Lilac (Syringa oblata) is an early-spring flowering deciduous shrub of the genus Syringa in the family Oleaceae. It is drought-tolerant and cold-tolerant, likes sunlight and also tolerates half shade, and is very commonly cultivated in North China, Northeast China and Northwest China. In recent years it has increasingly been moved into pots for cultivation and viewing. Lilac usually blooms in early spring; when potted, with proper management, it can bloom twice, and in the following year the flowering vigor will not decline.
1. Care and Management
Placement location: Lilac likes light, and should usually be placed in a sunny, well-ventilated place. But in summer it needs slight shading; high-temperature sunscald is unfavorable to the growth of potted lilac. In winter, bury the pot outdoors in a sunny spot or move it indoors in front of a windowsill.
Watering: Usually keep the pot soil moist and tending dry, and strictly avoid excessive wetness. In summer high temperatures, water once each morning and evening; after autumn, water less to favor dormancy and overwintering.
Fertilizing: In winter apply decomposed cake fertilizer as a base fertilizer; after spring budding, apply cake fertilizer water once every half month to promote flowering. In summer, fertilizer should also be applied appropriately to favor flower bud differentiation and maintain abundant flowering the following year. After autumn, apply less fertilizer and water; too much fertilizer harms development.
Pruning: During the growth period of lilac, when branches and leaves are too dense, prune promptly, which neither disturbs the tree shape nor hinders ventilation and light penetration. After autumn, when it enters the dormant period, carry out appropriate shaping and pruning, cutting off excessive growth branches, overlapping branches and crossing branches, so that nutrients are concentrated and more flower buds are formed.
Repotting: Repot once every 2 to 3 years. Combined with repotting, prune the root system, remove some old roots and overly long roots, remove old soil, and replace with new culture soil, to favor root development and lush leaves and abundant flowers.
Pest and disease control: Under excessively wet conditions, lilac is prone to root rot; in mild cases growth stops, and in severe cases it withers and dies. Common lilac pests include the house longhorn beetle, which damages branches and trunks; there are also bagworms, slug moths, aphids and others that damage tender branches and leaves. They can be killed by spraying with a 1500-fold dilution of 40% dimethoate.
2. Ornamental Value
Lilac has a graceful posture, abundant purple flowers, and a pleasant fragrance. Using the root stump of small-leaf privet as rootstock to graft lilac into a bonsai produces ancient trunks with flowering branches, each enhancing the other, and it is most worth viewing.
