First, growing habits
Lilac flowers like warm, humid and sunny environment, slightly tolerant of shade, weak growth in shade or semi-shade, few flowers, certain cold tolerance and strong drought tolerance. Not strict with soil, barren, fertile and well-drained soil is preferred, and planting in low-lying areas is prohibited. Water accumulation will lead to disease until the whole plant dies. Transplanting bare roots after defoliation and before germination, and planting them in sunny places with fertile soil and good drainage, mainly distributed in subtropical subalpine, hillside forest edge from warm temperate zone to temperate zone, undergrowth in cold temperate zone and sunny shrubs.
Second, the feeding method
1, watershed selection
Clove plants are relatively large, and the root system is relatively strong, so it is advisable to choose medium-deep clay pots, square pots or round pots. The color of the basin is light blue or light yellow, which can be contrasted with purple and white flowers.
Step 2 plant
Choose robust clove seedlings and plant them in flowerpots in February-March. Prune the root system before planting, leave more fibrous roots, make the root system stretch in the basin, compact the soil, and make the soil and root system closely combine. Cover the soil 2~3 cm below the basin mouth, and then water can be poured.
water
Lilacs have strong adaptability and extensive maintenance methods. As long as you pay attention to weeding in time at ordinary times, pay attention to watering when it is dry, and you can grow smoothly without accumulating water. As for the frequency of watering, there is no strict requirement. Water it when it is dry.
4. Temperature
Lilac likes warm and humid environment, and the climate characteristics of the original producing area belong to the equatorial rainforest climate, which has certain cold tolerance. The optimum growth temperature is 15~20℃, at which time clove grows fastest, but it will stop growing when the temperature is lower than 3℃, which can lead to frostbite and death in severe cases.
Lilacs like sunshine, but are slightly resistant to shade, so when they are maintained, the plants should be placed in sunny places.
5, fertilization
The supply of fertilizer is very important if lilacs want to bloom vigorously. Lilacs don't like big fat, so they can't apply too much fertilizer at ordinary times, so as not to cause the branches to grow white and affect flowering. Generally, before winter, decomposed compost can be applied once a year or once every other year.
6. Change pots and trim them
Lilacs need to change pots every 2-3 years. Take the plants out of the pots, trim the roots, remove some old roots and long roots, and replace them with new culture soil, which is conducive to the development and prosperity of the roots.
Before the clove sprouts in mid-March every year, it is necessary to prune the clove, cut off the branches that are too dense, too thin and sick, and cut off the branches that grow vigorously in the middle to make it ventilated and breathable. If there is no seed left after the flower withers, the residual flower and two buds at the lower part of the ear can be cut off to reduce nutrient consumption and promote the germination of new branches and the formation of flower buds. After defoliation, it can also be pruned once to ensure that the crown is round and beautiful, which is conducive to growth and flowering in the coming year.
7, pest control
The diseases of clove include bacterial or fungal diseases, such as Fusarium wilt, leaf blight, Fusarium wilt, and diseases caused by viruses. Generally speaking, diseases often occur in the period of high temperature and high humidity in summer. Pests include caterpillars, spiny moths, leaf miners, wasps, scale insects and so on. Attention should be paid to prevention and control.
