What are the methods and precautions for cultivating lilac flowers in Europe
Xiaobian will explain to you the cultivation methods and precautions of European lilac flowers. It will definitely help you. Let's learn about it together!
Syringa vulgaris is a shrub of great ornamental value and is deeply loved for its rich aroma and elegant inflorescences. If you want to successfully cultivate European lilac flowers, you need to master its growth habits and key maintenance techniques. The following is a detailed explanation from five aspects: soil selection, light management, water and fertilizer control, pruning and shaping, and pest and disease control.
###1. Soil and environment require European lilac flowers to be more adaptable, but neutral or slightly alkaline soil (pH 6.5-7.5) with loose, breathable and good drainage is better. It is recommended to choose a higher terrain for ground planting to avoid stagnant water; for potted plants, you can mix legus soil: garden soil: river sand in a ratio of 4:4:2, and add a small amount of bone meal as the base fertilizer. Before planting, the soil needs to be dug deeply by 30-40 centimeters and mixed with decomposed organic fertilizer (such as sheep manure) to improve soil fertility. I like a sunny environment and need at least 6 hours of direct light every day. It has extremely strong cold resistance (can tolerate-25℃), but persistent high temperatures above 35℃ in summer may shorten the flowering period. It is recommended to plant in an east-facing position with slight shade in the southern region.### 2. Scientific watering and fertilization-Water management: - -1. During the growing period (spring to early summer), keep the soil slightly moist, dry 2 cm of topsoil and then irrigate it with water. Increase water appropriately during flowering period to avoid early wither 3. Spray on leaves in the morning and evening to moisturize in the high temperature season in summer 4. Gradually reduce watering after September, and keep the soil dry during the winter dormant period-Fertilization strategy: --Early spring germination period: Apply high-nitrogen compound fertilizers (e.g. 20-10-10) Promote branch growth-flower bud differentiation period (April): Switch to phosphorus and potassium fertilizer (e.g. 15-30-15), and irrigate roots once every two weeks-topdressing after flowering: decompose cake fertilizer, water or organic liquid fertilizer to restore tree vigor-Note: Avoid fertilization during flowering to prevent buds falling; newly planted plants do not need topdressing within half a year ###3. Scientific pruning of key points of pruning and shaping can extend plant life by more than 20 years: 1. - - Post-flowering pruning- -(May-June): Cut off the remaining flower ears in time and keep the 1-2 pairs of bud points below 2. - - Winter plastic surgery- -(December-February):
- Cut dense branches and crossed branches, and keep 5-7 main branches
- Shorten 1/3 of the long branch to stimulate the germination of lateral branches
- Renewal of old branches: shrink 1/4 of the aged main branch to the strong lateral branch every year. - - Special treatment- -: For the grafted seedlings, remove the sprouts of the rootstock in time ##4. Key points of reproduction technology 1. - - Cutting propagation- -(success rate 60-70%):
- Select semi-lignified shoots in June and retain 2-3 knots
- Dip the base with 1000ppm indole butyric acid rooting agent
- Insert it into a matrix of perlite: vermiculite =1:1, maintaining 85% humidity 2. - - Layered propagation- -(success rate above 90%):
- In spring, the low branches are ringed by 1cm and buried in the soil for fixing
- The mother plant was separated and transplanted in the spring of the following year. Attention should be paid to sowing and breeding: Seeds need to be stored in the sand at a low temperature of 4℃ for 60 days to break their dormancy ##5. Integrated pest control-Common diseases and countermeasures: - - -Powdery mildew-: Spray 25% triadimefon 1500 times at the beginning of the disease, and continuously 2-3 times- -Brown spot disease- -: Remove diseased leaves, spray 70% mancozeb 600 times solution- - -Root rot-: Use 50% carbendazim 800 times solution to irrigate roots during soil change-Pest management: - -1. Aphids: Spray imidacloprid with 2000 times liquid, focusing on the back of leaves. Red spider: Diphenhydrazate suspension 3000 times solution, once a week for 2 weeks 3. Borer: After discovering the hole, inject DDVP stock solution and seal it ###Notes supplement: 1. The best time for transplanting is after falling leaves in autumn or before germination in early spring, transplanting with soil balls. Saplings in northern China need to cultivate soil for cold protection during winter, and mature plants can naturally winter 3. The soil of the potted plants is changed every 2-3 years, and 1/3 of the old roots are removed. Avoid mixing with shallow-rooted plants such as asty trees to prevent nutrient competition 5. Old plants with reduced flower quantity can adopt the "root-cutting and rejuvenation method": cut roots in a ring 60cm away from the main stem, and fill in new nutrient soil. Through the above systematic management, European lilac flowers can enter full flowering period after 3-4 years of planting, and the annual flowering period lasts for 20-30 days. The key is to grasp the annual management rhythm of "protecting water in spring, shading in summer, controlling fertilizer in autumn, and pruning in winter" to achieve the best viewing effect.
