First, the method of pruning snapdragon 1, topping.
This operation should be carried out at the seedling stage of snapdragon. When the snapdragon grows to about 10 cm, topping treatment is needed to control the plant height and promote the differentiation of branches and leaves, so as to concentrate nutrition and promote more flowering of snapdragon.
Step 2 Trim at ordinary times
When maintaining snapdragon, it is inevitable that there will be some dead branches, diseased branches and too dense branches. At this time, these branches should be pruned in time to avoid wasting nutrients on these useless branches.
3. Prune after flowering
At the beginning, snapdragon needs to consume a lot of nutrition. After the flowers of snapdragon fail and no longer have ornamental value, you can cut off all the branches, that is, cut off the parts on the ground. After pruning, you need to water it once, and after a week, new branches and leaves will basically grow. If you know how to trim snapdragon, you can't forget the usual maintenance!
Second, the maintenance method of snapdragon 1 and proper watering.
Snapdragon is sensitive to water, as long as the soil is kept slightly moist. In spring and autumn, it can be watered 2 ~ 3 times a week; In hot summer, you can water it once a day; Water is watered once a week in winter, and the amount of water needs to be reduced. Don't let the basin soil accumulate water, otherwise it will lead to root rot.
2. Proper lighting
The snapdragon likes full light and is slightly tolerant of semi-shade. In the case of sufficient light, snapdragon grows very neatly, with a large number of flowers and bright colors. But if it is shaded for a long time, the whole snapdragon will grow very tall, with few flowers and dim color. So make sure that the snapdragon can get enough light.
Step 3 control the temperature
If the temperature is too high, it is not conducive to the growth of snapdragon. Snapdragon doesn't like high temperature and high humidity environment, and the flowering temperature is about 15 ~ 16℃. Therefore, in hot summer, it is necessary to carry out proper shading and maintenance in a cool and ventilated place.
4. Rational fertilization
During the growth of snapdragon, thin fertilizer can be added every half month, mainly phosphorus and potassium fertilizer. Because snapdragon has rhizobia and nitrogen fixation, it is not short of nitrogen fertilizer, so it is enough to apply phosphorus and potassium fertilizer appropriately.
Third, prevention and control of common pests and diseases.
The snapdragon is prone to plant diseases and insect pests, and the common diseases are leaf blight, stem rot, gray mold, grass rust and so on. Common pests are aphids, red spiders and whiteflies, which pose a great threat to snapdragon. If not treated in time, plants will gradually wither and die.
After finding the disease, pick the diseased branches and leaves in time and spray special chemicals for prevention and disinfection; When pests are found, they can be killed manually if the number is small, and sprayed with special pesticides if the number is too large.
Conclusion: After reading the above contents, I believe everyone should know the method of pruning snapdragon. Timely pruning and reasonable maintenance will definitely make everyone's snapdragon blossom more and more colorful flowers.
