Chinese trumpet creeper (Campsis grandiflora) planting methods and precautions explained in detail

Not long ago there was a very popular TV drama called "Spring Breeze Ten Miles Is Not As Good As You", in which a line of poetry was often mentioned: “If I love you, I will never be like that climbing Chinese trumpet creeper, borrowing your high branch to show off myself……” What kind of flower is this Chinese trumpet creeper? Today Qinnong.com will introduce everyone to this Chinese trumpet creeper, as well as its cultivation methods and precautions.

I. What is Chinese trumpet creeper

Chinese trumpet creeper is a climbing vine plant, distributed in the central region of our country. It likes warm, humid, sunny environments. Seedlings are not cold-tolerant. Its growing environment requires fertile, deep, well-drained sandy soil. Chinese trumpet creeper is one of China's famous garden flowers, with a long flowering period. The flowers are funnel-shaped, usually bright red or golden yellow, very vivid after blooming, and also have medicinal value for promoting blood circulation and removing blood stasis, cooling blood and dispelling wind.

II. Planting methods for Chinese trumpet creeper

1. Pot and soil selection

For potted Chinese trumpet creeper, choose a deep, large clay pottery pot or wooden bucket with good permeability for planting. As mentioned above, Chinese trumpet creeper needs a fertile, deep, well-drained soil environment. Soil casually dug up from the street needs to be exposed to the sun, and can be used only after adding base fertilizer, but it is still best to use fertile pine needle soil.

2. Placement environment

Chinese trumpet creeper likes a sunny environment. In a semi-shady environment, the plant grows poorly, with few flowers and pale color. Place the plant as much as possible in a sunny courtyard, balcony, or south- or west-facing balcony, and pay attention to timely ventilation. Do not place the flower pot on a north-facing or enclosed balcony.

3. Water and fertilizer requirements

Chinese trumpet creeper likes a humid environment, is slightly drought-tolerant, and fears waterlogging. Therefore, during the growing period, water frequently to keep the pot soil slightly moist but not waterlogged. From late autumn to the following spring, Chinese trumpet creeper enters dormancy; at this time, keep the pot soil on the dry side and slightly moist.

Chinese trumpet creeper loves fertilizer very much. In addition to adding sufficient base fertilizer to the soil when potting and repotting, after budding, apply a fertilizer mainly based on nitrogen fertilizer once every 10~15 days to promote the growth of branches and leaves. But starting in May, switch to fertilizer mainly based on phosphorus and potassium fertilizer to promote flower bud differentiation and budding. Starting in June, spray a 0.2% potassium dihydrogen phosphate solution on the leaves once every 7~10 days to promote bright and beautiful flowers. After the flowers fade, apply phosphorus and potassium fertilizer 1~2 more times to ensure sufficient nutrients before overwintering. In winter, Chinese trumpet creeper hibernates, so do not fertilize.

4. Pruning

After the brief dormancy in winter, the plant enters a vigorous growth period in early spring, so in early spring promptly cut off dead branches, weak branches, leggy branches, and messy branches, and shorten overly long branches to promote the sprouting of new robust branches.

III. Precautions for cultivating Chinese trumpet creeper

1. Pest prevention

In the water and fertilizer requirements for Chinese trumpet creeper, it is mentioned that Chinese trumpet creeper likes a humid environment, but in a high-temperature and high-humidity environment, Chinese trumpet creeper is very prone to aphid damage. Therefore, during maintenance, it should be ventilated frequently to ensure sufficient humidity, but appropriate cooling is needed to avoid pest damage. In addition, once aphids are found, promptly rinse with clean water or spray pesticide to avoid severe pest damage.

2. Set up support poles

Chinese trumpet creeper is a vine plant. When it grows to a certain extent, support poles need to be set up, and a trellis built for it to climb and grow. At home, Chinese trumpet creeper can be placed at the bottom of a flower trellis, letting it climb and grow along the edge of the trellis. This decorates the trellis and also saves the trouble of setting up supports.

3. Pruning techniques

Usually in early spring each year when buds sprout, for plants more than 5 years old, keep the main trunk 30~40 cm and cut it short, while also trimming the roots, keeping the main root system, and replanting. After potting and sending out new branches, keep only 3~5 new branches on the upper part and cut off all the rest. Control water and fertilizer. After a year of maintenance, it will again be a beautiful and young Chinese trumpet creeper.

The above are the cultivation methods and precautions for Chinese trumpet creeper. Have you found that the cultivation method of Chinese trumpet creeper is very simple?
