How to trim Milan flowers

When I was reading, I learned a song: there is a basin of Milan in front of the teacher's window, and the little yellow flower is hidden among the green leaves. It does not blossom for spring, but silently sprinkles fragrance all over people's hearts. When you see Milan, you will think of your teacher and those relatives and friends who gave silently in the process of growing up. So I have a special affection for Milan. Today I would like to share with you:

1. Pruning methods of Milan flowers

Spring is a good time to prune Milan flowers, but summer is not suitable because of the high temperature. Pruning should be carried out outdoors, cutting off dead branches, disease and insect branches and weak over-dense branches to enhance ventilation and light transmission. Pruning is generally not needed during the growing period, and short and long branches can be cut when the tree is unbalanced.

Milan should start pruning and shaping from the seedlings, keep a section of the trunk 15 to 20 meters high, and branch and prune the trunk above 15 meters to make the plant plump. The lower branches of perennial plants often grow old and die, which requires a short cut in the high temperature season every other year to promote the sprouting of new branches in the lower part of the main branch.

When the plant growth is too tall and out of harmony with the placement space, the excessively high branches can be cut short, or they can be combined with reproduction to carry out the "high-altitude striping method" (overlong branches with lead wire, through the method of bending and binding, compress to the lowest position), make it dwarf, Milan's horizontal growth will look better. Apical buds and flower buds should be removed properly when pregnant buds, but it is generally not suitable for pruning at high temperatures in summer.

II. Overwintering Management of Milan Flowers

Milan is of tropical origin and is not resistant to low temperatures. Generally, during the period from Frosts Descent to the Beginning of Winter, you will move into the room and put it on the sunny windowsill or tabletop. The indoor temperature should be kept at 8 ℃ 10 ℃, with no less than 5 min. If the temperature is too high, tender shoots will grow, reducing adaptability and cold resistance. The plant should not be close to the stove or hearth; the temperature and humidity can be adjusted by using a plastic cover, but one or two cracks need to be cut at the top of the cover to avoid excessive temperature and humidity and affect normal growth.

The basin soil should be watered when it is dry, but not fertilized. When the weather changes suddenly and the indoor temperature drops below 5 ℃, special measures should be taken to keep warm, such as moving the potted flowers under the table at night, covering the table with cloth curtains and padding grass curtains to keep warm; you can also cover the pots with plastic bags and remove the cover curtains the next day when the sun comes out and move the potted flowers back to the same place from under the table. Where you put it in Milan, you should not open windows for ventilation, so as not to damage the plants by the cold wind.

Third, the culture methods of Milan flowers:

Milan is a subtropical tree species. Like the mild and humid environment. Use peat, rotten leaves and sandy soil to plant. Families can use (old) gentleman orchid soil and plain noodle sand soil mixed with cooperative cultivation soil. Do not use the basin too large, do not add alkaline fertilizer to the soil, and pad the drainage layer at the bottom of the basin. After the seedlings are planted, they are first maintained in the shade. Spray water on the leaves and around the ground every day when the sky is dry to keep the environment moist. Wait for the new leaves to grow and then move to the shade, and then gradually adapt to the strong light, the flowers are more fragrant. The flower seedlings on the pot in spring will start to be fertilized before and after the Beginning of Autumn. It is better to use thin organic liquid fertilizer.

From the second year, organic liquid fertilizer is applied every 20 days in the peak growing season. If the mixed solution of 0.1% urea and 0.2% potassium dihydrogen phosphate can be applied alternately, the flowers and leaves will be more luxuriant. The basin soil should always be kept moist, do not miss the drought, but do not accumulate water for a long time. If it is placed indoors to strengthen ventilation, it should be rotated to the outside in about 15 days. Sufficient sunshine should be seen when moving into the room in winter, and the minimum room temperature should not be less than 8 ℃. Control water and ban fertilizer, and pay attention to the opening and closing of doors and windows to avoid cold wind and smoke pollution. Prevent the harm of shell insects and coal fouling disease. In North China, after the dry wind from late April to early May, it will be moved to outdoor maintenance. Milan can change the basin every two years.

Milan is one of people's favorite flowers and plants, and the flowers are in full bloom in season. As an edible flower, essence can be extracted. Such as Milan scented tea. Milan potted plants can be displayed in the living room, study and porch, fresh and elegant, comfortable. Milan is also an excellent scenic tree in the southern courtyard.
