Exercise the adaptability of flowers and plants

reason:

The flower room has been used to a warm and windless environment. It is difficult to adapt to the cold wind when you leave the room at first.

Practice:

1. Increase ventilation and light transmission in the first half of the month before leaving the room. Open the window for ventilation during the day and close the window at night. Keep the room temperature from 6 ℃ to 12 ℃, and do so for 2 weeks.

2. After two or two weeks, move out of the room during the day. If the temperature is too low at night, move back indoors and move out the next morning. In this way, it can be placed outdoors for 7 to 10 days.

Out of the room in batches

reason:

All kinds of flowers have different sensitivity to temperature and cold tolerance, so potted flowers should come out of the room in order.

Practice:

1. Flowers with strong cold resistance can leave the room when the temperature is stable at about 10 ℃. Such as two-color jasmine, German Primula, longevity flower, he's Impatiens, Golden Lotus, Lingjian lotus, camellia, camellia, azalea, penglaisong, etc.

2. For some tropical flowers with poor cold resistance, it is better to spend a few days before and after Qingming in the South and a few days before and after Gu Yu in the north. For flowers that do not know the degree of cold resistance, it is better to be late than early. For example, jasmine, Milan, Fusang, poinsettia, Zhulan, colorful leaf grass, green rose, etc., it is advisable to leave the room later.

Anti exposure to cold wind

reason:

If flowers that are afraid of sun exposure, like shade and like half shade are exposed to the sun above 20 ℃ as soon as they leave the room, they may cause sunburn, wilting and yellowing of leaves, and even death of the whole plant.

Practice:

1. It is best to choose cloudy weather when potted flowers leave the room. For example, when they leave the room on sunny days, such as Cyclamen, Daphne odora, Impatiens of New Guinea, Zhulan and other flowers that are afraid of the sun, the sun is strong at noon and need shade.

2. Such as green pineapple, Rhododendron, spring feather, asparagus, Clivia, etc., should be placed in a place where direct light can be seen in the morning or evening and can be protected from the sun around noon.

be careful:

In the Yangtze River Basin, late spring cold or hail is easy to appear in spring, which has a great impact on the flowers and seedlings that have just sprouted and the seedlings that have just sprouted. At least the buds and seedlings are frozen, dehydrated or damaged, and at worst the whole plant dies.

Practice:

Therefore, in case of cold spring or hail after leaving the room (pay attention to the weather forecast), the flowers that have just left the room can be moved back indoors or covered with plastic film.

Gradually increase the amount of watering

(author: Nelly, source: Sina blog)

reason:

Potted flowers have been used to the dry soil all winter. They just woke up from dormancy in early spring, and the root water absorption function is gradually recovering. At this time, if you pour water, the soil is too wet, which is easy to lead to rotten roots.

Practice:

1. When potted flowers come out of the room for the first time, spray more water on the stems and leaves, still less water, and the basin soil can be slightly wetter than in winter.

2. The water temperature should be about 15 ℃ and the time should be noon. From early spring to late spring, with the increase of temperature and plant growth, the amount of watering can be gradually increased to gradually adapt to and meet the growth needs.

The fertilizer should be thin

(author: Yasu angi source: poco photography)

reason:

When the potted flower first came out of the room, the fertilizer absorption function of the root was still recovering. At this time, the fierce application of fertilizer was harmful and unhelpful, especially the application of concentrated fertilizer, which often led to root burning and death.

Practice:

1. When the potted flowers just leave the room, it's better to let them grow naturally. Don't be busy applying fertilizer within 1 ~ 23 weeks. Apply fertilizer according to the situation after they adapt to the environment.

2. for foliage plants and flowers blooming in summer and autumn, light liquid nitrogen fertilizer shall be applied first to promote the growth of branches and leaves. With the increase of temperature and plant growth, the amount of fertilizer shall be gradually increased, and the compound fertilizer of nitrogen, phosphorus and potassium shall be applied instead.

3. For flowers blooming in spring and early summer, nitrogen, phosphorus and potassium compound fertilizer shall be applied at the beginning, from thin to thick, from less to more, and the application shall be stopped when the flower buds are about to bloom.

Turning basin for soil

reason:

Potted flowers, especially perennial herbaceous flowers, after a year of growth, the nutrients in the basin soil have been basically exhausted, and the roots grow all over the basin wall and form a root ring layer. Watering and fertilization often go straight from the root ring layer to the basin bottom, but the basin soil is difficult to absorb.

Practice:

1. Flowers blooming in early spring should be turned over for soil before entering the room in late autumn and early winter, while other flowers should be turned over for soil when leaving the room in spring.

2. Woody flowers can be turned into pots and replaced with soil in early spring every two or three years. Except that a few flowers such as Camellia can be replaced with bare roots, most other flowers should retain 1 / 2 to 1 / 3 of the old soil, and properly trim the old roots to promote new roots.

There are really many places to pay attention to in spring,

We must pay more attention when we move out the flowers!
