If you don't pay attention to these points in spring, don't let your flowers survive the cold winter but die in spring.

Exercise the adaptability of flowers and plants

reason:

Flowers are accustomed to the warm and windless environment indoors, and it is difficult for them to adapt to the cold wind when they suddenly go out.

practice:

1. Increase ventilation and light transmission half a month before going out, open windows for ventilation during the day, close windows at night, and maintain the room temperature at 6℃ to 12℃. Do this for 2 weeks.

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

Leave the room in batches

reason:

Different flowers have different sensitivities to temperature and different degrees of cold resistance, so potted flowers should be brought out of the house in order.

practice:

1. Flowers with a slightly stronger degree of cold resistance can be taken indoors when the temperature is stable at around 10℃. Such as bicolor jasmine, German primrose, Kalanchoe, He's impatiens, nasturtium, Euphorbia, camellia, sasanqua, azalea, and cycas revoluta.

2. For some flowers that are native to tropical areas and have poor cold resistance, it is best to plant them a few days around Qingming Festival in the south and a few days around Grain Rain in the north. For flowers whose cold resistance is unknown, it is better to plant them late rather than early. For example, jasmine, Milan, hibiscus, poinsettia, jewel orchid, coleus, and green ivy should be brought out of the house later.

Protect from sun exposure and cold wind

reason:

If flowers that are afraid of the sun, like shade, or like semi-shade are exposed to sunlight above 20℃ as soon as they are taken out of the room, they may suffer from sunburn, and the leaves may wilt and turn yellow, or even the whole plant may die.

practice:

1. It is best to choose cloudy weather to bring potted flowers indoors. If you want to bring them indoors on a sunny day, flowers that are afraid of the sun, such as cyclamen, Daphne osmanthus, New Guinea impatiens, and jasmine, need shade as the sun is strong at noon.

2. Plants such as green ivy, azalea, spring fern, asparagus fern, and Clivia should be placed in a place where they can receive direct sunlight in the morning or evening and avoid direct sunlight around noon.

Notice:

Late spring cold snaps or hail are prone to occur in the Yangtze River Basin in spring, which have a particularly strong impact on flowers that have just sprouted and seedlings that have just sprouted. In mild cases, the buds and seedlings can be dehydrated or frozen, while in severe cases, the entire plant can die.

practice:

Therefore, if there is a late spring cold snap or hail after the flowers are taken out of the room (pay attention to the weather forecast), you can move the flowers that have just been taken out of the room back indoors or cover them with plastic film.

Gradually increase watering

reason:

Potted flowers have been accustomed to dry soil throughout the winter. They have just awakened from dormancy in early spring, and the root water absorption function is gradually recovering. If you water them too much at this time, the soil will be too wet, which can easily lead to root rot.

practice:

1. When potted flowers are first brought out of the room, you should spray water on the stems and leaves more often, and still water them less often. The soil in the pots can be slightly moister than in winter.

2. The water temperature for watering should be around 15℃, and the best time is noon. From early spring to late spring, as the temperature rises and the plants grow, the amount of watering can be gradually increased to allow them to gradually adapt and meet their growth needs.

Fertilizer should be diluted

reason:

When the potted flowers are first taken out of the room, the roots of the flowers are still recovering their ability to absorb fertilizer. Applying fertilizer too quickly at this time will do more harm than good, especially applying concentrated fertilizers and raw fertilizers, which will often lead to root burn and death.

practice:

1. When potted flowers are just taken out of the room, it is better to let them grow naturally. Don't rush to fertilize them within 1 to 23 weeks. Wait until they adapt to the environment and then fertilize them according to the situation.

2. For foliage plants and flowers that bloom in summer and autumn, first apply a little bit of liquid nitrogen fertilizer to promote the growth of branches and leaves. As the temperature rises and the plants grow, gradually increase the amount of fertilizer and switch to nitrogen, phosphorus and potassium compound fertilizer.

3. For flowers that bloom in spring and early summer, apply nitrogen, phosphorus and potassium compound fertilizer from the beginning, from dilute to concentrated, from little to much, and stop applying when the flower buds are about to bloom.

Repotting and changing soil

reason:

For potted flowers, especially perennial herbaceous flowers, after a year of growth, the nutrients in the potting soil are basically exhausted, and the roots have covered the pot walls to form a rhizosphere. Watering and fertilizing often go straight from the rhizosphere to the bottom of the pot, and are difficult for the potting soil to absorb.

practice:

1. Flowers that bloom in early spring should be repotted and have their soil changed before being brought indoors in late autumn and early winter, while other flowers should be repotted and have their soil changed when they are taken out of the house in spring.

2. Woody flowers can be repotted and the soil changed every two or three years in early spring. Except for a few flowers such as camellia that can be left bare-rooted and the soil changed, most other flowers should retain 1/2 to 1/3 of the old soil, and properly trim the old roots to promote the growth of new roots.

There are really many things to pay attention to in spring.

Everyone must be more careful when moving the flowers outside!
