When to repot the sunflower and how to change the pot of the sunflower

It is best to repot the sunflower because the pot is too small to coordinate with the plant and will cause its growth to be inhibited.

The repotting time of the sunflower should be carried out in the late March to the middle of September every year, and if it is a greenhouse culture, it can be repotted in all seasons.

After repotting, the pot should be placed in a slightly shaded place, so that it can be better relieved and avoid water loss and wilting.

The general steps of repotting the sunflower are to take out the plants, replace the potting soil, repot them, and maintain them after potting.

When taking out the plant, you can gently tap the surrounding of the pot with your hand, so that the roots will be affected by ** and separate from the pot. Turn the pot upside down, gently hold the plant with your hands, and tap the bottom of the pot so that the plant can come out.

After removing the plants, prepare the potting soil again, choose a pot of the right size, put tiles at the bottom of the pot to promote drainage, and then add ceramsite as a water filter, and then put fertilizer and soil in turn. Put a part of the soil first, and then put the roots of the plant in, pay attention to the root system to stretch well, and then continue to fill the soil. After filling the soil, it is necessary to pour it through the water once.

It should be noted that the loose-tailed sunflower will be combined with pot change to propagate the branches. Dividing is relatively simple and is mainly carried out around April.

Because the growth of the plant is not coordinated with the pot, it is necessary to change the pot to ensure the growth, so that the roots will not be unable to absorb nutrients. The four seasons of greenhouse farming are OK and there are no restrictions. However, under normal circumstances, the time is generally selected from late March to mid-September every year, and the climate is relatively mild and suitable during this time.

1. Slowly take the plants out of the original pot and gently pat the sides of the pot with your hands, so that the inside will vibrate, which can help the plants to separate. Loosen it up and hold the plant with one hand and tap the bottom with the other hand so that the plant can be detached.

2. Prepare a suitable flower pot, which should be a little larger than the original. The bottom is padded with tiles, which can promote the effect of drainage. Then add ceramsite, nutrients and half of the soil inside, and then put it in it, fill the surrounding area with soil, gently compact, pay attention to the root system at the bottom to be comfortable, can not be folded, otherwise it is not conducive to rooting.

3. After the end of the filling, the watering is permeable, which can play the role of fixing the roots, and is placed in a cool and astigmatism place for maintenance, and the plant can be converted to normal maintenance after adaptation.

Sunflower comes from Madagascar and belongs to the palm family. Generally cultivated in the living room and in the more spacious hall. If the growth is good, change the pot once every one to two years. Otherwise, the pot is small and the plantlets are disproportionately large. Not conducive to viewing.

It is best to repot the sunflower in April, and choose a slightly larger pot when changing the pot. There should be holes at the bottom of the pot, which is conducive to loose and breathable roots of sunflower, and an appropriate amount of compound fertilizer and garden soil should be prepared fully and evenly for later use. Stop watering for about a week before depotting, dry the potting soil, and then put the pot on the ground, not cement and brick, so as not to damage the pot, put it on the ground and turn around to pat the edge of the pot, so that the pot is isolated from the pot soil, and then grab the stem of the sunflower with gloves and gently lift the book out of the pot.

Then put it in a large pot with soil already filled and straighten the plant! The surrounding soil is compacted and watered, and the light is dispersed and maintained, until the new leaves germinate, so that the light can be slowly increased.

The family of sunflower is very easy to raise, and it purifies the air, and the ornamental value is also high. A lot of the same is decades! Be sure to remember to repot it, otherwise it will not be in a good state, because during the repotting period, you can fertilize the loose soil and dry brother section of the loose-tailed sunflower.

<>1. The water should be controlled for a week before changing the pot, and when the soil is slightly dry, when the jujube is late, knock the pot wall with your hands to get the sunflower out of the pot. Gently remove the old soil on the periphery of the mound with your hands, properly repair the old roots that are exposed, and then prepare the flower pot of the new stool Li Li, sit the loose tail sunflower in the flower pot, fill in some new soil and gently compact. Water the sunflower once permeable, move the potted plant to a cool and ventilated place to slow the seedlings, usually observe the soil surface whitish, dry and watering permeable, and gradually increase the light after changing the pot for a week.

2. After the success of the seedlings, the plants should be given sufficient scattered light, the light in winter is warm and soft, and it can be sunbathed all day. The watering of the sunflower should follow the water supply principle of "seeing the dry and seeing the wet", and the flowers can be watered with nitrogen, phosphorus and potassium balanced fertilizer and water every half a month in the peak season of plant growth to promote the vigorous growth of the plant.

Soil conditions: Sunflower is suitable for planting in slightly acidic or neutral soils rich in humus and highly permeable. Proper watering:

It needs to be watered twice a day during the peak growth period. Pest control: The control of whitefly can be sprayed with 200 times the solution of Caltex dichloride.

Precautions: Repot once every 2-3 years.

1. Soil conditions

Loose-tailed sunflower is suitable for planting in humus-rich, loose, deep, and highly permeable slightly acidic or neutral soils, and if it is potted, it can be prepared with a mixture of humus, peat soil and perlite, and a small amount of basal fertilizer is added to it.

2. Water properly

Watering sunflower should grasp the principle of seeing dry and wet, watering is watering thoroughly, in the vigorous growth period needs to be watered twice a day, in case of rainy weather to control watering, high temperature in summer to regularly spray water to the foliage, not only to keep clean, but also to reduce the temperature.

3. Pest control

The breeding environment is too closed or poorly ventilated, and the sunflower will be infested by whiteflies and red spiders, among which the control of whiteflies can be sprayed with 200 times of Caltex dichloride, and the control of red mites can be diluted with 3000-5000 times of tachycarone 20% wettable powder.

4. Precautions

When the winter sunflower enters the dormant period or semi-dormant period, it is necessary to cut off the diseased, dry and overgrown branches in time to avoid the waste of nutrients, and at the same time change the pot once every 2-3 years, and place the plant in a semi-shaded environment after changing the pot.
