What soil is good for gardenias in autumn? When is the best time to change the soil and repot garden

Gardenia is a kind of evergreen leaves, white flowers, and when the flowers bloom, it will be accompanied by a faint fragrance, not only beautiful but also smelly, it is a must-have flower at home. In autumn, when gardenias grow most rapidly, nutrient consumption is also relatively large, so when the nutrients in the potting soil are not enough to maintain the growth of gardenias, it is necessary to repot. So what kind of soil is good for gardenias to change pots in autumn?

Is it OK to repot gardenias in autumn? Let's find out.

What kind of soil is good for gardenia to change pots in autumn?

If there is pine needle soil, it is best to mix two percent of the pine needle soil, or directly use pine needle soil to mix granular soil garden soil. It is best to mix a little granular soil with the nutrient soil you bought directly to play the role of air permeability and water permeability. The soil of gardenia is diverse, as long as it is loose, fertile and breathable, and slightly acidic, it is very good.

Is it OK to repot gardenias in autumn?

In fact, the best time to repot gardenias is after flowering, gardenias generally bloom in spring in May and June, after flowering it consumes a lot of nutrients, and it will sprout soon after flowering. Therefore, adequate nutrient supplementation is needed at this time. Whether it is a newly bought gardenia or a gardenia that has been raised for several years, it is more appropriate to change the pot at this time.

At this time, it is the vigorous season for gardenia peanuts to grow, and the seedlings will slow down relatively quickly. After the seedlings are slowed down, there are sufficient nutrients, which can make the gardenia grow more robust.

How do you repot gardenias?

When changing pots, the gardenia pot is turned upside down entirely, and then gently knock the bottom and outer wall of the pot to knock it out whole, if the potting soil is too dry to pour out, you can properly water a certain amount of water. After pouring out the gardenia, the whole plant can be planted in a new pot, and the diameter of the new pot is about 5 cm larger than the original pot.

In addition, after planting a new pot, it should be watered in time, placed in a well-ventilated and bright place, and the branches and leaves can also be pruned appropriately. In the process of changing pots, it is also necessary to pay attention to the fact that the new pot is larger than the original pot and should be filled appropriately, and the soil should be consistent with the previous soil properties, otherwise it will affect its growth.

To sum up, it is about the related matters of gardenia autumn repotting, and I hope to inspire flower friends.

Gardenia in autumn with humus mixed with granular soil, can play a role in air permeability, and as long as it is loose and fertile, good air permeability, and slightly acidic is very good.

Sandy loam. This soil is particularly breathable and can also store water, which provides a particularly good environment for plants to grow and bloom more vigorously.

Gardenias are suitable for repotting in February in the spring and October in the fall.

These two time points are the early stage of plant growth, and the temperature in these two seasons is suitable, and the growth will resume soon after changing the pot, and the activation rate of the burning ruler is higher, and it is not possible to change the pot in the summer high temperature or the rainy season, and it should not be carried out in the flowering period and when there are flower buds, the success rate is very low, and it will also affect the later growth.

Before the gardenia is repotted, you can stop watering, so that it is convenient to take off the pot, directly turn the pot upside down and gently knock the pot, you can take it out with your hand, you need to prune the rotten roots or dead roots after depotting, smear the grass ash at the roots, do a good job of disinfection, and put it in a ventilated place to dry and then you can plant the skin calendar.

How to plant potted gardenias:

The potted soil should be prepared with 40 garden soil, 15 coarse sand, 30 manure soil, and 15 humus soil. Gardenia seedlings should pay attention to watering, keep the potting soil moist, and apply rotting thin fertilizer frequently. It is better to use rainwater or fermented rice washing water.

During the growth period, if you pour ferrous sulfate or alum fertilizer water every 10-15 days (the two can be used alternately), it can prevent the soil from turning alkaline, and at the same time can supplement the soil with iron and prevent the yellowing of gardenia leaves. In summer, gardenia flowers should be sprayed with water once a day in the morning and evening to increase the humidity of the air and promote the luster of the leaves.

Potted gardenias, after flowering in August, only water is watered to control the amount of watering. Before the cold dew in October, move indoors and place it in a sunny place. Watering is strictly controlled in winter, but foliage can be sprayed with clean water.

From May to July every year, when the gardenia growth period will stop, the plant is pruned to remove the top tips to promote the germination of branches, so that the plant shape is beautiful and the flowers are more in the future. Gardenia is mostly propagated by cuttings and striping methods, and can also be propagated by dividing and sowing methods, but it is rarely used.

Cuttings can be divided into spring and autumn cuttings. Spring planting is carried out in mid-to-late February; Autumn planting takes place from late September to late October. Cuttings are selected for 2-3 years of branches, cut into 10-12 cm segments, leave two leaves on the top, cut off half of each, and then insert obliquely into the cuttings, leaving only one section on the soil surface, pay attention to shade and maintain a certain humidity, generally 1 month can take root, 1 year after transplantation.

In the south, there are also those propagated by water cuttings, that is, cuttings are inserted on a disc woven with reed stalks, and they are allowed to float on the surface of the water, so that the lower part of the cuttings can take root in the water and then transplant and cultivate.

Stripping can be done around Qingming in April or during the rainy season. Select the three-year-old mother plant on the annual strong branches, pull them to the ground, and engrave the soil part on the branch, if you can dip 200ppm powder acetic acid on the carved part, and then cover the soil compact, it is easier to take root. Generally, after taking root in the month, it can be separated from the mother plant, and then transplanted with soil in the spring of the next year.

Gardenia is suitable for growing in acidic soil, you can choose the yellow loam soil with rich nutrient content and good drainage for planting, you can also choose the humus soil with rich organic matter content and good air permeability for planting, or prepare the acidic soil suitable for the growth of gardenia peanuts, and you need to loosen the soil regularly to ensure that the soil is loose during the maintenance process.

1. Yellow loam

When planting gardenias, you can choose yellow loam soil for planting, yellow loam soil is acidic, and can keep the soil moist well, in line with the requirements of gardenia growth, but in the maintenance process needs to be regularly loosened to maintain good soil permeability.

2. Humus

There is also the option of planting gardenias using humus soil. The humus contains more organic matter, which can promote the growth of plants, and the soil of humus is loose, not easy to agglomerate, and has good drainage, which can effectively prevent the phenomenon of root rot caused by excessive watering after planting.

3. Mixed soil

Gardenias are suitable for growing in nutrient-rich, well-drained acidic soils, and in order to meet the requirements of gardenias, a mixture of pine needles, humus and river sand can be used as the soil for gardenias.

4. Maintenance method

Gardenia will absorb nutrients in the soil during the maintenance process, and the application of fertilizers and other substances in the planting process will change the acid-base balance in the soil and affect the growth of gardenias, so during maintenance, you can regularly water the diluted vinegar solution into the pot to adjust the acid-base ratio in the soil.
