How to raise the lobular Gardenia jasminoides cultivation methods and matters needing attention

Lobular Gardenia jasminoides is a representative flower plant of eternal love and agreement. It is not only the love placed on people, but also represents the quality of tenacity and nobility. The biggest difference between small-leaf gardenia and other common gardenia is that its leaves are smaller, but not lack of beauty, but more small and lovely. However, the flowering of lobular gardenia is a long process, which needs everyone's care even more.

How to raise the lobular gardenia

1. Soil: gardenia microphylla should choose acidic basin soil with a suitable pH value of 5 to 6. Cultivation soil can choose rotten leaf soil, peat soil or garden soil with half of retting sawdust, and avoid using old wall soil and cinder.

2. Watering: the soil surface of the gardenia gardenia flowerpot can be watered when it is dry, and can be watered to the leaf surface with a spray can at night. If the growth is too prosperous and the internodes are longer, they will not be watered in the evening and will be watered again when the sun comes out in the morning.

3. Fertilization: 3% rotten cake fertilizer was added to the lobular gardenia culture soil as base fertilizer, the alum fertilizer made by cake fertilizer and ferrous sulfate retting was irrigated once a week during the growing season, 0.1% potassium dihydrogen phosphate aqueous solution was irrigated once or twice in bud stage, and the fertilizer was stopped above 35 ℃ in summer and below 15 ℃ in autumn.

4. Lighting: lobular gardenia has good sunlight but can not withstand strong sunlight. It can also grow in semi-shade for a long time, but it must maintain 60% light throughout the day in order to meet its growth needs.

5. Change the pot: when the crown width reaches 28 cm or so, change the potted soil in the family potted gardenia. If it is to change the pot, it is better to plant the soil into the new pot, usually in spring March.

Culture methods and points for attention of Gardenia jasminoides

I. Culture methods

1. Humidity

Sufficient water and suitable humidity are the necessary conditions for the growth of Gardenia jasminoides. In the growing period of the plant, we should pay attention to increase the amount of water, at the same time, foliar spray is also essential, which can increase air humidity. It should be noted that winter watering should be properly controlled, not too much, to prevent freezing in the basin and avoid frostbite.

2. Temperature

The suitable temperature is the guarantee of the growth of Gardenia jasminoides. The best growth temperature of Gardenia jasminoides is from 18 ℃ to 22 ℃. Too high and too low temperature are not conducive to plant growth, so attention should be paid to ventilation and heat preservation.

3. Lighting

Sufficient light is the prerequisite for the growth of Gardenia jasminoides. Gardenia flowers decorate plants that like to shine. Spring and autumn season to pay attention to increase light, gardenia can be raised outdoors; summer to avoid exposure, so as not to cause sunburn; winter should be as for indoor sunshine, control watering, to avoid frostbite.

4. Soil

Lobular Gardenia jasminoides is a typical acid-loving plant, so the pH value should be controlled between 4.0 and 6.5 in soil selection to create a slightly acidic environment for the plant. In addition, the soil must be loose and fertile, good permeability, so that gardenia can breathe smoothly.

5. Fertilization

Fertilization is essential for the growth and flowering of gardenia lobulosa. Especially in the period of vigorous growth, the adequacy of fertilizer plays a decisive role in the flowering of plants. In daily maintenance, bean cake fertilizer and peanut bran can be applied once a month.

II. Points for attention

1. Appropriate amount of fertilizer should be applied

Lobular gardenia likes fertilizer, but it is afraid of thick fertilizer, so it should be used in appropriate amount. The cake fertilizer water rich in phosphorus and potassium was added before the budding stage, and the fertilizer was stopped after budding to avoid burning roots and falling buds with too high fertilizer concentration; cake fertilizer water was applied once a week in the peak growth period, and ferrous sulfate combined application to avoid soil consolidation and salinization.

2. Like the light and be afraid of exposure

Lobular gardenia likes light but is afraid of direct light exposure. After exposure to the sun, the leaves are yellow, sunburned and even fall off, so the flowers should be put in the semi-shade in summer.

How to trim the lobular gardenia

1. Dense branches

But at this time, gardenia itself may grow better, at this time can also be properly trimmed, we should pay attention to styling. Cut off some unnecessary branches, such as loosening in more dense areas, so that some branches will not be difficult to get sunlight, and the photosynthesis of all parts can be carried out better.

2. Thin branches

This kind of branches are originally relatively thin, but the surrounding branches are longer in winter, and if there are diseases and insects, they will certainly appear on these branches, so they can be cut off properly. After being cut off, the surrounding branches can grow better and their nutrients can be fully utilized.

3. Cross branches

Such branches look messy, irregular and affect their appearance, so the crossed branches should be cut as far as possible, which can not only make the whole plant more beautiful, but also make the remaining branches grow better.

What if the lobular gardenia drops its bud?

1. Do not change the basin

Suddenly change their living environment, their previously established balance will be broken, and it is physically difficult to adapt. There is no way for the root to adapt to the new environment at a time, not only may the bud drop, but also the leaves may fall, or even the whole plant may die.

2. Proper amount of water and fertilizer

It is good to choose mild organic fertilizer, such as bean cake, peanut bran and so on. Keep the balance of water and fertilizer.

3. Light should be sufficient.

Gardenia needs light in winter, if it is not exposed to the sun for a long time, it is likely to cause the leaves to have no way to photosynthesis, so it is normal to drop flowers and buds.

4. Iron should be enough.

Iron-deficient gardenia must cause chlorosis, and it can also affect their growth and flowering. This is because only under the condition of slight acid, nutrients can be well absorbed, so an appropriate amount of ferrous nitrate can be added, which can not only prevent yellowing but also make flowers stronger.

5. Proper pruning

Some flower friends will feel that they can't bear to cut off their branches, but too dense branches will certainly affect the formation of flower buds, which is also a reason for falling buds, so it is necessary to prune the branches in time, so that not only the tree shape looks good, but also the flowers will bloom better.

Many friends who have raised gardenia with large leaves are probably tortured to doubt their lives. Lobular gardenia is not so difficult to maintain, which can enhance everyone's confidence in breeding. But waiting for the lobular gardenia to blossom takes a little more patience and time.
