How to prune gardenia and how to propagate gardenia (cutting method)

Gardenia leaves bright green, evergreen, large white flowers, aromatic fragrance, but also has a certain shade resistance and anti-toxic gas ability, can be planted in pieces or configured in the forest edge, court front, court corner, roadside, or balcony greening, potted flowers, cut flowers or bonsai is also very suitable, but how to prune it and how to reproduce it, let me introduce it to you.

How to trim gardenias

1. Bud wiping and tillering

The meaning of bud wiping is to cut off the buds or buds that have just sprouted. To eliminate sin means that a branch appears in the wrong place, and then we cut it off. The purpose of bud removal and degerming is to reduce nutrient consumption and improve the light and water conditions of spiders.

2. Pinning and pruning

Topping is to cut off the top 2~3cm of gardenia buds, which can promote the growth of new branches. Cutting is the process of cutting short the branches of a plant as they lignify.

3. Leaf picking and flower picking

This is also the best understanding of the point, we only need to grow too dense gardenia when the appropriate amount of cutting off some leaves, so that the whole plant can increase the light transmission and ventilation. Picking flowers means cutting them off in time after they wither, so as not to consume more nutrients.

How to breed gardenia (cutting method)

1. Time of cutting

If you use hydroponics, you can actually do it all year round, because you can create the environment and temperature indoors. The best time is from early June to early August and from early October to mid-November. This time can be planted in soil or hydroponics. These two periods are called summer and autumn respectively. The temperature of summer and autumn is relatively high, and it is easy to root. Winter is a little worse.

2. Tools needed

A container for water (glass, any bottle, OK, mineral water bottle), preferably of transparent glass, so that the clarity of the water can be seen, so that it can be changed at any time. Root growth can be observed. If the container is large, it can be inserted into the bottle like a flower arrangement. If it is too small, it needs to be fixed.

3. Branch selection

This step is actually the most important, this step is done well, it is half successful, gardenia branches to choose 1-2 years old branches, too tender easy to rot, too old and not easy to root. Skin color bright green, no pests, grow strong is the most basic conditions: gardenia varieties, common gardenia have "big gardenia","egg leaf gardenia","small gardenia","narrow leaf gardenia","spotted leaf gardenia" and so on, I personally prefer "big gardenia", open flowers big and white, rich aroma, so I in a pile of flowers, flowers in the middle and young gardenia trees in the selection of the new two years of big gardenia branches for cutting. It is recommended to select several branches together for hydroponics.

4. Operation

The selected branches should generally have three nodes, remove the leaves on the bottommost nodes, leave only 1-2 leaves on the upper two nodes, reduce transpiration, facilitate photosynthesis, leave 1-2 cm downward at the bottom nodes to cut into horseshoe shapes, if the branches are selected in the middle, leave 1-2 cm at the upper nodes to cut flat. Root systems grow from bevelled cuts. Insert the cut branches into the prepared bottle. Because it is hydroponic, do not need to consider the cultivation medium, only need to put water in the container, change at any time, so as not to cut rot.

5. Precautions

The container should be placed in a place where the light is bright and there is no direct sunlight. The clean water only needs to be replaced once a few days. The specific time depends on the specific situation. It is not necessary to change too frequently so as not to get new tender roots. If it is June-July cuttings, the average temperature is 22-26 degrees, and roots can grow in 2 - 4 weeks.

6. Transplantation

When the root system reaches 7 cm, it can be transplanted. Seedling transplantation can be carried out as usual, holding seedlings with one hand, spreading roots gently on the medium with the other hand, holding plants to fill soil, wetting the medium with soaking basin method, and placing in a ventilated place with bright light and no sun irradiation. The soil should be kept moist, and after 3 pairs of new leaves grow, they can be moved to a semi-sunny place before fertilization.

Why don't gardenias bloom?

1. Improper water and fertilizer: Excessive water and fertilizer of Gardenia will cause excessive plant growth, affect flower bud formation, and lead to no flowering or few flowering.

2, light discomfort: Gardenia likes shade, pay special attention to too strong summer and too weak winter light, too strong or too weak light will affect the flowering of gardenia.

3. Alkali soil: Gardenia likes acidic soil, and high salt and alkali content in soil will cause plant yellowing, which will eventually affect flowering.

4. No pruning: A large number of miscellaneous branches of mast flower consume a lot of nutrients and the branches are too dense to affect photosynthesis are important reasons for not flowering.

5. Pest damage: I believe everyone can understand that the mast flower does not bloom due to pest damage, because serious pests and diseases will inevitably cause flowers to fall and accumulate.

What about yellow gardenia leaves?

1. Gardenia leaves yellowing due to excessive watering

Gardenia due to excessive watering caused by yellow leaves performance for young leaves dark yellow and dull, old leaves no obvious change, branches small yellow green, new shoots atrophy is not long, indicating excessive watering. Remove the flowers from the pot and place them in a cool, ventilated, self-drying soil mass before putting them back into the pot.

2. Gardenia leaves yellowing due to drought

The yellow leaves of water shortage are not the same as the yellow leaves of water shortage. The yellow leaves of water shortage are withered and dried at the tips or edges of the leaves. The old leaves are withered and fallen from bottom to top, but the new leaves grow normally. Pay attention to watering when watering enough, watering can be thoroughly.

3. Gardenia leaves yellowing due to direct sunlight

Strong direct sunlight to some shade-loving flowers (such as hanging orchid, jade hairpin, etc.), easy to cause flower leaf tips, leaf margins withered, leaves sunny part of the yellow spots. Move to the shade.

4. Gardenia leaves yellowing due to lack of light

Long time shade environment, leaves do not get enough sunlight, can not form chlorophyll, the whole plant leaves turn yellow and then fall off, supplement light can avoid this disease.

5. Gardenia leaves yellowing due to excessive fertilization

Fertilization too much or too much concentration caused by yellow flowers, performance in the new leaf tip appears dry brown, general foliar fertilizer thick and dull, and concave and convex do not stretch, old leaves yellow fall off. Fertilization should be stopped immediately, and serious parts of fertilizer should be washed with a lot of washing.

6. Gardenia leaves yellowing due to lack of fertilizer

Gardenia due to lack of fertilizer caused by yellow leaves in the performance of young leaves pale color, yellow or light green, while the old leaves are more normal or gradually from green to yellow. Check basin soil, if there is dry phenomenon should change soil, usually thin fertilizer and timely irrigation of some alum water.

Gardenia in the growth process, often appear yellow leaves, the reason is mostly due to cultivation management disorders caused. However, yellowing is not the same, should carefully observe and analyze the reasons, correct, so that gardenia can grow healthily. This way, they can produce better flowers.
