Gardenia likes acidic soil, and the pH value of the soil should be controlled at 5-6. Humus soil or weathered pond soil is usually used. Iron-deficient or alkali-containing soil is not suitable for planting.
Planting is generally carried out in March-April, and some branches and leaves are cut off to reduce water evaporation.
Want to plant a perfect bonsai as soon as possible, try to choose adult plants. It takes 3~5 years from the seedling stage, and the branches of the plant can be strong, which has good ornamental value.
Processing will process the prepared branches, climb the thick branches with brown silk, and trim the remaining thin branches. The whole attitude modeling can also be carried out after flowering or dormancy, which will not have any influence on the growth of plants.
Gardenia can be made into curved dry type, inclined dry type, straight dry type and cliff dry type. There are few materials and limited space at home, so it is common to watch small and medium-sized bonsai.
Gardenia in protected management places likes light, but it can grow in semi-shade, but its branches are slender and there are few flowers. Therefore, except for proper shading and dormancy in July and August, normal maintenance in the sun at other times can ensure lush foliage.
The watered gardenia needs a lot of water to grow. The soil in the pot should be wet and not dry, but there should be no water in the pot. When it is hot in summer, besides watering, we should often spray water on leaves and the ground, or put bonsai beside the pool to increase the air humidity.
Fertilization began in April, and pancake fertilizer or manure water was applied once every 15 days, and fertilization was stopped after beginning of autumn. If fertilization is continued after autumn, branches will grow wildly, which is easy to cause freezing injury in winter. When the tobacco leaves turn Huang Shi during the curing process, a small amount of ferrous sulfate can be added to the fertilizer.
"A flower is divided into six places, and ten leaves are heavy tables; Jade is pure and innocent, and gold is full. " This is the description of gardenia by the ancients. I believe that as long as you plant it patiently and carefully, you will definitely see its beauty.
