How long does it take for the seedlings of gardenia to bloom and bear fruit
This article brings you the content of gardenia seedlings blooming and bearing fruit in a few years and the planting methods of green plants and flowers. Next, the editor will introduce to netizens.
Gardenia, evergreen throughout the year, with glossy leaves, white flowers, aromatic, edible, and both fruit and whole plant can be used as medicine. It is a type of ornamental leaf, ornamental flower, medicinal, and aromatic flower that is deeply loved by the public and relatively common. There are many varieties such as large leaves, large flowers, small leaves, small flowers, single petals, and double petals; most gardenias do not bear fruit or bear very small fruit after flowering, there is a single-petal mountain gardenia, not only the flowers are large and aromatic, but also the fruit is large and plump, the seed coat is orange or reddish orange when mature, and it can be dried for medication.
Key points of cutting propagation technology for gardenia
Gardenia can be propagated by methods such as sowing, cutting, dividing plants, and layering, among which cutting propagation is the most commonly used. It can not only propagate and cultivate a large number of seedlings at one time but also does not cause mutations and can maintain the original characteristics and excellent varieties of the parent plant. It can also shorten the seedling bed period and提前 flowering compared to sowing propagation, usually blooming 2-3 years after cutting.
Gardenia is usually propagated by cutting from March to October every year; if protective facilities for seedlings are used, cutting propagation can also be carried out from November to the following February; the best cutting time is before spring germination and from August to October in autumn.
When cutting gardenia, it is suitable to choose healthy, disease-free, and pest-free branches from the previous year or semi-woody new branches of the current year, cut into sections of 3-5 leaf nodes, leaving 1-2 upper leaves, and removing the rest of the leaves. The upper incision should be flat and the lower incision should be oblique, shaped like a horseshoe, and the cut branches should be put into a basin of water one by one. After cutting, treating the cuttings with rooting powder before planting can help improve the survival rate.
Gardenia can be propagated by water cutting; river sand (including vermiculite, perlite) or river sand can also be used for cutting; peat or garden soil, pond mud, and surface soil of mountains can also be used, mixed with 30%-40% river sand or rice chaff ash, charcoal dust, fly ash, etc., 10% superphosphate, mixed evenly as the cutting matrix; floating foam plates can also be used for cutting floating seedlings; seedling trays, nutrient bags, nutrient cups, nutrient bowls, grass bowls, paper bags, or various pots can also be used for cutting seedling propagation.
The depth of cutting into the soil for gardenia is 1-3 leaf nodes, pressing the cutting matrix while inserting to make the cutting fully contact with the matrix. After cutting, spray once with a 12% green copper emulsion 600 times solution or a 50% carbendazim wettable powder 1000 times solution for disinfection. Then, spray water to keep the moisture. In winter and spring, pay attention to拱膜 insulation, generally maintaining the cutting environment temperature at around 20°C and the relative small environment humidity at about 75% is best; in summer and autumn, promptly cover with shading netting, grass curtains, bamboo curtains, or use sunshade netting, shading 80%-90% is good, and pay attention to ventilation and cooling. It is best to use full-day mist cutting seedlings, which can effectively improve the cutting survival rate of gardenia.
Generally, gardenia can take root and survive 20-30 days after cutting. For water cutting, the water should be changed frequently, and after taking root, it should be moved to the seedbed or cultivated in soil with nutrient bags, nutrient bowls, nutrient cups, etc. For floating cutting and sand cutting, the seedlings should also be moved to the seedbed for soil cultivation after taking root and surviving.
Key points of shaping technology for gardenia
Gardenia can be shaped using the "combined cutting and binding" method. Generally, during the growing season, appropriate thickness of copper wire, iron wire, lead wire and other metal wires, or coir, coir rope, ramie silk, etc., are selected to tie the main branches for shaping, and the rest of the branches and leaves are pruned and processed. Before tying, carefully observe and think, cut off branches unrelated to the shape; when tying, be careful to prevent breaking the branches or damaging the bark. After shaping, promptly remove the tying material to prevent wire embedding, which affects the appearance of the shape and the normal growth of the plant; generally, untie every 3-4 months, and for those that are not tied in place at one time, it can be retied for the second or third time until the shape is fixed.
Gardenia can also adopt the "complete pruning" method of the Lingnan school, namely the "branch storage and trunk cutting" method, for processing and shaping. During the growing season, remove excess sprouts, and promptly remove old yellow leaves. For branches that need to be "stored and cut", they should be pruned short after reaching a certain length and thickness, and after the new shoots grow to a certain length and thickness, they should be pruned short again for shaping. Repeat this process until the shape is fixed. When shaping with "branch storage and trunk cutting", pay attention to the extension changes in different directions such as height, density, length, distance, left and right, and up and down between branches and branches.
Potted gardenia is often processed into various forms such as natural开心 shape, natural large tree shape, curved stem style, prone stem style, cliff style, near-water style, root lifting style, and stone-attached style. The branches and leaves can be pruned into natural shape, cloud shape, steamed bun shape, umbrella shape, hemisphere shape, and spherical shape.

Key points of移植ing and potting gardenia
Gardenia is suitable for transplanting and potting before spring germination or from September to October in autumn. If using nutrient bags, nutrient cups, nutrient bowls, grass bowls, and other seedling containers for cultivation, transplanting and potting can be done all year round. After transplanting and potting in winter and spring, pay attention to keeping warm and preventing cold and frost; after transplanting and potting in summer and autumn, pay attention to shading, spraying leaf mist, and ventilating and cooling the environment. Winter and spring transplants should be done on warm sunny afternoons; summer and autumn transplants should be done on cloudy or rainy days. For bare-root transplants, it is best to soak the roots in clean water for 5-6 hours first, then dip the roots in thick mud before potting.
Gardenia should choose purple sand陶盆 or glazed陶盆 of appropriate size, depth, and shape according to the size of the tree trunk and the shaping form, or unglazed pots, mud pots, tile pots, wooden pots, rattan pots, etc. can also be used for planting. Pad the bottom drainage holes of the pot with small stones, tiles, broken pot pieces, etc., and place some decomposed animal bones, hoof slices, etc., as base fertilizer, and fill in with a mixture of 4 parts of peat soil, decomposed leaf soil or garden soil, mountain surface soil, pond mud, etc., 3 parts of river sand, coal slag or rice chaff ash, mushroom residue, etc., 2 parts of decomposed high-quality farm manure, livestock manure, compost or cake fertilizer, salt-free bone meal, etc., and 1 part of pine needle soil, coconut shell powder, and superphosphate.
When potting gardenia, adjust the direction and position according to the shape of the tree trunk, fill in the cultivation soil while pressing, and make the cultivation soil fully contact with the roots of gardenia. After planting, water thoroughly, place in a well-ventilated area without direct sunlight, and after 2-3 weeks, depending on the growth of the plant, gradually transition to normal maintenance management.
