Gardenia likes fertilizer, so we should increase base fertilizer and apply topdressing frequently. Organic fertilizer should be applied as base fertilizer when changing pots for potted plants. Water every three days to keep the soil moist and avoid ponding, but spray leaf water and surface water frequently. Winter management: from cold dew to frost, when the temperature at night drops to 0 ?, pour enough antifreeze water. Potted plants can be safely wintered outdoors in the south to avoid wind and sunshine, while in the north, they need to be wintered indoors in the sun.
When applying fertilizer, adhere to the principle of "thin fertilizer and frequent application", and generally apply thin cake fertilizer and water every 1-2 weeks. During the period from bud emergence to flowering, quick acting phosphate fertilizer, such as 0.5% superphosphate solution, shall be applied for 2-3 times to promote the development and flowering of flower buds. Summer is the peak flowering period, and it can be moved to a cool and ventilated place. It is necessary to shade the sun to avoid exposure to the hot sun. It is also necessary to increase the number of leaf sprays to cool and moisturize the leaves, otherwise the leaves are easy to fall yellow.
During the growth period, 0.2% ferrous sulfate water (vitriol fertilizer water) should be watered once every half month, preferably alternately with other fertilizers, to promote the flourish of branches and leaves and the rich fragrance of flowers. For gardenias with fallen leaves caused by burning roots due to high fertilization concentration, change the pot immediately. Remove the soil on the outer layer of the root first, and then replace it with a new culture soil. Generally, after April of each year, when potted flowers move to the outside and plants begin to grow, topdressing should be applied.
How to raise fertilizer and water for potted gardenias The watering of potted gardenias is generally determined by the season, temperature, dryness and wetness of pot soil, plant growth or dormancy. After growing out of the water bacon, move it to the scattering bright place for culture, and use the comprehensive nutrient solution. Replace the nutrient solution once every 2-3 weeks. When the air is dry, spray it to the leaves to keep them fresh and bright.
In winter, it should be placed in a sunny place, and the room temperature above 5 ? can be safely overwintering. Gardenia jasminoides is a trifurcate branch, which is prone to branch disorder and affect the tree shape. The overlapping branches shall be pruned in time to make them dense and appropriate in length. Keep more water in the basin soil within one week, pay attention to water spraying to keep the environment moist, so that the seedlings gradually adapt to the changed environment, otherwise they will not survive after rooting or grow slowly.
Gardenia is easy to propagate by water transplanting. As long as the separate planting is timely and properly managed, the survival rate of seedlings is high. Water cutting propagation of Gardenia jasminoides is to insert cuttings into water to culture and root. There are many specific methods, which can be adopted according to the situation. Gardenia can be propagated by water cutting in combination with summer pruning. The strong twigs of the year should be selected as cuttings, with a length of about 13cm. Cut off all the leaves at the base of the cuttings.
Use a sharp knife to cut the lower part close to the stem node into a horse ear shape. The cutting mouth should be flat, and it is better to cut it with one knife. If there are few cuttings, they can be directly soaked in a vial. If there are many cuttings, they can be bundled into small bundles and soaked in water, or they can be drilled on a thin board with a hole spacing of 3~4 cm. Insert the cuttings into the holes respectively, and then place the operation board on the water surface. At this time, it should be placed in the seedbed for cultivation, otherwise the root system will not grow well and the nutrients will be insufficient, affecting the survival.
After cutting, it shall be cultured in a shady and humid environment. When the water temperature is about 20 ?, new roots can grow in more than 20 days. Pay attention to changing water gently each time, and do not damage the base of cuttings and new roots. Plastic bags can also be used to cover water containers. Summer is the peak flowering period, and it can be moved to a cool and ventilated place. It is necessary to shade the sun to avoid exposure to the hot sun. It is also necessary to increase the number of leaf sprays to cool and moisturize the leaves, otherwise the leaves are easy to fall yellow.
