How can potted gardenia blossom and flourish?

In the south of China, the unique warm and humid climate and slightly acidic soil and water make it easy to raise gardenia. For northerners, gardenias need careful care. If they are not careful, they will be pale and thin, rarely blossom, and die if they are heavy.

The elegant and fragrant gardenia with its white jade flowers and oily green leaves add a lot of coolness and fragrance to the hot summer and become people's favorite family potted flowers.

After several years of exploration, the potted gardenia has blossomed year after year in recent years, and has mainly done the following:

1. Select suitable basin soil

Gardenia jasminoides is an acid-loving flower with a suitable pH value of 5 to 6. If the soil acidity is not suitable, it will get twice the result with half the effort in the future management. Cultivation soil can choose rotten leaf soil, peat soil or retting sawdust plus half of the garden soil, avoid using old wall soil and cinder, with the market of gentleman orchid soil is more convenient and practical.

two。 Scientific watering

Gardenia likes moist soil and high air humidity. Keep the basin soil moist during the growth period from April to September. The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If it is dry and wilted, it will be bad for growth. 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. In the area of alkaline water in the north, tap water should be kept for two days before use. Every three or five days, add 0.5 grams of citric acid and 1 gram of ferrous sulfate to water once per liter to make the leaves oily and green.

3. adequate manuring

Gardenia likes to be fat. 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. In the growing season, the alum fertilizer made by cake fertilizer and ferrous sulfate retting is watered once a week, or 0.1% humic acid total nutrient organic liquid fertilizer can be used. Watering 0.1% potassium dihydrogen phosphate aqueous solution once or twice in the bud stage can make the flowers fat and fragrant. Fertilizer is stopped when the temperature is above 35 ℃ in hot summer and below 15 ℃ in autumn.

4. Bask in more sun

Gardenia likes light and can grow in semi-shade for a long time, but the flower branches are longer and the flowers are less. In addition to the strong light from July to August noon need shade and winter dormancy period, generally need to be maintained in the sun in order to blossom and flourish.

5. Good dormancy in winter

Gardenia can survive the winter in the open field in Qinling Mountains of China, but the root system of potted gardenia will be damaged after severe winter and recover slowly in spring. In the indoor with heating, although it is not damaged by freezing, the light is insufficient and the growth is thin. Most of the young buds formed in autumn fall off and blossom late in the second year. The better way is to put the potted flowers in a cold room of about 5 ℃ to make them dormant, or wrap the flowerpots with foam and other thermal insulation materials to protect the roots, and put them in the leeward and sunny place to overwinter, which can recover quickly in spring and bloom early.

6. Change basin soil at the right time

The seedlings are planted in small pots and gradually replaced into large pots. When the crown width is 2 to 3 times the caliber of the basin, it is time to change the basin. The growing season can be changed at any time. After pouring the basin, even the soil block is planted into the new basin, the caliber is about 5 centimeters larger than the original basin. Family potted plants when the pot reaches about 28 cm, generally no longer change the pot but only change the pot soil. It is better to change soil in March in spring. After pouring the basin, cut off part of the old roots, shake off half of the old soil, plant the new soil into the basin and pour water into the pot, put it in a warm semi-shady place, and keep it in the sun when new buds sprout.

7. Proper pruning

Gardenia jasminoides seedlings in the trunk 20 cm high to hit the top, leaving 3 to 4 branches, branches 2 pairs of leaves and then hit the top, promote branches, and then allow its growth. Lobular gardenia does not need to be topped. Trim lightly after flowering every year, cut off the inner chamber branches, diseased and weak branches, and some only grow short branches. When the crown width of Gardenia jasminoides is too large after 4 to 5 years, it can be strongly pruned after flowering, generally leaving 2 pairs of leaves in the upper part of the branch. After budding, the inward growing buds and the lower buds of the trunk will be erased, and the plant shape will become more compact and beautiful. Remember that gardenia can not be cut short in spring, otherwise it will not blossom in that year.

How to raise potted gardenias? How to make potted gardenia leaves luxuriant?

Gardenia, also known as Gardenia jasminoides, Gardenia jasminoides, is an evergreen shrub of Gentiana, Rubiaceae and Gardenia jasminoides. It likes warm, moist and sunny environment, is cold-resistant, semi-overcast and afraid of stagnant water, and requires loose, fertile and acidic sandy loam. Gardenia has luxuriant branches and leaves, evergreen leaves and fragrant flowers. It is an important garden ornamental plant. How to make potted gardenia leaves luxuriant? Let's take a look at the key points of maintenance:

1. Choose the right basin soil. Gardenia likes sour soil, soil, water and fertilizer contain alkali, so that the plant can not absorb iron, but affect the formation of chlorophyll, so that branches withered, leaves scorched, and even death. To use fertile, loose, well-drained acid soil, such as pine sawdust thoroughly mixed into the soil, the use effect is also very good.

two。 Scientific watering. Gardenia likes moist soil and high air humidity. Keep the basin soil moist during the growth period from April to September. The surface of the basin soil is watered when it is dry, and a spray can be used to pour water on the leaf surface at night. If it is dry and wilted, it will be bad for growth. 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.
