Gardenia (details)

1. Choose suitable basin soil.

Gardenia likes acidic soil, and the suitable pH value is 5 to 6. Prepare suitable soil before planting. If the pH of the soil is not suitable, the maintenance after that is very troublesome.

Cultivation soil usually choose rotten leaf soil, peat soil plus half of the garden soil, do not use cinder, or directly buy gentleman orchid special soil, convenient and practical.

2. Rational fertilization

Gardenia likes fertilizer, and rotten cake fertilizer is added to the soil as base fertilizer when planting.

Cake fertilizer and ferrous sulfate are used to make fertilizer and water in the growing season and irrigated once a week. Fully nutritious organic liquid fertilizer can also be used.

Topdressing for 1-2 times at budding stage and watering the aqueous solution of potassium dihydrogen phosphate can make the flowers fat and fragrant.

The temperature is above 35 ℃ in summer and 15 ℃ in autumn, and fertilizer application is stopped.

3. Scientific watering

Gardenia likes a moist environment. During the growing period from April to September, keep the basin soil moist, water dry and wet, and spray the leaves at night to maintain humidity. If the plant grows too fast, don't water it at night. Water it when the sun comes out in the morning.

In the northern alkali water area, when watering, the tap water will be watered after one day. For 3-5 days, pour a little citric acid solution to keep the leaves green.

4. Bask in the sun

The growth of gardenia needs plenty of sunlight, if placed in the semi-shade for a long time, the flower branches are thin and slender. During maintenance, in addition to 7 stroke 8 and noon need shade and winter hibernation, the rest of the time can be maintained in the sun.

5. Good dormancy in winter

Although gardenia is cold-tolerant, the root system of potted gardenia will be damaged after severe winter and recover slowly in spring. But in the room with heating, the temperature is higher, the light is insufficient, the plant growth slows down, and the flowering is later in the second year. The best way is to put the potted plant in a 5 ℃ environment to hibernate, or wrap the flowerpot with thermal insulation material and put it outside in the sunny leeward to survive the winter.

6. Proper pruning

When the trunk of Gardenia jasminoides grows to 20 cm, hit the top, leaving 3-4 branches to promote branches. After flowering every year, prune lightly and cut off weak and diseased branches. But gardenia can not be cut short in spring, otherwise it will be difficult to blossom in that year.

7. Change the basin soil at the right time

Gardenia is full of vitality, and the seedlings grow from a few centimeters to dozens of centimeters, so the pot should be changed according to the size of the plant. When the branch length of the plant is 2 to 3 times the diameter of the flowerpot, the pot needs to be changed. When changing the basin, you should trim the old roots in time, change half of the soil, pour water through, put it in the semi-shade for a week, grow new buds and move to the sun.

Pot gardenia conservation points elegant fragrant gardenia with its white jade flowers, oily green leaves, for the hot summer to add a lot of cool and fragrant, become people's favorite family potted flowers. 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. After several years of exploration, the potted gardenia has blossomed year after year in recent years, and has mainly done the following:

(1) choose 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.

(2) Scientific watering. Gardenia likes moist soil and high air humidity. Keep the 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) rational fertilization. Gardenia likes to be fat. 3% rotten cake fertilizer can be added to the culture soil as base fertilizer. During 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 the sun more. 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 the 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) pruning properly. 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.
