Culture method of lobular gardenia

Lobular gardenia, also known as Gardenia jasminoides, Fructus Gardeniae, etc., is an evergreen shrub plant of Rubiaceae. Gardenia is cultivated in most parts of our country, and its ornamental value is very high. It can be planted in clusters or configured on the edge of the forest, in front of the court, in the corner, by the side of the road, and can also be used as balcony greening, potted flowers, cut flowers or bonsai. Let's take a look at the breeding methods of lobular gardenia.

Growth habits of Gardenia variegata

Lobular gardenia is a typical acidic flower, which likes warm and humid climate, is not cold-resistant, has good sunshine but can not withstand strong sunlight, and is suitable for growing in loose, fertile, well-drained and lightly clayey acidic soil. It can only be used as potted flowers in greenhouse in Northeast, North China and Northwest China. Resistant to sulfur dioxide and can absorb sulfur to purify the atmosphere.

Propagation method of Gardenia jasminoides

1. Sowing: Fructus Gardeniae is mainly propagated by seeds, mostly in spring, but the seeds germinate slowly, germinate about 1 year after sowing, blossom after 3-4 years, and it is not easy to receive seeds in pot plants in the north.

2. Cuttage: from October to November in the north, it can be cut at any time from April to the Beginning of Autumn in the south, but the survival rate is the highest between summer and autumn. 2-year-old branches with healthy growth are selected for cutting. when the rooting seedlings begin to grow, they can be transplanted or put on the pot for a single plant, and can bloom after 2 years.

3. Crimping: in April, strong branches were selected from 3-year-old mother plants for striping. If there are trigeminal branches, three seedlings can be obtained at the fork at one time. Generally, it can take root after 20-30 days, can be separated from the mother plant in June, and can be planted separately or single plant in the next spring.

Culture method of lobular gardenia

1. Soil: gardenia microphylla should choose acidic basin soil with a suitable pH value of 5 to 6. Cultivation soil can choose rotten leaf soil, peat soil or garden soil with half of retting sawdust, and avoid using old wall soil and cinder.

2. Watering: the soil surface of the gardenia gardenia flowerpot can be watered when it is dry, and can be watered to the leaf surface with a spray can at night. 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.

3. Fertilization: 3% rotten cake fertilizer was added to the lobular gardenia culture soil as base fertilizer, the alum fertilizer made by cake fertilizer and ferrous sulfate retting was irrigated once a week during the growing season, 0.1% potassium dihydrogen phosphate aqueous solution was irrigated once or twice in bud stage, and the fertilizer was stopped above 35 ℃ in summer and below 15 ℃ in autumn.

4. Lighting: lobular gardenia has good sunlight but can not withstand strong sunlight. It can also grow in semi-shade for a long time, but it must maintain 60% light throughout the day in order to meet its growth needs.

5. Change the pot: when the crown width reaches 28 cm or so, change the potted soil in the family potted gardenia. If it is to change the pot, it is better to plant the soil into the new pot, usually in spring March.

6. Pruning: the lobular gardenia leaves three main branches according to the shape of the tree, and the other branches sprouting from the roots should be cut off at any time. Remember that the top of the branch should not be cut short in spring, otherwise it will not blossom in the same year.

7. Overwintering: the root system of the lobular gardenia will be damaged after the severe winter in the north, and it will only recover in spring, so it is necessary to wrap the flowerpot with foam and other thermal insulation materials to protect the root system and put it in the leeward and sunny place to overwinter.
