Gardenia seed cultivation methods and precautions

Seed selection: gardenia can select full and mature fruit, cut off the epidermis after drying, take out the seeds and put them in hot water, select the full seeds that sink to the bottom of the water, dry them and sow them. Sowing: generally carried out before and after spring and the Autumn Equinox, the seeds are mixed with ashes and put into the soil, covered with fine soil and then covered with grass, the soil is watered thoroughly, and the soil should be kept moist during the growth period. Raising seedlings: seedlings will emerge in about 20 days, uncover the grass in time after emergence, and then do a good job in field management.

I. methods of raising seedlings with seeds

1. Seed selection

Select ripe fruits with full and dark red color, dry them with shells and make seeds, then cut off the seed epidermis with scissors, take out the seeds, rub them in hot water, pick out floating seeds and impurities, and fish out the abundant seeds that precipitate at the bottom of the water. put it in a ventilated place to dry the excess water, and then sow.

2. Sowing seeds

Gardenia seeds are suitable for sowing in spring, or before and after the Autumn Equinox in autumn. You can choose to sow in deep, loose and fertile sandy loam, mix the seeds with fire ash, put them evenly into the soil, cover the seeds with fine soil or fire soil, and finally soak the soil thoroughly with grass, and keep the soil moist during the growth of the seeds.

3. Raising seedlings

Gardenia will emerge about 20 days after sowing, remove the cover grass in time after emergence, grow seedlings when the seedlings grow to 2-3 true leaves, and keep no weeds growing in the container. Autumn sowing can be fertilized 2-3 times in the first year, once in spring, summer and autumn in the second year, once in spring, summer, autumn and winter in spring, summer, autumn and winter respectively, and sowing in autumn to the end of autumn and early winter in the second year. When the seedlings grow above 30cm, they can be planted, and those sown in spring need to be planted in the spring of the second year, when the seedlings reach 30cm.

II. Management of seedling colonization

1. Basin soil

The planted basin soil can be used mountain soil, or mixed with 2 parts of river sand, 4 parts of rotten leaf soil and 4 parts of vegetable garden soil. Gardenia likes to be planted in fertile, loose and acid soil with good drainage, and the suitable soil PH value is between 4 and 6.

2. Temperature

Gardenia likes to grow in a warm environment, the suitable growth temperature is 16-18 ℃, high or too low temperature will not be conducive to its growth, so in the summer high temperature season, to properly reduce the indoor temperature, winter low temperature season need to do a good heat preservation measures, summer and winter can be placed in the indoor ventilated place for breeding.

3. Watering

Gardenia likes to grow in a humid environment, and has relatively high requirements for soil moisture and air humidity. During the growth period, it is necessary to ensure that there is sufficient water, which can be watered properly, and at the same time, it can also spray water to the leaves or indoors to improve the humidity in the air. It is necessary to reduce the amount of water in winter to avoid excessive water accumulation and cause rotting roots of the plant.

4. Fertilization

The demand for fertility of Gardenia jasminoides is not very high, but in the peak growing season, it can be fertilized every 14 days or so, which is conducive to its more luxuriant branches and leaves and more beautiful flowers.

5. Pruning

During the growth of Gardenia jasminoides, the branches and leaves are easy to overlap and affect ventilation, so it can be pruned appropriately, which can promote its better growth and branching, and the residual branches can be pruned in time after flower fade, which is helpful to preserve nutrients and promote shoot germination.

Matters needing attention in aquaculture

The main results are as follows: 1. After transplantation, sufficient root water should be poured in time, and the soil should be kept moist, but stagnant water should not appear and rotting roots should be avoided. Before blooming, it is necessary to apply fertilizer and water thinly and frequently.

2. The row spacing of planting seedlings depends on the use of producing Gardenia jasminoides. The depth and width of planting pits for cut flowers and ornamental plants in public places are about 50cm. It is generally appropriate to plant seedlings in the dormant period. If it is necessary to carry soil mass in the growing period, it is helpful to improve the survival rate.

3. Planting gardenia in open field has strong adaptability, extensive planting management and easy success, so it is suitable to be planted in acidic and slightly acidic plots with semi-shade, fertile soil, loose and good drainage.
