Although the white gardenia is plain and untouched, its white and quiet feeling has made many friends fall in love with gardenia. So, how to grow potted gardenias? It is also a good choice to place a pot of beautiful and fragrant gardenias at home to nourish your mood.

Gardenias like a sunny environment and can grow normally with proper shade. In a shaded environment, the leaves are dark green, but the flowering is poor, so shade is not recommended. Gardenia prefers a relatively humid environment, and is tolerant to both heat and cold (minimum -3°C). Prefers fertile soil, soil that is too poor will cause premature aging of the plant. Gardenia branches have strong germination ability and are resistant to pruning. Timely pruning is beneficial to the renewal of branches and plants. If the environment in your home can meet the above points, raising gardenias will not be a problem. However, you still need to grasp the following 7 key points when growing potted gardenias.

1. Choose suitable potting soil

Gardenias like acidic soil, and the suitable pH value is 5 to 6. Prepare appropriate soil before planting. soil. If the pH of the soil is not suitable, subsequent maintenance will be very troublesome.

The soil used for cultivation is usually leaf humus soil, peat soil and half of the garden soil. Do not use cinders, or directly purchase special soil for Clivia, which is convenient and practical.

2. Reasonable fertilization

Gardenias like fertilizer, but they need to be properly fertilized:

Add decomposed cake fertilizer to the soil as base fertilizer when planting.

During the growing season, use cake fertilizer and ferrous sulfate to make fertilizer water, and irrigate once a week. Fully nutritious organic liquid fertilizers can also be used.

Topdressing 1 to 2 times during the budding stage and watering with potassium dihydrogen phosphate aqueous solution can make the flowers enlarge and have a rich fragrance.

Stop fertilizing when the temperature is above 35℃ in summer and above 15℃ in autumn.

3. Scientific watering

Gardenia likes a moist and humid environment. During the growth period from April to September, keep the pot soil moist, water when it is dry and then when it is wet. You can spray the leaves to wet them at night to maintain humidity. If the plant is growing too vigorously, do not water it at night and water it in the morning after the sun comes out.

In northern water-logged areas, when watering, let the tap water sit for one day before watering. After 3 to 5 days, pour a little citric acid solution to keep the leaves green.

4. Get more sun

Gardenia needs sufficient sunlight to grow. If it is placed in semi-shade for a long time, the flower branches will be thin and slender. During maintenance, except for shading on 7/8 and noon and hibernation in winter, it can be maintained in the sun at other times.

5. Good winter dormancy

Although gardenias are cold-resistant, the root system of potted gardenias will be damaged after experiencing a severe winter, and recovery in spring will be slow. However, if placed indoors with heating, the temperature will be high and the light will be insufficient, the growth of the plant will slow down, and the flowering will be late in the second year. The best way is to place the potted plants in an environment of 5℃ to hibernate, or wrap the pots with insulation materials and place them outdoors in a sunny and leeward place to overwinter.

6. Prune appropriately

When the main trunk of the gardenia grows to 20 cm, cut off the top, leaving 3 to 4 branches to promote branching. After flowering every year, prune lightly and remove weak and diseased branches. However, the tops of gardenia branches should not be cut short in spring, otherwise it will be difficult to bloom that year.

7. Change the potting soil in a timely manner

Gardenia has strong vitality, and the seedlings can grow from a few centimeters to dozens of centimeters, so the potting should be changed according to the size of the plant. When the plant's branches are 2 to 3 times the diameter of the pot, it needs to be repotted. When repotting, you should promptly prune the old roots, replace half of the soil, water it thoroughly, and place it in a semi-shady place for a week. Move it to the sun after new shoots grow.

Plant care requires a certain degree of care: too much is not enough. Therefore, when planting gardenias, you also need to grasp the requirements for fertilizer, water, temperature, humidity, and soil. No more, no less is the most suitable.
