Gardenia flower watering method

1, the correct watering time of gardenia.

If it is winter, you should choose to water at noon. At this time, the temperature is relatively high and the roots will not be frostbitten. In spring, autumn and summer, it is best to water it in the morning, and then put it in a ventilated and sunny place.

2. What water does gardenia water?

As we all know, gardenia likes acidic soil, so when watering, alkaline water must not be used. When watering, it is better to rain; When watering flowers with tap water, you can add a little white vinegar or citric acid to enhance the acidity of the soil.

Exclusive formula

1, citric acid: one liter of water to 0.5g of citric acid.

2, vinegar: a liter of water plus 3 ml of vinegar.

3. Orange peel: soak in fresh orange peel until the water quality is yellowish.

4, Taomi water: Taomi water can be used, but don't use it often, just once a month.

3. Detailed watering methods of gardenia.

Water is usually done in the morning in spring and summer. When the temperature is high, when the sun goes down, that is, when we go home from work, we spray water on the leaves. When spraying water, pay attention to the direction of the nozzle, don't spray it, and don't spray it on the already opened flowers. Pay attention to ventilation after spraying water.

The water from April to September should be dry and wet. Don't water it every day, lest the leaves on the plants turn yellow. In July and August, the weather is dry, the water evaporates quickly and the soil is easy to dry. According to the soil conditions, you can water it every day.

On the second day after watering, loosen the soil appropriately according to the soil conditions. After a few more days of watering, the soil is still moist and ventilated. When changing pots next year, we need to pay attention to the choice of soil matrix, and we must be loose and breathable.

How to plant gardenias?

1, choose gardenia with dark green and shiny leaves. When choosing gardenias, we should know that most varieties of gardenias are suitable for tropical and subtropical climate. Hardy of Kleim is the only gardenia variety that can tolerate cold.

2. Choose the planting site. Gardenia needs all or part of the light. They need warm sunshine to grow up healthily. Sunshine in the morning is better than sunshine in the afternoon. If you plant it in an indoor flowerpot, you need to put it by a window facing south, so that you can get warm indirect sunlight during the day.

3. Choose high-quality soil. Gardenia is suitable for planting in wet but well-drained acid soil. PH 5 or 6 is best. You can test the soil in advance and then replenish the missing nutrients. If the alkalinity of clay is too high, sulfur can be added.

4. Don't be too close to the cement. Gardenia can be planted outside the window, so that you can smell the flowers, but not too close to houses or walkways. The soil near the cement is highly alkaline, which is not suitable for gardenia growth.

5. Add organic matter to the soil. Gardenia likes nutritious soil. Adding fertilizer, sphagnum or manure can promote the growth of plants and plant them in prepared places. Spring and autumn are suitable for planting. If you plant more than one gardenia, leave 1- 1.8m between two gardenias. The width of the dug pit is twice as wide as that of the root system and the depth is the same as that of the root system.

6, if planted in a flowerpot, also according to the above requirements-the flowerpot should be wide enough, twice as wide as the root system of gardenia.

7. Plant gardenias in the pit. Fill in half the soil and water it.

8. Water before filling all the soil can avoid bubbles, and cover the roots of gardenia with plastic film. Pine needles have the best effect of protecting roots, which can increase the acidity of soil. Before plants take root, keep the surrounding soil moist. The plastic film should be about 5 cm thick, but don't touch the roots.

Gardenia flower maintenance method

1, Soil: It is appropriate to cultivate with rich and fertile acidic soil containing humus, which is the key to the success of family planting in the north. Generally speaking, rotten leaves can be added with 1 serving rotten bean cake fertilizer and a certain amount of ferrous sulfate at the same time, or drenched with 0.2% ferrous sulfate or organic fertilizer water for 3 ~ 5 times after taking.

2. Cultivation: When planting with cutting seedlings and layering seedlings, it is necessary to ensure that the roots of the plants are fully stretched. At the same time, the density of filling soil is about 85% with fine soil, and the depth is about 1 cm above the root system. Water it in time after planting, and it is generally advisable to seep through the bottom of the basin.

3. Change the pot: generally, the pot should be turned once every two years, preferably in spring. In order to effectively prevent the pot soil from alkalization, you can turn the pot once a year and fasten the pot button before changing it. You can stop watering when the pot is slightly loose after it is dry, about 10 days. When changing pots, cut off some roots, such as the roots of pests and diseases, over-breed the roots, and then plant them again.

Pest control: scale insects, red spiders and soot diseases occur in gardenia in summer when it is hot and poorly ventilated. 40% dimethoate EC 1000 times can be sprayed to control individual scale insects, 40% triaminomethanol EC 1000- 1500 times can be sprayed to control red spiders, and the occurrence of soot disease can also be reduced. For the sake of safety, washing powder solution can be sprayed at home, which also has certain effects.

5. Trimming: Generally, it is carried out in spring, cutting off long branches, weak branches and other disorderly branches that affect the plant shape, keeping gardenia with beautiful plant shape as the top, and picking the top appropriately in the growing season to promote the growth of flower branches and increase the number of flowers. 6. Management and maintenance: Gardenia requires high air humidity. The principle of watering is to dry thoroughly, and it is best to water with rainwater, snow water or fermented rice washing water. During the growing period, water containing 0.2% ferrous sulfate or fertilizer water is poured every 7 ~ 10 days. Gardenia should be placed in a cool place with scattered light in summer, and should be watered and sprayed frequently in spring, summer and early autumn to increase humidity. It is advisable to put sunshine in winter, stop fertilization and water too much. You can often wash the leaves with water close to room temperature to keep them clean, especially in rooms with heating in the north. Don't put the flowerpot in front of the radiator or air conditioner to avoid dehydration of the leaves.
