Gardenias bought by the florist basically have a lot of bracts, which are in bud. It seems that you can get a pot of fragrant gardenias when you buy them home, but! It's not true!
The gardenias we bought are basically raised in greenhouses. The gardeners have applied a lot of fertilizer in the early stage, so they all look alive.
It is much easier to raise Gardenia in the South than in the north. The south is hard to feed, the north is hard to feed, and there is not much nonsense. First, the flowers say some iron rules for gardenias:
1. Gardenia wilting is water shortage.
2. Yellow leaves and less water
3. If you don't bloom, you will lose light.
4. The cement must be replaced.
5. Do not touch water on the flower bud.
6. White leaves and iron deficiency fertilizer
7. Leaves are yellow and less fertilized.
Let's talk about how to raise gardenia.
Generally, Gardenia jasminoides Ellis is easy to wilt, because its leaves are relatively large, the water evaporates quickly, and the air humidity in the north is not as high as that in the south, which is easy to cause Gardenia wilt due to water shortage.
Another reason is that Gardenia from the greenhouse, the root system is damaged, directly affect the ability to absorb water, resulting in water shortage.
Solution:
1. Reduce branches, leaves and flowers. In this way, water consumption will be reduced and gardenia will be lightened.
2. Set of plastic bags to keep moisture. Cover the plastic bag, the evaporation of water will slow down, put it in a ventilated place, do not direct sunlight. Open it for half an hour at night to breathe.
3. Water by soaking. Put the Gardenia basin in the basin with water, the water surface is 2 /3 below the soil surface.
Principle of watering: low temperature and less pouring, high temperature and more pouring. Generally, water once every 2-3 days. You can spray water around the flowers every day to increase the air humidity.
1. The reason why gardenias don't bloom has little to do with humidity. The main reason is that the light is not enough. The simplest and rough way is to let them bask in the sun.
2. There are three conditions for flowering: sufficient light, certain temperature difference and fertilizer. There are flower buds but do not bloom, then the sun must be right, a certain temperature difference plays an auxiliary role, enough fertilizer is the basic condition to be able to gestate flower buds.
3. Sometimes it will be found that the flower bud will fall when it grows. There are two reasons: the first is too much water, the second is insufficient nutrition.
① Gardenia likes to be wet, but it doesn't mean to water every day, which makes water easy to rot, so it needs ventilation! In addition, when spraying water on the leaves, do not spray it on the buds! Otherwise, I'll show you immediately.
② when there are more bracts, you should know how to choose between them. If you cut off the small ones and leave the big ones, the leaves will be too thick and absorb the nutrition needed for flowering. You should cut them off in time
③ in flowering stage, phosphorus and potassium fertilizer should be applied to promote flowering, such as potassium dihydrogen phosphate solution, less nitrogen fertilizer.
If the Gardenia at home is dropping its flower bud, move to a ventilated place, cut off the stronger leaves under the flower bud, and don't spray water on the rest of the flower bud through the sun through the glass, so that they may still be saved.
1. Many Gardenia bought by people are made of clay. Although this kind of soil is not lack of iron, it affects the absorption ability of the flower to iron. It has poor air permeability and cannot be watered thoroughly. Generally, it needs to be replaced.
To judge whether it's clay, dip wet hands into pot soil to see if it's sticky. It's clay.
2. If you use loess to raise, you will not need to change soil urgently. You can raise it until it blooms.
3. Some gardenias will have buds when they are bought. Don't change pots unless you don't want to see flowers.
4. It should also be noted that do not fill the basin, that is, directly move the root soil into another soil. Either the original soil basin, or wash the root for basin for soil
5. The soil suitable for Gardenia growth can be prepared with coarse sand, perlite and peat soil in the proportion of 1:1:2. A little luxury can be replaced by a little red jade soil.
The principle of changing basin: good ventilation, the root and basin can be the same size; the basin soil is very loose and breathable, and you can choose a larger flowerpot; if the flowerpot is well ventilated, such as tile basin, porous plastic basin, the basin can be used a little bigger.
1. If the new leaf vein of gardenia is green and the leaf is white, it means that it lacks iron.
① take ferrous sulfate of rice grain size and add 2 bottles of mineral water to mix it into solution, and spray it on the leaf surface. Spray once every half a month.
However, ferrous sulfate is easy to be affected with damp due to its small dosage each time. To supplement microelements, it is convenient and effective to use home-made decayed rice washing water and peel water. The production method can search the articles before Huahua
2. Too much fertilizer will also lead to gardenia yellow leaves, so we must control the quantity and not be greedy.
3. It must be reminded that gardenias just bought back from the slow seedling stage, gardenias just changed soil, and gardenias when the temperature is lower than 20 ℃, do not apply fertilizer, do not apply any fertilizer!
North flower friends now this time to buy Gardenia will be easy to feed some, are basically with a bud, do not experience the test of temperature conversion, the bigger the bud, the easier to open, interested can try
