When do gardenias need to be fertilized?

Gardenia fertilization time.

Gardenias need to be reasonably supplemented with fertilizer during the growth period. Apply rotten human manure or cake fertilizer every 10 days or so, stop watering 1 day before fertilization, and water once at the same time on the day of fertilization. Fertilization will be stopped from mid-September.

For adult plants, in mid-June and mid-August, apply sesame paste residue once each, 1 tael each time, and mix well with the topsoil after crushing.

Gardenia fertilization method.

1. Gardenia should be applied to cooked soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not apply fertilizer during the hibernation period.

2. Stop watering gardenia before fertilization, and water thoroughly when fertilizing.

3. Gardenia peanuts are long-term, and the appropriate amount of fertilizer should be applied more when flowering, and fertilizer should be added once after flowering.

4. If the gardenia has been planted for less than three years, do not apply human feces. Excessive nitrogen fertilization will result in thick branches, large leaves, and thick green, but no flowering. Lack of phosphorus and potassium fertilizers can also occur without flowering or flower buds.

Withered and shedding.

Gardenia fertilization precautions.

Gardenia likes fertilizer, but can not add too much fertilizer at one time, must be thin fertilizer more, must not be greedy, otherwise it will cause thick branches, large leaves, thick green, it will lose its own appreciation effect.

The reason why mast flowers do not bloom.

1. Improper water and fertilizer, once the water and fertilizer are excessive, it will cause the plant to grow, and the reproductive growth will not have enough nutrients will affect the formation of flower buds, resulting in no flowering or very little flowering, some of them will open, and even fall off immediately. In the flower bud differentiation stage, special attention should be paid to the combination of phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate.

solution, which is conducive to the formation of flower buds and pregnant buds; Excessive fertilization during the pregnancy bud period, and the amount of watering will also cause flower and seedling fall.

2. The light is not suitable, the choke flower likes shade, special attention should be paid to the light that is too strong in summer and too weak in winter, and the light is too strong and too weak will affect the flowering of mast flowers.

3. The soil has high alkali content, and the choke flower likes acidic soil, and the soil of cultivating mast flower has high salt and alkali content, which will cause yellowing of the plant, which will eventually affect flowering.

4. Without pruning and shaping, the mast, flower branches are messy, a large number of miscellaneous branches consume a lot of nutrients and the branches are too dense, which affects photosynthesis.

are all important reasons for not flowering.

5. Serious pests and diseases, I believe everyone can understand, serious pests and diseases will inevitably cause the loss of flowers and storage.

What fertilizer is good for gardenias, try this, the flowers are many and fragrant.

Apply plantar fertilizer. In the process of maintenance, gardenia grows slowly, the branches are thin, and frequent top dressing is required, indicating that the bottom fertilizer is insufficient during planting. Before planting gardenias, organic fertilizer (rotted animal manure, cake fertilizer) is added to the soil and mixed evenly with the soil.

Apply slow-release fertilizer. In fact, most families raise flowers, the number of fertilization is small, and even not often take care of it, in order to facilitate and save trouble, agricultural scientists have developed a lazy fertilizer - slow-release fertilizer. If the fertilizer is applied in a pot, the fertility in the fertilizer will be released slowly, so there is no need to worry about the damage to the plant if you apply too much fertilizer.

However, fertilization is stopped after October and during flowering.

Fertilization method: It is advisable to apply cooked soybean cakes, sesame sauce residues, peanut bran and other fertilizers, which can be acidic after fermentation and rotting, but must be applied with thin fertilizer, avoid thick fertilizer, raw fertilizer, and do not fertilize during hibernation. If it has been planted for less than three years, it is important not to apply human feces.

Excessive nitrogen fertilization will result in thick branches, large leaves, and thick green, but no flowering. When phosphorus and potassium fertilizers are deficient, there will also be no flowering or flower buds wilting and falling off.

Fertilization time: After planting, weeding and topdressing in spring and summer every year, human and animal manure, manure, compost, cake fertilizer, etc. can be applied. Before flowering in summer, it is better to apply fertilizer with more phosphorus and potassium content, and fertilization is generally carried out after weeding and loosening the soil.

Precautions: The day before fertilization, the soil should be loosened, which is conducive to the absorption of nutrients by plants and achieves the best fertilizer effect; Water the next day after fertilization to avoid fertilizer accumulation in the soil and cause fertilizer damage.

Fertilization needs to keep these time points in mind: fertilize after the beginning of spring, do not apply after the autumn equinox; Fertilize the buds now, but not when the buds crack; Apply fertilizer on sunny days before the rain, but not after the rain; Fertilize the potting soil when it is dry, and do not apply it when it is wet; Thin fertilizer is applied frequently, and thick fertilizer is not applied; Fertilize before and after flowering, and do not apply during flowering; Fertilize in the morning and evening, and do not apply at noon; Strong seedlings are applied more, and weak seedlings are not applied.

Gardenias need to be topdressed with phosphorus and potassium fertilizer before flowering, and no fertilization is required after flowering. During the flowering period of gardenias, it is necessary to control the light in the environment to ensure that the scattered light is sufficient. Control the temperature of the environment, up to 30, but also need to control the watering, keep the soil moist, and there should be no water accumulation.

In the process of cultivating gardenias, the growing season needs to be topdressed in time to ensure the growth of the plant, and before the gardenia blooms, it is also necessary to apply phosphorus and potassium fertilizer once to promote the flowering of the plant. Do not fertilize the gardenia after it blooms, at this time, once the fertilizer is improper, it is easy to cause fertilizer damage, causing the gardenia to wither in advance.

1. Control the lighting

During the flowering period of gardenias, it is necessary to give them sufficient scattered light, which is more conducive to the absorption of nutrients by plants, so that gardenias bloom more gorgeously and have a longer flowering period. When the light is too strong, pay attention to shading to avoid damage to the plants caused by strong light.

2. Control the temperature

Gardenia also needs to control the temperature of the environment during the flowering period, to ensure that the temperature is not more than 30, and the minimum is not less than 15, which can ensure the growth of the plant during the flowering period and effectively prolong the flowering period of gardenias.

3. Control watering

During the flowering period of gardenias, the amount of watering must be controlled, and watering should be carried out strictly according to the dryness and humidity of the soil, and the soil can be kept moist, and no water accumulation shall occur. If overwatering causes water to accumulate in the potting soil, the roots of the plant will rot and the flowers will fall early.

During the flowering period of the plant, do not apply fertilizer, otherwise the buds and flowers will fall off.

Raise gardenias, fertilize with this method, the leaves are green, the buds are many, and the flowers are beautiful!
